The compatibility of the black masterbatch is one of the factors that determine the quality of the masterbatch. If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other infusible polymers. This will cause some unpredictable troubles that are difficult to restrain, and waste the time and raw materials of the final consumer. At this time, the base resin can be used to produce high-quality masterbatch, and the masterbatch has good compatibility during the melting process.

The commonly used black masterbatch technology is a wet process. The color masterbatch is made by water phase grinding, phase inversion, water washing, drying, and granulation. Only in this way can the product quality be guaranteed. In addition, while the pigment is being ground, a series of masterbatch technology tests should be carried out, such as measuring the fineness of the sand slurry, measuring the diffusion performance of the sand slurry, measuring the solid content of the sand slurry, and measuring the fineness of the color slurry, etc. project.

The black masterbatch is generally composed of three parts. The colorant carrier dispersant is mixed by a high-speed mixer, crushed, and extruded into pellets. The color masterbatch has high concentration, good dispersibility and cleanliness during plastic processing. And other significant advantages.

Now let me introduce to you what are the production requirements of the masterbatch. For the color materials used in the masterbatch, attention must be paid to the matching relationship between the colorant and the plastic raw materials and additives. The selection points are as follows.

The pigment cannot react with resin and various additives, and has strong solvent resistance, low migration and good heat resistance. In other words, the masterbatch cannot participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastic, so carbon black material cannot be added to polyester.

Due to the high molding processing temperature of plastic products, the pigment should not decompose and change color under the conditions of molding heating temperature. Generally, inorganic pigments have better heat resistance, while organic pigments and dyes have poor heat resistance. This point should be paid attention to when choosing pigments.

The dispersion and tinting strength of the pigment should be good. When the pigment is unevenly dispersed, it will affect the appearance of the product; when the coloring power of the pigment is poor, the amount of the pigment will increase and the material cost will increase. The same colorant has different dispersibility and tinting power in different resins, so you should pay attention to this when choosing a colorant.

The particle size of the pigment is also related to the dispersibility. The smaller the particle size of the pigment, the better the dispersibility and the stronger the coloring power. Other properties of the colorants should be understood. For example, for plastic products used in food and children’s toys, the color should be non-toxic; for plastic products used in electrical appliances, a color with good electrical insulation should be selected; for outdoor use For plastic products, color materials with good weathering resistance should be selected.

According to statistics, our country needs about 79.32 million tons of raw material paper and pulp every year, most of which are wood and reed resources. The shortage of raw materials caused by the massive consumption of raw materials is born, and a large amount of waste will be discharged during the papermaking process, which will damage the earth. The ozone layer and the damage to the function of filtering ultraviolet rays have caused great pollution to the environment. Therefore, the development of this energy-saving, environmentally friendly, and soluble stone paper is a manifestation of protecting the environment, protecting the ecological balance, and developing a circular economy.

There are abundant limestone mineral resources in various regions of our country. The production of inorganic powder environmentally friendly stone paper has the value of enhancing and expanding the application of our country. It has also greatly promoted the development of my country’s paper industry and polymer material processing industry, and has a harmonious development. The advantages of the environment, expanding domestic demand, and stimulating local economic growth.

The production process of stone paper products is simple, raw materials are easily available, high output, low energy consumption, no pollution, no plant fiber and no cutting wood are used to protect the important characteristics of natural ecology, and it is a pure natural green environmental protection product. The products produced also have the advantages of moisture resistance, folding resistance, tear resistance, mothproof, non-toxic, odorless, high printing definition, good effect, and degradability.

Stone paper products are used in packaging paper, office paper, advertising paper, special paper and other fields. It can be made into color books, disposable paper bowls and cups, promotional albums, product manuals, desk calendars and other products.

Stone paper is a kind of paper made of inorganic powder and environmentally friendly stone. It can be said to be a revolution in the paper industry after Cai Lun Paper. It solves the reduction of forest area caused by the large-scale felling of trees as raw materials for paper products. Tension problem. So what is the main principle of stone paper? Let us understand it together!

Let’s first talk about the main production principle of stone paper. At present, paper is produced through wood processing. It is stone paper that uses a widely distributed limestone mineral resource as the main material, mainly this kind of stone. It contains about 70% calcium carbonate, and the high molecular polymer that can be combined with it is processed by chemical principles and special processes, and the polymer is extruded and blown to produce the same effect as paper made of plant fibers. Not only that, it also has the important core properties of plastic bags. The biggest advantage of this kind of stone paper is that it will degrade and return to nature after being discarded, which solves the problem of white pollution.

The raw material of stone paper is relatively low-priced ore powder. It has a wide distribution and large reserves. Almost every ton of inorganic powder and environmentally friendly stone will be 30-40% lower than that of plastic bags, which is lower than some high-grade wood pulp paper. The cost is lower by 20%. This is an innovation of polymer materials, not only for the relationship of cost and profit, but also a manifestation of the continuous development of human science to research and promote the goal of saving and environmentally friendly Struggle is an important advance to protect the earth.

Stone paper is a new type of material between paper and plastic. It can not only replace part of the traditional functional paper, professional paper, but also replace most of the traditional plastic packaging. And it has the characteristics of low cost and controllable degradation, which can save a lot of cost for users without causing pollution.

From the perspective of replacing the traditional part of paper, it can save a lot of forest resources for the society and reduce the secondary pollution generated in the papermaking process; from the perspective of replacing the traditional part of plastic packaging, it can save a lot of strategic resources for the country. , The product can be degraded after use, and will not cause secondary white pollution.

The environmental protection new material stone-paper industry has a wide range of materials, and the space for product upgrades, technology upgrades, and application areas is very broad. It is a very vigorous and well-developed industry.

The production process is simple; the investment is large, the output is high, and the energy consumption is low; it does not use plant fibers and does not cut trees, which can save a lot of wood and protect the natural ecology; it does not need to add strong acids, alkalis, bleaching agents and other chemical raw materials, and does not discharge waste water , Waste residue and toxic and harmful gases are green environmental protection products.

The main advantages of environmentally friendly stone paper are as follows:

Environmental protection materials, energy-saving technology, no pollution (no strong acid, no alkali, no bleaching agent, no fluorescent agent, no water, no tree cutting). Good physical strength (tear resistance, folding resistance, frost resistance). The price is relatively cheap, the recycling process is easy, and there is no waste water or waste gas.

It can naturally decompose and return to the land after long-term exposure to sunlight for about six months, and it is easier to recycle. Waterproof, moisture-proof, oil-proof, anti-fouling, insect-proof, non-yellowing, non-discoloring, non-toxic. The use of lithium in a special matt place does not cause eyesight burden and does not harm the eyes.

In addition, stone paper is also called eco-friendly paper. It is made of powdered stone as the main raw material, plus polyethylene and glue. This kind of paper is waterproof, strong and not easy to burn. The most important thing is that it does not need to cut trees to make paper. It is very environmentally friendly and has a wide range of applications.

What are the advantages of stone paper itself?

1. Stone paper can be moisture-proof, waterproof, tensile, tear and folding resistance is also stronger than ordinary paper, especially suitable for use in humid environments;

2. The stone paper has no plant fiber, the surface is smooth and flat, it is not easy to faint when writing, and it saves ink when printing;

3. The stone paper is mainly a powder structure, which can be automatically weathered in 3 to 6 months in an environment exposed to the wild. If it is burned, it will burn easily without producing black smoke;

4. There is no need for bleaching in the production of stone paper, and there is no risk of heavy metal residues, fluorescent agents, etc., which is relatively safe;

5. Stone-paper products can be recycled again. At present, Shandong manufacturers support recycling and truly integrate production to recycling. It is precisely because of these advantages that stone paper has been used in news publishing, packaging, advertising, cultural paper, maps, and decorative wallpapers since its inception.

Compared with traditional papermaking technology, stone paper production does not need to consume wood, and the process and steps are relatively simple. Traditional papermaking technology has led to the consumption of a large amount of wood and excessive logging of forests. In 2016, two-thirds of China's industrial wood was used for papermaking, and the lack of wood supply has also become a major bottleneck for the development of the paper industry.

Stone paper uses the earth's abundant limestone resources as raw materials, which is an important way to alleviate the lack of wood. The large amount of "three wastes" emissions and large environmental pollution are also a major criticism of traditional papermaking technology. The production of stone paper does not require water or bleaching.

Therefore, there is no discharge of waste water, and it is more environmentally friendly than traditional papermaking. Moreover, only electric energy is consumed in production, and the energy consumption is greatly reduced. The unit energy consumption is only 2/3 of the traditional papermaking process. We provide stone paper products. If you are interested in stone paper products, please contact us for more information.

Synthetic paper is called "unbreakable" paper. At present, it is popularly called "stone paper". Stone paper uses inorganic powder (mainly calcium carbonate) as the main raw material, adds a small amount of synthetic resin and plastic additives, and adopts advanced technology to produce a new type of environmentally friendly synthetic paper. It is widely used in printing, packaging, cardboard and various Labels, etc., have excellent paper characteristics and environmental performance, which is a major technological change in paper production.

Stone paper is a new type of material between paper and plastic, and stone paper is a new type of environmentally friendly paper.

Stone paper is a new type of environmentally friendly paper. Its appearance is the same as traditional wood pulp paper, but its production method is different from that of wood pulp paper. It is made by adding calcium carbonate powder with 15% polyethylene and 5% adhesive after special processing. The use of dilute hydrochloric acid can distinguish stone paper and wood pulp paper.

The production process is simple; the investment is large, the output is high, and the energy consumption is low; it does not use plant fibers and does not cut trees, which can save a lot of wood and protect the natural ecology; it does not need to add strong acids, alkalis, bleaching agents and other chemical raw materials, and does not discharge waste water , Waste residue and toxic and harmful gases are green environmental protection products. The product has good mechanical properties, water resistance, moisture resistance, moth resistance, folding resistance, tear resistance, oil resistance, non-toxic, odorless, non-polluting, stable geometric dimensions, high printing definition, good effects, and can be naturally degraded into powder after being discarded. Nature and other characteristics.

The cost of stone paper products is 20%-30% lower than that of alternative products. It is extremely competitive and has a very promising market prospect.

The special matt lithium is used, which does not cause eyesight burden and does not harm the eyes. Stone paper products have a wide range of applications and can be used in disposable life consumables, such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, and foot covers Gloves, tablecloths, raincoats, dust covers, etc.; can also be applied to cultural papers, such as printing paper, writing paper, advertising decoration paper, road forest paper, coated paper, film paper, drawing paper, poster stickers, typing paper, Postal envelope paper, cigarette paper, glassine paper, newsprint, etc.; can also be used in building materials decoration, such as decorative wallpaper, etc.;

It can also be used in industrial packaging and other fields, such as fertilizer bags, cement bags, rice flour bags, clothing bags, various handbags, cartons and cartons, etc.; it can also be used in special papers, such as paper for field operations, and underwater operations. Paper, paper for mining operations, special paper for military use, etc. It can be said that the application field is very wide, and with the continuous maturity and upgrading of stone papermaking technology, the application field will be even larger.

The main advantages of environmentally friendly stone paper are as follows:

1. Environmental protection materials, energy-saving technology, no pollution (no strong acid, no alkali, no bleaching agent, no fluorescent agent, no water, no tree cutting).

2. Good physical strength (tear resistance, folding resistance, frost resistance).

3. The price is relatively cheap, the recycling process is easy, and no waste water or waste gas is generated.

4. It can decompose naturally and return to the land after long-term exposure to sunlight for about six months, and it is easier to recycle and reproduce.

5. Waterproof, moisture-proof, oil-proof, pollution-proof, insect-proof, non-yellowing, discoloring, non-toxic.

Someone flushed the memo paper made of stone paper under the faucet and found that the stone paper was not soaked or leaked. It didn't take long to wipe the water off the paper with a rag, and the paper was basically restored to its original condition.

This paper does not contain plant fibers, so it is much better in water resistance. The paper bag made of stone paper feels heavier and cooler. Unlike ordinary paper bags, it is very strong. They once tried to pour water into a handbag made of stone paper, and the result was that the handbag filled with 20 kilograms of water was intact and there was no leakage.

According to reports, the traditional papermaking process requires cutting down a large amount of wood as raw materials. And this kind of stone paper mainly extracts calcium carbonate from limestone, then uses polymer as the base material, utilizes the interface chemistry principle of polymer and the characteristics of polymer modification, and after special processing, the polymer is extruded. Manufactured by extrusion and blow molding process.

The production of stone paper does not first need to cut wood. In addition, there is no need to add a large amount of strong acids, alkalis, bleaches and other chemicals in the production process, and no waste water, waste residue, toxic and harmful gases and substances are discharged. The paper industry is the most polluting industry in China. If stone paper can replace traditional paper to a certain extent, its economic and ecological benefits, especially for energy conservation and emission reduction, will be quite significant.

According to legend, there was a county magistrate named Xu Xun in Jingyang County of the Jin Dynasty. He was brilliant in spells and was called Xu Zhenjun. One year, due to poor harvests, farmers could not pay taxes. Xu Xun asked everyone to pick up stones and cast spells. With a wave of his finger, the stones immediately turned into gold, and the people were able to deduct the tax owed. Since then, people have hoped that they also have a "golden finger" that can turn stones into gold. It is true that turning stones into gold is just a beautiful legend, turning stones into paper has become a fact. Let's talk about how the stone becomes "stone paper".

Stone paper, as the name suggests, is paper made of stone. Of course, this is a popular understanding. In fact, stone paper is made of inorganic powders such as calcium carbonate as the main raw material, with food grade pp or food grade pe and additives as auxiliary materials. A new type of paper product produced by special processes such as film.

It can be seen that stone paper is completely different from paper made with cotton, linen, wood and other plant fibers in the traditional sense. Since Cai Lun in the Eastern Han Dynasty invented papermaking, plant fiber paper has dominated the world for thousands of years. Until the 1950s, DuPont and other companies in the United States began to develop paper based on organic resins instead of plant fibers, called synthetic paper. It is called chemical film paper, plastic paper and so on. Japan, out of concerns about insufficient wood sources and reducing organic resin inventories, also increased the development of synthetic paper and took the lead in commercial production in the 1970s. Synthetic paper was also developed in our country in the 1970s. At that time, it was called "calcium plastic paper", but it was not used on a large scale. At the end of the 20th century, Taiwanese enterprises in my country developed stone paper with a calcium carbonate content of 60% and realized commercial production. China has only begun to develop and introduce stone paper production technology in the past ten years.

The main ingredients of stone paper are stone powder, added resin, etc. It is reported that there are three main production processes for environmentally friendly paper such as stone paper.

The first is the calendering method. That is, through batching, mixing, modification, extrusion, and calendering. The disadvantage of the calendering process is that it is complex. It is generally used to produce environmentally friendly paper products above 0.1mm. The product has a large proportion and the equipment is expensive, but the surface of the product is smooth. It is suitable for printing advanced samples and book covers.

The second is the casting method. By replacing the calender with a casting machine, it is possible to produce environmentally friendly paper of various thicknesses. However, the distribution of molecular chains in environmentally friendly paper is unidirectional, so the longitudinal, horizontal, and physical properties of environmentally friendly paper products are quite different. This is a major disadvantage of cast environmentally friendly paper.

The second is the biaxial stretching method. During the biaxial stretching process, some small gaps are formed between the base plastic and the filler, thereby reducing the proportion and cost of environmentally friendly paper. Because these small gaps have a pearly effect on light refraction, the environmentally friendly paper produced has a good appearance and has been widely used in packaging, printing, advertising and other fields.

The process flow of stone paper mainly adopts the combination of calendering and casting, and the organic base material basically adopts polyethylene-PE. The combination of calendering and casting is used to replace the traditional paper process, which is more suitable for the processing of polyethylene, the product performance has been improved, and the product production range is wider. The use of improved special equipment to complete the production of this type of paper can simplify the production process of stone paper, more stable quality, and more convenient operation.

Stone paper also has its own unique advantages in use and printing. Its main characteristics are not only waterproof, anti-fog, oil, insect, etc., but also tear and folding resistance. Stone paper absorbs ink firmly, and inkjet printing is not easy to be eroded. And because it is fiber-free, the clarity after inkjet printing is higher, and the surface is not covered with a film, it will not chemically interact with the ink, resulting in color cast and decolorization.

In daily life, stone paper has a wide range of uses. It can not only replace traditional charcoal paper, but also has good water resistance, good foldability and easy binding. It can replace opaque PVE, PE and other plastic films, which reduces the cost, and is suitable for packaging bags and other disposable products.

The application fields of stone paper products are extremely wide, and can be used in the following industries.

One-time life consumables. Such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc.

Cultural paper. Such as printing paper, writing paper, advertising decoration paper, Dowling paper, coated paper, film paper, drawing paper, poster stickers, typing paper, mailing paper, cigarette paper, glassine paper, newsprint, etc.

Building materials decoration and industrial packaging. Such as decorative wallpaper. In the field of industrial packaging, it can be used in fertilizer bags, cement bags, rice noodle bags, clothing bags, various handbags, cartons and cartons, etc.; it can also be used in special papers, such as paper for field operations, paper for underwater operations, Paper for underground operations, special military paper, etc.

Stone paper is a very environmentally friendly product, which can protect resources and save energy. The stone paper comes from mines and does not need to be cut down. It is a great protection for the forest. The production process of stone paper mainly uses calcium carbonate as the main raw material. The whole production process does not need to add a drop of water, which saves precious water resources. At the same time, the energy consumption is lower than that of traditional wood pulp papermaking, which helps to improve the problems of global warming caused by carbon dioxide.

Reduce pollution emissions. The production of stone paper does not require washing with water at all, nor does it require strong acids, alkalis and bleaching agents, so there is no waste water discharge problem and no water pollution. Recycling and degradation. After the stone paper is used, it can be recycled through plastic products. After collection, it can be crushed and squeezed to reproduce colored plastic bags, flower pots, and plastic buckets.

If it is treated as garbage and sent to an incinerator to burn, it will not produce poisonous gas. Because stone paper contains a large amount of stone powder and a small amount of non-toxic resin, when the resin burns, the stone powder will pulverize, promote the contact of the resin with air, and accelerate the complete combustion of the resin, so it will not produce black smoke due to lack of oxygen smoldering during combustion. After the non-toxic resin is burned, there is no toxic waste gas, and the emission of carbon dioxide is small.

Stone paper is based on limestone mineral resources with large reserves and wide distribution as the main raw material (calcium carbonate content is 70-80%), with high polymer as auxiliary material (content is 20-30%), using polymer interface chemistry and polymerization The characteristic of the material modification is that it is processed through a special process, and then made through polymer extrusion and blow molding processes.

Stone is a new type of material between paper and plastic. It can not only replace some traditional functional paper and professional paper, but also replace most traditional plastic packaging. And it has the characteristics of low cost and controllable degradation, which can save a lot of cost for users without causing pollution. From the perspective of replacing traditional paper parts, it can save a lot of forest resources for the society and reduce the secondary pollution generated in the papermaking process; from the perspective of replacing traditional plastic packaging parts, it can save a lot of strategic resources for the country. (Each ton used can save 2.3 tons of fuel), the product can be degraded after use, and will not cause secondary white pollution. Environmental protection new materials The stone paper industry has a wide range of materials, and the space for product upgrades, technology upgrades, and application areas is very broad. It is a sunrise industry with strong vitality.

Stone paper can protect resources and save energy. The stone paper comes from the mine and does not need to be felled. This is a great protection of the forest. The production process of stone paper mainly uses calcium carbonate as the main raw material. There is no need to add a drop of water throughout the production process, saving precious water resources. At the same time, energy consumption is lower than that of traditional wood pulp papermaking, which helps to improve global warming caused by carbon dioxide. Reduce pollution emissions. The production of stone paper does not require washing with water, strong acids, strong alkalis, and bleaching agents. Therefore, there is no wastewater discharge problem, and no water resources are polluted. Recycling and degradation. After the stone paper is used up, it can be recycled through plastic products. After collection, it can be crushed and squeezed to reproduce colorful plastic bags, flower pots and plastic buckets.

Good scope of application. Through the application of a variety of new technologies, stone paper products have many new characteristics that ordinary paper does not have: such as high strength, anti-fog, oil-proof, insect-proof, long elongation, moisture resistance, corrosion resistance, tear resistance, and folding resistance And so on, so it has a wider range of uses than ordinary paper. The various packaging bags, feed bags, cement bags, clothing bags, raincoats, tablecloths, wallpaper, special paper products, etc. made by it have multiple characteristics such as low price, high load-bearing, waterproof, dustproof, and mothproof. The comprehensive advantages of this kind of packaging. Therefore, the scope of its application theoretically, stone paper seems to be able to replace most of the traditional paper, including cultural paper, industrial paper, packaging paper, information paper and special paper. For example, it is used to print beautiful wall calendars, posters, book covers, illustrations, art books, picture albums, children's books, various exquisitely decorated packaging, paper handbags, labels, trademarks, etc.; and high-end printing for exquisite printing Posters, maps, notebooks, product manuals, textbooks, magazines, etc. In addition, there are special papers such as paper for underwater operations, paper for field operations, paper for underground operations, and paper for military field operations.

Has a huge raw material cost advantage. Traditional papermaking consumes a lot of wood, while stone paper uses calcium carbonate, the most abundant mineral resource in the earth’s crust, as its main raw material. Calcium carbonate is mainly derived from calcite, marble, limestone and other ores, which are extremely abundant in storage in China, and the price is comparable. Cheap, the cost of its ultrafine powder is less than 1/10 of the cost of wood pulp fiber; while the resin polymer material derived from petroleum accounts for only about 25%. When the price of petroleum is not very high (such as the price of crude oil 100 US dollars per barrel), the overall cost of stone paper is significantly lower than that of plant fiber paper. Without including the production cost, the raw material cost of wood pulp fiber paper is about 25% higher than that of stone.

It has obvious environmental advantages and environmental costs. The entire production process of stone papermaking does not need water, does not need to add a large amount of strong acid, strong alkali, bleaching powder and many organic chlorides, and saves several important pollution links such as cooking, washing, bleaching and drying compared with the traditional papermaking process.

Good physical properties: stone paper not only has the same whiteness and opacity as traditional paper, but also has many properties that traditional paper does not have, such as waterproof, moisture-proof, mothproof, chemical resistance, and high printing clarity , Good mechanical properties, flattening performance, surface smoothness and degradability and other characteristics.

Good safety performance: The main body of the stone paper is calcium carbonate and other inorganic substances. The resin and various additives are also non-toxic and have no adverse effects on the objects in contact. At the same time, stone paper does not absorb water, and it is difficult for molds to adhere to the surface of the paper, and the disposal of waste paper is also very safe and will not cause soil pollution. Good printing and writing performance: stone paper can be printed with ordinary inks, flexographic, gravure, offset, silk screen and other printing methods can also be used for printing, and pencils and ballpoint pens can also be used for direct writing. The photo paper is made by coating ultra-fine calcium carbonate powder on a resin substrate. These ultra-fine particles make the surface of the paper have numerous small holes, which facilitates the firm absorption of ink and avoids the phenomenon of ink halo.

Because the stone paper has no fibers and is smooth and smooth, it has high definition after inkjet printing. The calcium carbonate on the surface of the photographic paper will not chemically react with the ink, and the occurrence of color cast and decolorization is avoided. Traditional color inkjet printing paper is prone to smudging ink on the surface, and the ink layer even oozes to the back. Stone paper does not have this disadvantage. Under the requirements of the same definition, the calcium carbonate particles and resin molecules in the stone paper hardly penetrate the ink compared with the plant fiber, so it will save about half of the ink volume and greatly reduce the printing cost. Stone paper will not be oxidized by air, will not change color or become yellow, and is more suitable for the preservation of precious photos. Compared with traditional color inkjet printing photo paper, the price of stone paper photo paper is only about 1/3 of the latter, which will significantly reduce the cost of photo paper users.

Stone paper is also called environmentally friendly paper. It uses calcium carbonate, the most abundant mineral resource in the earth’s crust, as its main raw material. It uses polymer materials and a variety of inorganic substances as auxiliary raw materials. It uses polymer interface chemistry and filling modification technology. A new type of recyclable paper with modern technical characteristics. At the 2010 National “Two Sessions”, the meeting notices, schedules, sticky notes and other materials used by the delegates and members of the meeting were all stone paper. This technology is not new, but in the context of the global call for energy saving and emission reduction, this "fashionable" environmental protection concept has been valued again by people.

Stone paper has many advantages:

1. Energy saving and environmental protection of production technology

According to statistics, traditional papermaking technology uses 3.7 tons of wood chips to produce 1 ton of paper, which is equivalent to cutting 20 large trees with a growth period of 20-40 years. At the same time, it uses 200 tons of fresh water, consumes 1.8 tons of standard coal, and consumes 600 kilowatts of electricity. At the same time, a large amount of waste water and more than 300 types of hazardous waste gas have been identified. The stone paper breaks through the papermaking technology that has been used for more than 2000 years with wood pulp and straw pulp as raw materials. The production technology is energy-saving and environmentally friendly. The production process does not require water, acid and alkali, bleaching, and no waste gas, waste water or other harmful waste. The unit energy consumption is only 2/3 of the traditional papermaking technology.

2. Superior performance

(1) Superior physical properties. The physical properties of stone paper, such as tensile strength, tearing resistance, bursting resistance and folding resistance, are larger than those of plant fiber paper. The surface is not easy to fluff, it is durable and has stable dimensions.
　　
(2) Outstanding chemical performance. Stone paper has good antibacterial and insect resistance, outstanding water resistance, oil resistance and chemical resistance, and is not easy to change color.

(3) Good safety performance. The main raw material of stone paper is calcium carbonate and other inorganic substances. The resin and various additives are also non-toxic and have no adverse effects on the objects in contact. At the same time, stone paper does not absorb water, and it is difficult for molds to adhere to the surface of the paper, and the disposal of waste paper is also safe and will not cause soil pollution.

(4) Good printability. ①Stone paper is to coat nano-scale stone powder slurry mixed with a small amount of auxiliary materials on the substrate. After molding, many tiny particles make the surface of the paper have countless small holes, which promotes the adhesion of pigments more firmly, and is used in various types of inkjet printers. It will not be corroded during the printing process, and it is well waterproof and oil-proof. ②Because stone paper is not made of wood fiber, the paper surface is flat and smooth, and there is no ink halo phenomenon. Therefore, compared with traditional plant fiber paper, stone paper saves more ink or pigment in printing under the same conditions, and has higher definition. ③The calcium carbonate on the surface of the stone paper will not chemically react with the ink, which avoids the occurrence of color cast and decolorization of the printed product.

It can be seen that the emergence of stone paper not only guarantees high-definition, high-precision printing quality, but also brings about the "devaluation" of the printing accuracy of traditional plant fiber paper. In addition, because most pigments contain a large amount of heavy metals and toxic organics, the reduction of printing pigments not only saves resources and reduces costs, but also reduces environmental pollution caused by the production, use, recycling and processing of printed materials.

3. Wide range of uses

Stone paper has a wide range of applications due to its excellent performance. Excellent water resistance makes it especially suitable for outdoor advertising. Because it does not produce dust and does not shed hair, it can be used in clean rooms. Table 2 shows the scope of application of stone paper.

The types of bags we use in daily life include plastic bags, cloth bags, paper bags, etc., and the manifestations of plastic bags are also ever-changing. However, with the increasing pressure of white pollution on the environment, the failure to provide plastic bags has corresponding inconvenience to our daily shopping. The production of environmentally friendly bags has attracted attention!
The new material PCC high-energy masterbatch made by Shenzhen Shineng Paper Co., Ltd. through technical processing and refining of a stone can not only produce products that replace plastics, but is basically the same as petroleum-based plastic products in appearance. While being environmentally friendly, it greatly reduces the production costs of plastic products companies. The environmental protection bag-Stone Paper Bags produced by PCC high-energy masterbatch has been promoted in many large supermarkets.

The PCC high-energy masterbatch developed from this kind of stone can be directly degraded by thermal oxygen, and directly turned into calcium carbonate after incineration. It can also be decomposed naturally under natural light conditions. Unlike plastic products, it is difficult to be naturally degraded. It is burned. Sometimes it will pollute the atmosphere and leave coking.

Traditional paper is made of plant fibers, which may damage the environment. At present, some manufacturers are introducing paper made of stone. This paper is waterproof, durable, and more environmentally friendly. It does not require trees, does not require bleach in the production process, and uses less water.
Waterproof stone paper is made of about 80% calcium carbonate. Calcium carbonate is the main component of limestone and marble. The paper company crushes the rocks left over from the construction and quarries, then uses plastic to fuse the powder together, and then uses a roller to It is squashed until it is as thin as paper. Since this paper is made of fine particles instead of coarser plant fibers, it feels smoother than traditional paper.

The stone paper notebook is nothing special from the appearance, and looks similar to an ordinary notebook. The seemingly plain paper actually hides mystery. This is a material called stone paper, which has a stronger texture, and has a certain degree of ductility when it is pulled up, and it will not tear directly.
What is stone paper? This is a new type of material between paper and plastic. It uses calcium carbonate as the main raw material, and is supplemented by high molecular polymers and various inorganic substances, and then uses the principle of high molecular interface chemistry and filling Modification technology, finally processed by special technology. In addition to its very tough texture, it also has water-repellent properties and will not deform easily when soaked in water.
Thanks to the characteristics of stone paper, coupled with a water-soluble pen, it can be repeatedly written and erased, and it feels like you will never finish writing. Write some text at random, wipe it lightly with a wet wipe or a damp cloth, and the word will be gone. As long as the writing is not done with great force, it will basically leave no trace.
If you want to clear the entire book together, and are too lazy to wipe it page by page, just put it in the microwave and you'll be done, but you have to put a glass of water underneath.

The hair dryer can also erase handwriting.

Saving paper to protect forests, I believe everyone is familiar with such words. The environmental hazards of cutting wood and making paper cannot be ignored, but the use of paper is inseparable in life, so the replacement of traditional paper is very important.
Stone paper is a new type of material between paper and plastic. It can not only replace part of the traditional functional paper, professional paper, but also replace most of the traditional plastic packaging. Environmentally friendly paper with limestone and coal gangue powder as the main raw materials.

Advantages of eco-friendly stone paper
1. Obviously, very environmentally friendly.
Stone paper is made of abundant calcium carbonate resources. The production technology is energy-saving and environmentally friendly. The production process does not require water, does not produce waste gas, waste water, waste residue, etc. The product is degradable and has low energy consumption.
2. Superior performance, environmental protection alone is not in line with business, so superior performance is also an important point.
(1) Superior physical properties. Stone paper has strong tensile strength, tear resistance, burst resistance and folding resistance, and is durable and dimensionally stable.
(2) Outstanding chemical performance. It has good antibacterial and insect resistance, outstanding water and oil resistance, and is not easy to change color.
(3) Good safety performance. The stone paper has no adverse effect on the objects in contact. The disposal of its waste paper is also very safe and will not cause soil pollution.
(4) Good printability. The paper surface is flat and smooth, there is no halo phenomenon, it saves more ink than the traditional low-sheet, and has higher definition, which can avoid the occurrence of color cast and discoloration of printed products.
3. The cost of stone paper is lower. The cost of inorganic powder and environmentally friendly stone per ton is about 30-40% lower than that of plastic bags, and 20% lower than the cost of some high-grade wood pulp paper.

Of course we cannot ignore the shortcomings of stone paper
(1) The papermaking process of stone paper has strict environmental requirements, and the production workshop is required to be clean and dust-free, otherwise its performance will be affected.
(2) The inherent deficiencies of stone paper, such as thermal deformation, non-absorption, etc., determine that stone paper cannot be used as carbonless copy paper, laser printing, bond paper, etc. The life span is generally 20 to 30 years and cannot be stored for a long time.
(3) Stone paper is heavier than traditional paper, which brings inconvenience to binding and transportation.
(4) At present, it is difficult for the thickness of stone paper to reach a thinner level, and the product specifications are not complete, only limited to the conventional small format below A1.

The reason for choosing stone paper is the performance of sustainable development, and striving for the goal of research and promotion of conservation and environmental friendliness is a better choice for environmental protection.

Eco-friendly paper is a kind of paper produced from waste paper through more than a dozen processes such as sorting, purification, pulping, papermaking, etc. It does not affect the normal use of office and study, and is beneficial to protect the health of eyesight. Today, when the world is increasingly advocating environmental protection thinking, the use of eco-friendly paper is a popular move.

Eco-friendly paper is paper produced from waste paper as raw material, crushed, decolorized and pulped through various processes. 80% of its raw materials come from recycled waste paper, so it is known as environmentally friendly paper with low energy consumption and light pollution. There are many kinds of urban waste paper, and different types of waste paper are used as raw materials to make different recycled copy paper and recycled packaging paper. Generally, it can be divided into two categories: one is low-grade paper such as hanging panel paper and toilet paper; the other is paper for books, newspapers, magazines, copy paper, printing paper, postcards, and exercise books.

Eco-friendly paper is not equal to eco-friendly paper. Paper produced from wood pulp and straw pulp is also called eco-friendly paper. Eco-friendly paper is the collective name of the market! Eco-friendly paper is produced using waste paper as raw materials and does not add any brighteners, fluorescent agents and other chemical agents, so the color of eco-friendly paper is yellowish natural color! The difference between eco-friendly paper and eco-friendly paper is the difference in raw materials.

Eco-friendly paper does not add any brighteners, fluorescent agents and other chemicals, so it shows the beauty of the paper's natural color, slightly yellowish paper; because it is not reflective, it is actually more conducive to protecting our eyes. Europe and Japan More than ten years ago, eco-friendly paper has been regularly used as office and study paper.

The eco-friendly paper claimed by many companies on the market does not actually belong to eco-friendly paper; the EU international standard is only eco-friendly paper, and eco-friendly paper is just a general term. The biggest difference between eco-friendly paper and eco-friendly paper is the raw material. The difference is that eco-friendly paper uses waste paper as a raw material, while eco-friendly paper uses wood pulp as a raw material.

As the name suggests, waterproof stone paper is paper produced from stones. Stones produce paper? However, not all stones can produce paper. The waterproof stone paper produced is a kind of limestone.

Everyone must think like me that paper is produced from wood pulp and straw pulp. Do you know that with the continuous development of science and technology, the continuous improvement of technology, the upgrading of technology, the continuous attempts of researchers finally found this kind of production waterproof stone The raw material of paper is limestone. The production of waterproof stone paper does not need to use wood pulp and water, no need to strengthen acid, no need to add bleaching agent, no need to strengthen alkali and other chemicals, only need to use raw material limestone plus a small amount of polymer materials and electricity. Energy saving and environmental protection have fundamentally solved the problem of environmental damage.

Can the paper produced by waterproof stone paper completely replace the paper produced by the original technology? The manufacturer tells you that not only can stone be completely replaced, but there are also many advantages that the original production technology of paper does not have, such as: waterproof, ordinary paper cannot be waterproof, basically it will become a ball when it touches water. , And waterproof stone paper has good waterproof performance, the effect of ordinary paper printing is relatively fuzzy, and waterproof stone paper has good ink absorption, the printing is very clear, and the folding performance is good, easy to bind and so on.
 
The application field of waterproof stone paper is very wide, such as disposable daily consumables, school stationery, packaging supplies, daily necessities, and paper for special industries, etc. The manufacturers will not give examples one by one. You must be curious. The production process of waterproof stone paper should produce waste. Does this waste have any impact on our living environment? The manufacturer tells you that, in fact, the waste generated in the production of waterproof stone paper can be recycled. This limestone can be reused to produce paper. There is no waste at all. If you don’t want to use it, you can also make plastic and recycle it as PE. Good materials for plastic processing are not very environmentally friendly, whether it is raw materials or processed waste materials, has no impact on our environment.

Color masterbatch is just a general term. It is also divided into many types of functional products, each with different functions, so the requirements for pigments are also different. Today we will take a look at different types of functional masterbatches. Choose paint:

　　 (1) The pigments used in heat-resistant products are basically required to withstand the temperature during the production of polypropylene fibers and maintain their performance stability. The temperature resistance is generally required to be above 270~280℃.

　　(2) The pigment for dispersible masterbatch should have good dispersibility and be evenly dispersed in the product, and the dispersant used should not reduce the quality of polypropylene fiber. Otherwise, it is impossible to produce high-quality dope-colored fibers, and the operation is also unstable, and it is easy to break or produce abnormal fibers when the fibers are drawn.

　　(3) There are many applications for the coloring of lustrous polypropylene stock solution. Among them, it is used for bed cover base fabrics and knitted fabrics, which require bright colors. Because organic pigments are brighter and brighter, and easy to color, organic pigments should be used for the above purposes.

(4) Light resistance. Some pigments have photosensitivity under the action of light, which can make colored fibers fade and brittle. The light resistance of pigments is basically related to their chemical structure, so pay attention to the light resistance of pigments when making masterbatches. When light-fast pigments need to be used, you can consider adding ultraviolet absorbers.

　　 (5) The pigments used in stability products must have excellent stability against the black masterbatch polypropylene fiber. It means that the pigment will not react with the fiber when the colored fiber polymer is exposed to heat, light or high temperature for a long time, and new chemical groups are formed to make the polymer performance low.

The right pigment of the masterbatch can be selected to ensure the effect of the finished product. If the wrong pigment is selected, various problems may occur during the production process, resulting in a large difference between the produced product and the expected, so the gain is not worth the loss. .

　Masterbatch is a special coloring product, mainly used in PP plastic modification and plastic products with PP as carrier. Because plastic products have high requirements for gloss, we must find ways to improve its gloss during use:

　　1. If you use PP as a carrier, you can add 3% EBS to improve the gloss effect is very obvious, you must add 0.5% CaSt and ZnSt to stabilize the molecular structure of PP during the molding process;

　　2. If the masterbatch is used in injection molding products, 2% TiO2 or brightener can be added;

　　3. If used in blow molding and blown film, the simpler the formula, the better, but the amount of dispersant should be increased to make it fully dispersed;

　　4. Pay attention to the small granular shape of the mixing material to increase the output and avoid the negative material at the feeding port.

　　 In addition to adding some additives in the application of color masterbatch, we can also improve its gloss by reducing the dilution ratio and reducing the water content of the product during the operation to meet the gloss requirements of plastic products.

Stone paper is a new environmentally friendly material whose texture lies between paper and plastic. Stone paper is more environmentally friendly because it has lower production costs and is much more waterproof and anti-corrosive than ordinary paper, and because it does not require wood in the production process. Therefore, stone paper has been favored by consumers. Stone paper can also be used in many industries, and it can be said to be very versatile. Let's talk about the use of stone paper.  

1.Printing and packaging
The application fields of stone paper products are extremely wide, and they can be used in disposable daily consumables, such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc.

2.Used to make stationery
Stone paper can also be used in cultural paper, such as printing paper, writing paper, advertising decoration paper, road forest paper, coated paper, film paper, drawing paper, poster stickers, typing paper, postal envelope paper, cigarette paper, glassine Paper, newsprint, etc.

3.Used as building materials
When making decorative stone paper for building materials, calendering and casting stone papers are mostly used to make embossed wallpaper, imitation leather paper, wood-grain paper, and stone-grained paper covering plastic.
                        

With the development of society and technology, people have begun to pay more attention to environmental protection issues, and they have begun to research and produce some environmental protection materials. Stone paper is an new environmental protection material born in this process.
                                                                          
As an environmental protection material, stone paper has many advantages that ordinary paper does not. 

1.Stone paper does not need water in the entire production process, does not need to add strong acids, strong alkalis, bleaching powder and many organic chlorides. Compared with traditional papermaking processes, it eliminates several important pollution links such as cooking, washing and bleaching.

2.Stone paper uses low-priced ore powder as the main raw material, and the cost is 20%-30% lower than traditional paper, and the price is also 10%-20% lower. The paper made of stone looks nothing special, but the written words are soaked in water, taken out after ten minutes, and wiped with your hands. Not only will the words not faint, you can still write on the water. Stone paper is very durable and can save companies a lot of costs.

3.Stone paper is not only waterproof, anti-fog, oil-proof, insect-proof, etc., but also superior to wood pulp paper in terms of physical properties, tear resistance and folding resistance.

Why stone paper products environmentally friendly

Stone paper products making is particularly prominent in environmental protection. Compared with the traditional papermaking process, the production process does not produce waste water, waste gas, waste residue, and it is a non-polluting green environmental protection project.

In terms of water use, each ton of traditional paper production consumes 100 tons of fresh water, and the entire production of stone paper production process does not require water.

In terms of raw materials, the main raw material of traditional papermaking is forest resources, and the main raw material of the production process of stone paper is coal gangue, slag and other stone materials, which does not consume forest resources.

Handling of stone paper products

Traditional fiber paper can be recycled into recycled paper after being used up to achieve resource reuse. Thermoformed stone paper can also be recycled and reused. After recycling, it can produce darker-colored wrapping paper, and can also be made into various signs and flower pots.

The used stone paper is recycled or treated as garbage. When it is burned into an incinerator, only non-toxic resin can be burned. Stone powder can promote the contact between the resin and the air, accelerate the complete combustion, and will not produce black smoke due to the lack of oxygen and smoldering. There is no toxic exhaust gas after combustion, and the amount of carbon dioxide emitted is very small, which helps to slow down and improve the problems of global warming caused by carbon dioxide.

Even if it is discarded outdoors, the stone paper will automatically embrittle into broken eggshells after being exposed to sunlight for about 6 months, restore the earth and return to nature; buried in the ground for 1 year, it can degrade and become powder, and it will not cause environmental pollution.

Production of stone paper products

For ordinary paper, it may use a lot of water in the production process, but thermoforming stone paper uses almost no water, and the process is never bleached, so the biggest difference between us and ordinary paper is that the primary color of stone powder will affect the color of the paper. For example, coal gangue paper will be slightly black, depending on the purpose of the paper.

Stone heat sealable paper bags are ideal for food packaging, items such as spices, cheese slices, and thick pastes such as ketchup and mayonnaise. These bags provide moisture, oxygen and UV protection, have been tested to quality standards, and are made entirely of heat-sealable materials.

Custom stone heat sealable paper bags for food
Packaging in the food packaging industry requires custom printing of its sealed bags, as it is often necessary to provide consumers with specific instructions on how to enjoy food properly. In many countries/regions, especially on edible foods, the product description, ingredient weight, manufacturing, and expiration date are printed on each pouch, which is also required by law. Companies can print their sealed bags in the most attractive way by customizing all legal information required by law and the company’s name and logo.

Types of stone heat sealable paper bags
Standard flat heat-sealed bags: These are one of the most common types of bags used for food packaging. One or both sides of these bags are transparent, so you can put the contents in front of everyone to display.

Laminated heavy products: Made of stronger materials than standard materials, they are crimped and sealed on the bottom, with a central weld on the back.

Metalized flat bags: These are good choices for coffee powder, powdered spices, food supplements and other products. These bags protect against ultraviolet rays, moisture, and oxygen, and have ripping options at both ends of the bag.

For your company, the most feasible packaging bag depends on the type of product you plan to produce and package. Before finalizing the choice, three things need to be determined:
Bag type: How strong do you need to be? Do you only need packaging options or do you have to consider moisture resistance? You can choose transparent, laminated, transparent front solid back, metallized or composite stable bag.

Printing type: It depends to a large extent on your budget. You can perform monochrome, multicolor, full CMYK, matt, metal or holographic printing.

Seal type and shape: can include a tear at one of the two ends of the bag, a child-resistant sealed bag, a DOY bag, germination and hanging holes or handles.

Waterproof stone paper is particularly prominent in environmental protection. Compared with the traditional papermaking process, the production process does not produce waste water, waste gas, waste residue, and is a pollution-free green environmental protection project. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of production, while the stone paper production process requires no water for the entire production.

In terms of raw materials, the main raw material of traditional papermaking is forest resources, while the main raw material of stone paper production process is coal gangue, slag and other stones, which do not consume forest resources. Traditional fiber paper can be recycled into recycled paper after use up to realize resource reuse. Thermoformed stone paper can also be recycled and reused. After recycling, it can produce dark-colored packaging paper, can also be made into various signs, flower pots, etc., and the used stone paper is recycled or treated as garbage.

When incinerated, only non-toxic resin can be burned. Stone powder can promote the contact between resin and air, accelerate the complete combustion, and avoid black smoke caused by suffocation due to lack of oxygen. There is no toxic exhaust gas after combustion. Helps mitigate and improve global warming caused by carbon dioxide.

Even if discarded outdoors, the stone paper will automatically embrittle into a broken eggshell shape after being exposed to sunlight for about 6 months, reducing the earth and returning to nature; it can be degraded into a powder (inorganic mineral powder) after being buried in the ground for 1 year. Will cause environmental pollution. It can replace a part of traditional wood papermaking.

In general paper, it may use a lot of water in the process of making it, but thermoforming stone paper hardly uses water, and the process does not bleach. So the biggest difference between us and ordinary paper is that the original color of stone powder will affect the color of paper. For example, coal gangue paper will be slightly black, depending on the purpose of the paper.

This project is dedicated to the development and research of functional thermoformed stone paper packaging materials. Applying the idea of ​​integrated innovation, using stone paper as the raw material, combining the excellent properties of stone paper with the mechanical properties of honeycomb paperboard and corrugated paperboard, the development of stone paper composite corrugated paperboard and stone paper honeycomb paperboard with various functions and its Related production processes, and creatively introducing foaming technology into the production of stone paper, reducing the proportion and cost of stone paper materials.

Through the research and development of stone paper production technology and the exploration of performance characteristics, the application of stone paper materials in the packaging field is promoted. The core layer of the stone paper honeycomb paperboard is formed by a chain compression molding process, that is, the core layer is pressed by the core paperboard through a chain molding device with a protruding honeycomb hexagonal prism structure, and then the prepared core layer and the stone paper are pressed. Tissue paper is melt-bonded at an instant high temperature.

Compared with the traditional corrugated cardboard of the same specification, the stone paper composite corrugated cardboard with a thickness of 4.50mm has a break resistance of at least 2.5 times and a puncture strength of 1.7 times. The core layer of the stone paper corrugated cardboard adopts the extrusion flow calendering molding process, that is, the stone paper is directly extruded and cooled in a molten state through a corrugated die to obtain a core layer. Each bonding surface is pre-heated and bonded by instantaneous high-temperature hot-melt bonding. Compared with the conventional honeycomb paperboard of the same specification, the prepared honeycomb paperboard with a basis weight of 202g / m2 has a flattening strength of 2.6 times that of the traditional honeycomb paperboard, and the burst resistance is at least 2.5 times that.

Lightweight stone paper, which is a light weight multi-layer stone paper composed of foamed stone paper and non-foamed stone paper. Foaming and hot-melt compounding are the key technologies. Multi-channel extrusion is used. Machine, followed by hot press foaming. During the production process of lightweight stone paper, AC foaming agent with a weight percentage of 0.1 ~ 0.7% is selected for the foaming process, and the temperature of the multi-layer runner of the extruder is 160 ~ 170 degrees Celsius, and the hot-pressing foaming temperature is 180- 200 degrees Celsius

Stone paper is a new material between paper and plastic, which can not only replace some traditional functional paper and professional paper, but also replace most traditional plastic packaging. Paper to stone has the characteristics of low cost and controlled degradation, which can save a lot of costs for users without causing pollution. So, what kinds are there?

1.Degradable environmentally friendly packaging materials.

The product has no harmful properties such as heavy metals, no odor, moisture resistance, flame retardant and antibacterial. The environmental protection indicators of its products have not only passed the testing and certification of relevant national testing agencies, but also reached the European Union's testing standards. Major breakthroughs have been made in environmental protection.

3.Environmental protection stone paper products.
It is mainly used to replace some traditional cultural paper, packaging paper and special paper. This type of product changes the traditional papermaking process technology, does not use wood pulp, does not need to cut trees, does not emit strong acids and alkalis and other chemical substances, and does not discharge wastewater

Believe many people may not have discovered that stone paper has begun to enter our lives. It is possible that the handbags, lunch boxes, and packaging bags we use are made of stone paper, so how did the stone become soft? What about paper?

Stone heat seal paper is paper made from stone, which is called synthetic paper in the industry. The main material of the stone is calcium carbonate, which is processed by a special process using calcium carbonate as a raw material, polymer materials and various inorganic substances as auxiliary materials. The whole process requires no pulping, no water addition, no strong alkali, strong acid, bleaching agent, no waste water, waste gas, waste residue, especially energy saving and environmental protection. This is the embodiment of new paper technology with modern technical characteristics.

To make stone paper, the first step is to pulverize and grind the stone that is going to be used for papermaking with professional mill equipment, and mix 80% stone powder with 15% polyethylene and 5% additives. Using the principle of polymer interface chemistry and the characteristics of filling modification, the mixed materials are processed by mixing, extrusion, coating and other processes.

Stone powder, polyethylene and additives are made together with a principle similar to what we usually do at home and dough. Stone powder is equivalent to flour, polyethylene acts as water, and additives are equivalent to yeast. By using a granulator, the three mixed materials are pressed into dough and produced according to different needs. If a thin paper is needed, the material is blown into a thin paper. If the demand is thick paper, a die is used. Pressed into thick paper.

Stone heat seal paper cannot completely replace the traditional wood pulp and straw paper, but it can be partially replaced, about 60%. Stone papermaking can not only solve the environmental pollution caused by traditional papermaking, but also white pollution caused by a large number of plastic packaging materials. Therefore, this papermaking technology has great economic value and social significance.

Features: simple production process; large investment, high output, low energy consumption; no plant fiber, no tree felling, can save a lot of wood, protect natural ecology; no need to add chemical materials such as strong acid, strong alkali, bleaching agent; no discharge of waste water, waste residue and toxic and harmful gases are green products.

The stone heat seal paper has good mechanical properties, waterproof, moisture-proof, moth-proof, fold-resistant, tear-resistant, oil-resistant, non-toxic, odorless, non-polluting, stable geometric size, high printing clarity, good effect, and can be naturally degraded into powder after disposal Features such as nature.

Thermoformed large wrapping paper, also known as thermoformed calcium carbonate cardboard, is mainly composed of calcium carbonate.

In the production process of stone board, calcium carbonate is mainly used as the main raw material. The entire production process does not need to add a drop of water or consume wood, which saves precious water resources and forest resources.

Using stone to make products, the current technical problem to be solved is how to provide a low-cost, high-performance stone cardboard. In order to solve this technical problem, the technical solution adopted is to produce a three-layer composite structure of stone cardboard, including an upper surface layer, a lower layer and an intermediate layer. The so-called upper surface layer, lower surface layer and middle layer are all large wrapping paper layers.

The thickness of the above-mentioned stone cardboard is 0.3 to 2.5 mm, and the thickness ratio of the surface layer to the intermediate layer is 1: 2.5 to 1: 4.5. The upper and lower layers are stone paper layers with low stone powder content, and the middle layer is stone paper layers with high stone powder content.

Folders / file boxes currently on the market, including their skins, are also made of stone cardboard. This new type of stone cardboard has a three-layer composite structure, with an upper surface layer, a lower surface layer and an intermediate layer of the stone cardboard. Each layer can use stone paper layers with different stone powder content, and the middle layer can use stone paper layers with high stone powder content to reduce the cost of cardboard; the upper and lower layers can use stone paper layers with medium or low stone powder content. In order to improve the strength, toughness and surface finish of the product, the three-layer composite structure of stone cardboard can realize the unification of high performance and low cost of the product.

The so-called stone papermaking is to grind calcium carbonate, the main component of the stone, into ultra-fine particles, and then blow the paper with polyethylene and glue. In the context of global calls for energy conservation and emission reduction, this non-new stone paper has been labeled with the "fashion" label of low-carbon emission reduction and environmental protection, and has entered the public's vision.
However, as a paper-making product, stone paper has its unique functionality, but its technology needs to be improved, and there are still problems in recycling. Therefore, we should look at stone paper dialectically.
 

What is the difference between the early synthetic paper and the current stone paper?
The early synthetic paper had a calcium carbonate content of less than 60%, and it was necessary to use a large number of other added elements to synthesize. Now the content of calcium carbonate can reach 80%, and the high-quality calcium carbonate is not expensive per ton, which reduces the cost.
At present, synthetic paper is widely used in the packaging industry, but it is rarely used for publication printing. Because synthetic paper is more expensive than paper for newspapers and periodicals, it is rarely used in publications. However, because synthetic paper is waterproof and moisture-proof, customers use it to print maps and make notebooks.

 
Dialectical view of stone paper
1. Stone paper is waterproof and moisture-proof and has its functionality, but stone paper cannot replace traditional paper. As a product of the paper industry, stone paper has its existence rationality.
2. Stone paper book is just a new material. Stone paper and fiber paper have their own uses. Stone paper will not replace fiber paper.
3. Any product has its own advantages and disadvantages. We should use our strengths and avoid weaknesses when using it. Fiber paper produces pollution during the production process, but can be recycled after use to make paper pulp. Stone paper has no pollution during the papermaking process, but is generally incinerated or self-degraded after recycling, and the value of utilization is low.

The appearance of stone paper(stone notepad paper) is gradually being valued at home and abroad. Unlike traditional papermaking, the raw material of stone paper is mainly stone, a small amount of resin and some additives, which are made by a series of physical methods.

Characteristics of stone paper:
• Simple production process; large investment, high output and low energy consumption.
• By not using plant fiber or cutting trees, a large amount of wood can be saved and natural ecology can be protected.
• It does not need to add chemical materials such as strong acid, strong alkali, bleach, and does not discharge waste water, waste residue and toxic and harmful gases.
• The product has the characteristics of good mechanical properties, waterproof, moisture-proof, moth-proof, folding-resistant, tear-resistant, odorless, pollution-free, stable geometric dimensions, high printing clarity, and can be naturally degraded into powder and returned to nature after being discarded.

Classification of stone paper(stone notepad paper):
The first category: a series of degradable environmentally friendly packaging materials.
This product is mainly used to replace traditional plastic packaging products. There are two major series of industrial packaging materials and living packaging materials. Among them, industrial packaging materials include: dust covers and protective covers for electronics, home appliances and industrial equipment. Living packaging materials include various packaging bags, shopping bags, garbage bags and roll bags used in daily life.

The second category: environmentally friendly thermoformed stone cardboard products.
Due to advantages in raw materials, production technology, and technological processes, thermoformed stone cardboard products are the only boards in the world that are close to zero benzene and zero formaldehyde. The products have no harmful substances such as heavy metals, no odor, moisture resistance, and flame retardant. And antibacterial functions. The environmental indicators of its products have not only passed the testing and certification of relevant national testing agencies, but also reached the European Union's testing standards, and have made major breakthroughs in health and environmental protection!

The third category: environmental protection stone paper sheet products.
It is mainly used to replace some traditional use plates, packaging plates and special plates. This type of product changes the traditional board making technology, does not use wood pulp, does not need to cut down trees, does not emit strong acids, strong alkalis and other chemical substances, and does not discharge wastewater.

The appearance of stone paper is gradually being valued at home and abroad. Unlike traditional papermaking, the raw material of stone paper is mainly stone, a small amount of resin and some additives, which are made by a series of physical methods. Compared with the traditional paper manufacturing process, it is more energy efficient and environmentally friendly.

So, can stone paper replace traditional paper?

The whole process of stone paper does not require water beating and papermaking, and does not need to add a large amount of chemical agents, so it does not cause the problem of difficult wastewater discharge treatment, which is more environmentally friendly than traditional papermaking. The paper made from stone has a certain degree of whiteness, which is characterized by high tensile strength, good resistance to folding and tearing, tear resistance, water resistance, oil resistance, chemical resistance, and low temperature and humidity resistance.

In addition, the surface of the stone paper is smooth, it is not easy to grow mold, and it is not afraid of insects. Stone paper is suitable for printing, because its ink absorption is very good, and the ink printing has high definition and accuracy. At the same time, stone paper is naturally degradable, which is more environmentally friendly than traditional paper.

Of course, stone paper has its shortcomings. Under normal circumstances, the life of stone paper is about 20-30 years. However, stone paper will be powdered in less than 6 months under direct sunlight. Therefore, the storage time of stone paper is shorter than that of traditional paper. Due to such characteristics, stone paper cannot be used for storage of important documents.

In addition to storage time, stone paper is heavier than traditional paper, which is not convenient for binding and transportation. The scope of application is not as extensive as traditional paper. At present, stone paper is mainly used for printing books, newspapers, notebooks, product manuals, advertising lists, desk calendars, playing cards, and can also be made into various decorative packaging bags, shopping bags, and packaging boxes.

The main raw materials of stone paper are limestone and petroleum. The polyethylene, cement, etc. used in stone paper come from petroleum. Petroleum is a limited and non-renewable resource worldwide. Therefore, the sustainability of the development of the stone paper industry is facing severe challenges.

Traditional paper mainly uses forestry, plants and other raw materials with strong regeneration ability. As long as the country's reasonable planning forms a virtuous cycle of planting, conservation, felling, and replanting, it can meet the requirements of sustainable regeneration.

Stone paper has huge differences from traditional papermaking in terms of raw materials and production technology, which is a technological breakthrough; however, due to the narrow application range and non-renewable raw materials, it can only be used as a supplement to ordinary paper and cannot be completely replaced.

The rise of stone paper, a new material between paper and plastic, has caused controversy as a new thing.



While receiving praise, some experts also believe that although the production process of stone paper is low-carbon and energy-saving, whether it is an emerging thing or not is really worthy of discussion.

First, the raw materials of thermoformed stone paper are mainly calcium carbonate and high-molecular polymers based on petroleum. It is obviously a waste of resources for China's current consumption of nearly 90 million tons of paper products.

In addition, scientific experiments have proven that it takes at least two or three hundred years for general plastics to degrade into environmentally friendly, less harmful fragments.

Therefore, stone paper cannot be truly completely recycled and degraded. However, for renewable plant resources such as wood, reed and more than 60% of plant fiber paper made from waste paper, it is easy to recycle and degrade.

Secondly, in terms of product performance, thermoformed stone paper needs to be added with polyethylene to make a composite paper, similar to an ultra-thin "plastic paper". In comparison, traditional plant fiber paper has many excellent features such as good absorbency, air permeability, and printability. It can be converted into pulp after blistering, and easily degraded under natural conditions. These characteristics are exactly what airtight stone paper does not have.

In terms of technology, China has accumulated rich experience in papermaking for thousands of years. Modern technology has made the production process less and less polluting the environment, and large-scale enterprises have reached environmental protection standards.

The use of calcium carbonate as a filler in the paper industry has a long history. At present, paper products have been used up to nearly 20%. Therefore, the use of calcium carbonate as an ingredient in paper is no longer an innovation.

Stone paper sheet is made of marble, limestone, coal gangue, and even slag, using polymer materials and a variety of inorganic materials as auxiliary materials, using the principle of polymer interface chemistry and the characteristics of filling and modification. , Blow molding processing to produce a new type of paper that can be recycled and has modern technical characteristics.

Protect resources and save energy
The stone notepad paper board comes from the mine and does not need to cut vegetation, which is a great protection for the forest. The stone paper production process mainly uses calcium carbonate as the main raw material. The entire production process does not need to add a drop of water, which saves valuable water resources.
At the same time, the energy consumption is lower than that of traditional wood pulp and paper, which helps to improve global warming caused by carbon dioxide.

Reduce pollution emissions
The production of stone notepad paper plates does not require water washing at all, nor does it require strong acids, alkalis and bleaching agents, so there is no problem of wastewater discharge and no pollution of water resources.
Recycling and degradation

Stone heat seal paper plates can be recycled through plastic products after use. After being collected, they can be crushed and extruded to produce colored plastic bags, flower pots, and plastic buckets.

If it is treated as garbage and sent to the incinerator for combustion, no toxic gas will be generated. Because the stone paper sheet contains a large amount of stone powder and a small amount of non-toxic resin, when the resin is burned, the stone powder will be pulverized, which promotes the resin to contact with the air and accelerates the complete combustion of the resin, so black smoke will not be generated due to lack of oxygen and smoldering during combustion . After the non-toxic resin burns, there is no toxic exhaust gas, and the amount of carbon dioxide emission is small.

The thermoformed stone paper hotel products have passed the US Food and Drug Administration (FDA) test, including three types of RP \ RB \ ST stone paper series, which indicates that the stone paper products are non-toxic and harmless and can be directly contacted with food.

Legend has it that fine stones can sing, can stones make paper? The answer is yes, the waste of coal gangue can make paper is no longer a fantasy. The box made of coal gangue has a plastic feeling when touched by hand, but its toughness is very strong, and it will not tear when pulled hard. Take it in your hand, it is softer than ordinary fiber paper products. Their raw materials are not traditional pulp, but stone.

The limestone, which is made of coal gangue and tailings slag, is crushed, screened and ground to form ultrafine modified ore powder. After calcination into quicklime with a calcium content of 57% or more, it is ground into nanometer ultrafine whitening powder and added. 20% of specific PE, PP and other additives are processed by special processes such as casting and stretching, three-layer co-extrusion, blow molding, and stone paper goods.

The paper's scientific name is 'environmental synthetic paper', and its raw material is limestone. The stone content of each paper is about 70% to 80%. The characteristics of the stone wrapping paper material give it special properties. The stone carton made of this paper has a particularly high compressive strength, folding resistance, waterproofness and integral molding. According to statistical analysis of the data, the synthetic calcium polymer board has a burst strength of up to 264 KPa and a double side pressure strength compared with ordinary corrugated board. Even in the environment of minus 40 degrees Celsius to minus 80 degrees Celsius, the stone carton will not be deformed and damaged, especially suitable for the transshipment packaging of fruits, vegetables, frozen seafood and so on.

The biggest feature of large wrapping paper is environmental protection. Since the entire production process is a physical change, complete zero emissions are achieved. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of paper produced, while the entire production process of the stone paper goods process does not require water. In the raw materials, the main raw material of traditional papermaking is forest and grass resources, and the main raw materials of the stone paper production process are coal gangue, slag and other stone materials. The amount of stone wrapping paper produced by one ton of stone is equivalent to 20 trees. The most important thing is that the product can be recycled indefinitely. After the used carton is recycled, it can be directly crushed and processed without causing secondary pollution. Stone paper is not only non-flammable, but the only product produced after combustion is white calcium carbonate powder, which can be used as a raw material.

A seemingly simple stone board production line is supported by a number of production technology invention patents and new equipment patents. The solid waste such as coal gangue and tailings slag is consumed cleanly, and all are made into recyclable “green”stone paper goods.

Have you ever seen any waterproof stone notebook? Technical research and development team of Shenzhen Stone Paper Enterprise Ltd. recycled building materials, ground it into stone powder,and mixed the powder with a small amount of resin, so the "stone paper" was successfully produced. The toughness of these paper is stronger than ordinary paper, it has whiter color, and effect of waterproof. After writing, soak it in water and rub it, the paper won't break and the fonts won't spread. After drying the water, we can repeat writing on it. The paper has the following features: environmentally friendly, waterproof and not easy to burn.

The difference between stone paper and ordinary paper
The appearance of stone paper will save a lot of trees. Producing a ton of stone paper help reduce the cutting of 20 trees. In the manufacturing process, there is no need of water, agents such as bleach, strong acid, strong alkali. It does not discharge waste water, waste gas and does not produce waste. Notebooks made of stone paper cost a little more than ordinary ones, ranging from 8 to 10 yuan each.

From the perspective of environmental protection, China's waste recycling system is in a leading position in the world. For example, when you buy a car, you need to add 5000 yuan to the commission. After the car is scrapped and sent to the recycling center, you can take back 5,000 yuan. The plastic fiber clothes produced in China are made from waste mineral water bottles. This product has the vast majority of the global market share. In the field of agricultural science and technology, we hope that through the rapid development of enterprises, we can share our environmental and creative ideas and scientific and technological achievements with the world.

Stone paper disposal goods is mainly composed of stone powder (calcium carbonate), resin, etc. At present, many domestic enterprises or research institutions claim to have mastered this technology. From the information that has been published, the technologies of each enterprise are similar. The proportions are close. It's basically 80% stone powder with 20% additives. The specific addition composition, proportion and operation process are different.

It is reported, there are 3 kinds of the process of green paper such as stone paper mainly.
The first is calendering by batching, mixing, modification, extrusion materials, calendering. The shortcomings of calendering process is that it is complex, and it is generally used to produce more than 0.1mm of environmentally friendly paper products. The product proportion is big, and the equipment price is expensive, but the product surface is smooth. It is suitable for printing products like the advanced sample and the book cover.

The second is the flow method. Instead of calender, we can produce green paper of different thickness. However, the distribution of molecular chain in environmental paper is unidirectional, so the vertical, horizontal and physical properties of environmental paper products are quite different. This is a major shortcoming of environmentally friendly paper.

The third is the bidirectional stretch method. In the bidirectional stretching process, there will be some small gaps between the substrate plastic and the filling material, thus reducing the proportion and cost of environmental protection paper. Due to the refraction of light by these small gaps, the environmental protection paper produced by it has a good appearance and has been widely used in fields such as packaging, printing, advertising.

Waterproof Stone Notebook is a new material between paper and plastic. From the perspective of replacing the traditional part of paper, it can save a lot of forest resources for the society, and reduce the secondary pollution produced in the papermaking process. From the perspective of replacing the traditional part of plastic packaging, it can save a lot of strategic resources, oil, for the country. But some experts question whether it can be degraded. As a new thing, the stone paper moves on in the controversy.

What is stone paper?
Stone paper is also called stone material paper. Limestone mineral resources with large reserves and wide distribution (calcium carbonate content up to 70~80% is the main source and the high polymer is the auxiliary material (the content is 20-30%). It makes use of the chemical principle of Polymer interface and the feature of polymer modification. After special processing, it adpots polymer extrusion, blowing molding process. It is a kind of processed paper. Stone paper has the same writing performance and printing effect as plant fiber paper, and has the core performance of plastic packaging.

How does it contribute to environmental protection?
Resource conservation and energy conservation. Stone paper comes from mines. The trees do not need to be cut down. It is a great protection for the forest. Calcium carbonate is the main raw material, so no water need to adding in the process. It saves precious water resources. At the same time, the energy consumption is lower than the traditional wood pulp paper. It will help solve problems such as global warming caused by carbon dioxide.

The birth of this technology not only solves the harm of the traditional paper pollution to the environment, but also solves the white pollution caused by the use of a large number of plastic packaging materials and the waste of a large number of petroleum resources.

Stone paper is more flexible than ordinary paper. It is not easy to tear. We can write on it. It is of water and oil proof. It is said that stone paper is widely used in garbage bags, shopping bags, food bags, etc. It can also be used in cultural paper, such as printing paper, writing paper, etc. It can also be used in fields such as building materials decoration, industrial packaging. It can even be used for special paper, such as field work paper, military special paper, etc. It is widely used.

The economic benefits and social significance of stone paper are enormous
Traditional papermaking technology needs to cut down a lot of wood and use a lot of water. It discharges sewage and toxic and harmful substances in the production process, causing serious harm to the environment and human health. Throughout the production process, stone paper does not need water, strong acid, strong alkali, bleach powder and many organic chlorides. Compared with the traditional papermaking process, it saves several important pollution links such as cooking, washing and bleaching, and fundamentally eliminates the pollution problem caused by "three wastes" in papermaking process.
