The raw materials for the production of stone paper are mainly limestone, and coal gangue and tailings slag can also be used as raw materials. After the ore block is preliminarily broken and screened by the crusher, the crushed ore is ground by the ultra-fine grinder to form the ultra-fine modified mineral powder of nanometer level, which is the main raw material for the production of stone paper. The limestone is calcined by the calcination workshop to produce quicklime with a calcium content of more than 57% After that, it was grinded into nanometer ultra-fine whitening stone powder by ultra-fine grinder. The production process of stone powder strictly follows the relevant regulations of energy conservation, consumption reduction, dust reduction and environmental protection, striving to achieve the ultimate cost control and environmental protection. The ultra-fine modified mineral powder and ultra-fine whitened stone powder are mixed with specific PE, PP and other additives in strict proportion. After being evenly mixed by high-speed mixer, they enter into the filling masterbatch extrusion equipment for anhydrous internal mixing treatment to produce different types of filling masterbatch. All kinds of filling masterbatch are proportioned to produce various types of base paper through tape drawing equipment and three-layer coextrusion equipment, or through stone paper carton and cardboard equipment to produce stone paper carton and cardboard.

Stone cardboard box technology supporting one-time forming stone cardboard box equipment, mainly produces environmental protection stone cardboard box with thickness of 1.3mm to 6mm. The environmental protection stone carton board produced by this production process has high compressive strength, folding resistance, water resistance and integrated molding, which is simple in process, low in cost and high in efficiency, and is suitable for large-scale industrial production. It is suitable for the transportation and turnover packaging of fruits, vegetables, frozen seafood, industrial parts and other products. PECC / PPCC composite base paper, as a kind of environmental protection material that can be degraded and recycled, can greatly reduce the price of logistics packaging surface materials such as bubble bags, is a real environmental protection material. It is mainly used in express e-commerce, shock absorption package and other products. The product can be directly applied to online compound bag making, bubble machine directly following compound, high-speed sealing bag making machine and other equipment, with excellent market adaptability. The patent technology supporting equipment of tape drawing mainly produces environmental stone tissue paper with a thickness of 100 microns to 200 microns and environmental stone thick paper with a thickness of 200 microns to 400 microns or more. The longitudinal tensile strength of stone paper produced by this process is good. It mainly uses copperplate paper, label, card, carton, paper box, handbag, packing bag and post seal paper. The three-layer coextrusion patent technology is matched with the technical patent of biaxially stretched utility model equipment, which mainly produces environmental protection stone synthetic paper with a thickness of 30 μ m to 120 μ M. The environmental stone paper produced by this process has good transverse tensile strength, paper softness, smoothness and ink absorption. The main sales market positioning for fruits and other packaging paper or gift box packaging soft lining.

As a new material, stone cardboard box and stone paper, on the basis of its special performance, integrated paper and plastic, meet the requirements of environmental protection, conform to the development trend and theme of "new material", "new energy", "environmental protection" and "energy saving", and make stone paper have strong and vigorous vitality! Through the correct positioning of stone paper and paperboard, the advantages of its unique physical properties, such as water-proof, moisture-proof, mothproof, chemical corrosion-resistant, oil-resistant, good mechanical properties, tear resistance, good flattening, good surface smoothness and good mechanical properties, etc., are brought into play. In the production process, no water drop is added, and zero discharge is achieved: no waste water, waste gas, waste residue discharge, from the source It has the advantages of high efficiency, easy access to raw materials, clean environmental protection, recycling and circular economy. The production process is a dry process system for inorganic material treatment, which can be degraded, reduce the emission of carbon dioxide gas at the same time, is non-toxic, has good antibacterial and other environmental protection and safety advantages; in addition to the use of carbonatite, raw materials can also use the solid waste generated by conventional mining such as coal gangue, iron ore tailings, etc., effectively realizing the reuse of waste, realizing the green circulation of mining and other high pollution industries The purpose of environmental utilization transformation.

As a high-tech and environmental protection industry, Shandong Shuifa. Jintai Hengsheng New Material Technology Co. , Ltd. is cheaper than traditional paper products in terms of price compared with paper or carton made of traditional wood pulp papermaking technology. Stone paper and carton can completely replace traditional wood pulp paper and other plant fiber paper. The proportion of stone powder in stone papermaking is more than 65%, and the cost can be reduced by 10% - 20%. When the project is completed and put into operation, the annual output will reach 120000 tons, and the sales revenue will be 584.75 million yuan. At present, we have established cooperation relationship with Haier, Hisense, Jinlongyu and other well-known enterprises, and signed product trial orders. I believe that through reasonable planning and guidance, stone paper is of great significance to improve resource utilization efficiency, accelerate structural optimization and upgrading, promote water conservation, emission reduction and consumption reduction, and enhance local development strength.

The equipment mainly produces eco-stone-based tissue paper with thickness from 100 microns to 200 microns and eco-stone-based tissue paper with thickness from 200 microns to 400 microns. The stone base paper produced by this process has good longitudinal tensile strength. Mainly used coated paper, labels, cards, cartons, cartons, handbags, packaging bags, envelope paper. The Patent Technology of three-layer co-extrusion is matched with the new practical equipment technology of two-way stretching……

Ultra-fine modified mineral powder, ultra-fine added white stone powder, special resin and other additives are mixed in a high-speed mixer, and then mixed into the extrusion equipment of filling masterbatch for waterless mixing treatment, different types of filling masterbatch are produced. Various kinds of base paper are produced by flow-drawing equipment, three-layer co-extrusion equipment, or stone-based Carton Board……
