Stone paper: the development trend of environmental protection in the future

the main raw materials of stone paper are calcium carbonate, the most abundant mineral resource in the earth's crust, and other auxiliary materials and additives below 20%, which are produced and processed by polymer processing technology. This new type of paper breaks through the paper-making technology that has been used for more than 2000 years with wood pulp and straw pulp as raw materials. It is waterproof, tear resistant and degradable. In addition, it can greatly reduce the emission of carbon dioxide and other pollutants in the production process. If the annual output of 5.4 million tons is reached, 8.64 million cubic meters of wood can be saved every year, which is equivalent to reducing the deforestation of 1016 square kilometers, At the same time, it also refers to the system that controls the operation of the experimental machine to reduce carbon dioxide emissions by 1.76 million tons, save 1.465 million tons of standard coal, and reduce sulfur dioxide emissions by 500000 tons. It is expected that this kind of paper will be fully launched on the Beijing market in March this year

the appearance of this stone paper is no different from that of traditional paper. It should be more tenacious to touch, not easy to tear, waterproof, oil-proof and non-toxic. It can be used for writing, making notebooks, shopping bags, tablecloths, paper, special paper, etc. The cost of stone paper is 10% to 20% lower than that of similar products. It can be degraded after 3 months under the sun, and can be buried underground for 1 year. After degradation, it will become stone powder. The main raw materials of stone paper are calcium carbonate and polymer materials. Calcium carbonate mainly comes from calcite, marble, limestone and other ores, which are very abundant in China, so the stone paper industry has great development prospects

according to the introduction of senior technical experts, a key to stone paper-making is the grinding of raw materials. The main raw materials of stone paper are calcite, marble, limestone and other ores. After the superfine grinding is carried out to improve the cement quality assurance capacity, the powder machine is improved and the role of the industry expert advisory committee is played. After special processing, the superfine powder with more than 350 mesh is fully mixed with 15% polyethylene and 5% adhesive, and the finished product is Stone paper. Liming heavy industry technology has been engaged in the R & D and production of ultra-fine pulverizer equipment for decades, and has always taken the technical innovation of equipment as the driving force for the development of the enterprise. It has successively launched Raymond pulverizer, high-pressure micro pulverizer, high-pressure suspended roller pulverizer, three ring medium speed micro pulverizer, Vertical Pulverizer, trapezoidal pulverizer, etc., which can facilitate the adjustment of material fineness and output, The comprehensive performance of economic effectiveness is widely used in major industrial and mining enterprises, and it is more suitable for the rational choice of small and medium-sized investors. It has mature experience and unique technical advantages in dealing with calcite, marble, limestone, etc. at present, it has provided many calcium carbonate industrial milling and processing enterprises with excellent performance mill products, enjoying good reputation and reputation among users

the emergence of stone paper will help to improve the environmental problems in the past and conform to the trend of environmental protection in the future. It is believed that it will be an inevitable and widely used product of the development of human science, and will inevitably receive more and more attention. The market prospect is very broad
