Extract calcium carbonate from limestone, then grind the ore into high-calcium 1500-2500 mesh ultra-fine powder, and then proceed to the second process, adding 85% modified calcium carbonate with 15% additive to make a masterbatch. Granules, and finally made into paper or bags through extrusion film blowing equipment. The new stone paper technology is based on calcium carbonate, the most abundant mineral resource in the earth's crust, as the main raw material, with polymer materials and various inorganic substances as auxiliary raw materials, using the principles of polymer interface chemistry and filling modification technology, and processed through special processes. It is a reversible recycling and a new papermaking technology with modern technical characteristics. Stone paper technology is a new technology that leads the world in China. The birth of this technology not only solves the problem of harm to the environment caused by traditional papermaking pollution, but also solves the problem of white pollution and a large amount of waste of petroleum resources caused by the use of a large number of plastic packaging materials.
Actually, I also saw these from the website of Shenzhen Xinghui Shengye Technology Co., Ltd. You can also check it out, it is introduced in detail above
