I only know that is a kind of raw material, and sell them where to sell, and I can have to contact the white mud!
Also known as white kaolin clay, kaolin is pure with high whiteness, soft, easy to disperse in water, suspended in plasticity and good adhesion, high excellent electrical insulation properties; has good acid soluble cationic, low resistance and other physical and chemical properties, better exchange. Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense.
There are two main areas. One is used in papermaking (or paper making), and the other is the pigment used in the surface coating process. For general cultural paper, the amount of filling accounts for 10-20% of the weight of the paper. For coated paper and paperboard (kaolin ore mainly includes light weight coated paper, coated paper and paperboard), in addition to the packing, also need to fill, pigment, pigment with kaolin accounted for paper weight 20-35%. Kaolin used in paper making, the paper can give good coverage performance and good gloss coating performance, but also increase the paper whiteness, opacity, smoothness and printability, greatly improve the quality of the paper. The main production of ceramic white mud to local sales.
At present, the global total output of about 40 million tons of kaolin (the data belonging to the simple country and production together, in which no statistical ore trade volume, including more repeat calculation), which is about 23 million 500 thousand tons of refined soil. The paper industry is the largest consumption Department of refined kaolin, accounting for about 60% of the total consumption of kaolin. According to data provided by Temanex consulting Canada, the total output of paper and paperboard in the world was about 319 million tons in 2000, and the total amount of kaolin used in the world's paper coating was about 13 million 600 thousand tons. Kaolin is widely used in the paper making industry.
There are reports that Japan has also used kaolin instead of steel, cutting tools, lathes, drills, and internal combustion engines. Especially in recent years, the rapid development of modern science and technology, the application of kaolin is more extensive, began extensive use of kaolin as new materials in some high-tech fields, and even nuclear reactor space aircraft and spacecraft components with high temperature porcelain, made of kaolin.
