How to distinguish kaolin?
Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense. Kaolin is widely used in the paper making industry. 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. Kaolin was first discovered in china.
Pure kaolin 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.
It is a used porcelain porcelain, also called white clay, commonly referred to as gaoling. The chemical formula for kaolin is Al2O3 (alumina) 2SiO2 (silica) 2H2O (water). That is to say, kaolinite is hydrous silicate. Secondly, kaolinite does not dissolve in water. Other than hydrofluoric acid, it can not be dissolved by other acids, which is one of its characteristics. To distinguish kaolinite, mineral analysis methods can also be used. 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. kaolin
