What are the functions of imported kaolin

　　Pure imported kaolin has high whiteness, soft texture, easy dispersion and suspension in water, good plasticity and high adhesion, and excellent electrical insulation performance; It has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, imported kaolin has become a necessary mineral raw material for dozens of industries such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals, and national defense. There are reports that Japan is also using imported kaolin as a substitute for steel in manufacturing cutting tools, lathe drills, and internal combustion engine casings. Especially in recent years, with the rapid development of modern science and technology, the application of imported kaolin has become more widespread. Some high-tech fields have begun to extensively use imported kaolin as new materials, and even high-temperature resistant ceramic components for atomic reactors, space shuttles, and spacecraft are made from imported kaolin.

　　Calcined imported kaolin for papermaking is made from high-quality coal based imported kaolin as raw material, which is processed through beneficiation, ultrafine grinding, and calcination. It has a relatively complete hexagonal lamellar structure, good porosity, reasonable particle size distribution range and excellent light scattering characteristics. Meanwhile, due to its high whiteness, low wear value, and good oil absorption, it is an excellent coating pigment mainly used for surface coating in the paper industry. It has the characteristics of reducing production costs, improving paper performance, improving ink absorption rate, good compatibility with other components, and high self adhesive concentration.
