Kaolin action

Kaolin has become a necessary mineral material for dozens of industries such as papermaking, ceramics, rubber, chemical engineering, coatings, pharmaceuticals, and national defense. There are reports that Japan also uses kaolin as a substitute for steel in the production of cutting tools, lathe drills, and internal combustion engine casings. Especially in recent years, with the rapid development of modern science and technology, the use of kaolin has become increasingly widespread. Some high-tech fields have begun to extensively use kaolin as a new material, and even high-temperature resistant ceramic components for atomic reactors, space shuttles, and spacecraft are made of kaolin.

Calcined kaolin for papermaking is made from high-quality coal based kaolin through mineral processing, ultrafine grinding, and calcination. It has a relatively complete hexagonal lamellar structure, outstanding porosity, reasonable particle size distribution range and excellent light scattering characteristics. Together, due to its high whiteness, low wear value, and good oil absorption, it is an excellent coating pigment and is primarily used for surface coating in the papermaking industry. It has the characteristics of reducing production costs, improving paper performance, improving ink absorption rate, outstanding compatibility with other components, and high intrinsic viscosity.
