Ultrafine calcined kaolin
is an important industrial non-metallic mineral. Its scientific name is hydrated aluminum silicate (aluminosilicate clay mineral), and its chemical composition is. It is a light gray fine flake powder with triclinic crystal form and quasi-hexagonal configuration. The specific gravity is, the hardness is Mohs, and the refractive index is. It is a slightly acidic mineral, but still has good acid and alkali resistance. In addition to the characteristics of general mineral powder, it has a significant blocking effect on infrared rays, but it is easy to absorb moisture and should be dried before use. The calcined kaolin products produced by our company have high whiteness, strong covering power, bright gloss, and fine particle size. Fine, fast adsorption speed, excellent acid and alkali resistance, moderate oil absorption, stable physical and chemical properties, etc. It is a new type of plastic additive that is widely used in papermaking, coatings, inorganic pigments, cable ceramics, medicine, organic polymer industry, Grinding wheels, building materials and other industries.
Function
Pure kaolin has high whiteness, soft texture, easy dispersion and suspension in water, good plasticity and high adhesion, excellent electrical insulation properties, good acid solubility, and very Low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, kaolin has become a necessary mineral raw material for dozens of industries such as papermaking, ceramics, rubber, chemicals, coatings, medicine and national defense. There are reports that kaolin is also used in Japan to replace steel in manufacturing cutting tools, lathe drill bits and internal combustion engine casings. Especially in recent years, the rapid development of modern science and technology has made the application fields of kaolin more extensive. Some high-tech fields have begun to use kaolin as a new material in large quantities. Even the high-temperature resistant porcelain parts of atomic reactors, space shuttles and spacecrafts also use kaolin. production.
