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 ., 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.
At present, ceramics, rubber, plastics, artificial leather, self-cement, refractory materials, chemicals and other industries as well as agriculture are not widely used. With the further improvement of kaolin beneficiation technology, the application scope of kaolin will become increasingly wider. The coalfield geological system preparation unit can proceed from the actual situation and base on the kaolin resources and market demand in the coal-bearing strata. Kaolin is a non-metallic mineral ubiquitous in nature. In the past, it was generally used in the production of ceramics, refractory materials and a small amount of filler mixed in plastics and rubber. With the increasing development of various fields of the national economy, people are paying more and more attention to the deep processing of kaolin, because this can not only obtain new materials with special properties, but also improve economic benefits. One of the deep processing methods of kaolin is to further heat, roast, and dehydrate the kaolin that has been washed, dried, and ground to turn it into metakaolin, which can be used as a filler in plastic cables to improve the insulation of the cable sheath. performance. Commonly used footwear rubber fillers mainly include organic fillers and inorganic fillers. The former includes reclaimed rubber and recycled materials, etc., and the latter includes white carbon black, calcium carbonate, titanium dioxide, magnesium carbonate, magnesium oxide, carbon black and Zinc oxide powder, etc. Kaolin is a new type of rubber product filler developed in recent years.
