Compared with un calcined kaolin, the bound water content of ultra-low temperature calcined kaolin decreases, the content of silicon dioxide and aluminum trioxide increases, the vitality point increases, and the structure changes. The particle size is small and uniform. Compared with un calcined kaolin filled with NR plastic particles, the vulcanized rubber characteristic curve of ultra-low temperature calcined kaolin filled with NR plastic particles is basically consistent, and the Shore A-type strength does not change, while the tensile strength increases, The process performance of both meets the requirements of the national standard for non fully transparent sole of casual shoes.

Recently, industrial production such as porcelain, vulcanized rubber, plastic, artificial leather, self concrete, fire-resistant insulation materials, organic chemistry, and other industries have not been widely used in agriculture and animal husbandry. With the further improvement of kaolin beneficiation technology, the application scope of kaolin will become increasingly common. Coal field geological environment system software companies can consider specific situations and focus on the kaolin resources and market demand in coal geological structures. Kaolin is a common phenomenon in nature in mining enterprises. In the past, it was generally used for the production and manufacturing of porcelain, fire-resistant insulation materials, and small amounts of added plastic, vulcanized rubber as fillers. With the increasing development trend of various industries in the social economy, people are increasingly attaching great importance to the precision processing of kaolin. This not only enables the acquisition of new raw materials with unique characteristics, but also enhances economic benefits. One of the production and processing methods for kaolin is to further heat, cultivate, and dehydrate the kaolin that has been rinsed and subjected to tough step drying treatment to become metakaolin, which can be used as a filler for plastic cables to improve the insulation performance of cable sheaths that are too long. There are two key types of common vulcanized rubber fillers for shoes: organic chemical fillers and inorganic fillers. The former includes recycled rubber and recycled materials, and the latter includes white carbon black, Calcium bicarbonate, polyethylene wax, calcium sulfate, magnesium oxide, carbon black, zinc oxide powder, etc. Kaolin is a new type of filling agent for rubber and plastic products developed and designed in recent years.

However, all applications of kaolin must go through production and processing to become ultrafine powder before it can be added to other raw materials and completely combined.
