Kaolin crusher: application of kaolin powder in domestic
SMMVIK, the manufacturer of kaolin mill, introduced the application of kaolin powder, which is widely used in paper industry, ceramic industry, rubber industry and plastic industry.
In the paper industry, the international market of kaolin is relatively prosperous; Its sales exceed ceramics, rubber, paint, plastic, refractory and other industries. In pulp, kaolin usually does not react with its components, has strong stability, and can remain intact in paper fibers. It is also the fine particle size of kaolin, and the fluidity ensures the uniform thickness of paper coating in mechanized production. Because of these properties, kaolin is usually used as paper filler and coating in the production process.
Ceramic industry: The application of kaolin is earlier than other industries, and the amount of kaolin is also large, usually accounting for 20% of the formula? 30%。 Kaolin can increase the content of Al2O3, making the mullite formation process easier, thus improving the stability and sintering strength of ceramics. In addition, the ceramic process specifically requires the chemical properties, particle size and crystallinity of kaolin. In order to ensure the quality of ceramic processing, the parameters of kaolin should be strictly controlled in industry.
In the refractory industry: because of its high fire resistance, it is usually used to produce and process refractory products. Refractory materials are mainly divided into two types: refractory bricks and silicon aluminum wool, which have the advantages of high temperature resistance and compression deformation. Kaolin, bauxite, bentonite and a series of high temperature resistant clays are collectively referred to as refractory clays. Some of them have low whiteness, which cannot be used to process ceramics and paper, but they are good refractories of high-quality raw materials. Therefore, how to comprehensively develop and utilize kaolin, improve its utilization rate and create an important market for refractory clay and refractory materials has become a new topic of concern.
Kaolin in the rubber industry: Kaolin used in the rubber industry can be filled into the colloidal mixture to improve the abrasion resistance, chemical stability and mechanical strength of the rubber, extend its hardening time, adjust the viscosity of rubber mixing, rheology, vulcanization and vulcanization products, and prevent soft, collapse, depression, flat tube, deformation and other disintegration. Its rubber products have been greatly improved in permeability, water resistance, chemical activity, fire protection and other aspects. At the same time, kaolin can also reduce the amount of other raw materials, greatly reducing the cost of rubber, while not significantly affecting the performance of rubber.
