What are the characteristics of kaolin in ceramic materials?
The main characteristics of kaolin in chemical composition are high aluminium content and low flux content. Its producing area spreads all over the place, the south is much native kaolin, the north is much more sticky kaolin. Tyre material is porcelain clay (kaolin). Porcelain needs about 1200 degrees to burn.
The application field of consumption and consumption structure of domestic kaolin kaolin is very broad, involving ceramics (daily-use ceramics, building ceramics, sanitary ceramics, art ceramics, high voltage porcelain, low voltage porcelain and high frequency porcelain, porcelain, paper, wireless) rubber, plastics, enamel, petrochemical, paint, printing ink, optical glass, glass fiber, chemical fiber, grinding wheel, building materials, chemical fertilizer, pesticide and pesticide carrier, glue, refractories and other industries. The more than 10 series of products are ceramics, electronics, papermaking, rubber, enamel, oil, paint, grinding wheel, pesticides and pesticide carriers, glue and refractory materials, nearly 60-70 varieties. The consumption structure of our country soft kaolin for ceramic and porcelain 55%, paper 22%, other 23%. kaolin consumption structure: 65~85% 5~15% paint, paper, rubber and plastic And cable 5~10%, ceramics, 3~8%, fine chemicals, 3~5%., calcined soil consumption in the coating industry grew faster
China glaze more. The porcelain is roasted at high temperature, the carcass is firm and compact, and the section does not absorb water, knocking it out with a crisp metallic sound. To make porcelain, select the soil, especially the kaolin found by the people of Jingdezhen. Kaolin plays a key role in improving the smoothness, compactness, whiteness and hardness of porcelain.
