kaolin introduction:
kaolin is a non-metallic mineral, a clay and clay rock dominated by kaolinite clay minerals.
Because it is white and delicate, it is also called dolomite. Its pure kaolin is white, fine and soft, with good physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite and quartz, feldspar and other minerals.
Kaolin is widely used in paper, ceramic and refractory materials, secondly in coatings, rubber fillers, enamel glazes and white cement materials, and in small quantities in plastics, paints, pigments, grinding wheels, pencils, household cosmetics, soaps, Industrial sectors such as pesticides, medicine, textiles, petroleum, chemicals, building materials, and national defense.
Whiteness is one of the main parameters of kaolin's process performance, and high purity kaolin is white. Kaolin whiteness is divided into natural whiteness and whiteness after calcination. For ceramic raw materials, the whiteness after calcination is more important, and the higher the whiteness of calcination, the better the quality.
