Kaolin is a kind of non-metallic mineral, which is a kind of clay and clay rock dominated by kaolinite group clay minerals. Because it is white and delicate, also known as China clay, dolomite. Its pure kaolin is white, delicate, soft, with good plasticity, corrosion resistance, fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, Eloite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals.
Size: 200 mesh, 325 mesh, 600 mesh, 800 mesh, 1250 mesh, 4000 mesh, 6000 mesh and more.
Application:
1. Ceramic industry. First of all, kaolin has good plasticity, which can increase the plasticity and ductility of ceramic products and facilitate molding. Secondly, kaolin has high cohesiveness, which can promote the bonding of ceramic billets and improve the strength and toughness of ceramic products. It has high resistance to high temperature.
2. Paper industry. Kaolin as a slurry binder can help the fiber particles disperse evenly in the slurry, reduce the waste in the paper production process, and effectively reduce the cost of paper industry.
3. Cosmetics industry. Kaolin has super absorbability, oil absorption and other effects. Mainly used in powder, foundation, eyeshadow, talc powder, loose powder, blush and other cosmetics to meet the beauty needs of different consumers.
4. Refractory materials. Kaolin is mainly used in the production of refractory materials, semi-acid refractory materials and special refractory materials (such as melting crucible, optical glass and control glass fiber, can replace platinum crucible), can improve the temperature stability and erosion resistance, improve the thermal conductivity of the material, control volume shrinkage, etc.
5. Rubber industry. Kaolin can improve the glass transition temperature and insulation property in rubber. Enhance wear resistance, chemical stability and mechanical strength, extend the hardening time, and adjust the mixing, rheology and vulcanization of rubber.
6. Plastics industry. Kaolin has the characteristics of high viscosity, high dispersion and fine particle size, so that the composite in the plastic is more uniform distribution, and improve the density, hardness, compressive strength and high temperature resistance of the plastic. The surface of plastic products is smooth, the size is accurate, the chemical corrosion resistance is reduced, the thermal shrinkage and thermal fission are conducive to the polishing process.
7. Paint industry. Kaolin can increase the viscosity and rheology of the coating, improve the adhesion and wear resistance of the coating, and increase the hardness and durability of the coating. Kaolin can also play a role in whitening, filling, thickening, enhancing softness, reducing shrinkage, etc., so that the performance of the coating can be improved, and the color can be better.
