Alumina The main components of high temperature alumina powder for polishing are-Al2O3 powder that has been calcined at high temperature, in addition, it contains dispersant, levant, lubricants, emulsifiers, etc., mainly used in the tableware industry, accessories industry, auto accessories, optical lenses, machine and electrical accessories and other industries that require surface processing. Brief Introduction The main component of high temperature alumina powder for polishing is-Al2O3, which also contains dispersant, suspension agent, lubricant, emulsifier and other auxiliary components, which is widely used in machine preparation, optical processing, jewelry processing, automobile repair and maintenance and other fields. Ingredients: Aluminum oxide polishing powder, the main component is calcined-Al2O3 powder after high temperature. Usage: mainly applied in the tableware industry, accessories industry, auto accessories, optical lenses, machine and electrical accessories and other industries that need surface processing. Crystal hardness: the calcination temperature of preparing alumina polishing powder is high, generally above 1600, so as to ensure that the product has a very good hardness. Single crystal size and shape: single crystal size determines the thickness of the surface lines of the polished product, not easy to clear light. Round or elliptic crystals are easy to throw black and bright light, the diamond crystals are easy to throw yellow and white light, and the sheet or flocculent crystal grinding force difference is not easy to produce light. Average particle size and distribution: different polishing process according to the average particle size, generally 20-45 渭m particle size is used in coarse throwing process, 4-20 渭m, particle size is used in medium throwing process, 1-4 渭m particle size is used in fine throwing process, and below 1 渭m for mirror polishing. The narrower the particle size distribution, the higher the polishing efficiency. Current situation: the domestic high-grade alumina polishing powder is mainly imported, imported powder is generally air flow grinding processing, the physical and chemical indicators of the powder are relatively stable. Domestic aluminum polishing powder manufacturers are mainly concentrated in Henan, Shandong, Guangdong and other areas, now the main domestic manufacturers are East Henan Mineral Products Co., Ltd., YUECHANG abrasive grinding Co., Ltd. and other manufacturers. Quality The quality factors of alumina polishing powder include particle size distribution and particle microlight morphology. The maximum particle size in the particle determines the polishing accuracy of the polishing powder, and the average particle size determines the polishing rate of the polishing powder. The particle shape of alumina powder affects the roughness and polishing defects of the polishing surface, smooth surface particles are not easy to produce scratches, polished surface finish is high; and angular particles are easy to produce scratches.Alumina website:http://www.sd-alumina.com/alumina/
