White Fused Alumina Manufacturer In China

What is brown fused alumina polishing material? Polishing material is metal, stainless steel and hardware. It uses powder mixture such as alumina and cerium oxide to deal with workpiece (deburring, cutting edge, oxide skin, etc.). What is grinding powder? Grinding powder is used to improve and polish metal and other workpiece materials, surface allowance or roughness of powder. Technical requirements for pink corundum grinding powder of metal polishing materials in China.

What is metal polishing material grinding powder? Polishing material grinding powder is usually composed of ceria, brown aluminum oxide, silicon oxide, iron oxide, zirconia, chromium oxide and other components. Different materials have different hardness and chemical properties in water, so the application occasions are different. The hardness of silicon carbide abrasive and chromium oxide is 9, that of ceria and zirconia is 7, and that of iron oxide is lower.(white fused alumina manufacturer in china)

Ceria and silicate glass have high chemical activity and similar hardness, so they are widely used in white corundum glass polishing. In order to increase the polishing speed of ceria, fluorine is usually added to the ceria grinding powder to increase the grinding rate. The mixed rare earth grinding powder with lower cerium content is usually mixed with 3-8 fluorine; the pure ceria green carborundum grinding powder is usually not mixed with fluorine.

(white fused alumina manufacturer in china)For ZF or F series glass, because its hardness is small, and the fluorine content of the brown fused aluminum oxide material itself is high, so it is better to choose the grinding powder without fluorine. First, it has high purity and does not contain mechanical impurities; second, it has good dispersibility to ensure the uniformity and high efficiency of the silicon carbide companies processing process, and it can increase the suspension rate by adding a proper amount of dispersant.

Third, the particle size of the black aluminum oxide micro powder is uniform and within the allowable range; fourth, the grinding powder of metal polishing materials has appropriate hardness and density, and has good wettability and suspension with water, because the grinding powder needs to be mixed with water; fifth, the powder particles have a certain lattice shape, forming sharp edges and corners when breaking, so as to improve the black fused alumina polishing efficiency.(white fused alumina manufacturer in china)
