Flake alumina for polishing

Flake polishing alumina is made of industrial alumina as the main raw material, using special mineralizing agent, high temperature control of grain shape and size, after special treatment and strict classification. Hardness is second only to diamond, is very excellent accurate grinding and polishing, grinding micro powder. Aluminum oxide flakes have strong grinding power and are not easy to produce scratches, which can get high efficiency and high precision of the machined surface.

A. The shape is flake, which increases the abrasive force, improves the grinding speed and the work efficiency, thus reducing the number of grinding machines, labor and grinding time, for example, the grinding work efficiency of the glass casing of the picture tube can be increased by 3-5 times.

B. Since the shape is flat, it is not easy to scratch the object to be ground (such as semiconductor wafers), and the qualified rate can be increased by 10% to 15%, for example, the qualified rate of semiconductor wafers can generally reach more than 99%.

C. Due to the hardness than ordinary alumina grinding and polishing micro powder, so the dosage than ordinary alumina grinding and polishing micro powder to be less, if grinding the same number of products, the dosage than ordinary alumina grinding and polishing micro powder to save 40% to 50%.
