White corundum abrasives for metal products polishing from Carrie Ge's blog

The hardness of white corundum is slightly higher than that of brown corundum, with low toughness, high purity, good self sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance and high temperature thermal stability

White corundum is suitable for sandblasting of metal products, surface treatment of glass, handicrafts and plastics, sandblasting of clocks, toys and lamps, etc. silicon carbide it can remove rust, oil, burr, impurity, oxide scale, increase friction, remove residual stress and improve mechanical properties.

Corundum is made of industrial aluminum oxide powder, which is melted at a high temperature of more than 2000 degrees in electric arc. It is crushed and shaped, removed iron by magnetic separation, and sieved into various particle sizes. Its texture is dense and its hardness is high, and the particles are spherical. Corundum is suitable for manufacturing ceramics, resin bonded abrasives, grinding, polishing, sand blasting, precision casting, etc., and can also be used to manufacture high-grade refractory materials The code "WA" is consistent with the international general standards and national standards. Most of them are for export and a certain amount is supplied to domestic users.

Product granularity according to international standards and national standards production, can be processed according to user requirements. The general particle size is F4 ~ F320, and its chemical composition varies with particle size. The outstanding feature is that the crystal size is small, impact resistance, because the autogenous mill processing broken, particles are mostly spherical particles, the surface is dry and clean, easy to bond.https://www.hslabrasive.com/

The density of corundum is divided into two types: corundum and corundum.The bulk density is 1.53 ~ 1.99g/cm3. Generally speaking, the bulk density of coarse-grained abrasive is higher than that of fine-grained abrasive, and the bulk density of mixed abrasive is greater than that of single particle size.
