How to identify the quality of white corundum abrasive

Density is also an important indicator. The density of white corundum abrasives is divided into the packing density of white corundum and the true density of white corundum.

The packing density of white corundum abrasive is 1.53-1.99 g/cm3. The packing density of the abrasive depends on the grain size, grain size composition, type, grain shape and other factors. In general, coarse-grained abrasives have higher packing density than fine-grained abrasives. The packing density of abrasive particles is greater than that of the individual particle size.

The actual density of white corundum abrasives: the density of white corundum abrasive particles is 3.95-4.0 g/cm3. The actual density of the abrasive refers to the mass of the abrasive contained in the unit volume (excluding the volume of the opening).

specializes in the production of white corundum abrasives with high purity, good inherent sharpness, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. Hardness is slightly higher than brown corundum, toughness is slightly lower, purity is high, self-sharpness is good. Strong grinding ability, low heat, high efficiency, acid and alkali corrosion resistance, high temperature resistance, good thermal stability.
