Description

Brown Fused Alumina is made of high quality bauxite as the main raw material and auxiliary materials. It is refined, purified, impurity removed, crystallized, sorted, broken, magnetically separated and screened at a high temperature above 2250 ℃ in the electric arc furnace to produce products of various particle sizes.

Brown Fused Alumina sandblasting

Product introduction：

Product specification：

12# 16# 20# 24# 30# 36# 40# 46# 54# 60# 70# 80# 90# 100# 120# 150# 180# 220# 280# 320# 400# 600# 800# 1000# 1200# 1500#

Product advantages and application scope：

Weixiang Brown Fused Alumina abrasives are mainly used for decontamination, derusting, anticorrosion, descaling, polishing and effect pattern of various materials.

Generally speaking, there are three factors that affect the effect of sandblasting:

1. Grinding force: the higher the grinding force, the better the sand blasting effect.

2. Packing density: the higher the packing density, the better the sandblasting effect.

3. Dust: the lower the dust, the better the sand blasting effect.

Brown Fused Alumina dry cleaning sand with high packing density has a very good sandblasting effect.
