主要用于各种材质工件的去污、除锈、防腐、去氧化皮，光饰，效果图案等;一般来说，有三种因素决定了喷砂的效果:
1.磨削力:磨削力越高，喷砂效果越好。
2.堆积密度:堆积密度越高，喷砂效果越好。
3.粉尘:粉尘越低，喷砂效果越好。
棕刚玉高堆积密度干洗砂做喷砂用效果非常好。
this kind of brown fused alumina is mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove
oxide skin, light- decorate，process pattern effect and so on. about brown fused alumina for sand blasting.-there are three factors the
decide the effect of brown fused alumina for sand blasting:
1.the grinding ability: the higher grinding ability ,the better for sand blasting.
2.the bulk density: the h心her bulk density， the better for sand blasting.
3.the dust: the lower dust, the better for sand blasting.
brown fused alumina with high bulk density and air cleaned,the quality of this kind of brown fused alumina is very excellent for sandblasting.
