First, the introduction of black corundum products

Black corundum is in the electric arc furnace smelting, bauxite and iron a-Al2O3 spinel based mainly black crystal, has high toughness, high temperature, thermal stability characteristics of abrasive composition of basic particle concentration, cutting force, good abrasion resistance, high efficiency.

Two. Application and application of corundum powder

Mainly used for metal products, optical glass, wood products, polishing and sandblasting, and resin grinding wheel, cutting disc, abrasive cloth manufacturing new abrasive polishing abrasive products is 2.5 times higher than the other work efficiency, completed 1.5 times, especially the grinding and polishing of stainless steel products better. Black corundum abrasive exports are packed in color cartons and plastic woven bags each weighing 25kg. Lifting sand, removing oxide layer, cleaning surface, improving strengthening degree and strengthening adhesion.

Third, the price of corundum powder producers

The Jinlin refractories plant long-term production of dense corundum price, high bulk sand corundum price hotline 08613629566279 Ningxia Jinlin dense fused corundum melting volume stability of high density, thermal shock resistance, email jlgyabrasive. Linda@outlook.com contact: lindahan
