Product Description

 

The use of brown corundum powder

Making grinding tools: can be used as consolidation and coating grinding tools, such as for manufacturing abrasive paper, grinding wheel and other abrasive materials and grinding tools, processing and surface treatment of various materials

Grinding and polishing: used for grinding and polishing of metal, ceramics, glass and other materials to obtain a smooth, flat surface

Anti-skid materials: can be added to the floor, stairs and other anti-slip materials to enhance its anti-skid performance

Ceramic materials: as an additive of ceramic materials, improve its hardness, wear resistance and high temperature stability

Refractory materials: used for the production of refractory materials, such as refractory bricks, refractory coatings, etc., to improve their fire resistance
