Product introduction
White corundum with industrial alumina powder as raw material, regularly over 2000 degrees in the arc after cooling in high temperature melting, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, granular form sharp corners, is suitable for manufacturing ceramic porcelain, resin consolidation abrasive and grinding, polishing, sandblasting, precision casting, precision casting special corundum), etc. It can also be used to manufacture high-grade refractory materials
Product advantages
1, does not affect the color of the workpiece;
2. It can be used to sandblast in the process where iron powder residue is strictly prohibited;
3, the micro powder is very suitable for wet sandblasting and polishing operations;
4, fast processing speed and high quality;
5. The amount of iron oxide is very low, which is suitable for sandblasting operation with iron residue.
6, after pickling step to remove impurities
