glass blasting electrically micro powder of white fused alumina high quality low sodium strong cutting force
Product name: grained sand of white fused alumina
specification: W7
White corundum powder, white, strong cutting force. It has good chemical stability and good insulation.
Applicable scope : Wet or dry jet sand, suitable for crystal, electronic industry super fine grinding and polishing and production of advanced refractory materials.
The characteristics of white corundum powder :
-High processing speed and high quality
- Does not affect the color of the workpiece
Micro-powder grade is ideal for wet blasting and polishing
- It can be used for sand blasting in the process of making iron powder residue.
The very low amount of iron oxide contained is suitable for strictly prohibiting the blasting of iron residue.
The use of white corundum powder :
- Advanced grinding and polishing.
- Available in various sandblasting and polishing.
-Atomizing aesthetic processing of Polly or acrylic artworks.
- Precision casting sandblasting.
- Silicon crystal cutting.
- Clean sandblasting of tooth model.
- Additives for advanced refractory materials and other ceramics.
- Sandblasting in the process of TV screen production.
