First grade white corundum abrasive specification variety white corundum surface treatment
Product name: grained sand of white fused alumina
specification: 100#
Introduction of white corundum
White corundum is made of high-quality alumina powder as raw material by high temperature melting and crystallization in electric furnace above 2000 °C.After crushing, shaping and magnetic separation, iron is removed, and then a variety of particle sizes are screened out. The product has dense texture, higher hardness than brown corundum, high purity, good self-sharpening, strong grinding force, small calorific value, high efficiency, acid and corrosion resistance, high temperature resistance and good stability. White corundum abrasives are widely used in refractory materials, ceramic abrasives, resin abrasives, grinding and polishing, sandblasting, precision casting and other fields.
The advantages of white corundum in the field of sandblasting
- Does not affect the color of processed products
- It can be used for sandblasting in the process of making iron powder residue.
- Micropowder is ideal for wet blasting and polishing operations
-High processing speed, high variety
Iron oxide content is very low, suitable for strictly prohibit iron residual blasting
-After pickling, the sandblasting procedure is simplified.
