White corundum abrasive is made of industrial alumina powder as raw material, smelted at a high temperature of more than 2000 degrees in an arc, crushed and shaped, magnetically separated from iron, and screened into a variety of particle sizes.
The outstanding feature is that the crystal size is small and impact resistant, because it is crushed by self-grinding machine processing, the particles are mostly spherical particles, the surface is dry, and it is easy to combine with the bond.
White corundum abrasive has the characteristics of white color, high hardness, low toughness, high purity, excellent self-sharpening, strong grinding force, small calorific value, high efficiency, acid and alkali corrosion resistance, high temperature resistance and good thermal stability.
White corundum is currently the more commonly used abrasive on the market, its main chemical composition is AL2O3, according to the content of alumina powder, can be divided into first, secondary and other grades. The basic grain size of white corundum is an important indicator to ensure the grinding effect, because white corundum sand is widely used, so it also plays a great role, in the production should be able to be properly controlled, the bulk density of the abrasive and the particle size of the abrasive, but the production speed may slow down.
White corundum is suitable for a variety of high-end products, handicrafts or hardware and other products surface landscaping, the general particle size number is F4~F220, to continue to give full play to the advantages of the traditional white corundum industry.
Learn about the benefits of white corundum products:
1. Does not affect the color of the processed parts;
2. It can be used for sandblasting in the process where iron powder residues are strictly prohibited;
3. Micronized grade is very suitable for wet sandblasting and light polishing operations;
4. Fast processing speed and high quality;
5. The amount of iron oxide contained in it is extremely low, which is suitable for sandblasting operations where iron residues are strictly prohibited;
6. Go through the pickling step to remove impurities.
White corundum abrasive is not only a high-grade abrasive abrasive material, but also a high-grade grinding and polishing material, etc., and the abrasives made of it are suitable for grinding high-carbon steel, high-speed steel and various stainless steels. White corundum abrasives are also widely used in precision casting, steel refractory, chemical refractory, decorative porcelain and other special ceramics and daily
