Use Of White Corundum Abrasives

White corundum is made of industrial alumina powder as raw material, melted and smelted at high temperature above 2000℃ in electric arc furnace, cooled and crystallized to obtain white corundum frit. White corundum and industrial alumina powder also contain alumina, so why do you need to melt it? This is because many of the excellent properties of white corundum come from the α-Al2O3 crystal, and the alumina content of industrial aluminum oxide powder is only about 98%, which not only contains other impurities, but also contains Al2O3 isomers, which will significantly reduce the various properties of corundum materials. Therefore, it is necessary to remove impurities by melting, purify the alumina content, and form α-Al2O3 crystals by re-cooling the crystals.

Refers to the particle size range of 0-1mm, 1-3mm, 3-5mm, 5-8mm, 100#-0, 200#-0, 320#-0 and other granularity of white corundum products. The high-quality white corundum bulk produced by the smelting workshop is transported to the sand production workshop, broken by the rough breaker and then screened, and the white corundum product with a particle size within a certain range is finally obtained. Mainly used as shaped refractory, amorphous refractory and floor sand and other applications.

White corundum fine powder: belongs to the white corundum sand, the products of 0 to a certain particle size in the sand are also called fine powder, which is the product through the finest screen in the white corundum sand production line, the general models are: 100#-0, 200#-0, 320#-0, 0-1mm. It can be used as high quality refractory powder for shaped refractories and amorphous refractories. At the same time, the white corundum fine powder can be further ground, processed and screened into white corundum sand and white corundum micro-powder.

1. grinding: white corundum abrasive is mainly free grinding, glass, jade products, these materials can be ground with white corundum, you can also use ceramics, precision workpiece grinding, abrasive is mainly used for grinding white corundum, brown corundum, black corundum, silicon carbide, iron sand, copper.
2. abrasive tools: white corundum abrasive used in the production of resin grinding machines, coated abrasive tools, these words have made a certain summary, that is, white corundum and brown corundum can produce sandpaper grinding wheel gauze.
3. sandblasting rust removal: stainless steel, iron, copper workpiece can be sandblasted with white corundum, because white corundum abrasive can purify, deoxidize skin, increase coating, interlayer adhesion, can also be used for plastic products and glass products, as well as cowboy sandblasting operations.
4. filling: the use of floor materials the most, can be used for factory sites, sports fields, tracks, parking lots and other places. In fact, due to the higher price of white corundum, black corundum and inferior brown corundum are often used as abrasive floor materials.
5. white corundum abrasive can be used in all kinds of sandblasting (steel, aluminum, copper sandblasting) and polishing (grinding and polishing) operations; Atomized aesthetic processing of various crafts; Sandblasting in TV screen manufacturing process.

6.white corundum abrasive can be used for cutting silicon; Clean sandblasting of tooth die; White corundum sand for precision casting; Auxiliary additives for high quality refractory materials and other ceramics; High quality grinding and polishing.
