30 mesh 36 mesh 40 mesh 46 mesh brown corundum aluminum products sandblasting sand
Brown corundum is made of high-quality bauxite, iron filings, anthracite smelting in the arc at high temperature, crushed and shaped by self-mill, magnetic separation and iron removal, sieving into a variety of particle sizes, the main chemical component is Al2O3, its content is 92%–97%, and contains a small amount of Fe, Si, Ti, etc. Its texture is dense, high hardness, tan, toughness, grain formation of spherical shape, suitable for the manufacture of ceramics, resin high consolidation abrasives and grinding, polishing, sandblasting, precision casting, refractory materials, etc.

Brown corundum is called industrial teeth: mainly usedRefractories, sandblasted grinding surface treatment,Consolidation abrasives,Coating molds, etc。 1, Used in the manufacture of advanced refractory materials, castables, refractory bricks, etc.2, sandblasting——The abrasive hardness is moderate, the bulk density is high, there is no free silica, the specific weight, the toughness is good, it is ideal“environmental protection”Type sandblasting materials, widely used in aluminum profiles, copper profiles, glass, washed jeans precision molds and other fields;3, free grinding——Grinding grade abrasives, used in picture tubes, optical glass, single crystal silicon, lenses, watch glass, crystal glass, jade and other fields of free grinding, is a commonly used advanced grinding material in China;4, resin abrasive——The abrasive has suitable color, good hardness, toughness, suitable particle section type and cutting edge retention, which is used in resin abrasives with ideal effect;5, coated abrasives——Abrasives are the raw materials of sandpaper, gauze and other manufacturers; 6, functional filler——It is mainly used for automobile brake parts, special tires, special building products, etc. as highway pavement.Airstrip.dock.parking lot.Industrial flooring.Wear-resistant materials such as sports grounds; 7, filter media——It is a new application field of abrasives, using granular abrasives as the bottom medium of the filter bed, purifying drinking water or wastewater, and is a new type of water filtration material at home and abroad, especially suitable for non-ferrous metal beneficiation:Oil drilling mud aggravator:8, hydraulic cutting——It is a new, environmentally friendly and safe cutting method based on abrasive cutting medium and relying on high-pressure hydraulic jet for basic cutting, which is applied to the cutting of oil (natural gas) pipelines, steel and other components. |
