Brown corundum section sand
Brown corundum, also known as diamond, is a brown-brown artificial corundum made from bauxite, carbon materials and iron scraps by melting and reducing in an electric arc furnace. The main chemical composition of brown corundum is AL2O3, its content is 95.00% - 97.00%, and contains a small amount of Fe, Si, Ti and so on. Brown corundum is the most basic abrasive, because of its good grinding performance, a wide range of applications, low price, is widely used.
Brown corundum section sand made of high quality bauxite, anthracite and iron filings as raw materials by modern new special technology. The utility model has the advantages of short grinding time, high efficiency, good efficiency and low price.
The product has moderate hardness, high toughness, good self-sharpening, low sand consumption and recycling, good grinding finish, and stable chemical composition, wear resistance, acid and alkali resistance.
Brown corundum section sand has a shell-like fracture with sharp edges and edges. It can form new edges and edges in continuous grinding and grading, making its grinding ability superior to other abrasives. Especially, it has the advantages of high hardness, high specific gravity, stable chemical properties and its unique self-sharpness, which become the first choice of abrasive used in sandblasting process; at the same time, it is also an ideal material for cleaning workpieces and grinding and polishing.
The range of application of brown corundum section sand is:
Process requirements for abrasive blasting of workpiece materials Decontamination, slag removal and matte effect on stainless steel surface
Iron workpiece rust removal, decontamination, deoxidization skin, increase coating, coating adhesion.
Aluminum workpiece deoxidized, surface strengthening and finishing.
Deoxidization effect of copper workpiece
Glassware crystal scrub, engraved pattern
Plastic products (hardwood products) matte effect
Denim and other special fabrics plush processing and effect patterns
Our company can also customize various granularity brown corundum products according to user's technical and technological conditions and user's requirements.
