Product Description

Brown corundum section sand is refined from high quality bauxite, anthracite and iron scraps by modern unique 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.
