Application of brown fused alumina BFA in coated abrasives
Brown fused alumina BFA is widely used in coated abrasives and has significant effects. Its unique physical and chemical properties make it an important raw material in this field. The following are the main application directions and characteristics:
1. Basic application scenarios
Sandpaper/emery cloth/sand belt manufacturing
Brown fused alumina BFA particles are evenly distributed on the surface of the substrate with high hardness and wear resistance to form a stable grinding layer. They are widely used in the manufacture of coated abrasives such as sandpaper, emery cloth, and sand belts
Surface treatment and polishing
The sharp edges of its abrasive particles can quickly remove burrs, oxide layers and scratches on metal or non-metal workpieces, improve surface finish, and are suitable for polishing a variety of materials such as stainless steel, alloy steel, ceramics, and glass.
2. Performance advantages
Efficient grinding and self-sharpening
Brown fused alumina BFA abrasives can continuously expose new sharp surfaces during the grinding process, maintain high grinding efficiency, and reduce processing time; it has high compressive strength and is not easy to deform at high temperatures, ensuring the shape stability of the abrasive.
Durability and cost optimization
High hardness and wear resistance significantly extend the service life of coated abrasives, reduce replacement frequency, and reduce comprehensive production costs by more than 30%.
Environmental characteristics
The particle density is large, and the amount of dust generated during operation is small, which meets the requirements of industrial environmental protection, and is especially suitable for scenes with high cleanliness requirements such as precision molds and glass products.
3. Special industry adaptation
Sandblasting
As an environmentally friendly sandblasting material, brown fused alumina BFA is used for surface treatment of aluminum profiles, washed jeans, etc. to enhance the adhesion of the coating while avoiding free silica pollution.
Composite abrasive tool development
Combined with materials such as black fused alumina, it can improve the sharpness and cut finish of resin abrasives and reduce manufacturing costs by about 20%.
4. Multi-material compatibility
Brown fused alumina BFA coated abrasives cover metal (such as copper, aluminum, titanium alloy) and non-metal (plastic, stone) processing fields, with strong adaptability, which can meet multi-level needs from rough polishing to fine polishing.
