Specific Blasting Applications of Black Silicon Carbide and Green Silicon Carbide
Applications of Black Silicon Carbide Sand in Sandblasting
1. Heavy-duty surface cleaning and rust removal for ferrous metals. It is widely used for blasting treatment of steel structures, iron castings, and mechanical equipment, efficiently removing thick rust layers, heavy oxide scales, welding slag, and old thick paint coatings with its high hardness and strong cutting force.
2. Surface texturing and matting for industrial hardware. It creates uniform and rough matte surfaces on metal parts, forgings and stamping parts, improving surface aesthetics and providing excellent bonding roughness for subsequent painting, spraying and electroplating processes.
3. Burr removal and edge finishing for mechanical parts. It effectively eliminates sharp burrs, flash edges and processing residues generated by cutting, grinding and casting, optimizing the assembly accuracy and surface smoothness of industrial components.
4. Surface strengthening treatment for mechanical accessories. Blasting with black silicon carbide can form a compacted layer on the metal surface, release internal residual stress, and significantly improve the wear resistance and fatigue resistance of gears, bearings and engineering machinery parts.

Applications of Green Silicon Carbide Sand in Sandblasting
1. Ultra-precision blasting for hard and brittle non-metallic materials. It is the preferred abrasive for fine blasting and polishing of glass, ceramics, sapphire, quartz and semiconductor substrates, achieving smooth and scratch-free high-precision surface finishes.
2. Fine surface treatment for high-precision non-ferrous metals. It is suitable for blasting aluminum alloy, copper, titanium alloy and stainless steel precision parts, removing tiny oxide films and surface stains without causing excessive material loss or surface damage.
3. Mold surface fine finishing and renovation. Green silicon carbide with fine and uniform grains is used for cleaning and polishing various precision molds, removing mold scale and residue, restoring mold smoothness and ensuring the quality of molded products.
4. Micro-blasting treatment for electronic and aerospace components. Its ultra-fine particle size and stable grinding performance meet the strict precision requirements of aerospace parts, electronic components and precision instruments for surface cleaning and micro-finishing.
