What are the functions of white corundum as a sandblasting material?
Remove surface impurities: White corundum has high hardness and sharp cutting edges. It can quickly remove impurities such as oxide scale, rust, oil, welding slag, etc. on the metal surface. It is particularly suitable for surface cleaning of materials such as stainless steel.
Improve surface finish: The surface finish of white corundum after sandblasting is high, which can present a matte effect without changing the original color of the workpiece, thereby beautifying the surface and improving its appearance quality.
Enhance corrosion resistance and wear resistance: Through sandblasting, white corundum can eliminate tiny defects and cracks on the surface, forming a more dense and uniform surface structure, thereby enhancing the corrosion resistance and wear resistance of the material. Adjust surface roughness: By controlling the spraying speed and angle of white corundum particles, the roughness of the metal surface can be adjusted, which is very important for improving coating adhesion It is of great significance to improve the strength, sealing performance and aesthetics.
Stress elimination: White corundum sandblasting can effectively eliminate the stress on the metal surface through impact and friction, and improve the strength and durability of the metal.
Reducing costs and resource waste: White corundum abrasives have good self-sharpening properties, low grit loss, and can be recycled for multiple cycles, reducing production costs and reducing resource waste.
Stable chemical properties: White corundum has good acid and alkali corrosion resistance and stable chemical properties. It will not react chemically with the workpiece surface during sandblasting, thereby ensuring the integrity of the workpiece surface.
Wide application: White corundum is not only suitable for sandblasting of stainless steel, but also for surface treatment of materials such as metals, ceramics, glass and plastics, with greater flexibility and applicability.
