Brown Aluminum Oxide Sandblasting

Detailed introduction of sand blasting and rust removal technology knowledge:

【Common sense of sand blasting and rust removal and surface preparation】

Brown fused alumina sandblasting and derusting is powered by compressed air to form a high-speed jet beam to spray materials (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the outer surface of the workpiece surface When the appearance or shape changes, due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece. It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.

【Application Range of Sandblasting】

1. Workpiece coating and pre-treatment of workpiece bonding Sand blasting can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern (the so-called rough surface) on the surface of the workpiece, and can be passed through Replace the abrasives of different particle sizes, such as the abrasives of flying abrasives to achieve different degrees of roughness, which greatly improves the bonding force between the workpiece and the coating and plating. Or make the bonding parts stronger and better in quality. So Brown aluminum oxide and White aluminum oxide are very important material in abrasive blasting field. 

2. Cleaning and polishing of rough surface of castings and workpieces after heat treatment. Sandblasting can clean all dirt (such as scale, oil and other residues) on the surface of castings and forgings and workpieces after heat treatment, and polish the surface of workpieces to improve the smoothness of workpieces. It can make the workpiece reveal the uniform and consistent metal color, and make the appearance of the workpiece more beautiful and attractive.

3. Burr cleaning and surface beautification of machined parts Sandblasting can clean the tiny burrs on the surface of the workpiece and make the surface of the workpiece smoother, eliminating the hazards of burrs and improving the grade of the workpiece. And Brown corundum sandblasting can make small rounded corners at the junction of the surface of the workpiece, making the workpiece more beautiful and precise.

4. Improve the mechanical properties of the parts After sandblasting, the mechanical parts can produce uniform and fine concave-convex surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing noise and improving the service life of the machine.

5. Light decoration For some special-purpose workpieces, sandblasting can achieve different reflective or matte at will. Such as grinding of stainless steel workpieces and plastics, polishing of jade, matting of wooden furniture surfaces, pattern patterns on frosted glass surfaces, and roughening of cloth surfaces, etc.
