Sandblasting is the entire process of removing and passivating the surface of a substrate using a rapid sand flow. Compressed gas is used as the driving force to form a high-speed spray beam to quickly spray the spray material (copper ore sand, quartz sand, gold steel sand, iron sand, Hainan Province sand) to the surface of the workpiece to be treated, so that the outer surface or shape of the workpiece is make a difference.
Because of the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can get a certain degree of cleanliness and different surface roughness, so that the performance of the surface of the workpiece is improved, thus improving the fatigue resistance of the workpiece, and improving its and coating. The adhesion between them increases the durability of the coating.
Sandblasting Application:
(1) Rough surface of cast iron
The cleaning and polishing of the workpiece after the heat treatment process can remove all wastes (such as oxide scale, oil stains and other residues) on the surface of the precision casting and the workpiece after the heat treatment process, and the surface of the workpiece can be polished and polished to improve the smoothness of the workpiece. The surface of the workpiece is evenly distributed with the uniform primary color of the alloy, which makes the surface of the workpiece more beautiful.
(2) Machining workpiece burr removal and surface decoration
Sandblasting can remove the fine burrs on the surface of the workpiece, and make the surface of the workpiece more flat, eliminating the damage of the burrs.
(3) Improve the physical properties of parts
After the mechanical parts are sandblasted, a uniform and small attapulgite surface can be formed on the surface of the parts, so that the lubricant can be stored, thereby improving the lubrication standard, reducing noise and increasing the service life of the equipment.
(4) The decorative effect of some special-purpose workpiece
Sandblasting can easily reveal different gloss levels. Such as the grinding and polishing of stainless steel plate workpieces and plastics, the polishing of jade, the decorative patterns on the surface of frosted glass, etc.
