What are the advantages of silicon carbide sandblasting abrasives?
Silicon carbide is the hardest abrasive after diamond and boron carbide, but the price is only 1/10 of boron carbide, and silicon carbide comes in two colors, green silicon carbide and black silicon carbide
The hardness of green silicon carbide: Mohs hardness 9.3
Hardness of black silicon carbide: Mohs hardness 9.2
Silicon carbide has high hardness and most materials can be sandblasted and polished with silicon carbide.
Silicon carbide sandblasting can achieve the required cleanliness and a certain roughness on the surface to be cleaned at the same time, and improve the adhesion of the coating on the basic surface.
After the silicon carbide sandblasted workpiece surface is coated with industrial coatings with good performance, the coating life can be more than 3.5 times longer than the same quality coating on the surface treated by other methods. Another advantage of sandblasting is that the surface roughness can be determined in advance according to the requirements and can be easily achieved during the cleaning process.
