Analysis of the processing method of pressure blasting machine :
The sand blasting effect of the pressure type sand blasting machine is to remove the oxide scale existing on the surface of stainless steel castings, forgings or heat treatment. At the same time, it can also remove rust, carbon deposits, welding slag and other debris on the surface, and it can also remove edge burrs. , Some slight directional scratches.
Pressure sand blasting machine uses compressed air to spray quartz sand on the surface of stainless steel parts to clean or modify the surface.
It can also improve the surface roughness of stainless steel parts, thereby increasing the cohesion of the rear surface coating. Stainless steel must be degreased and then air-dried before dry blasting to avoid affecting the quality of blasting. Then select the appropriate grit and air pressure according to the thickness of the part.
The wet blasting method of the pressure type blasting machine is to mix quartz sand and water into a mortar, if necessary, sodium nitrite can also be added, and then the compressed air is sprayed on the surface of the part. Compared with dry blasting, the air pollution from sand and dust is eliminated, and the processed surface is relatively delicate.
