Introduction of Stainless Steel Sandblasting
Sandblasting is the use of compressed air flow to spray quartz sand on the surface of stainless steel parts to clean or modify the surface. Sandblasting can be divided into dry sandblasting and wet sandblasting.
Stainless Steel Sandblasting has many functions. It can remove the oxide scale on the surface of stainless steel castings, forgings, or heat treatment. It can also remove surface rust, carbon deposits, welding slag, and other sundries. It can also remove the edge burrs of the parts, some of which are slight Directional scratches. Sandblasting can also improve the surface roughness of stainless steel parts, thereby improving the adhesion of the rear surface covering layer. Sandblasting can also be used as a means of surface decoration. The surface after sandblasting is in a matt state, which is used by some industries.
Before the stainless steel dries sandblasting, the oil must be removed first, and then dried to avoid affecting the sandblasting quality, and then select the appropriate sand and air pressure according to the thickness of the part. Generally speaking, the larger the thickness, the larger the grain size of quartz sand, and the larger the airflow.
Wet blasting is to mix quartz sand and water into the mortar. If necessary, sodium nitrite can also be added, and then compressed air is sprayed onto the surface of the part. Compared with dry sandblasting, wet sandblasting eliminates the pollution of sand and dust to the air, and the processed surface is more delicate.
