White corundum used for sand blasting？

White corundum used for sand blasting mainly consists of silicon carbide sand. White corundum is mainly distinguished by mesh size (micro powder) and millimeter (particle). White corundum polishing mainly relies on sandblasting machines for processing: coating the workpiece with different grit sizes, and sandblasting before bonding the workpiece can remove dirt such as rust on the surface of the workpiece, and establish a very important basic pattern (commonly referred to as a rough surface) on the surface of the workpiece.

The commonly used white corundum grain size sand (No. sand) should have a grain size that matches the working requirements, generally between 8 # and 220 #. The sand should be kept dry, and the air pressure should not exceed 0.8MPa.

Abrasives for sand blasting shall have high compressive strength, multiple uses, polygonal and prismatic grain size, and certain cutting ability. To achieve a certain degree of cleanliness and different roughness on the workpiece surface, and to improve the mechanical properties of the workpiece surface.
