Garnet sand blasting abrasive has features of good color, high hardness, long lifetime, self-sharpening,high grinding efficiency, low consumption, good finish and high recycling rate.
B.the sandblasting level of garnet sand is very high. It can penetrate into the holes and uneven parts to completely remove the oxide layer, corrosion, residual salts, burrs and other debris. The sand-blasted surface has no insert, no adverse convex point and pits, no embedded sand,and achieves SA3 blasting level with uniform surface roughness.

C.Garnet sand surface roughness can reach 45-55,50-75 microns. after sandblasting, the surface roughness is moderate which can effectively reinforce the adhesion between coatings and substrate.
