White fused aluminum oxide 22# is a type of corundum, with an alumina content of over 99%. The particle size range of aluminum oxide sand used for sandblasting is strictly controlled, ensuring that the abrasive particle size is controlled within a certain range. After sandblasting, a consistent surface roughness is produced. White corundum has good toughness, strong grinding ability, and good self sharpening. When sprayed onto the surface of sandblasted workpieces, the impact force of the airflow causes the workpieces to collide with dents. The sandblasted surface after passivation is beneficial for maintaining the grip of subsequent paint spraying. White alumina sandblasting abrasive particles also have the advantages of high sandblasting efficiency and high utilization rate.
