current position：Information and data>How to choose the form of blasting abrasive
Sandblasting abrasives must be clean, dry, and angular. It is forbidden to use abrasives used after casting shot blasting for thermal spray sandblasting pretreatment. Abrasives will be crushed to varying degrees in the sandblasting process depending on the type and performance of the abrasives. The fine dust not only affects the blasting efficiency, but also deposits on the pretreated surface of the substrate, which will affect the bonding of the spray coating and pollute the environment. Therefore, when the grinding of the abrasive exceeds 20%, the fine powder should be sieved, and the abrasive should be cleaned and dried before use. It is best to use a mixed abrasive of 50% recycled abrasive + 50% new abrasive for reuse.
