White aluminum oxide 70mesh blasting media for sanding belt cloth

Sanding belt cloth and sand belts are common mechanical polishing tools. They are sort of coated abrasives. Before electrostatic sand planting, the fabric substrate of the sandcloth needs to do surface treatment. The common method is to blasting with white aluminum oxide blasting media. This sandblasting can increase surface roughness. Thus improve the grip strength of abrasive particles. The white aluminum oxide 70mesh blasting media is a proper grit for this application.

White aluminum oxide 70mesh produced in a fixed furnace has high durability. Because after a long period of smelting, the cooling time of the fixed furnace is short, and the crystal size is smaller. During each sandblasting process, less white aluminum oxide crystal falls off due to abrasive impact. Therefore, compared to the pouring furnace white corundum, the fixed furnace white aluminum oxide 70mesh has a higher cost-effectiveness.
