Brown aluminium oxide F220# can be used for sand blating impeller blades in power plant?
yes, brown aluminium oxide can be used for sand blasting impeller blades.
Sandblasting is to use the sprayed brown corundum abrasive to impact and grind the surface of the turbine rotor, so as to remove rust, oil and other impurities. In order to ensure thorough cleaning and no damage to the surface, the material of the sandblasting is very important. Brown corundum is a common artificial sandblasting abrasive, and currently our domestic and foreign customers are using it.
