This method is currently applied widely as a descaling method, the principle is the use of impact and friction effectively remove rust and dirt. This method is commonly used in portable electric Grinding Wheel, electric brush, brush pneumatic, derusting guns. The advantage of this method is that rust quality, efficiency are high, but the drawback is that these tools also require manual operation, greater labor intensity of geometrically complex parts and precision is not applicable, not suitable for large-scale blasting needs. It is more extensive or spraying and blasting two treatments rust dirty methods currently applied.
(1) This method is mainly blasting sand blasting, shot blasting, vacuum blasting, high-pressure and high-pressure water, sand and water.
(2) This is a high-speed shot blasting iron pellet (pellet or other materials) the impact of a use of high-speed rotating impeller blast wheel thrown, with the friction between the parts of the surface to clean rust and achieve the purpose.
