Purpose of cleaning and purification before spraying

       Substrate surface decontamination treatment is mainly used to remove dirt from all sprayed surfaces, including oil stains, grease, paint and rust. The heat of the spraying process cannot remove these contaminants, and if these contaminants are not removed thoroughly, they will seriously affect the adhesion of the coating to the substrate. Keep the clean surface after the dirt has been removed. When the parts to be sprayed are transported, it is necessary to wrap them with clean wrapping paper and use cleaning tools to avoid secondary pollution of the surface. Surface purification treatment mainly includes surface degreasing treatment and surface rust removal treatment. Mechanical and chemical methods are often used to achieve the purpose of surface purification.
