Metal surface treatment methods and application range
Approach | Application range |
manual derusting | Castings, forgings, steel parts surface to remove floating rust, easily peeling oxidation degree, molding sand, old paint layer. It is mainly used for treatment when it is inconvenient or unable to use other equipment. |
Electric and Pneumatic Tools | Remove rust, oxide skin, molding sand, old paint layer, weld repair. Applicable to the exterior of various products. |
Dry blasting, wet blasting, shot blasting, shot blasting | Remove oxide skin, rust, molding sand and old paint film on medium and large products with a thickness of not less than 1 mm or on castings and forgings that do not require accurate dimensions and contours |
Vacuum blasting | It is suitable for small parts with uncomplicated shape and small curvature. other ditto |
Flamethrower | It is mainly used for large-area facilities with a thickness of not less than 5 mm, such as bridge structures, storage tanks and heavy equipment. Each, remove scale, rust, old paint, grease and other pollutants |
High pressure water, high pressure water sand, steam treatment | Remove loose rust, scale, old paint, grease and other pollutants in large-area facilities (such as factories, bridges, storage tanks, ships, etc.) |
chemical, electrochemical rust removal | It is widely used to remove rust and scale of ferrous metals and oxides of non-ferrous metals. According to different plates, profiles and products, different methods, formulas and process conditions can be used |
surface chemical transformation | In order to enhance corrosion resistance or paint and decorate various metal parts, it is widely used, and it is also treated in different ways depending on the requirements and conditions. |
Bath caustic washing (with or without heating lye) | Remove the old paint film and oil stains on the surface of metal parts |
Paint remover cleaning, paint remover | It is widely used to remove the old paint layer on the surface of various parts |
Solvent cleaning (acetone, trichloroethylene, gasoline, xylene) | It is suitable for degreasing and degreasing of various metal parts and metal products of any size and any geometric shape. |
