Sandblasting cleaning is a very widely used process in mechanical manufacturing, where forging, casting, heat treatment and surface treatment parts, are to be sandblasted to remove
Surface oxidation, sticky sand, old coating, molten salt heat. corrosion
(1) Cleaning of the workpiece surface
After heat treatment of oxide, residual salt, residual oil, etc.; Black (have) color casting parts oxide skin, molding sand, etc.; No allowance processing precision castings of oxide, molding sand, etc.; Residue, micro burr, etc.; Oxide skin, welding slag, etc.; Cold, hot rolled steel plate (shape steel) oxide, corrosion layer, etc.; Various mold cavity release agent, sediment, etc.; Sintered residue on the surface of ceramic elements; Flash edges of plastic molding parts; Radioactive elements on the surface of objects; Bridges, hydropower station RAMS, ships, buildings; Rubber adhesive layer of airport runways; Train cars; Various pipes and containers; Oil stains and attachments of old parts; Residual paint, rust layer and attachments of containers; Wrong sintering layer on porcelain; Scratches on decorative surfaces, etc.
(2) Pretreatment of the workpiece surface before coating.
Before painting and painting; Before spraying; Before metal spraying; Galvanized, chromium, nickel before; Before oxidation treatment; Before the flaw detection.
