[0002] In the metal coating process, the surface treatment of the product is particularly important. Spraying the coating layer on the surface of metal products is a relatively mature process. Many coated workpieces are often contaminated with oil and produce oxidized rust layers during processing, factory storage or transportation. These pollutants such as oil, oxide layer, dust, and operator's fingerprints not only affect the adhesion of the decorative coating layer on the surface of the coated workpiece, but also cause particles and bubbles in the coating layer, and even cause the coating layer to fall off in pieces. Therefore, it is a very important process to clean the coated workpiece before coating processing.
