?As we all know, often the oil, dust and dirt on the surface of the workpiece are the big enemies of the coating construction, and if the surface of the workpiece cannot be cleaned, the coating failure is inevitable. In order to avoid this phenomenon, we must do a good job of surface cleaning before using automatic painting equipment for painting.
　　Professional automatic coating equipment manufacturers remind you that good surface cleaning must: (1) determine the correct cleaning steps; (2) surface cleaning should be thorough; (3) eliminate all factors or external conditions that may cause pollution to the cleaned surface again.
　　Before using tools or machinery for surface cleaning of steel, all visible oil must be removed beforehand. Otherwise, these oils will contaminate a wider range of surfaces.　　A certain amount of dust will remain on the surface of the workpiece after cleaning by tools or spraying, and these dust must be cleaned before painting. The general practice is to clean the surface first and then clean it with a vacuum cleaner or clean compressed air. If the dust contains lead or other toxic components, the surface should only be cleaned with a vacuum cleaner. The cleaned surface should be guaranteed not to be contaminated again. If you don't pay attention and neglect to clean the environment around the workpiece, the workpiece will be in danger of being contaminated when painting.
　　I hope the above introduction can let you understand the importance of surface cleaning work before painting work, hope you pay attention to it!
