Surface mechanical rust inhibitor treatment; surface chemical rust inhibitor treatment; surface electrochemical rust inhibitor treatment; spraying polymer (physical rust inhibitor treatment); other physical methods of rust inhibitor treatment.
Surface mechanical rust inhibitor treatment is usually only used as a rust preventive treatment method, including sand blasting, shot blasting, sweeping or polishing, to provide a uniform, smooth, smooth or textured, or shiny, beautiful surface for further surface rust inhibitor treatment However, surface mechanical rust inhibitor treatment is generally not the final measure of surface rust inhibitor treatment. In other words, the surface treated with the surface mechanical rust inhibitor is not the surface in use.
The chemical conversion rust inhibitor treatment, such as chromization, phosphorus chromization, chromium-free chemical conversion, etc., may not only be the bottom layer of the spray coating later, but also a final surface rust inhibitor treatment method. The chromated film is a protective film of a copper alloy that is still being used. Electroless nickel plating on the surface of copper alloys is also called electroless nickel plating. It can also be said to be a surface chemical anti-rust treatment to obtain metal plating.
Surface chemical rust inhibitor treatment, generally have chemical rust inhibitor treatment and chemical conversion rust inhibitor treatment. Chemical rust preventive treatment is not the final surface rust preventive treatment measures, such as degreasing, alkaline cleaning, pickling, chemical polishing, etc., so that the metal surface obtains a clean, no oxide film or bright surface state to ensure and improve the subsequent surface The quality of rust inhibitor treatment (such as anodizing).
