The importance of metal surface treatment and its pre-treatment process

The reason for choosing metal surface treatment is because it can avoid external corrosion and oxidation. Although there may still be some costs involved in processing, we also need to know that the entire processing can greatly help extend the service life.

Many products and materials themselves have high costs, and if their lifespan is very short, this can cause significant problems. After metal surface treatment, it can make its surface look better. At least when using it, you will find that the entire process will be smoother. However, if left untreated, the external aesthetics may not be very sufficient, which can have a serious impact on us all. At this time, it is necessary to truly consider these practical aspects to ensure the smooth completion of the entire matter.

The quality of metal surface treatment directly affects the adhesion of the coating to the substrate of the coated workpiece and the corrosion resistance of the material. Therefore, in order to obtain high-quality products, it is necessary to strictly carry out surface treatment operations before painting. By pre-treatment, the workpiece is made free of oil and moisture; No rust or oxides; No acid, alkali or other residues; The surface of the workpiece meets certain requirements such as roughness.
