Nowadays, metal surface treatment technology is applied in many fields, which immediately brings about the innovation of metal surface treatment technology. The pretreatment of metal surface treatment is an indispensable step, and it also affects the success or failure of subsequent metal surface treatment. Therefore, these operating technologies and engineering before metal surface treatment play a very important role. So, what should be paid attention to before metal surface treatment?

Before metal surface treatment, it is necessary to make sufficient preparations for metal coating technology and metal protection technology, mainly including degreasing, rust removal, phosphating, rust prevention and other substrate pretreatment, and the quality of substrate pretreatment before metal surface treatment. This has a great influence on the preparation of coatings and the use of metals. For example, a salt spray test is performed on the same coating with and without phosphating treatment, and the result is that the corrosion resistance is about twice as different. It can be seen that pretreatments such as oil removal, rust removal, rust prevention, phosphating, and oil stain cleaning agents play a vital role in the anti-rust ability of the coating and the protective ability of the metal.

Before the metal surface treatment, it is necessary to carry out the pretreatment of the substrate such as oil removal, rust removal, phosphating, rust prevention, etc., because it can increase the bonding strength of the coating and the substrate and increase the adhesion; and increase the function of the coating such as anti-corrosion , Special functions such as anti-wear and lubrication. Only by adopting the production process that should be adopted before the standard metal surface treatment can a standard phosphate film and protective film be formed on the surface of the steel to meet the quality requirements of metal processing and coating and oil cleaning agent.

Before the metal surface treatment, another very important task is the degreasing and decontamination of the metal surface. Degreasing and decontamination of metal surfaces is the first pass on the exterior. The main factor that affects the operation of the next process is whether the oil removal is complete, and it also affects the quality and life of the entire product. From the process of material processing to the completion of parts processing, as well as oil stains in the storage and transportation process for anti-rust and anti-corrosion, these are oil stains on the surface of the metal, and oil stain cleaners are usually used for cleaning.
