In recent years, metal surface treatment technology has been developed rapidly and has been widely used in many fields. In the surface treatment technology and engineering, the use of metal cleaning agent cleaning, that is, pre-treatment, occupies an extremely important position, it is not only as a kind of "pre-treatment process" before the surface treatment is indispensable, but also closely related to the success or failure of subsequent surface treatment.

What is a "pretreatment process"?

The pre-treatment of matrix such as oil removal, rust removal, phosphating and rust prevention is to prepare the metal coating technology and metal protection technology. The quality of the pre-treatment of matrix has a great impact on the preparation of coating and the use of metal afterwards. For example, salt spray tests on the same coating treated with and without phosphating show a difference of about twice the corrosion resistance. It can be seen that the pre-treatment of oil removal, rust removal, rust prevention, phosphating and other metal cleaning agents plays a crucial role in the anti-rust ability of the coating and the protection ability of the metal.

What is the purpose of the "pretreatment process"?

The purpose of matrix pretreatment: one is to increase the bonding strength between the coating and the matrix that is to increase the adhesion, but the earlier the coating function such as corrosion, wear and lubrication and other special functions.

With the rapid development of metal processing industry, railway manufacturing industry and automobile industry, there are higher requirements for the production of various metal products and the quality of railway and automobile parts products. Through long-term practice, it has been proved that some simple and simple pretreatment methods can no longer meet the basic requirements of metal processing and coating. Only by using professional metal cleaning agent to improve the pretreatment production process, can the steel surface form a layer of standard phosphate film and protective film, to meet the quality requirements of metal processing and coating treatment. Therefore, the selection of low cost, low energy consumption, high quality metal pretreatment products, is an important factor for enterprises to ensure the coating quality and protection quality stability.
