Development of the automotive industry

With the rapid development of China’s national economy, the automobile industry has ushered in a period of rapid development. Along with the substantial increase in automobile production, people have put forward higher requirements for the quality of automobiles.

In the automotive painting production line, from the car body pretreatment → electrophoresis → medium coating → topcoat, the car body goes through dozens of processing techniques before going offline. Each treatment process must be equipped with a corresponding coating filtration system to remove dust impurities, oil and rust, to ensure the uniformity and excellence of the body coating effect. At the same time, the circulating filter liquid, improve the coating liquid and water efficiency, reduce operating costs. The pre-treatment of the coating is the basis of the automotive coating process. The goodness and the badness of the pre-treatment process are the key to determining the success of the entire body coating process.

The role and purpose of pre-spray treatment

In order to obtain high-quality coating effect and good anti-corrosion performance, the body must be surface treated before painting, including removing impurities such as oil, rust and scale, and necessary surface chemical treatment and conversion. Through the pre-treatment process, the adhesion and corrosion resistance of the body coating film can be improved, the protective effect of the coating can be fully exerted, and the service life of the coating can be prolonged.
