Research On Automobile Coating Process And Coating

As an important part of car production automobile painting has attracted more and more attention. Types of automobile coating and spraying way has an important effect on use of cars in the car body from corrosion, UV protection. With the development of automobile industry, automobile coating materials and coating technology has experienced from scratch, spraying transition from coarse to fine. And with the materials and innovative ideas, more and more new spraying method is adopted.Along the car spraying material and spraying technology development track, a detailed overview of the development situation of domestic and foreign automobile coating material and spraying technology has been done. Mainly in the following three aspects.(1) The automobile coating process is given in detail. The typical domestic and foreign automobile coating process were introduced in detail. For the general technological process are introduced. And the current advanced coating process, such as: no phosphating treatment, "the three wet" new technology, such as dry spray painting process are emphatically expounded. Through the introduction to traditional and advanced spray technology, as well as on the spraying process in China is pointed out the gap with the international advanced level(2) In view of the traditional "three coating two drying" spraying process, the improvement of the "three coating a baking" coating process. Will be the original need to dry into a two drying. Greatly reduce the energy consumption and pollution. And the "three coated one" spray process only need a set of drying equipment, not only save the money and improve the efficiency. The key to "three" to reduce the number of drying is "wet touch wet" process.(3) Compared with the traditional quality of new coating paint and related coating process in the working efficiency, energy saving and emission reduction and technology management, provides the reference for the automotive consumer. At the same time, in view of the development of new coatings and coating process characteristic prospects the development direction of automobile coating industry.
