Anti-corrosion of automobile body (including commonly used protection methods, process, etc.)
The quality of the coating is good and bad is the result of the combination of the three elements of the coating, in which the correct selection of the coating process is also an important aspect of the impact of coating quality. The choice of the so-called coating process in a sense is the choice of coating methods, different coating methods for different conditions of painting, so choose the right coating method is very important. So far, the coating method is mainly dip coating, spraying, brushing, roller coating, electrophoresis coating, scratch coating, electrostatic spraying, rubbing and other 8 kinds, including electrophoretic coating, spraying, electrostatic spraying and scraping in the car Painting more applications.
The basic method of car body corrosion is painted with a car body.
Anticorrosion process With the increase in the number of years and mileage, car parts of the corrosion will gradually intensify. Automotive corrosion will not only damage the appearance of the car, but also a direct impact on the quality and service life of the vehicle. In this paper, from the analysis of the factors and characteristics of automobile corrosion, through the analysis of the corrosion characteristics of various parts of the body, from the body selection, paint selection and production maintenance and daily use of automotive anti-corrosion technology considerations, and as a basis, The latest anti-corrosion technology development and application, analysis of China's current stage of the automotive industry for anti-corrosion technology. Today, the main components of the car body is still the main metal materials, inevitably there are a variety of corrosion problems. Application of new anti-corrosion technology, not only can improve the appearance of the car quality, improve the appearance of the car performance, more importantly, can also improve the inherent quality of the car to extend the life of the car, improve the car grade. Domestic auto companies common anti-corrosion process is, respectively, on the chassis frame and body for anti-corrosion treatment, and then the two assembled into a vehicle. Among them, the frame after welding need to pickling, washing, degreasing, phosphating and other treatment, and then spray the car chassis anti-rust paint.
