Study On The Color Difference Of Light Metal Paints For Vehicle

In the process of vehicle use, bruised accidents are inevitable, about how to repair and coating to make customer satisfaction, this is every car repair paint coating color maintenance engineers and technicians should consider problems, is engaged in auto painting the responsibility of the relevant colleges and universities teachers and researchers. Body color difference control, however, is a very complicated process, various factors affecting the final coating color difference, and the coating material and coating technology and coating equipment, construction is closely related to the factors such as environment, in the process of repair have no good control, a process is likely to produce color difference phenomenon, especially of light color metallic paint when maintenance is easier to produce. Therefore, it is necessary to study body of coating color difference control method and solve the technology of coating color, to enhance the maintenance enterprise’s technical level, can satisfy the demands of the customer for roof coating quality maintenance.The research, based on Liaoning Province College of Communications "car light metallic paint spraying defect of research" project, with light color metallic paint to repair car body painting color difference problem as the research target, the expert scoring method is used to induce the specific direction of research, through the enterprise information collection to test analysis summary to the construction verification process, work cycle for many times, finally found body light color metallic paint repair coating color difference of general solution. The main content of this paper include:1.The type and color control method of automobile coating, introduces the relevant theoretical knowledge of light metal paint coating color defect repair.2.The expert grading and testing of the color difference defect of the light coloured gold paint, the key and difficult points of the research are determinedby the enterprise investigation, and the defect reduction test in the laboratory is carried out.3.The color difference analysis of the car body repair and painting, the analysis of the test results, summed up the factors affecting the color of the film, and the development of standard coating repair process.4.The design and practical application of the transition spray technology,the design of the transition coating solution is very difficult to solve the problem of light color gold paint maintenance, and through the feedback of the results of the adjustment process to determine the best solution.
