Analysis and countermeasures of common defects in paint film and painting of plastic parts

Plastic, which is mainly composed of a resin component, is formed into a certain shape under the action of a certain temperature and pressure, and then maintains a predetermined shape at room temperature. The polymer organic material has thermoplasticity and thermosetting properties. With the rapid development of plastic improvement and processing technology, the application of plastic in various industries is becoming more and more extensive. At the same time, the quality requirements for the application of plastic materials in different fields are also increasing. How to optimize the appearance of the plastic surface and enhance the life of the plastic? It is necessary to work hard on the surface of plastic parts and carry out coating treatment. Of course, due to different plastics, the composition and structure of their raw materials are also different, resulting in significant differences in surface properties. In order to meet the requirements of plastics in different fields, plastic surface treatment technologies and spraying materials have emerged as the times require. This paper mainly analyzes the coating process, surface treatment and common defects of plastic parts and proposes corresponding solutions.
