Plastic coating process has five main steps: 1 annealing: Plastic molding is easy to form internal stress, stress concentration easy to crack after coating. Annealing process or the entire surface can be processed to eliminate stress. Annealing is the ABS plastic molded parts to a heat distortion temperature, that is 60 ℃, oxyacetylene flame spraying equipment, insulation 2h. As a result of this process requires a lot of investment in equipment, flame spraying equipment, therefore, flame spraying equipment specifications, technical entire surface can be treated, that configuration can eliminate the stress of plastic parts solution at room temperature plastic surface for 15 ~ 20min treatment can be. Electrostatic spray equipment technology theory and the phenomenon of electrostatic spray processing technology occupies a central base and a dominant position in the process of spraying equipment, so that the plastic powder flame spraying equipment, in-depth understanding of electrostatic spray equipment during the phenomenon of electrostatic spraying equipment Equipment users and spraying equipment maker is very important. Spray equipment technology in the development process, the people have been so few problems to solve and work with: 1. How can I get a uniform and high quality film; 2. How to get as much time on the extraction rate; 3. How to overcome Faraday effect leaving the workpiece surface with a complex geometric shape are effectively coated cover; 4. How to implement complex workpiece spray; 5. How to achieve powder paint thinner to achieve the requirements of the car itself as a coating.
