Evaporation of water will make the surface to be coated when the surface treatment 3. After remaining water, the remaining water has to be coated in a film produced by baking after painting shrinkage, so when you want to adjust the surface treatment after washing The drying temperature and time, so that was painted in the air in time to escape the pores and coating heal quickly. 4. When replacing HVOF coating species, equipment cleaning is not complete, resulting mix of old and new paint color spray, mutual interference, easy to produce shrinkage spray paint, so when changing coating species, be sure to spray gun for powder tank, powder feeding pipes, powder room and other equipment clean. Also used in coating paint line when compressed air contains oil, water; severe damp paint; coating of dust and other environmental acrobatics into the powder room, the oven will cause shrinkage and other ills of life and life painting, so to ensure a clean environment is important spraying. 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 hollow spray, in-depth understanding of electrostatic spray equipment during the phenomenon of electrostatic spraying equipment and user equipment 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.
