Plastic spraying process introduction

1. Annealing: easy to form internal stress when plastic molding, easy to crack after stress concentration. Annealing or entire surface treatment can be used to eliminate stress. The annealing treatment is to heat the ABS plastic moldings to a temperature below the heat distortion temperature, ie, 60° C., for 2 hours. Since this type of process requires a large amount of equipment investment, the entire surface treatment technique can be adopted, that is, the solution that can eliminate the internal stress of the plastic part can be treated at the room temperature for 15 to 20 minutes on the surface of the plastic part.
2. Degreasing: The surface of plastic parts is often stained with oil, hand sweat, and release agents, which can degrade paint adhesion and cause cracking, blistering, and shedding of the coating. Degreasing should be done before painting. The plastic parts are usually cleaned with gasoline or alcohol, and then after chemical degreasing chemical degreasing, the residual lye shall be thoroughly cleaned on the surface of the workpiece, and finally cleaned with pure water, dried or dried.
3. Electrostatic removal and dust removal: Plastic products are insulators, and the surface resistance is generally about 1013Ω, which is prone to static electricity. After being charged, it is easy to absorb fine dust in the air and adhere to the surface. It is very difficult to remove the dust adsorbed by static electricity by the general air blowing method, and the effect of high-voltage ionized air flow at the same time of removing electricity and dust is better.
4. Spraying: The thickness of the plastic coating is 15~20μm. It usually takes 2~3 shots to finish. After a spray, dry it for 15 minutes and then perform a second spray. Bright surfaces must also be sprayed with clear paint. The coated article has essentially no effect on the flame retardant properties.
5. Drying: After coating, it can be dried at room temperature or baked at 60°C for 30 minutes.
