How to spray paint plastic?
Construction conditions

Spraying construction temperature is (25 5)℃. The construction relative humidity is not more than 80%. When the humidity is too high, add Cha- 13 or F- 1 moistureproof agent to the coating to prevent the coating from turning white.

Introduction of spraying construction conditions and technology of plastic parts

procedure

1, brush (brush, roller and other tools).

2. Roll coating.

3. Air spraying (spray gun plus compressed air).

4. Immersion is impossible (immerse the workpiece in a paint tank filled with paint and dip it in paint).

5. Electrostatic spraying.

6. Electrophoretic spraying.

7. High pressure airless spraying.

Surface treatment of plastic parts;

1. Thinner is usually used to clean the surface of plastic parts and remove oil chemically, so as to eliminate oil stains, dust and other chemicals in the production process of plastic parts and increase the adhesion of the substrate.

2. Because plastic parts are prone to generate static electricity, and static electricity will attract some dust to fall on the substrate, so it is difficult to remove. Therefore, anti-static treatment should be carried out on plastic parts, and high-pressure ionic air is generally used to remove the static electricity of plastic parts.
