Most of the domestic coating lines use electrostatic spraying, the coating utilization rate is basically controlled at 60%~80%, and a lot of paint mist is easily generated during the painting process. Most of them will form paint residue, and some will float in the air, and some will absorb. On the surface of the automatic spraying equipment and painting booth, or scattered on the surface of the painter's clothes hat, gloves, etc., eventually gather to form particles and pollute the body. Such particles will especially contaminate the sprayed wet film, forming particles that are difficult to handle, accounting for particles. More than 40% of the total amount is formed.

Effective measures:

(1) Set circulating water under the spray booth, and use the circulating wind to bring the paint mist to the water for treatment.

(2) Lay on the wall with anti-static plastic paper, and apply Vaseline glue, and replace it once a week.

(3) Automatic machine rotating cup, the part of the atomizer will accumulate under the action of static electricity for a long time, and will form paint slag on the surface, so it will be cleaned 2 times/shift and cleaned with special clean cloth. More silk.
