How to solve the dust particles that appear during spraying

The appearance of dust particles during the coating process plays an important role in the coating quality of the product.

Reason for formation:

1) During spraying, dust falls onto the surface of the paint film from the spray booth, spraying tools, and air.

2) Dust accumulates on the surface during polishing.

3) The oil cylinder coating has deteriorated or been contaminated.

4) There is dust on the staff's clothes.

5) Plastic parts have static electricity and absorb dust.

6) Moving (walking) around the workpiece causes dust to rise.

7) The air pressure inside the grill is too low.

8) The filter cotton is clogged.

9) There is dust on the floor of the grill.

10) The walls of the grill are very dirty.

11) The ceiling cotton is not suitable.

12) The air ducts are very dirty.

13) There are fibers falling off the torn part of the masking paper.

Resolvent

1) Thoroughly clean the area around the spraying zone.

2) After polishing the paint film and putty, the dust must be blown off.

3) Before spraying, carefully wipe the surface to be coated with a dust cloth and store the dust cloth in a clean polyethylene (plastic bag).

4) Filter the coating with a copper mesh of 140-180 mesh.

5) Wear clean, fiber free, anti-static spray coating work clothes (nylon).

6) Treat with anti-static agent. Do not degrease plastic parts again thereafter.

7) Do not walk around freely in the grill.

8) Regularly check the pressure in the baking room.

9) Regularly replace the filter cotton.

10) Keep the baking room floor clean. Do not place any unnecessary items inside the grill.

11) Regularly clean the grill.

12) Use suitable ceiling cotton.

13) Use an old cloth to clean the 2m long air pipe under the spray gun. When spraying, do not let this pipe fall on the floor. After spraying, hang the air pipe.

14) Use high-quality masking paper to fold the torn edge inward and ensure that the smooth surface of the paper faces outward.

15) When spraying, the needle tip can be used to remove the dust mixed in the paint film. Small dust inside the dry coating can be removed by polishing treatment. If dust settles in the deep layer of the coating, the surface should be polished and re sprayed.
