Disadvantages: rough

cause
①The spraying distance is long, the air pressure is large, the spray gun caliber is small, the solvent has volatilized when the coating reaches the surface, and the coating can not level.
②The coated surface is not cleaned up.
③The paint and thinner are not matched, and the dissolving power is not enough.
④The fineness of the material in the paint is not enough.
⑤The spray gun has large caliber and low air pressure, so the paint is not atomized well.
⑥ The construction environment is not clean and the room is dusty.
⑦The filter screen is empty, and the paint crusts and the broken pieces are mixed.
⑧The spraying tools are not clean.
⑨The spraying is too thin and there is no leveling room.
⑩The paint has expired and deteriorated, and the resin and pigment will precipitate out, causing the phenomenon of reverse roughness.

Solution
① Adjust the reasonable construction parameters according to the requirements of the spraying process.
② Deal with dust and impurities on the surface of the coated object.
③Select the matching thinner of the coating according to the process requirements.
④Select the paint with qualified fineness requirements.
⑤Control the spray gun distance, and the spray gun caliber should not be too large.
⑥ Pay attention to environmental hygiene.
⑦Be careful to filter the paint, and the topcoat filter should be about 200 mesh.
⑧ Clean spray tools and pay attention to maintenance.
⑨Each coating should maintain a leveling effect.
⑩Pay attention to check the production date of the paint.
