Surface Treatment Technology of Leecheer Prototype
Currently, air spraying is comparatively extensive spraying technology in painting craft project.
Air spraying makes use of compressed air which form negative pressure when flow spray gun.
The paint vehicle is absorbed form sucker by negative pressure, and is sprayed out by spray gun
as painting mists. When painting, painting mists become even film on the surface of prototype.
Air spraying can paint even film, and smear layers are very smooth. It can spray the hidden parts
such as gaps and unevenness. The utilization rate of dope is low in this way, which is about 50 to
60 percent. There are some effect after painting on plastic prototype.
1. Spray painting can cover the deficiency of prototype surface.
2. The plastic itself is difficult to color. Spray painting can paint many kinds of color on plastic.
3. Spray painting improves the electrostatic properties of plastic, which can reduce dusty-adsorption.
4. Spray painting strengthens hardness and mar-resistance of plastic.
5. Spray painting improves weather resistance of plastic.
6. Spray painting can adjust the gloss of plastic surface.
7. Some special lacker such as sand paint, fluff paint can achieve effect of good appearance
and hand feeling.
