The difference between roller coating and spraying

The characteristics of roller coating
1, high-speed automation work, coating speed, high production efficiency, production speed is generally about 100mm/min, up to 244m/min
2, no paint fog, no paint fog fly Splashing, coating with an efficiency of nearly 100%
3, low viscosity and high viscosity coatings, can be carried out 3-5 m film to 300-500 m thickness of various film thickness coating. Can be more accurate control of the thickness of the paint film, and the thickness is uniform
4, front and back can be applied at the same time

and spraying differences
After the roller coating is a roll of aluminum plate with lacquer layer,
the
. Can be directly processed into colored aluminum falling water products, spraying is in the aluminum plate bent into eaves and other molding, and then paint with a spray gun.
2. Rollers are coated with back coating, spray is not
coating: roller coating is 3 coatings: the surface coating is a color-showing coating, the bottom coating is between the surface coating and aluminum plate, enhance the firmness of the surface and aluminum plate bonding, the back coating is aluminum plate back anti-corrosion coating, enhance the corrosion resistance of the color coating plate. Spray only one layer of hand-made surface.
3. Baking: Rolls are coated with two bakes (commonly known as three and two bakes) and sprayed as one bake.
