Powder spraying is the powder spraying equipment (electrostatic spraying machine) to spray the powder coating powder to the surface of the workpiece. Under the electrostatic action, the powder will be evenly adsorbed on the surface of the workpiece, forming a powdery coating; powder coating after high temperature baking leveling curing, into different effects (different kinds of powder coating powder effect) the final coating; the spraying effect of powder spraying is superior to the painting process in mechanical strength, adhesion, corrosion resistance and aging resistance, and the cost is also under the same effect of painting.
The service life of powder sprayed aluminum profile can reach 30 years under normal conditions.
Surface, paint leveling is better, powder will have a little orange peel, but the advantages of powder than paint, such as protective, non-toxic, chemical resistance is good.
Identify baking paint and spray paint:
Process:
Paint: on the substrate three times primer, four times paint, each time paint, are sent to the dust-free temperature baking room, baking.
Spray paint: grind on the substrate, spray paint on it, and let dry.
Paint film: hand touch the four edges and corners of the paint door, whether smooth, voucher; observe the color of edges and corners, whether the same as the color of the door panel.
Paint: smooth edges and corners, the same color.
It proves that the film is uniform and the color is full.
Spray paint: rough edges and corners, the color is lighter than the door.
It proves that the film is not uniform and the color is not full:
Grain: Compare the light to see whether there is an orange peel phenomenon on the surface of the painted door panel.
Baking paint: door surface smooth, no grain, orange peel phenomenon.
Spray paint: the door surface has grain, not smooth, orange peel phenomenon.
Surface: Touch the surface of the door with the hand paint, whether there are dust particles, bubbles.
Paint: the surface of the door panel is flat and smooth.
Spray paint: there are particles on the surface of the door, not smooth, and there is a strange feeling to the touch.
Wear resistance: Hit with a hard object.
Baking paint: no abnormal situation, no damage to paint film.
Spray paint: there are cracks, serious paint film off, white skin off.
