Aluminum spraying generally after three-coat two baking:
Spraying aluminum three-coat two baking means: start when three gun spray, primed first, second coloring paint (PVDF or polyester paint), third protection coating paint (varnish), two grilled refers to aluminum after three and then painted twice baked bake. But now the spray line is basically: three-coat one bake, two coat one bake. .
Aluminum profiles in the process must be carried out before spraying chemical cleaning and etching, removing the surface adhesion of oil, natural oxide film and the dust and other pollutants, the aluminum alloy substrate exposed, to form a uniform surface activation, which is to ensure chrome key film quality and the quality of spraying of salt conversion.
Spraying aluminum profiles with excellent corrosion resistance and weather resistance, durable, good decorative appearance, the production process is simpler than the anodic oxidation, environmental protection and other safety features in construction, decoration, transportation and other industries are widely used.
Aluminum spray is sprayed on the surface of an aluminum plate of various colors fluorocarbon (or polyester paint), high temperature baking, curing, also known as aluminum paint. It can be used for building facades, interior decoration, interior ceiling and so on.
