The advantages of powder spraying are compared with the traditional spraying process, and some conclusions are drawn. The advantages of powder spraying are as follows:
① high paint utilization rate: up to 95%, the powder can be reused many times after recovery.
② high yield: it can be reapplied before curing. There are two kinds of powder spraying processes: electrostatic powder spraying and plastic dipping.
③ good coating performance: the thickness of one-time coating can reach 50-80 μ m, and its adhesion, corrosion resistance and other comprehensive indicators are better than the paint process.
④ energy saving: about 30% energy saving.
less pollution: no volatile organic solvent (no toluene, xylene and other harmful gases in the paint).
⑥ high efficiency: due to the one-time film forming process, the productivity can be increased by 30-40%.
Powder coating itself is a new
type of solvent-free 100% solid powder coating, which has the advantages of solvent-free and pollution-free. It has been widely used in modern architecture, home decoration and other fields.
