Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of coating film. Electrostatic powder spraying equipment The sprayed powder will be very uniformly adsorbed on the surface of the workpiece to form a powdery coating. The powdered coating will be leveled and cured after high temperature baking. The selection of different powder coatings will become the final coating with different effects. The spraying effect is in the mechanical strength. , adhesion, corrosion resistance, aging resistance, etc. are better than the painting process.
Good powder coating, good powder is easy to spray, spray 1-3 guns to cover the substrate, less secondary powder, high work efficiency. Poor paint is not easy to powder, spray 3-5 guns to remove The substrate is covered, the secondary recovery powder is more, and the work efficiency is low. The difference method produces less products at the same time, and the secondary recovery powder is more, which increases the burden of the operator and the work efficiency is low.
Electrostatic powder coatings adhere to the metal surface following the generation of static electricity. Therefore, their wear resistance and adhesion will be very high, and their service life will be longer than that of ordinary coatings. In the process of contact, separation and electron transfer between different objects, there are more complicated mechanisms than those described above. Objects lose electrons, so that electrostatic reactions occur between them, and we see the so-called static electricity.
The atoms of object A have the same number of protons and electrons, and the same is true of object B. Both objects are electrically neutral. It's just that some electrification processes are extremely weak, and the electrostatic charges generated by some processes are neutralized or transferred. There is no electrostatic electrification phenomenon on the macroscopic level. When two objects come into contact and then separate, the charge is transferred from the surface of one object to the surface of the other object.
