Technical principle:
The basic principle of electrostatic spraying mainly relies on the electrostatic generator to generate a certain negative high voltage. The requirement of this negative high voltage is about 10KV. It uses corona discharge to promote the adsorption of colored pigments on the metal parts to be sprayed, while the The paint is supplied by a powder supply system and then delivered to the spray gun by means of compressed air, so a high-voltage electrostatic generator will be installed in front of the spray gun. A certain amount of dense electric charge will be generated around, and then the gun nozzle will spray powder, and the sprayed powder particles are all charged, because they are affected by electrostatic force, they will be directly adsorbed on the metal parts, and then carry out Heating melts the paint particles, which naturally cool and solidify, creating a hard coating film on the surface of the metal part.
