Electrostatic spray and traditional spray paint have advantages

Compared with the traditional spray technology, electrostatic spray technology (electrostatic spray molding) has significant advantages, such as no need for thinner, no pollution to the environment and no harm to human body; excellent appearance quality of coating, strong adhesion and mechanical strength; short curing time of spray construction; much higher corrosion resistance and wear resistance of coating; no need for primer; simple construction, low technical requirements for workers; cost It is lower than the spray painting process; some construction occasions have clearly proposed that the electrostatic spray molding process must be used; there will be no common flow phenomenon in the spray painting process during the electrostatic spray powder spraying process The process principle of electrostatic spraying is to charge the plastic powder through the high-voltage electrostatic equipment, and evenly absorb it on the surface of the processed workpiece under the action of the electric field, and then after high-temperature baking, the plastic particles will melt into a dense protective layer firmly attached to the surface of the workpiece The process flow of electrostatic spraying is pretreatment (oil removal, rust removal and phosphating); electrostatic spraying; high temperature curing (with reference to the required temperature of plastic powder, generally 160-210 ℃); furnace cooling
