General metal material electrostatic spray process as follows: pre-treatment Objective: To remove surface oil, dust, rust, and corrosion-resistant and able to generate a spray coating to increase adhesion "phosphate layer on the surface . " The main process steps: degreasing, rust, phosphate, passivation. After the pre-treatment of the workpiece surface is not only oil, rust, dust and electrostatic spray lawn fence, and original silver with a layer of coarse gray uniform and phosphate coating is not easily generate rust on surface gloss, both anti-rust and to increase the adhesion of spray layer. Related equipment: pre-treatment tank (tank made of concrete, equal to that pretreatment step number); related materials (chemicals): sulfuric acid, hydrochloric acid, soda ash (Na2CO3) electrostatic spray zinc steel handrails, acidic degreasers electrostatic spray, air conditioning guardrail electrostatic spray phosphating solution, the passivation liquid electrostatic spray process describes a typical powder coating process powder coating process is as follows: a piece → degreasing → washing → rust → washing → phosphate → washing → passivation The main factor → powder coating → curing → cooling → next item affect quality powder coating powder coating, the impact of factors in addition to the quality of spraying the surface pre-treatment quality is good or bad, there are spraying time, the form of gun, spray voltage , dusting the amount of powder conductivity, powder size, powder size, speed, powder and air mixture gradient.
