Metal surface coating baking spray equipment

Process spray equipment Published: 2012-04-26 Process spray device: A is coated on the surface before treatment: mainly degreasing, descaling, its methods and coating liquid paint pretreatment same. Two putty: the extent of the workpiece defect Scraping conductive putty, dried and sanded smooth, the next step can be carried out. Three Preheat: generally without preheating. If a thicker coating is requested, the workpiece may be preheated to 180 ~ 200 ℃, which can increase the coating thickness. Four spraying: electrostatic interaction under high pressure, the spray gun then negative, grounding of the workpiece (anode) constitute a loop, by means of compressed air from the spray gun powder that is a negative charge, according to the principle that opposites attract sprayed onto the workpiece. Five high-temperature curing: After spraying the workpiece, into the heated drying room 180 ~ 200 ℃, and the powder is cured. Six Cleanup: After curing the coating, remove the protective material, Shuhei glitches. Seven test: Check the workpiece coating, where the tainted spray, bumps, needle bubbles and other defects, should rework spray. Eight defect treatment: the workpiece is detected leakage spray, pinholes, bumps, bubbles and other defects, rework or re-spray.
