Electrostatic powder coating spray equipment to the surface of the workpiece, in electrostatic powder evenly adsorbed on the surface, forming a powder coating; powdery coating after high temperature baking spray leveling curing fire doors equipment into the effect of varying the final coating; spray painting process is better than in the mechanical strength, adhesion, corrosion resistance, anti-aging and so on. One. Surface preparation. Pre-treatment process quality directly affects the quality of fence powder coating spray equipment, pre-treatment is not good, causing the coating easy to fall off, bubbling phenomenon. Therefore, the first task must be stressed. (1) can be used for sheet metal stampings chemical pre-treatment method. Ie: go to rust oil → → washing → phosphate (or purified) and so on. Most surface rust or thicker workpieces, using sandblasting, shot blasting and other mechanical methods to rust, but after a mechanical descaling should ensure that the workpiece surface clean and free of dirt. (2) putty. Scraping the workpiece defect extent conductive putty, sanded smooth after drying, you can be the next procedure. (3) protection (also known as shield cover). If some parts of the workpiece does not require a coating of aluminum spray equipment before preheating can be covered up to protect glue, etc., in order to avoid the spray paint. (4) to warm up. Generally do not need to warm up. If a thicker coating layer is required, the workpiece can be preheated to 100 ~ 160 ℃, which can increase the coating thickness. Powder coating does not generate volatile organic compounds due to avoid waste due to evaporation to the atmosphere generated, compared with liquid coatings, energy costs are significantly reduced. Electrostatic spraying equipment you can get a thick coating, spray coating equipment need not be repetitive, do not hit the primer coating operations faster than the speed of the same thickness, and high efficiency. Painting equipment does not need the rest time, space saving device. In addition, the powder coating baking time is shorter than the liquid coating, it can greatly reduce the fuel consumption of energy, shorten painting line, increase production and productivity.
