Dusting powder coating process is also known as, is a new coating process developed rapidly in recent decades, the raw material used is plastic powder. As early as in the 1940s, some countries began to research experiments, but progress is slow. 1954 Germany James polyethylene shell with a fluidized bed coating successful spraying equipment, after 1962 Semmes French invented powder electrostatic spraying, powder coating production began formally adopted in recent years due to national attention to environmental protection, water and air pollution-powder coating equipment, has been developing rapidly. Using electrostatic spray equipment to the surface of the powder coating to the workpiece, under the electrostatic effect, the powder will be uniformly adsorbed on the surface, forming a powder coating; powder coating through high temperature baking leveling curing into effect different 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 the powder coating, spray equipment before the bridge is not properly handled, resulting 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 Iron spraying equipment, 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 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.
