This is the fastest electrostatic powder coating is an important construction technology in the current development of powder coating. 1) The basic principle between the gun and the workpiece to form a high-voltage corona discharge electric field gas painting equipment, when the powder particles discharged from the spray gun through the discharge port area, then the complement of a large number of electronic, become negatively charged particles, Under the action of electrostatic attraction, is adsorbed onto the positively charged workpiece up. When the powder is attached to a certain thickness, "sex repulsion" effect occurs, can not be re-adsorbed powder, so that each part of the powder layer of uniform thickness, and then cured by heating the powder layer after baking leveling become uniform film layers. 2) powder coating process typical powder coating process is as follows: a piece → degreasing → washing → rust → washing → phosphate → washing → passivation → powder coating curing → cooling → → next item 3) on the powder The main factor of electrostatic powder coating spray quality, the impact of factors in addition to the quality of spraying the surface pre-treatment quality is good or bad, there are spraying time, in the form of spray gun, spray voltage, dusting amount, powder conductivity, particle size, powder particle size, the powder and air mixture velocity gradient. Powder room is one of the main equipment electrostatic powder coating. Maintain steady air flow is the powder room cleaning, providing a clean working environment for the operator. Control room spray painting equipment coal-dust content to below the explosive limit (generally set at 10g / m3). In addition, the powder room to be conducive to clean aluminum wheels coating equipment, powder coating equipment easily deposited in the house, in order to change the color of the powder, interior have enough light, in order to facilitate the coating work. An electrostatic spray gun, classification: gun can be classified according to their use of portable spray gun, fixed automatic spray gun, spray gun, etc. disc; press charged into the form of a gun inside and outside the charged gun live; their bodies in the form of diffusion can be divided into conflict gun, gun rally, secondary air gun, centrifugal spinning cup gun. 2, spraying efficiency: the charged form of spray gun spray mechanism is to improve the efficiency of a very critical factor. Generally speaking the core spray gun and equipment is the charging system. On the market, a corona spray gun with a substantial proportion, this is because the use of high-voltage corona discharge manner powder charge has the biggest advantage is that all current types of spraying can be a thermosetting powder coating, and can get very good results. The advantage is mainly manifested in excellent stability, the extraction rate and speed on the powder.
