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, 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, the electrostatic attraction under the action, is adsorbed to the positively charged workpiece up. When the powder is attached to a certain thickness, "sex repulsion" effect occurs, you can not re-adsorption powder, so that each part of the powder layer thickness uniformity of paint coating equipment, and then cured after heating baking powder layer leveling a homogeneous film. 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. Electrophoresis surface treatment characteristics: electrophoretic coating film has plump, uniform, smooth, smooth advantages painting equipment, electrophoresis coating hardness, adhesion, corrosion resistance, impact resistance, permeability was significantly superior to other coating process . (1) the use of water-soluble paint, with water as the dissolution medium, saving a large amount of organic solvent, greatly reducing air pollution and environmental hazards, safety and health, while avoiding the risk of fire; (2) high efficiency gas paint coating equipment little paint loss, paint utilization up to 90% to 95%; uniform (3) film thickness, adhesion, good coating quality, various parts of the workpiece, such as the inner, dents, weld, etc. can be obtained uniform, smooth film, other coating methods to solve the complex shape of the workpiece coating problems; high (4) production efficiency, the construction can be automated continuous production, greatly improving the efficiency of labor; (5) device complexity, high investment costs , power consumption, higher temperatures required by its drying curing, paint, painting the management of complex construction strict conditions, and the need for wastewater treatment; (6) can only use water-soluble paint, not in the coating process change the color of coal-fired painting equipment, paint storage stability for too long and difficult to control. (7) electrophoresis coating equipment complexity, high-tech production for fixed color.
