Coating process: electrostatic spraying process of powder coating

Core tip: electrostatic spraying principle of powder coating: the powder coating is adsorbed on the workpiece by corona discharge The process is as follows: the powder coating is sent to the spray gun by the powder supply system through compressed air, and the high voltage generated by the high voltage electrostatic generator is added at the front of the spray gun Due to corona discharge, dense charges are generated near the spray gun When the powder is ejected from the gun nozzle, charged coating particles are formed Under the effect of electrostatic power, it is sucked to the workpiece with the opposite polarity, along with the powder sprayed When it reaches a certain thickness, it will generate electrostatic repulsion Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: electrostatic spraying principle of powder coating: it uses corona discharge phenomenon to make powder coating adsorb on workpiece The process is as follows: the powder coating is sent to the spray gun by the powder supply system through compressed air, and the high voltage generated by the high voltage electrostatic generator is added at the front of the spray gun Due to corona discharge, dense charges are generated near the spray gun When the powder is ejected from the gun nozzle, charged coating particles are formed Under the effect of electrostatic power, it is sucked to the workpiece with the opposite polarity, along with the powder sprayed When it reaches a certain thickness, it will not continue to absorb due to electrostatic repulsion, so that the whole workpiece can obtain a certain thickness of powder coating, and then the powder is melted, leveled and solidified by heat, that is to say, a hard film is formed on the surface of the workpiece Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
