粉末涂装方法很多。如:流化床,静电流化床、静电振荡(BPE法),静电机械振荡、静电云雾室、静电喷涂等等。目前主要以静电喷涂为主,其次是流化床。静电喷涂系利用高频高压发生器产生负高压(-40—-90KV),通过枪内电极放电,当粉粒经过此放电区便捕集一定量的负电荷,在风力和静电场力的作用下,带负电粉粒到达工件并在工件上形成粉层。粉层达到
There are many ways of powder coating. Such as: fluidized bed, electrostatic fluidized bed, electrostatic vibration (BPE method), electrostatic mechanical oscillation, electrostatic cloud chamber, electrostatic spraying and so on. Currently mainly electrostatic spraying, followed by the fluidized bed. Electrostatic spraying using high-frequency high-voltage generator to produce negative high pressure (-40--90KV), through the gun electrode discharge, when the particles through this discharge area will capture a certain amount of negative charge, the role of wind and electrostatic force Next, the negative particles reach the workpiece and form a powder layer on the workpiece. Powder layer reached
