静电喷塑的工艺原理:

The technological principle of electrostatic spraying:

是利用电晕放电现象使粉末 涂料 吸附在工件上的。其过程是这样的：粉末涂料由供粉系统借 压缩空气 气体送入 喷枪 ，在喷枪前端加有高压静电发生器产生的高压，由于电晕放电，在其附近产生密集的电荷，粉末由枪嘴喷出时，形成带电涂料粒子，它受静电力的作用，被吸到与其极性相反的工件上去，随着喷上的粉末增多，电荷积聚也越多，当达到一定厚度时，由于产生静电排斥作用，便不继续吸附，从而使整个工件获得一定厚度的粉末涂层，然后经过热使粉末熔融、流平、固化，即在 工件表面 形成坚硬的 涂膜 。

It is the use of corona discharge to make powder coatings adsorbed on the workpiece. The process is this: powder coating by powder supply system by compressed air into the gas gun, a high voltage of the high-voltage electrostatic generator in the gun front, due to the corona discharge, producing a dense charge in its vicinity by powder spout gun, the formation of charged coating particles, it is affected by the electrostatic force, being sucked with the opposite polarity to the workpiece, with the spray powder increased, the charge accumulation is more also, when reaches a certain thickness, due to electrostatic repulsion, will not continue to adsorption, the powder coating so that the workpiece thickness, and then through the heat of the powder melting, leveling, curing, forming the hard coating on the surface of the workpiece.
