电泳表面处理设备 ELECTROPHORESIS SURFACE TREATMENT EQUIPMENT
极电泳涂料所含的树脂带有碱性基团,经酸中和后成盐而溶于水。通直流电后,酸根负离子向阳极移动,树脂离子及其包裹的颜料粒子带正电荷向阴极移动,并沉积在阴极上,这就是电泳涂装的基本原理(俗称镀漆)。电泳涂装是一个很复杂的电化学反应,一般认为至少有电泳、电沉积、电解、电渗这四种作用同时发生。广泛用于汽车,高铁等行业。
The resin contained in the cathodic electrophoretic coating has basic groups,which form a salt after acid neutralization and dissolve in water. After the direct current is applied, the acid radical negative ions move to the anode and the resin ions and the pigment particles wrapped in it move to the cathode with positive charges and are deposited on the cathode. This is the basic principle of electrophoretic coating (commonly known as paint coating) Electrophoresis coating is a very complex electrochemical reaction. It is generally believed that at least four effects of electrophoresis, electrodeposition,electrolysis, and electroosmosis occur simultaneously. It is widely used in automobiles, high-speed rail and other industries.
