一、概述电泳涂漆是电镀原理在涂漆上的应用。目前有阳极电泳涂漆和阴极电泳涂漆两种。阳极电泳涂漆时,在直流电场下,阴离子树脂(夹带颜料)移动到阳极,放出电子后沉积在工件上,经干燥后固化成膜。随着电泳过程不断进行,树脂沉积在工件上,固体份不断下降,通过新漆加入来补充,中和剂乙醇胺留在槽中积累,使pH值逐渐增高,最高
First, an overview of electrophoretic coating is the principle of plating in the application of paint. Currently there are two types of cathodic electrophoretic coating and cathodic electrophoretic coating. Anodic electrophoretic coating, the DC electric field, the anion resin (entrained pigment) moved to the anode, the release of electrons deposited on the workpiece, after drying and curing into a film. With the continuous electrophoretic process, the resin deposited on the workpiece, the solid fraction continues to decline, added by adding a new paint, ethanolamine neutralizer to stay in the tank accumulation, the pH gradually increased, the highest
