电泳涂装培训手册（一）、电泳涂装的进展概况1809年俄国科学家列斯第一发觉了胶体粒子在电场作用下能产生电泳的现象。

但由于当时缺少良好的水溶性树脂，因此在工业上一直没有得到广泛的应用。

直到1960年由英国的卜内门与里兰公司共同研制成功阳极电泳漆与涂装工艺。

美国福特汽车公司早在1950年即开始从事电泳漆的研究，但直到1961年在美国PPG（匹茨堡平板玻璃公司）涂料分公司的配合下才建立了一条电泳涂装汽车车轮的试验生产线。

电泳技术人员培训初级资料目录1、电泳涂装概念及优点--------------------------------------------------------- 22、电泳涂装的机理及特性- --------------------------------------------------------- 3～43、电泳涂装工艺流程图---------------------------------------------------------------- 54、槽液特性值-------------------------------------------------------------------------------- 5～65、电泳涂装线设备--------------------------------------------------------------------------- 76、电泳涂装线操作要点-------------------------------------------------------------------- 81、电泳涂装1、何谓电泳涂装？被涂物浸渍于电泳涂料(水性)中，被涂物与电极间通以直流电，由于电场作用得到涂膜的涂装方法，叫做电泳涂装.2、特点1）尽管复杂形状的被涂物也可得到均一涂膜（膜厚）的涂装2）防锈性优良3）泳透性良好，构造物夹合处4）易于自动化（节省人力）5）作业线保养容易补给作业简单，无需特别补给装置酸浓度管理因隔膜方式所以容易6）涂装作业性良好（缺陷：流漆，针孔等涂装异常较少）7）经济实惠因具有UF回收装置涂料回收率极高（90%以上）8）低公害溶剂含有量较少，故空气污染少9）因系水性涂料没有火灾顾虑2、电泳涂装的机理及其特性电泳涂装分为电解，电泳，电沉积，电渗四种电化学物理过程。

一、电解任何一种导电液体在通电时都产生分解的现象称为电解。
