自泳涂装与电泳涂装区别  自泳涂装工艺是近几年在电泳涂装基础上而发展的新型涂装工艺，两者之间最主要的区别就是自泳不需通电，利用化学原理涂料产生电位差涂膜在工件上，而电泳则是在通电条件下产生电位差，涂膜在工件上。从理论而言，自泳涂装节省了电能，优于电泳，但在近几年市场推广方面而言，美国BBG公司，日本关西公司在自泳工艺推广市场方面还不多，都处于实验阶段，而电泳涂装在中国大陆遍及广泛，是非常成熟工艺，汽车涂装90%以上都采用了电泳涂装工艺。 电泳涂装具有以下特点：（1）涂装工艺容易实现机械化和自动化，不仅减轻了劳动强度，而且还大幅度地提高了劳动生产率。据某汽车制造厂资料统计，汽车底漆由原来浸漆改为电泳涂装后，其工作效率提高了45%。（2）电
