General Rinses 冲洗概述

Rinsing performed after electrocoating removes the thin layer of paint (the cream coat) which adheres to the deposited electrocoat film. Minor amounts of paint left on the deposited surface will cause defects. Bodies should be rinsed as soon as possible after they emerge from the paint tank and never later than one minute after that point.

电泳后冲洗可除去电泳漆膜表面附着的一薄层浮漆。电泳表面带有少量浮漆会引起漆膜缺陷，在车身露出电泳槽后要尽快冲洗，不能长于1分钟。

Highly efficient closed loop and gravity return rinse systems are necessary (see Figure 13). These systems use ultrafiltrate in the final stage and overflow each stage back to the paint tank where paint solids are recovered. Five stages of ultrafiltrate rinsing and two stages of DI water rinsing work well, configured as follows:

高效率的“闭路”，“重力回流”冲洗系统是必要的（见图16），这些系统是在最后一道工序用新鲜超滤液，随工序向前溢流返回电泳槽，以回收漆液固体份，此系统以五道超滤液冲洗加二道去离子水冲洗较好，编排如下：

Over Tank Rinse: Single or Double Header

槽上冲洗单排或双排喷管

Recirculated Rinse 1: 30-45 Seconds

第一道循环超滤液冲洗： 30-45 秒

Dip Rinse: Complete Immersion

超滤液浸洗：全浸没

Recirculated Rinse 2: 30-45 Seconds

第二道循环超滤液冲洗 30-45秒

Fresh Ultrafiltrate: Single or Double Header

新鲜超滤液冲洗单排或双排喷管

Drain Area: Minimum of 60 Seconds

沥液区最少60秒

Recirculated DI Rinse: 30-45 Seconds Fresh

循环去离子说： 30-45秒

Virgin DI Rinse: Single or Double Header

新鲜去离子水单排或双排去离子水

Drain Time Between Rinses: 1 Minute

两道去离子水冲洗沥液时间：1分钟

All rinse tanks should be provided with good drainage so that cleaning will be effective. Acceptable materials of construction include coated steel tanks and stainless steel piping for rinses. Rinse walls, ceilings, and sanitary shields should be made of stainless or aluminized steel.
