喷漆前对塑料零件进行大规模工业清洗包括三个独立的操作；动力清洗、漂洗和干燥。动力清洗采用机械和化学清洗，以去除妨碍油漆质量的大量内部和外部污染物。清洁完成后，可通过冲洗去除清洁剂和悬浮污染物，冲洗可包括几个步骤。最后，一旦污染物被纯水置换，必须对零件进行干燥，以确保喷漆室收到干燥零件。干燥操作包括送风、排水和烘箱干燥。本文的重点是对清洗过程的描述。应特别注意使用不同类型的清洗辅助化学品，以帮助清洗塑料零件。

LARGE-SCALE INDUSTRIAL CLEANING OF PLASTIC PARTS PRIOR TO PAINTING CONSISTS OF THREE SEPARATE OPERATIONS; POWER WASHING, RINSING, AND DRYING. POWER WASHING EMPLOYS MECHANICAL AND CHEMICAL CLEANING FOR THE REMOVAL OF A HOST OF INTERNAL AND EXTERNAL CONTAMINANTS WHICH IMPEDE QUALITY PAINT RESULTS. ONCE CLEANING HAS BEEN ACCOMPLISHED, REMOVAL OF THE CLEANER AND SUSPENDED CONTAMINANTS IS ACHIEVED BY RINSING WHICH MAY CONSIST OF SEVERAL STEPS. FINALLY, ONCE THE CONTAMINANTS HAVE BEEN DISPLACED BY PURE WATER, PARTS MUST BE DRIED TO ASSURE THAT A DRY PART IS RECEIVED AT THE PAINT BOOTH. THE DRYING OPERATION CONSISTS OF COMBINATIONS OF AIR BLOWOFF, DRAINING, AND OVEN DRYING. THE FOCUS OF THIS PAPER IS A DESCRIPTION OF THE RINSING PROCESS. PARTICULAR ATTENTION WILL BE PAID TO THE USE OF DIFFERENT TYPES OF RINSE AID CHEMICALS TO ASSIST IN THE RINSING OF PLASTIC PARTS.
