Finding salvation from the 13 deadly sins of pretreatment—part II
This article is the second in a four-part series that lists offenses committed by operators of pretreatment systems. Part I, which was published in April, dealt with two of the gravest errors finishers make - improperly designing the pretreatment process and losing control of manufacturing.
In this part, the article covers four sins: the use of low-technology chemicals, lack of preventive maintenance, high turnover in operators, and lack of continuous education. The article goes into detail about pretreatment chemicals, including cleaners, iron phosphates, seal rinses, and additives.
