摘要

This study is to promote cleaner production using non-chlorinated alternative cleaners in parts cleaning of electroplating job shops. The approach describes the environmental and health effects associated with five chlorinated cleaning solvents through literature review, and develops an entirely systematic and comprehensive evaluation method to select non-chlorinated alternative cleaners.;The chlorinated solvents are environmentally unsafe and are detrimental to worker health and safety. As a result of these findings, government agencies have strictly regulated the production and use of these chlorinated solvents. These regulations, have been the driving force toward cleaner production using non-chlorinated alternative cleaners.;Six electroplating job shops were selected to quantify the various common substrate types to be cleaned and identify the common contaminant types. Eight compatible alternative cleaners were chosen from Surface Cleaning Laboratory data base of the Toxics Use Reduction Institute in the University of Massachusetts Lowell. The two most effective alternative cleaners were selected.;The results of cleaning effectiveness were compared for the variables in a WE vapor degreaser and in ultrasonic and low pressure spray units using the two alternative cleaners. The environmental and health hazards for TCE and the two alternative cleaners were quantified by P2OASYS. Economic analyses of each option was performed using the total cost assessment method.;This study ascertained that the most common substrate types are steel, copper, and aluminum. The most common contaminant types were metal working fluids and machining oils. TCE vapor degreaser removed almost 100% (ave. = 99.90%). The two alternative cleaners had cleaning efficiencies greater than 100%. The metal loss effect was stronger in alternative cleaner one (ave. = 106.80%) than alternative cleaner two (ave. = 101.80%). Metal loss was directly related to the cleaning method used.;The final hazard scores of P2OASYS showed that TCE is much more hazardous than the two alternative cleaners selected. This study found P2OASYS to have shortcomings in evaluating the potential hazards. Therefore, the scores determined by this study can be inaccurate to some unknown degree. A new method of P2OASYS was developed. The quantitative/objective data is no longer influenced by the qualitative/subjective data. The new method is most accurate when all data about each mixture as a whole is available.;This study also found that the use of non-chlorinated alternative cleaners is much more cost-effective than that of the chlorinated cleaning solvents. This study demonstrates that it is possible to develop alternative cleaning methods for electroplating job shops that are effective, safe and efficient. (Abstract shortened by UMI.).
