Automated Aqueous Rotary Washer for the Metal Finishing Industry. TechnologyEvaluation Report

摘要

Product quality, waste reduction, and economic issues involved in the use of anautomated aqueous rotary washer in the metal finishing industry were evaluated in the study. The automated washer can be used for most metal parts that would ordinarily be cleaned by vapor degreasing, hand-aqueous washing, or alkaline tumbling. The automated washer had good potential to reduce waste, was economically viable, produced good product quality, and also avoided the vapor degreaser's use of perchlorethylene. When compared with hand-aqueous washing and alkaline tumbling, the automated washer used less chemicals. The payback period was about 7 years.
