USING HYDROLYSIS AS A SAFE AND EFFECTIVE ALTERNATIVE TO CLEANING POLYMER FILTERS AND RELATED PARTS

摘要

Today's safety and environmental regulations have made it necessary to develop and alternative method of cleaning polymer filters and related extrusion parts contaminated with polymer. The replacement cost of filters and the need for longer life have driven this need as well. A new process for cleaning filters has been developed to meet these needs. This process involves hydrolysis of molten polymers, and has been proven to be an efficient, safe and inexpensive solution for cleaning filter elements and assembled filter housings. This paper will review the use of hydrolysis in comparison to other technologies currently in use.
