Scientific Basis for Paint Stripping Mechanism for Methylene Chloride Based Paint Removers.

摘要

The objective of this project is to determine the depaint mechanisms of methylene chloride based paint removers. Two pillars of the technical approach used to achieve the objective are (1) a study that monitors the physical changes in the paints exposed to the paint removers and identifies their causes and (2) a spectroscopic study that leads to gain a fundamental understanding of the chemical interactions between the paints and the paint removers at the molecular level. The results from this project will help formulate a new class of paint removers. Once implemented, the process owners will realize advantages of the new paint removers such as (1) lower volatile organic compounds (VOC) emission, (2) less hazardous solid waste disposal, (3) compliance with environmental, safety, and occupational health (ESOH) regulations, (4) reduced process times, and (5) reduced corrosion-related repair time. As a result, the Department of Defense (DoD) will realize significant cost savings in the depaint and corrosion control operations.
