The project explores ways to implement environmentally friendly Plasma Electrolytic De-Painting (PEDP) technology for paint removal from military components. The program’s technical objectives are as follows:
During this program the project team will evaluate a novel PEDP technology to remove the paint using an environmentally friendly electrolyte in a very fast process that can meet the required production rate needs. In this process the military component or any part that needs to be de-painted is immersed in an electrolyte and high energy electrical impulse is applied resulting in a plasma discharge. In a few minutes all the paint is removed from the surface without affecting the underlying anodized layer or substrate material. The paint debris can be filtered from the electrolyte which is then re-useable.
Elimination of chemical strippers [methylene chloride (also known as dichloromethane or MeCl2)] and Plastic Media Blasting [(PMB), a dry abrasive blasting process, which uses plastic media pellets] will offer DoD these immediate and long-term cost, regulatory, and environmental, health, and safety benefits:
