Research Topics


Chlorofluorocarbon (CFC) solvents have been used effectively for many years to clean precision parts generated from military and industrial manufacturing operations, and environmentally acceptable, cost effective solvent alternatives are being sought. In this Phase II project, CF Technologies, Inc., (CF TECH) will manufacture and test a prototype precision cleaning machine based on the use of CO2 as the primary cleaning solvent. The cleaning system will be used to remove oils, greases and particulates from guidance system components and hardware, computer disc drives, silicon wafers, and a wide variety of other precision parts generated from military and commercial manufacturing operations. The use of CO2 as the cleaning solvent will allow for an environmentally acceptable, commercially viable process that can be safely applied to a broad range of precision cleaning operations. The project will consist of: (1) fabrication and assembly of a skid mounted, transportable precision cleaning system; (2) an experimental program to quantify the removal of particulates using two CO2-based cleaning fuctions demonstrated during Phase I; and (3), prototype precision cleaning demonstrations performed at CF TECH and at selected DoD and commercial manufacturing facilities.
