Summary
As part of an Environmentally Conscious Manufacturing (ECM) Program, a study was conducted at Sandia National Laboratories to identify an alternative cleaning process that would effectively replace trichloroethylene (TCE) for cleaning mechanical piece parts of Switch Tube assemblies. Eight aqueous alkaline cleaners, as well as an isopropyl alcohol and isopropyl alcohol/Cyclohexane cleaning process, were studied as potential replacements. Cleaning efficacy, materials compatibility, etch rate and corrosion studies were conducted and used to screen potential candidates. Cleaning efficacy was determined using visual examination, goniometer/contact angle measurements, Auger electron spectroscopy, X-ray Photoelectron spectroscopy and an evaporative rate analysis technique known as MESERAN Surface Analysis. Several cleaners were identified as potential replacements for TCE based solely on the cleaning efficacy results. Some of the cleaners, however, left undesirable residues studies were completed, Brulin 815GD (an aqueous alkaline cleaner) was selected as the replacement for TCE.
