Half of operators now use perc, survey says

摘要

Asked what solvent system or systems they use to clean clothing, only about half (50.5%) of drycleaners report that they now use perchloroethylene, according to the most recent Wire survey, marking a major shift in solvent usage. One-third (33.3%) use a high-flashpoint hydrocarbon system, and another 14.1% use a low-flash petroleum solvent. GreenEarth's D5 silicon solvent is the next-most-popular, with 11.1% of current users. Liquid CO_2, DrySolv and GreenJet's surfactant system each garnered 2.0% of users, and Solvair had 1.0%. No operators reported using Rynex' glycol ether system.
