Trichloroethane과 Trichlorotrifluoroethane의 대체세정제에 대한 세정력 평가에 관한 연구

A Study on the Cleaning Efficiency Valuation of Alternatives Cleaning Agent for Trichloroethane & Trichlorotrifluoroethane

Many alternatives to Trichlorothane & Trichlorotrifluoroethane mainly used as cleaning solvent for industrial parts are developed and commercialized because the solvent is scheduled to phaseout after 1996. Considering there are many kinds of parts and contaminants in all parts cleaning, It is essential to investigating the characteristics and performance of the alternatives prior to use. For the contaminant of a standard oil, waters, hydrocarbon and halogen parts which are the comercially available and promising alternatives were experimented at the same condition of Trichloroethane & Trichlorotrifluoroethane to check the cleaning performance. Overally, the removal efficiency of halogen solvent parts was better than that of hydrocarbon or waters parts for removing the standard oil used in this experiment.
