FIELD: metallurgy.SUBSTANCE: for enlargement of a usable temperature range, carbon tetrachloride is additionally added to it at the following component ratio (wt %): perchloroethylene - 33.00?45.00, carbon tetrachloride - 55.00?67.00. The proposed composition has considerable advantages in comparison to known ones - fusion temperature has been decreased by 38.0?41.1°C.EFFECT: possible use of a solvent under conditions of extremely lower temperatures.1 cl, 3 ex, 1 dwg |
