Leakage testing liquid preventing low-temperature icing and preparation method
ActiveCN101230246BProduce corrosionNo icingDetection of fluid at leakage pointProductsAlcoholFoaming agent
The invention provides a low-temperature icing preventing leakage detecting solution and the preparing method. The invention aims at solving the problem that leakage detecting solution ices. The invention is prepared by the matters of the following weight units: anhydrous calcium chloride 4-7, vesicant 5-7, distilled water 50-60. The vesicant is one or multifold combination which are selected fromcoconut oleic acid diethyl alcohol amide, cherry bay radical acylamide propyl lycine, coconut oleic radical acylamide propyl lycine, dodecyl dimethyl betaine and dodecyl dimethyl amine oxide. The invention does not ice within 3 hours at 18 DEG C below zero, has fine foaming effect, can meet the requirements on the leakage detecting solution in field task or in the condition of 18 DEG C below zero.
