Description

KI. 12 a, 7 Wynalazek dotyczy cieczy chlodniczej, posiada¬ jacej wlasciwosci przeciwdzialania korozji metali.Dotychczas znane ciecze chlodnicze stanowia badz roztwory soli takich, jak NaCl, CaCU, MgCU, które powoduja znaczna korozje, badz tez zwiazki organiczne o niskiej temperaturze zamarzania, jak np. etanol, metanol, gliceryna, glikol, roztwór glu¬ kozy lub mieszanki elektrolitów ze zwiazkami organicznymi.W celu ograniczenia korozji znane jest równiez stosowanie dodatków do cieczy chlodniczych, np weglanu sodu lub potasu, wodorotlenku sodowego, soli barowych, fosforanów, soli chromowych szkla wodnego, fluorków metali alkalicznych itd.Obecnie stwierdzono, ze ciecz chlodnicza o wy¬ bitnych wlasciwosciach antykorozyjnych stanowia wodne roztwory acetonu, tlenku etylenu, butylo- aminy, /z-propyloaminy chinoliny, piperydyny lub pirydyny, przy czym zwiazki te stosuje sic od¬ dzielnie lub w mieszaninie.Do cieczy chlodniczej mozna w mysl wynalaz¬ ku dodac równiez chlorku wapniowego lub magne¬ zowego lub mieszaniny tych soli. Ponadto stwier¬ dzono, ze doskonale wyniki uzyskuje sie stosujac do powyzszych roztworów chlodniczych niewielkie domieszki alkoholów lub polialkoholów. PLKI. 12 a, 7 The invention relates to a cooling liquid having the property of preventing corrosion of metals. Until now known cooling liquids are either salt solutions such as NaCl, CaCU, MgCU, which cause significant corrosion, or organic compounds with low freezing point, e.g. . ethanol, methanol, glycerin, glycol, glucose solution or a mixture of electrolytes with organic compounds. In order to reduce corrosion it is also known to use additives to coolants, e.g. sodium or potassium carbonate, sodium hydroxide, barium salts, phosphates, chromium salts of glass water, alkali metal fluorides, etc. It has now been found that the coolant with outstanding anticorrosive properties consists of aqueous solutions of acetone, ethylene oxide, butylamine, quinoline-z-propylamine, piperidine or pyridine, and these compounds are used separately or in a mixture. Calcium chloride or magnesium may also be added to the coolant according to the invention. or mixtures of these salts. Moreover, it has been found that excellent results are obtained by applying slight admixtures of alcohols or polyalcohols to the above refrigeration solutions. PL
