FREMGANGSMAATE FOR BEHANDLING AV VANDIGE FLUIDER |
摘要 |
<p>The invention relates to a process making it possible to reduce the corrosion of metals and alloys of heat exchanger circuits where aqueous heat transfer fluids are circulating and which may contain anti-freeze products. The process consists in mixing with these aqueous heat transfer fluids on the one hand from 0.05 to 5 percent by weight of one or more salts of alkali metals or of amines of dicarboxylic aliphatic acids of the formula (CH2)n(COOH)2 in which n is comprised between 2 and 10 and on the other hand from 0.05 to 2.5 percent by weight of one or more polyols comprising a number of carbon atoms between 5 and 12 and a number of alcohol functions between 5 and 12 and possessing no reducing power.</p> |
