1. the heat-transfer fluid corroding for the inhibition of heat-transfer system, it comprisesCorrosion inhibitor, this corrosion inhibitor comprisesAzole compounds, andAt least one in tensio-active agent, colloidal silica or its mixture based on siloxanes,The specific conductivity of the heat-transfer fluid of this inhibition corrosion is not more than 200 μ

  • S/cm or equals 200 μ

    S/cm, and described tensio-active agent based on siloxanes is general formula R 3-Si-[O-Si (R) 2] x-OSiR 3polysiloxane, wherein R is alkyl or the polyalkylene oxide multipolymer with 1-200 carbon, x is 0-100, and described polysiloxane has at least one R group, the polyalkylene oxide multipolymer that wherein this R group is one or more oxyalkylenes with 2-6 carbon.
