Corrosion inhibitor for galvanic pair STEEL-COPPER FOR WATER COOLING SYSTEMs |
| 摘要 |
A corrosion inhibitor for low-alloyed steels for water systems contains phosphate anions, zinc cation and anion of oxidizing acid. Molybdate anions () are introduced as anion of oxidizing acid in the form of alkali metal salt with the concentration of 25 mg/dm. At that the ratio of concentrations phosphate-anion, zinc-cation and molybdate-anion is of 3.9:2.4:1. |
