THE COMPOSITION FOR PREVENTING CORROSION
A corrosion inhibitor is provided to inhibit the activation of a corrosion layer by forming a passivation layer by the chemical reaction with a metal surface corrosion layer. A corrosion inhibitor comprises 55-65 wt% of orthophosphoric acid (44% H3PO4); 5-7 wt% of zinc nitrate (Zn(NO3)2.H2O); 6-8 wt...

| description | A corrosion inhibitor is provided to inhibit the activation of a corrosion layer by forming a passivation layer by the chemical reaction with a metal surface corrosion layer. A corrosion inhibitor comprises 55-65 wt% of orthophosphoric acid (44% H3PO4); 5-7 wt% of zinc nitrate (Zn(NO3)2.H2O); 6-8 wt% of aluminum nitrate (Al(NO3)3.9H2O); 4-5 wt% of potassium ferrocyanide (K4Fe(CN)6.3H2); 0.03-0.05 wt% of a nonionic surfactant; and the balance of desalted water. Preferably the nonionic surfactant comprises 86 % of polymer fluorochemical active; 12 % of nonfluorochemical active; and 2 % of a co-solvent. |
