| titleOfInvention | Corrosion prevention method |
| abstract | The invention relates to a method of preventing corrosion for bringing a film-forming amine and an alkalinity component M to coexist in a cooling water system, forming an anticorrosive coating on the surface of a metallic element. contact with the cooling water system, and remove corrosion. In the present invention, a neutral amine is used as the M alkalinity component, and the M alkalinity of the cooling water system at the time of the initial treatment is adjusted to 90 mg / l of CaCo 3 or more. Alternatively, an inorganic alkali is used as the M alkalinity component, and the M alkalinity of the cooling water system at the time of the initial treatment is adjusted to 120 mg / l of CaCo 3 or higher, and the pH is set to 9.5 or higher. |
