Login. Furthermore, researchers should pay more attention to the development of multifunctional corrosion inhibitors used in different working conditions. A list of important international events / trade fairs / conferences / webinars and courses with additional information. They react with the metal to form a protective layer on the metal surface thereby preventing interaction between the corrosive chemical and the metal. Also, in the present specification, the term "target calcium hardness" means any calcium hardness set by the user when she intends to change the constant raw water from corrosive to corrosive. All Rights Reserved. If you use in excess of the stoichiometric quantity, then theoretically you do not have any residual O2 left in the water. The step (c) is characterized by calculating the target alkalinity by the set target hydrogen ion concentration and the target calcium hardness of the constant source, and calculating the injection amount of the corrosion inhibitor at the calculated target alkalinity. endstream endobj 452 0 obj <>/Size 434/Type/XRef>>stream Steve JonesMaterials & Corrosion Engineerhttp://www.linkedin.com/pub/8/83b/b04. The nitrogen atoms in the corrosion inhibitor become cations after quaternization and are easily adsorbed by the negatively charged metal surface to form a monomolecular protective film.
