NEW FRIENDLY ENVIRONMENT INHIBITORS FOR ANTICORROSIVE PROTECTION OF COOLING WATER SYSTEMS

摘要

Using the microwaves energy, new polymers were synthesized by radicalic polymerization for anticorrosive and antiscaling protection of industrial cooling water systems. Electrochemical polarization techniques and metallurgical research microscopy technique have been carried out using different concentrations and combinations of organic compounds. Various corrosion parameters such as open circuit potential (OCP), current density, Tafel slopes, polarization resistance (Rp), and corrosion rate, etc.were recorded from electrochemical experiments for different metallic materials in cooling water systems. The obtained experimental results pointed out that, these new polymers are corrosion and antiscaling inhibitors and also, the environment friendly compounds. The inhibition activity of these new polymers is due to adsorption (chemisorption-specially) on the metallic surface, which leads to formation of a thin adsorption film, and this film inhibits the corrosion of the metallic material by a protective mechanism, forming insoluble complexes and repairing the porous oxide layers.
