The use of nanotechnology in preventing corrosion of metal pipe and equipment of Shahid Abbaspour Dam ‎

In this work, a research carried out on a project by Shahid Abbaspour dam in Khuzestan province, was used to improve the epoxy paint used in staining the dam. Nanoparticles of titanium oxide contaminated with tin and then polymerized with polypyrrole were added to the paint used in the dam with various weight percentages of 0.1 to 1% by weight, and it was observed that if 0.5% of nanoparticles in paint is used, the epoxy fastness to corrosion increases significantly. In this field research, all materials used in the dam, including pipe, paint, and water from pipes and intrusive walls were used. An electrochemical method was used to conduct a corrosion test, one of the electrodes of which were pieces of tubes used in the dam, painted with normal epoxy and enhanced epoxy with nanoparticles. Meanwhile, for electrolyte used in tubes, various water samples taken from different points of the dam were used.
