Anti-corrosion Painting of Corroded Transmission Towers

The performance of phosphating solution used as pretreatment agent of corroded transmission towers was studied and the matchable coating system was developed. The results of treatment of corroded transmission towers by phosphating solution showed that in forming the process of a dense protection film of phosphate on the surface of corroded steel, the phosphating liquid cleaning, rust conversion, zinc phosphating and surface conditioning were finished at the same time. The results also showed that using organic coatings as primer, the coating system had a good performance in mechanical properties and corrosion resistance with the matchable phosphating solution.
