采用磷化技术处理锈蚀输电铁塔,并在此基础上设计出与磷化液配套的防腐蚀涂装体系。试验结果表明,使用磷化技术处理锈蚀铁塔时,磷化液在锈蚀金属表面形成致密磷酸盐膜,清洗、锈层转化、锌层磷化以及表面调整可以一步完成;配制的涂装体系中,以有机涂料为底漆的涂装体系与磷化液配套使用机械性能与耐蚀性能良好。
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.
