Abstract
The invention relates to an all-chemical anticorrosive treatment method for a high-tension transmission line iron tower. The method comprises the following steps: (1) removing metal surface oil stains by using a surfactant; (2) removing rust from the lower part of the high-tension transmission line iron tower by using chlorohydric acid pickling solution; (3) removing rust from the upper part of the high-tension transmission line iron tower by using pickling passivation paste; (4) brushing the iron and steel surface with alkaline oxidation liquid, and performing chemical conversion treatment on the iron and steel surface; (5) brushing the iron and steel surface subjected to chemical conversion treatment with epoxy zinc rich primer; (6) brushing the iron and steel surface brushed with the epoxy zinc rich primer by using epoxy mica iron intermediate coat; and (7) brushing the iron and steel surface brushed with the epoxy mica iron intermediate coat by using epoxy resin finish. According to the method disclosed by the invention, each formula ingredient is reasonable, the process operation is applicable, the working efficiency is improved, and the effect is good.
