Abstract

The invention discloses a new anti-corrosion process for an offshore wind power tower. The new anti-corrosion process for the offshore wind power tower comprises the following steps: defect treatmentfor the surface of a barrel body, grinding treatment for a steel structure, cleaning treatment for the steel structure, protection treatment for threads, sand blasting treatment, zinc spraying treatment, paint pre-coating treatment and paint treatment. The new anti-corrosion process for the offshore wind power tower has the following advantages: a method of combining emulsion cleaning with high-pressure water gun cleaning is adopted, and the cleanliness of the surface of a workpiece can be improved well; a method of shielding through equal-diameter bolts or packaging paper is adopted, and allthread holes are protected before sand blasting, so that the working efficiency is effectively increased; and a strict temperature control method is adopted, the optimal states of the environment requirements (temperature and humidity) of the sand blasting are ensured, and a coating time is strictly controller, so that the first-pass yield of coating is ensured.

Description

technical field [0001] The invention relates to the field of anti-corrosion technology, in particular to a new anti-corrosion process for offshore wind power towers. Background technique [0002] With the continuous improvement of basic wind power technology, offshore large-megawatt series towers have emerged as the times require, and have been continuously applied in practice. For example, Jiusi Jiangjiasha Yuanjing 4.2MW, Huaneng Dafeng Haizhuang 5MW, Three Gorges Dafeng Goldwind 6.45MW have achieved good practical results. Compared with ordinary towers, offshore large-megawatt series wind power foundations are in a harsher environment, and the corrosion of equipment is very serious, so the corresponding anti-corrosion level requirements are higher. Due to its unique surrounding environment and corresponding technical specification requirements, the maintenance cost of offshore wind turbines is relatively high. And the execution and supervision of the painting work must ...
