Problems solved by technology

[0004] At present, the service life of the tower tube needs to reach more than 10 years, and at present, the protective layer on the surface of many tower tubes begins to fall off and fail after 3 years of use. According to the research, the main reason for these phenomena is the problem of the surface treatment method, which leads to the The service life of the protective layer of the cylinder is not up to standard

Embodiment Construction

[0033] The method for surface treatment of a wind power tower includes the following steps: cleaning the surface of the tower; shot blasting the surface of the tower; spraying a primer on the tower; spraying an intermediate paint on the tower; and spraying a top coat on the tower.

[0034] Surface cleaning and shot blasting can avoid various surface defects in the later stage, and at the same time improve the adhesion of the primer. The primer provides the adhesion between the steel plate and the intermediate paint, and at the same time acts as a direct protective layer, shielding corrosion and electrochemical effects. The main function of the intermediate paint is to improve the overall performance of the coating system, increase the overall thickness of the paint film, enhance the shielding effect of the entire paint film system on external water and electrolytes, and solve the possible incompatibility between the top coat and the primer. The main function of the topcoat is ...

Abstract

The invention relates to a wind power surface treatment method, in particular to a wind power tower drum surface treatment method. The wind power tower drum surface treatment method comprises the following steps that the surface of a tower drum is cleaned; the surface of the tower drum is subjected to shot blasting; primer is sprayed to the tower drum; intermediate paint is sprayed to the tower drum; and finish paint is sprayed to the tower drum. The wind power tower drum surface treatment method can effectively ensure anti-corrosion performance, ultraviolet aging resistance and wind sand corrosion resistance, meets the long-term anti-corrosion requirement, improves the working efficiency by shortening the spraying time through drying, is high in air-free spraying effect, and is smooth insurface.

Description

technical field [0001] The invention relates to a wind power surface treatment method, in particular to a wind power tower surface treatment method. Background technique [0002] Wind power, as a new type of green and clean energy, is actively developing because of its abundant energy reserves and huge market prospects, which can effectively improve the shortage of energy supply. [0003] Since wind power generation is basically in the wild or at sea, the working environment is harsh, and the wind power tower needs to be able to withstand the erosion of wind, rain, frost, sand and dust, as well as the influence of sunlight and cold currents, so the surface treatment of the tower is particularly important , The surface treatment of the tower directly affects the service life of the tower. [0004] At present, the service life of the tower tube needs to reach more than 10 years, and at present, the protective layer on the surface of many tower tubes begins to fall off and fai...
