Problems solved by technology

[0004] It can be seen that the blades of the wind turbine in the wind turbine have a direct relationship with the working life and efficiency of the wind turbine. Generally, the wind turbine is installed outdoors and will be eroded by multiple factors in the natural environment. Phenomenon, will directly lead to the decline of its mechanical properties, unable to maintain better work efficiency

Abstract

The invention discloses a wind turbine blade passivation treatment process, and relates to the technical field of metal surface treatment. The wind turbine blade passivation treatment process comprises the following steps that after wind turbine blades are cleaned, then the solid solution treatment is carried out, and the wind turbine blades subjected to solid solution treatment are obtained through the assivation treatment by using a polyether polyol-based passivation solution. According to the wind turbine blade passivation treatment process, the compactness of passivation films can be remarkably improved, meanwhile, by virtue of the synergistic effects of trichlorocyanamide and urea phosphate, the film forming property is greatly improved, and the infiltration of impurities such as water is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a passivation treatment process for wind power generator blades. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators (including devices), steering devices (tail fins), towers, speed-limiting safety mechanisms, and energy storage devices. The wind generator is mainly driven by the wind through the impeller to rotate and generate electricity. The wind wheel usually consists of 2 to 3 blades, which are the main equipment of the wind generator. [0003] The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of t...
