Description
Technical Field
The invention belongs to the technical field of offshore wind power electric erosion protection, and particularly relates to a wind power tower finish paint containing indium chloride coated carbon nanofibers, and a preparation method and a use method thereof.
Background
Sea wind has the advantages of abundance, stability, high power generation efficiency and the like, but because the salt content of the sea atmosphere is high and the humidity is high, the sea wind power generation system has high requirements on the erosion resistance of the sea wind power generation set. The service environments of the offshore wind turbine generator are mainly divided into five types: atmospheric zone, splash zone, tidal range zone, full immersion zone, sea mud zone. The splash zone is generally an area 0-2 meters above sea level, which is an area where sea waves can splash and are not submerged by sea water when the sea water rises. The splash zone is affected by the corrosive environment of the ocean atmospheric region, and is also affected by wetting and impact of splash sea waves, and dry and wet are frequently alternated, so that the area which is most easily subjected to coating stripping failure due to erosion is formed.
At present, the offshore wind turbine generator mainly depends on high polymer coatings such as resin and the like, and anti-erosion protection is realized in a mode of partially assisting in sacrificing an anode, so that the purpose of prolonging the service life of the offshore wind turbine generator is achieved. Although the traditional resin-based polymer coating has good flexibility and corrosion resistance, the erosion resistance of the traditional resin-based polymer coating is low due to the characteristics of the traditional resin-based polymer coating. Particularly, the polymer coating mainly made of resin is easy to crack and peel under the influence of severe environments such as sea wave impact in a splashing area and the like, so that the protection effect and service life of the coating are greatly reduced, and the anti-erosion protection cost of the wind turbine generator is increased.
