Abstract

The invention relates to a paint spraying process for a tower drum of a wind-driven generator. The paint spraying process comprises the following steps that 1), cleaning is carried out on the surfaceof the tower drum; 2), sand blasting treatment is carried out on the surface of the tower drum to enable the surface roughness of the tower drum to reach 40-80 microns; 3), a primer is sprayed; the primer adopts an epoxy zinc-rich primer; 4), intermediate paint is sprayed; the intermediate paint adopts epoxy thick paste paint or epoxy micaceous iron paint; and 5), finish paint is sprayed. The performance of the tower drum of the wind-driven generator processed by adopting the paint spraying process in the aspects of water resistance, salt water resistance, temperature resistance, aging resistance, corrosion resistance life and the like is remarkably improved, the mechanical performance is excellent, and the problem that the corrosion resistance life of an existing tower drum of the wind-driven generator cannot meet the requirement of ISO 12 944-1 is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a painting process for a wind turbine tower. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Our country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kw, of which, the wind energy reserves on land are about 253 million kw (calculated from the height of 10m above the ground on land), and the wind energy reserves that can be developed and utilized at sea are about 750 million kw. [0003] Wind is one of the energy sources without pollution. And it is inexhaustible and inexhaustible. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation, the use of wind power generation according to local conditions is very s...
