Problems solved by technology

However, due to the poor penetration resistance and light aging ability of the existing coatings or coatings in the marine atmospheric environment, it is necessary to regularly carry out anti-corrosion maintenance on the steel structure of the platform in use. The maintenance period is about 2 years, and the maintenance will affect normal oil and gas production, but there are safety hazards

Description

technical field [0001] The invention relates to a long-acting anti-corrosion paint and a manufacturing method for the steel structure atmospheric area of ​​an ocean platform, which is used for anti-corrosion of the outer wall of the steel structure atmospheric area in the marine environment. Background technique [0002] The atmospheric area of ​​the steel structure of the existing offshore platform is also protected against corrosion by applying anti-corrosion coatings. However, due to the poor penetration resistance and light aging ability of the existing coatings or coatings in the marine atmospheric environment, it is necessary to regularly carry out anti-corrosion maintenance on the steel structure of the platform in use. The maintenance period is about 2 years, and the maintenance will affect normal oil and gas production, but there are also potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a long-term an...
