The national "973" project subject "Basic Research on Key Technologies for Corrosion and Protection of Marine Engineering Equipment Materials" was held a few days ago at the Ningbo Institute of Technology and Engineering, Chinese Academy of Sciences.
With the support of this subject, the State Grid Ningbo Power Supply Company and Ningbo The new graphene modified heavy-duty anti-corrosion coating jointly developed by the Institute of Materials and Materials passed the acceptance.
More than a dozen experts, including Academician Xue Qunji of Ningbo Institute of Materials, Chinese Academy of Sciences, Academician Ding Wenjiang of Shanghai Jiaotong University, and Academician Jian Xigao of Dalian University of Technology, attended the scene and went to the Zhoushan base to observe the project application pilot-the 380-meter-highest transmission tower anticorrosion project in the world.
According to reports, under the promotion of the national project, the team of Academician Xue Qunji and Researcher Wang Liping of the Ningbo Institute of Materials of the Chinese Academy of Sciences successfully developed graphene modified heavy-duty anti-corrosion coatings.
The world's highest transmission tower anti-corrosion project in Zhoushan is an important application achievement of this coating.

Through the improvement of the coating, the scientific research personnel put on the "anti-corrosion coat" for the steel in the coastal working environment, which increased the service life by 6 years, and solved the "old difficulty" of the corrosion resistance of offshore equipment.
According to scientific researchers, the introduction of graphene in the tropical marine atmosphere can significantly improve the anti-permeability of the service coating to corrosive media such as water and chloride ions.
It can greatly reduce the thickness of the coating while increasing the anti-corrosion life.
Graphene modified heavy-duty anti-corrosion coatings have previously passed the identification of achievements organized by the Chinese Society for Corrosion and Protection.
The key technical indicators have a salt spray resistance life of more than 9,000 hours, which greatly exceeds the technical level of 2000 hours of salt spray resistance of traditional heavy anti-corrosion coatings.
Up to now, the coating has been piloted in many areas such as Cixi 220kV Chongshou Substation, Beilun 220kV Kunting Substation, Yongtaiwen and Wenshan 220kV and 500kV iron towers in Ningbo area.
"The new coating not only slows down the corrosion of power facilities, but also ensures that the internal structure of power equipment is not damaged and extends the life of the transmission tower.
" said Zhou Kaihe, director of the Ningbo Power Supply Company's Double Innovation Center.
Ningbo is located in the coastal area, and there are a large number of chemical plants near transmission lines, high sulfur-containing waste gas content in the air, and the impact of humid sea breeze.
This causes the corrosion rate of coastal transmission towers to be 3 to 5 times faster than inland areas, which greatly increases maintenance costs.
It also leads to unnecessary grid operation risks, and the new graphene modified heavy-duty anti-corrosion coating fills the technical gap of domestic grid anti-corrosion coatings.At present, the technological achievements have been industrialized.
In addition to power transmission towers, they have also achieved large-scale applications in fields such as oil storage tanks, power distribution network facilities, bridge engineering, ships, and South China Sea marine facilities.
At the same time, this is the world's first time to complete the entire engineering chain of graphene modified heavy-duty anti-corrosion coatings, including material development, natural environment assessment, engineering demonstrations, and even large-scale production and application.
