Marine anti-corrosion technology seizes the spray "tiger"

Abstract: “The cross-sea bridge warms on both banks, Lianggang Bay, Ligang Bay.” Academician Hou said that to build the Shandong Peninsula Blue Economic Zone, marine corrosion research work is indispensable. After more than two years of practical application, the anti-corrosion material has good impact resistance and excellent protection effect, and the specific service life needs to be tested for a longer period of time.

“Cross-sea bridge warms on both banks, Lianggang Bay Libiwan. The tides rise and fall, the waves splash, the study found that the spray is a 'metal tiger'. The successful application of marine corrosion and anti-corrosion technology to protect the sea bridge and blue waves The long-term stability of Lianggang." On October 8, the 60th anniversary of the establishment of the Institute of Oceanography of the Chinese Academy of Sciences, the recognition of the top ten scientific and technological achievements of the 60th anniversary of the founding of the Institute, which is one of the results of the "marine environmental corrosion research and its control technology" Comment.

Leading the scientific and technological achievements is the academician of the Chinese Academy of Engineering and the researcher of the Institute of Oceanography of the Chinese Academy of Sciences Hou Baorong. He introduced that corrosion is closely related to the national economic construction. “Seawater is a very harsh corrosive material for various metal structural materials in marine engineering. The splashing waves are actually the natural enemies of these marine projects. In China, there are 1.5 tons of steel per second. Corroded." Hou Baorong told reporters that from the harm of marine corrosion, it can shorten the service life of various structural materials, such as steel piles, once corroded, it can only be used for 10 years, it can only be used for 5 years. If anti-corrosion is not good, life expectancy will be shortened, directly affecting the safety of marine engineering, causing waste of resources and energy, and hindering the development of new technologies.

Conquering the "natural enemies" into the national support plan

"In the face of marine corrosion, how to carry out the necessary protection and control measures, the Institute of Oceanography of the Chinese Academy of Sciences began research on anti-corrosion technology 50 years ago." Hou Baorong said, "The current team is expanding, the results are increasing, and the country is ten The five-support plan focuses on the study of corrosion protection of marine structures to solve the most serious problems in the splash zone."

Hou Baorong is the only academician in China's marine corrosion industry. He has been engaged in marine corrosion and protection research for more than 40 years and has achieved outstanding scientific achievements in the field of marine corrosion and protection. In 2007, as the chief scientist, he undertook the support project of the Ministry of Science and Technology of the “Oscillation and Control Technology for the Splash Zone of Marine Engineering Structures”. More than 20 universities, research institutes and enterprises in the United Nations jointly studied and solved the serious corrosion problems in the splash zone. And made a number of demonstration projects.

These results can be used not only for the corrosion protection of new steel facilities, but also for the protection of corrosion of existing steel facilities. It can also be applied to underground pipeline protection under various corrosive environments. It has wide applicability and economic benefits, making China a A country that has mastered this technology after the United States and Japan.

New opportunities in the industry

Haixiwan Shipbuilding Base, Jiaozhou Bay Cross-sea Bridge, Dongjiakou Port Area... Counting the major projects in Qingdao and abroad in recent years in Jiaozhou Bay, it is found that these major projects with a total investment of tens of billions of yuan are invariably deep. Rooted in the blue ocean around.

Academician Hou said that as a famous marine city in China, most of Qingdao's major industries are related to the ocean, but at the same time, the harshness of the marine environment often leads to several times the corrosion rate of various materials inland. According to projections, the annual loss caused by corrosion in Qingdao is about 5 billion yuan.
"If the anti-corrosion work is done well, 25% - 40% of the losses can be completely avoided, which will help promote the Qingdao economy to develop better and faster."

Academician Hou said that to build the blue economic zone of Shandong Peninsula, marine corrosion research work is indispensable. Marine corrosion research has brought new opportunities for the industry. “If our work is done well, it will reduce losses and save energy accordingly. We have done some anti-corrosion experiments in Qingdao Port Liquid Chemical Terminal, Shengli Oilfield Offshore Oil Platform and Rizhao Port Coal Terminal, and the effect is not bad.”

Academician Hou introduced that the new anti-corrosion technology can not only be used for corrosion protection of new steel facilities, but also has good protection effect on corrosion repair of existing steel facilities. It can also be applied to underground pipeline protection under various corrosive environments. Sexuality and long-term economics. After more than two years of practical application, the anti-corrosion material has good impact resistance and excellent protection effect, and the specific service life needs to be tested for a longer period of time.
