Thermal sprayed zinc - aluminum anti - corrosion coating Typical applications(一)
The steel structure, steel box girder bridge, TV tower, building antenna, send substation, steel light pole and other outdoor steel structure, these steel components due to long-term exposure to the atmosphere, by climate change and sun and rain Leaching, the surface of rapid oxidation, the formation of a layer of ferric oxide, a serious impact on the strength of steel structure and service life. In order to prevent the oxidation of steel surface, in the past generally used to protect the paint, the corrosion life is generally 3-5 years, so the need for regular maintenance, maintenance, the common method is to copy the paint, cost a lot of manpower and resources. Is the use of steel surface spray zinc, spray aluminum technology to protect the anti-corrosion life of up to 30 years without maintenance.Such as zinc and aluminum coating in addition to paint closed, the longer the longer corrosion.
The surface of the structure only spray zinc, spray aluminum, can really play the role of anode protection, so as to achieve the purpose of long-term anti-corrosion steel structure. So many of the country's major projects and municipal projects are designated to adopt the process. Such as: the Yangtze River Three Gorges permanent gate, Shanghai Oriental Pearl TV Tower, Yangpu Bridge main guardrail, Guangzhou City, elevated steel girders, Shanghai Securities Building, steel structure antenna, Pudong Airport Road, common ditch gas pipeline, Shanghai Nanqiao 500,000 kilowatts substation Etc., to ensure that the major works of the century plan.
