Steel structure spray aluminum zinc anticorrosion technology advantage
Arc spraying and flame spraying, compared with the electricity instead of gas burning, greatly improving the work efficiency and work safety, especially the emergence of mechanization of arc spraying equipment, electric arc spraying technology has been completely can meet the needs of bridge construction time limit for a project, and the arc temperature is much higher than the flame, coating binding force are also far bigger than flame spraying, so the coating quality can also meet the needs of the long-term anticorrosion. The United States due to the high cost of artificial, using electric arc spraying anti-corrosion construction costs even lower than heavy anticorrosive paint. After decades of test proves that the coating technology is one of the best ways to long-term anti-corrosion steel structure, the conclusion has been the world the government department and the engineering recognition in many countries.
The application of spray aluminum zinc corrosion of steel structure
Successively in coal mine, railway, water conservancy, port terminals, metallurgy, machinery, radio and television, medical, power, fire and other fields is widely used, such as baoshan iron and steel group, horse trails mountain wharf steel pile, Shanghai maglev fast train tracks function, the Yangtze river three gorges water conservancy hub project, steel box girder of wuhan junshan changjiang river bridge and bridge deck national key construction projects and ChunAn thousand island lake huangbo Nanpu Bridge, the Yangtze river bridge, the prison creek bridge, overpass in guangzhou airport three yuan, if the canal xu lian highway bridge steel structure bridge adopts the electric arc spraying long-term anti-corrosion technology for corrosion protection, and achieved very good preservation effect. China is fully capable of using arc spraying long-term anticorrosion technology to solve the corrosion protection of the country's large steel bridge.
Heavy anticorrosive technology of bridge steel structure, gradually formed two big development trend, the one is developing rapidly with inorganic zinc-rich coating base system of heavy-duty, 2 it is relatively mature in metal spraying layer of the system as a basal, these two systems because it has excellent anti-corrosion performance and environmental adaptability under the attention of all kinds of bridge steel structure anticorrosion. Over the coming decades will be for the country save a lot of steel structure bridge anti-corrosion maintenance costs, reduce environmental pollution, prolong the service life of steel Bridges, produce a great economic and social benefits.
