| Abstract: | Here were introduced the currently situation of long-term anti-corrosion technologies in China and abroad:one was a relatively mature composite coating system with sprayed metal coating as a primer, and the other was a heavy-duty anti-corrosion coating system with zinc-rich primer as a supporting system. The differences of anti-corrosion performances of 3 typical anticorrosion coatings in atmospheric area of bridge steel structure were listed. According to the environmental characteristics of Xiamen Second East Passage, and combined with anti-corrosion technologies of domestic and foreign bridge steel structures, feasible anti-corrosion coating of epoxy zinc-rich primer-epoxy intermediate paint-fluorocarbon top coat was proposed for the outer surface of steel box girder. |
