Repair layer structure of anticorrosive coating of bridge steel structure

The repairing layer structure of the anticorrosive coating of the bridge steel structure can effectively solve the prominent problems that the period is too long, the manpower loss is large, the treatment effect is poor and the like in the repairing and recoating construction process of the anticorrosive coating of the bridge steel structure. Wherein the rust conversion layer can effectively replace polishing and rust removal treatment on the surface of the bridge steel structure, the surface treatment of the bridge steel structure can reach sa2.5 level, a large amount of labor is saved, and the construction period is shortened; and the zinc-rich layer is used for repairing coating construction defects caused by the fact that the surface of the base material is not treated in place, so that the tolerance degree of the repairing layer structure to the surface of the bridge steel structure can be improved. In conclusion, the repairing layer structure of the anti-corrosion coating of the bridge steel structure c
