Embodiment Construction
[0017] figure 1 A preferred embodiment of the main cable protective coating structure of the suspension bridge of the present invention is schematically shown. Wherein the main cable 1 is composed of multiple strands of high-strength galvanized steel wires, through a plurality of clamps (not shown in the figure) fixed on the main cable to form a steel wire bundle with a generally circular cross-section. According to the method for protecting the main cable system of the present invention, the surface of the main cable 1 is routinely cleaned to remove rust and other dirt, and then a layer of phosphating primer 2 is firstly applied. The phosphating primer 2 can adopt the XF06-2 type phosphating primer developed by the applicant, which is composed of polyvinyl butyral resin, zinc chromate antirust pigment, solvent and phosphating solution. The phosphating primer has excellent antirust ability, has phosphating and repairing functions on the mechanical damage of the galvanized ste...
