Embodiment 1
[0026] Use a soft brush to gently brush the surface of the rusty bronze, and then repeatedly blow the surface with dry nitrogen to remove dust, particles and harmful powdery rust on the bronze surface;
[0027] The pretreated bronze was hung in an atmosphere box, 10.0% benzotriazole, 5.0% 1-phenyl-5-mercaptotetrazolium, 3.0% 2-mercaptobenzoxazole, 2.0% 2-mercaptobenzimidazole, the balance is a solvent ethanol composite gas phase corrosion inhibitor solution placed at the bottom of the atmosphere box, nitrogen gas is passed through the microporous diffuser for 120 minutes to vaporize; pre-film at 20-30 ° C for 72 hours , followed by nitrogen gas for 60 minutes to blow off the corrosion inhibitor and ethanol molecules attached to the surface;
[0028] 5.0% of tridecafluorooctyltriethoxysilane, 5.0% of heptadecafluorodecyltriethoxysilane, 2.0% of 4-methyl-tridecafluorodecyltriethoxysilane, the balance The fluorosilane solution that is ethanol solvent is placed at the bottom of t...
