For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of surface galvanizing technique of guide hook of fuse switch is provided, may further comprise the steps:
1) skimming treatment: guide hook is infiltrated in degreased cleaning agent, remove surface and oil contaminant, then running water wash;
2) cleanup acid treatment: with the etch in aqueous sulfuric acid of the guide hook after the skimming treatment, remove the oxide film on guide hook surface, then washing, drying;
3) soak and help the plating solvent: with the guide hook after the cleanup acid treatment 55-65 ℃ helped in the plating solvent dipping 3-8 minute;
4) drying and forewarm: guide hook is pulled out from help the plating solvent, then drying and forewarm under 120-180 ℃ of temperature;
5) pot galvanize: kept 0.5-1.5 minute in the galvanizing flux with 450-470 ℃ of the immersion of the guide hook behind the drying and forewarm;
6) arrangement cooling: water-cooled behind the remaining zinc in manual removal surface;
7) passivation: in chromatedsolution, keep 8-15 second, then cleaning, drying.
In a preferred embodiment of the present invention, contain the inhibiter of 0.1%-0.5% in the described aqueous sulfuric acid.
In a preferred embodiment of the present invention, described help the plating solvent be zinc ammonium chloride solution, pH value is 4.5-5.5, wherein contains the glycerol of 0.8%-2%.
In a preferred embodiment of the present invention, contain the metallic aluminium of 0.01%-0.02% in the described galvanizing flux.
