Zinc plated and hot dipped galvanized bridge bridge differences
1, the main production process is different, hot-dip galvanizing is the zinc pot solution through, electro-galvanized through the electrode reaction.
2, the application in electroplated zinc steel anti-rust effect is not very good, mainly galvanized capacity of less than and galvanized uneven, generally two or three years there is rust, poor-quality rust more than 10 days exposed to wet conditions.
3, cold galvanizing process: steel surface after chemical cleaning in the electroplating, plating solution containing zinc oxide. DC pole steel pole placed in the plating of Zinc plate. Power zinc-steel surface by molecular replacement. If brightener passivation, you embody the cloud-like bright coating.
4, hot-dip galvanizing process: steel castings or immersed in a molten zinc bath surface formation of Zn-Fe alloy or zinc and zinc-iron alloy coating processes and methods.
