Qhov kub-dip galvanization yog dab tsi?

Kub-dip galvanization yog ib hom ntawv ntawm galvanization. Nws yog txheej txheem ntawm txheej txheej hlau thiab hlau nrog zinc, uas alloys nrog saum npoo ntawm lub hauv paus hlau thaum nqus cov hlau hauv da dej ntawm molten zinc ntawm qhov kub ntawm 840 ° F (449 ° C). Thaum kis rau cov huab cua, cov ntshiab zinc (Zn) reacts nrog oxygen (O2) los tsim zinc oxide (ZnO), uas txuas ntxiv nrog cov pa roj carbon dioxide (CO2) los tsim zinc carbonate (ZnCO3), feem ntau npub grey, ncaj ncees cov khoom siv uas tiv thaiv cov hlau hauv qab los ntawm kev xeb ntxiv nyob hauv ntau yam. Galvanized steel yog dav siv hauv cov ntawv thov qhov twg qhov kev txhim kho corrosion yog xav tau yam tsis muaj tus nqi ntawm cov hlau tsis xeb, thiab suav hais tias yog zoo dua li cov nqi thiab lub neej.
