Galvanized steel yeeb nkabyog lub xeev ntawm molten hlau zinc thiab hlau substrate cov tshuaj tiv thaiv ntawm alloy txheej, yog li ntawd lub substrate thiab txheej ua ke ntawm ob qho tib si.Ntawm kev siv thev naus laus zis hauv galvanized, Kub dip galvanized ua ntej ua lub pickling, thiaj li yuav tshem tawm cov hlau nto ntawm hlau oxide, tom qab pickling, los ntawm ib tug aqueous tov ntawm ammonium chloride los yog zinc chloride los yog ammonium chloride thiab chlorinated zinc tov aqueous tov tank. rau tu, thiab ces mus rau hauv kub-dip plating da dej.Kub-dip galvanized nrog txheej txheej uniformity, muaj zog adhesion, lub neej ntev thiab lwm yam zoo.Yog li ntawd, cov tswv yim los ntawm kub dip galvanized steel substrate thiab molten da dej los ntawm complex lub cev, tshuaj cov tshuaj tiv thaiv, tsim ib tug corrosion-resistant zinc-alloy txheej ntawm compact qauv.Yog li ntawd, galvanized steel alloy txheej thiab txheej ntawm cov ntshiab zinc, steel puag sib xyaw ua rau muaj peev xwm corrosion.

Zinc tshuaj lom neeg kev sib deev yog siab dua hlau, thaum electrochemical corrosion tshwm sim, thawj corrosion yog zinc es tsis txhob hlau, zinc oxide thiab kuj compact, uas yuav tiv thaiv tau oxidation ntxiv.Feem ntau galvanized steel muaj qhov zoo corrosion tsis kam, corrosion ntawm faus hlau kav yog muab faib ua ob hom corrosion tsis zoo thiab localized corrosion, localized corrosion feem ntau dominated, qhov txaus ntshai yog qhov loj tshaj.Hlau corrosion nyob rau hauv av electrochemical dissolution txheej txheem yog tsuas yog vim yog tsim ntawm corrosion hlwb ua rau pipeline corrosion perforation.Nias lub xov tooj ntawm tes anode thiab cathode spacing loj, tab sis kuj zoo li cov hlau rau hauv micro-cell corrosion corrosion thiab macro cell corrosion ob pawg.Electrochemical corrosion rau faus pipeline txheej txheem, steel corrosion inhibition txoj kev los ntawm qhov pib txheej txheem.Yog tias cov yeeb nkab phab ntsa ntxiv rau cov txheej txheem tiv thaiv corrosion, lub voj tsis kam tuaj yeem nce ntxiv, txo qhov corrosion tam sim no;Sab nraud DC fais fab mov, kom cov av yeeb nkab ua rau tsis zoo, tsim cathodic tiv thaiv anode muaj peev xwm sib txawv tuaj yeem raug tshem tawm los ntawm cov hauv paus hniav kom nres cov txheej txheem ntawm anode thiab cathode mus.Tab sis ib zaug cov txheej txheem tiv thaiv corrosion puas lawm, cov khoom siv hlau raug yuav ua kom muaj zog hauv zos.Yog li ntawd, anti-corrosion txheej thiab cathodic tiv thaiv ua ke tshem tawm txoj kev no yog lub rooj, kev lag luam thiab siv tau zoo.
