Lub sijhawm tiv thaiv ntawm galvanized txheej ntawm cov yob lojgalvanized hlauyog ze ze rau lub thickness ntawm txheej.Feem ntau hais lus, hauv cov roj tseem ceeb qhuav thiab siv sab hauv tsev, thiab nyob rau hauv ib puag ncig hnyav, lub thickness ntawm galvanized txheej yuav tsum siab heev.Yog li ntawd, kev cuam tshuam ib puag ncig yuav tsum tau txiav txim siab thaum xaiv lub thickness ntawm galvanized txheej.Tom qab passivation kev kho mob ntawm galvanized txheej, ib txheej ntawm ci qub thiab zoo nkauj xim passivation zaj duab xis tuaj yeem tsim, uas tuaj yeem txhim kho nws txoj kev tiv thaiv zoo.
Muaj ntau ntau hom tshuaj galvanized, uas tuaj yeem muab faib ua cyanide plating tov thiab cyanide plating tov.Cyanide galvanizing tov muaj zoo dispersion thiab npog muaj peev xwm, txheej crystallization yog du thiab zoo, kev ua haujlwm yooj yim, ntau daim ntawv thov, tau siv rau hauv ntau lawm ntev.Txawm li cas los xij, vim hais tias cov txheej txheem plating muaj cov tshuaj lom cyanide, cov pa roj tawm hauv cov txheej txheem plating yog qhov tsis zoo rau cov neeg ua haujlwm noj qab haus huv, thiab cov dej khib nyiab yuav tsum tau kho nruj me ntsis ua ntej tso tawm.
Zinc yog cov hlau dawb-dawb, nkig ntawm chav tsev kub, soluble hauv acid thiab alkali, hu ua amphoteric hlau.Cov zinc ntshiab yog ruaj khov dua hauv huab cua qhuav, thiab me me hauv huab cua ntub lossis dej uas muaj carbon dioxide thiab oxygen.Ib txheej txheej nyias ntawm zinc carbonate yuav raug tsim rau ntawm qhov chaw, uas tuaj yeem ncua qhov corrosion ntawm zinc txheej.Lub corrosion kuj ntawm galvanized txheej nyob rau hauv aqueous tov ntawm acid, alkali thiab sodium chloride kuj muaj zog.Nws kuj tsis tiv taus corrosion nyob rau hauv cov huab cua uas muaj carbon dioxide thiab hydrogen sulfide thiab nyob rau hauv Marine atmospheres;Nyob rau hauv qhov kub thiab txias huab cua thiab muaj cov organic acid cua me me, galvanized txheej kuj yooj yim rau corroded.
