Galvanizing, los yog galvanization, yog txheej txheem tsim khoom uas txheej txheej ntawm zinc yog siv rau hlau lossis hlau kom muaj kev tiv thaiv thiab tiv thaiv xeb. Muaj ntau cov txheej txheem galvanizing muaj, tab sis feem ntau muab thiab siv txoj kev hu ua kub-dip galvanizing.
Galvanized hlauyog ib qho ntawm cov hlau nrov tshaj plaws vim nws qhov ntev ntev, muaj lub zog thiab kev tsim ntawm cov hlau ntxiv rau kev tiv thaiv corrosion ntawm zinc-hlau txheej. Cov zinc tiv thaiv lub hauv paus hlau los ntawm kev ua raws li kev tiv thaiv corrosive cov ntsiab lus, thiab kev txi ntawm txheej txheej ua rau cov khoom siv hlau ntev ntev thiab zoo.
Qhov kev ua tau zoo no ua rau nws siv tau rau ntau yam haujlwm thiab kev lag luam, suav nrog kev ua liaj ua teb, hnub ci, tsheb, kev tsim kho, thiab lwm yam. Hauv qab no, peb lub hom phiaj los muab cov lus piav qhia txog yuav ua li cas galvanized steel ua tiav, cov txheej txheem sib txawv ntawm galvanization, nws cov txiaj ntsig, thiab nws siv li cas hauv ntau yam kev lag luam.
Cov kauj ruam hauv txheej txheem galvanizing yog raws li nram no:
Cov hlau yog ntxuav nyob rau hauv ib tug degreasing tov
Tom qab ntxuav, cov hlau yog pickled los ntawm kev txo qis rau hauv ib lub vat ntawm diluted kub sulfuric acid
Cov hlau yog ces fluxed nyob rau hauv ib tug aqueous tov (feem ntau zinc-ammonium chloride)
Tom qab lub flux, cov hlau yog galvanized los ntawm immersion nyob rau hauv ib lub vat ntawm molten zinc
Tom qab ntawd, cov hlau raug tshuaj xyuas kom sib xws thiab ua tiav txheej
