Qhov sib txawv ntawm cov ntawv galvanized thiab cov ntawv galvalume yog nyob rau hauv txheej. Ib txheej ntawm cov khoom siv zinc yog sib npaug ntawm qhov chaw ntawm daim ntawv galvanized los muab kev tiv thaiv anode rau lub hauv paus hlau. Hauv lwm lo lus, qhov hloov pauv ntawm cov khoom siv zinc tiv thaiv lub hauv paus hlau. Tsuas yog thaum zinc corrodes tag nrho cov khoom siv hauv paus puas.
Lub nto txheej ntawmaluminium-zinc phajyog tsim los ntawm 55% txhuas, 43.5% zinc thiab lwm yam khoom me me. Microscopically, qhov saum npoo ntawm aluminium-zinc txheej muaj cov qauv honeycomb, thiab "honeycomb" muaj li ntawm txhuas muaj zinc. Nyob rau hauv cov ntaub ntawv no, lub aluminium-zinc txheej kuj plays lub luag hauj lwm ntawm anode tiv thaiv, tab sis nyob rau hauv ib tes, vim hais tias ntawm ib tug txo nyob rau hauv zinc cov ntsiab lus, thiab ntawm qhov tod tes, vim hais tias cov zinc cov ntaub ntawv yog qhwv nyob rau hauv aluminium thiab tsis yooj yim rau electrolyze, Lub luag haujlwm ntawm kev tiv thaiv anode txo qis heev. Yog li ntawd, ib zaug aluminium-zinc phaj raug txiav, nws yuav xeb sai sai thaum lub txiav ntug yog qhov pib ploj. Yog li ntawd, aluminium-zinc phaj yuav tsum tau txiav kom tsawg li sai tau. Tsuas yog tom qab cov npoo txiav raug tiv thaiv nrog cov xim pleev xim los yog zinc-nplua nuj xim tuaj yeem ua rau lub neej ntawm cov phaj txuas ntxiv.
Qhov saum npoo ntawm cov ntawv galvanized yog zoo nkauj dua li cov ntawv galvanized. Nyob rau tib lub sijhawm, tus nqi ntawm cov nplooj ntawv galvanized yog kim dua li cov nplooj ntawv galvanized, thiab tus nqi ntawm cov paj me me zinc yog kim dua li cov paj zinc loj.
