Kub dipped galvanized steel yeeb nkab yog nyob rau hauv kev tsim cov txheej txheem siv cov kav hlau xeb tshem tawm xeb xaim rau hauv cov dej ua kua zinc ntawm 500 ℃ kub, thiab ua cov steel hlau txuas nrog zinc txheej thiaj li ua tiav lub hom phiaj los tiv thaiv xeb.
Kub galvanizing yog ib hom kev tiv thaiv kev tiv thaiv kev kho mob, siv hauv hom hlau cov khoom lag luam. Txij li thaum 1836 Fabkis siv kub kub galvanizing hauv kev lag luam thawj zaug, nws muaj ntau dua 180 xyoo. Txawm li cas los xij ua raws li kev txhim kho ntawm cov khaub thuas dov txias, nws tau zoo heev nyob rau xyoo tsis ntev los no. Nrog rau txoj kev xa hluav taws xob loj, kev thauj mus los, kev sib txuas lus, kev tiv thaiv cov khoom lag luam xav tau cov qauv siab dua, kub kub galvanizing xav tau kuj nce.
Kev ua ntawm kub kub galvanizing:
Tiav khaub noom pickling - ntxuav - plating - ziab - dai plating - txias - tshuaj - ntxuav - sib tsoo - kub galvanized tag.
Zinc tuab rau kub galvanized steel yeeb nkab
Kub galvanized steel yeeb nkab zinc txheej thickness yog 35μm, thiab tuab tshaj plaws yog nce 650μm. Hloov txias txias zinc txheej tuab tsuas yog 5-15μm. Zinc txheej muaj qhov cuam tshuam los ntawm kev tiv thaiv huab cua thiab hluav taws xob tiv thaiv.
Qhov kev tshawb xav ntawm kub galvanized steel yeeb nkab zinc txheej nyhuv ua rau tiv thaiv xeb
Kev coj ua ntawm kub kub kub, nws yuav tsim zaj duab xis ntawm zinc-steel alloy txheej ua ntej, saum toj no nws yog ntshiab zinc txheej. Thaum cov huab cua corroded zinc txheej, nws yuav tsim txheej txheej ntawm ZnO, Zn (OH) 2 thiab zaj duab xis zinc carbonate tiv thaiv zaj duab xis. Uas muaj cov nyhuv ntawm anti tiv thaiv huab cua. Thaum zaj duab xis no tau raug rhuav tshem, ib qho tshiab yuav tsim. Thaum cov zinc txheej pov tseg ntau heev, zinc pib siv hluav taws xob tiv thaiv kev lag luam. Zinc raws li thawj lub caij yaj. Nws pom tseeb tias kub galvanized steel muaj zoo dua tiv thaiv kev ua qog dua li txias galvanizing yeeb nkab.
Ntev npaum li cas kub kub galvanized steel yeeb nkab lub neej?
Galvanized steel yeeb nkab tau ntev lub neej. Tab sis nyob rau hauv txawv tej yam kev mob lub neej ntawm kev siv yog txawv. Feem ntau hais lus, 13 xyoos nyob rau hauv cheeb tsam kev lag luam hnyav, 50 xyoo rau dej hiav txwv ib puag ncig, 104 xyoo nyob hauv nroog, 30 xyoo hauv nroog. Qhov tseeb galvanizing tau ua si lub luag haujlwm ntawm kev tiv thaiv xeb, nws tsis tas yuav tsum tau kho lwm yam xeb.
Cov txheej txheem kub galvanizing tshwj xeeb haum rau cov muaj zog-acid, alkali sis thiab lwm yam muaj zog tiv thaiv kev mob. Qhov no yam fastener siv ntau nyob rau sab nraum ntawm steel ntauwd pab.
