Kub dipped galvanized steel pipeis hauv kev tsim cov txheej txheem sivsteel kav dej tshem tawm rustdippedinto zinc kua ntawm 500 ℃ kub, thiab makingsteelsurface txuas zinc txheej thiaj li ua tiav lub hom phiaj los tiv thaiv xeb.
Galvanized steel yeeb nkab yog cov pa roj carbon steel yeeb nkab uas tau coated nrog tiv thaiv txheej ntawm zinc. Cov zinc txheej tau txais kev pab ua cov txheej txheem pov tseg, nws yuav xeb ua ntej cov pa roj carbon hlau nyob hauv qab nws. Galvanized steel yeeb nkab muaj ob hom: kub dipped galvanized steel yeeb nkab thiab txias galvanized steel yeeb nkab. Galvanized txheej yuav ntxiv dag zog rau los tiv thaiv corrosion kev ua tiav ntawm cov yeeb nkab steel.
Vim li cas ho siv zinc? Vim tias cov zinc keeb kawm nquag dua cov hlau ua haujlwm. Ntawm ib sab tes, zinc oxide ntawm galvanized steel yeeb nkab nto yog qhov compact, nws tuaj yeem nres oxidation (xeb) .Ntawm ntawm qhov tod tes, thaum hluav taws xob-tshuaj xeb tau tshwm sim, thawj hom hlau tsis xeb yog zinc dua li cov hlau. Cov zinc txheej nyhuv yog nres qhov kev txhim kho corrosion, thiab rub lub neej ntev ntawm cov yeeb nkab steel.
Galvanized steel yeeb nkab tsuas yog siv hauv kev xa cov pa roj carbon monoxide, chav. Nws tau siv los ua cov yeeb nkab dej, tab sis tom qab ob peb xyoos dhau los, muaj ntau cov xeb hauv cov yeeb nkab, thiab dej tau txais xim daj rau nqa hlau oxide. Cov dej tsis tsuas yog cov pa paug los yog lwm yam khoom ntxuav tu, tab sis kuj nqa cov kab mob tsim nyob rau sab hauv uas tsis du. Raws li qhov kev xeb, cov dej muaj cov hlau hnyav lub cev ntau dhau thiab ua rau tib neeg muaj kev noj qab haus huv. Vim li no, tsim lub teb chaws majbanned nws siv raws li cov kav dej txij li xyoo 1960.
Kub dipped galvanized steel yeeb isin raug 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 txheej 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 los ntawm kev txhim kho ntawm cov khaub thuas dov txias, nws tau tsim kho ntau xyoo tsis ntev los no. Nrog lub high-voltage kis tau tus mob, kev thauj mus los, kev sib txuas lus, kev tiv thaiv cov khoom xav tau cov qauv siab dua, kub kub galvanizing kev xav tau tseem nce.
