Niaj hnub no, galvanized steel kav muaj kev lag luam loj muag txhua xyoo hauv kev lag luam steel. Nyob rau hauv kev pom ntawm kev tsim technology, galvanized yeeb nkab tau muab faib ua ob hom: electro galvanized yeeb nkab thiab kub dip galvanized yeeb nkab. Nyob rau hauv lub neej, tib neeg feem ntau yog siv los hu rau kub dipped galvanized yeeb nkab li galvanized yeeb nkab. Hais lus ntxhib, kub dip galvanized yeeb nkab muaj kev ua tau zoo dua li cov yeeb nkab electro galvanized. Tsis tas li ntawd, vim cov nqi ua haujlwm ntau dua, cov yeeb nkab steel nqi yog me ntsis kim dua li cov yeeb nkab electro galvanized. Raws li txoj cai, thaum piv nrog kub dipped galvanized steel yeeb nkab, cov yeeb nkab steel yeeb nkab tsis muaj cov cuab yeej zoo rau tag nrho, tshwj xeeb yog cov cuab yeej ntawm corrosion kuj. Nyob rau hauv xyoo tas los no, vim hais tias ntawm lub teb chaws txoj cai, electro galvanized yeeb nkab tau raug tshem tawm los ntawm cov hlau ua lag luam.
Thaum nws los txog rau galvanized yeeb nkab, peb yuav tsum paub txog lo lus "galvanization". Kub dipped galvanized steel yeeb nkab yuav ua tiav qhov uas yuav tsim ib txheej ntawm alloy nyob ib ncig ntawm cov kav dej vim lub cev cov tshuaj tiv thaiv ntawm molten zinc thiab hlau. Yog li ntawd, hom yeeb nkab no muaj zog tiv thaiv corrosion dua li lwm hom. Tsis tas li ntawd, cov yeeb nkab steel muaj cov txheej txheej zoo heev nrog cov khoom muaj zog adhesion ntawm zinc txheej thiaj li ua tau zoo heev rau kev pab cuam lub neej ntawm cov kav dej. Tsis tas li ntawd, piv nrog lwm cov kav dej tsis tu ncua, cov kav dej kub dipped galvanized steel yeeb nkab muaj ntau qhov pom tseeb zoo hauv ntau lub hom phiaj hauv lub neej.
Kev hais lus, galvanization muaj feem xyuam rau kev siv cov zinc txheej tiv thaiv rau cov hlau lossis hlau yeeb nkab lub cev, txhawm rau tiv thaiv xeb. Kub-dipped galvanizing yog feem ntau txoj kev ntawm galvanization, nyob rau hauv uas cov yeeb nkab lub cev yog submerged nyob rau hauv ib da dej ntawm molten zinc. Feem ntau, raws li cov khoom siv raw ntawm cov kav dej, cov yeeb nkab galvanized muaj ob pawg: pre galvanized yeeb nkab thiab kub dipped galvanized steel yeeb nkab. Cov yeeb nkab ua ntej galvanized yog hais txog cov yeeb nkab welded uas tau dhau los ua degreasing, xeb tshem tawm, phosphorization, thiab ziab txheej txheem ua ntej galvanization. Cov kev kho mob ua ntej galvanization tso cai rau cov khoom kom yooj yim plated nrog zinc txheej, thiab tseem ua kom cov txheej txheej tuab, muaj zog txheej adhesion, thiab txhim kho corrosion kuj. Cov kav dej ua ntej galvanized yog siv dav hauv cov cua sov, dej thiab cov roj hluav taws xob, kev ua liaj ua teb tsev cog khoom, steel qauv siv teb nrog rau cov kav dej qis thiab nruab nrab.
