Galvanized ntawv yog hais txog txheej txheej zinc hlau rau ntawm qhov chaw ntawm cov pa roj carbon zoo tib yam steel los ua lub luag haujlwm ntawm kev tiv thaiv corrosion thiab kho kom zoo nkauj. Muaj ntau hom ntawv galvanized raws li qhov sib txawv thicknesses, siv thiab ntau lawm txheej txheem. Cov nram qab no yog ob peb hom galvanized ntawv qauv:
SGCC: Lub npe tag nrho yog zoo tib yam kub-dip galvanized ntawv. Hom ntawv galvanized no feem ntau siv rau hauv kev tsim kho, lub teeb muaj kev lag luam thiab lwm yam kev lag luam. Nws lub ntsiab nta yog corrosion kuj, siab zog thiab zoo formability.
DC51D + Z, DC52D + Z, DC53D + Z: Cov nplooj ntawv galvanized no yog cov ntawv uas muaj cov pa roj carbon txias uas muaj qhov zoo ntawm qhov chaw du thiab kev ua haujlwm zoo passivation. Lawv tsuas yog siv hauv tsheb, khoom siv hluav taws xob thiab lwm yam haujlwm.
DX51D+Z, DX52D + Z, DX53D + Z: Cov nplooj ntawv galvanized no yog cov ntawv uas tsis tshua muaj carbon kub dov nrog qhov zoo ntawm lub zog siab thiab zoo xim adhesion. Lawv tsuas yog siv rau hauv kev tsim cov khoom siv hauv tsev, cov vaj huam sib luag zoo nkauj thiab lwm yam.
SECC, SGCD1, SGCD2, SECE: Cov nplooj ntawv galvanized no yog cov nplooj ntawv electrolytic zinc steel nrog qhov zoo ntawm qhov ntev thiab ntau yam kev siv. Lawv tuaj yeem siv rau hauv cov khoom siv hluav taws xob, kev sib txuas lus thiab lwm yam lag luam.
Tsis tas li ntawd, qee cov tuam ntxhab tau tsim tshwj xeeb cov qauv thiab cov qauv ntawm cov ntawv galvanized raws li qhov xav tau ntawm cov neeg siv sib txawv. Yog li ntawd, muaj ntau ntau hom galvanized ntawv.
