Galvanized kaujhais txog cov hlau kauj nrog ib txheej zinc ntawm qhov chaw. Galvanizing yog ib qho kev siv nyiaj ntau ntawm kev tiv thaiv xeb, thiab li ntawm ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau hauv cov txheej txheem no.
1. Mechanical Performance indicators, As
Thawj yog cov khoom siv ntawm cov khoom kub-dip galvanized. Cov khoom siv tshuab tuaj yeem txhais tau tias yog cov khoom lag luam uas tuaj yeem lees paub los ntawm kev ntsuas tensile, xws li lub zog tawm los, lub zog tensile, elongation, n tus nqi, r tus nqi, thiab lwm yam.
2. Txheej ntsuas kev ua tau zoo
Qhov tseem ceeb tshaj plaws ntawm cov khoom kub-dip galvanized yog cov txheej txheem kev ua tau zoo, uas feem ntau yog hais txog kev tiv thaiv corrosion ntawm txheej thiab adhesion kev ua tau zoo ntawm txheej. Corrosion kuj muaj xws li tsis kam mus rau ntsev tsuag thiab ya raws, thiab txheej adhesion yog hais txog cov khoom tsis kam mus tawg, tev, thiab hmoov txheej thaum ua.
3. Lwm qhov ntsuas kev ua tau zoo
Tsis muaj kev sim ze ze rau kev siv tiag tiag. Lwm yam khoom tseem ceeb suav nrog qhov zoo ntawm qhov chaw, xws li qhov zoo ntawm lub tsheb sab nrauv panels thiab cov khoom siv hauv tsev sab nrauv. Rau kev lag luam automotive, nto roughness tswj ntawm steel daim hlau kuj tseem ceeb heev. Hais txog lub ntsiab lus ntawm qhov zoo, ob peb kab lus tsis tuaj yeem piav qhia tag nrho. Qhov zoo tshaj plaws yog tsis siv nws ncaj qha rau hauv cov txheej txheem siv sib txawv, tab sis txhawm rau txheeb xyuas nws ua ntej. Kuj tseem muaj qee cov lus qhia. Piv txwv li, rau cov khoom siv alloyed lossis cov khoom kub-dip galvanized zoo tib yam, muaj cov npoo ntawm cov npoo thiab cov npoo tsis sib haum. Cov npoo ntawm untrimmed strip steel tau tso cai kom muaj cov kab nrib pleb me me hauv cov zinc txheej thiab cov npoo dawb.
