1. Kev faib cov qauv raugalvanized steel ntawv
Galvanized steel phaj yog steel phaj uas yog coated nrog ib txheej ntawm zinc rau saum npoo ntawm cov hlau phaj. Nws muaj zoo corrosion kuj thiab zoo nkauj zog. Galvanized steel ntawv tuaj yeem muab faib ua ntau qib raws li cov txheej txheem zinc txheej tuab, qhov chaw nyob, thiab tshuaj lom neeg muaj pes tsawg leeg. Muaj ob
Cov txheej txheem kev faib qib sib faib rau cov ntawv galvanized steel:
1. GB / T 2518-2019 tus qauv: Raws li qhov zoo ntawm txheej galvanized, nws muab faib ua ntau qib ntawm zinc txheej hnyav (g / m2), xws li Z60, Z80, Z100, thiab lwm yam. Ntawm lawv, Z60 txhais tau hais tias zinc txheej hnyav yog 60 grams / square meter.
2. ASTM A653 / A653M tus qauv: Raws li qhov sib piv ntawm galvanized txheej thickness rau steel phaj thickness (zinc qib), nws muab faib ua G30, G40, G60, G90 thiab lwm qib. Qhov twg G30 txhais tau tias zinc txheej thickness yog 0.3 ooj / square feet.
2. Cov yam ntxwv thiab kev siv ntawm cov ntawv hlau galvanized
Galvanized steel ntawv muaj cov yam ntxwv hauv qab no:
1. Zoo corrosion kuj: Zinc muaj corrosion kuj zoo thiab tuaj yeem tsim cov zinc txheej tsis txuas rau saum npoo ntawm steel phaj, uas plays lub luag haujlwm ntawm kev tiv thaiv zoo thiab kev tiv thaiv zoo nkauj.
2. Kev ua haujlwm zoo: Qhov saum npoo ntawm galvanized steel ntawv yog du thiab yooj yim rau txiav thiab stamp.
3. Kev siv ntau yam: Galvanized steel sheets yog dav siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, hluav taws xob thiab lwm yam kev lag luam, xws li ru tsev panels, phab ntsa vaj huam sib luag, cov khoom siv hauv tsev, cov khoom siv hauv tsheb, cov ncej thiab cov yees, thiab lwm yam.
Cov qib sib txawv ntawm cov ntawv galvanized steel yuav tsum raug xaiv rau cov ntawv thov hauv ntau qhov chaw. Piv txwv li, nyob rau hauv lub tshav pob ntawm kev tsim kho, nws yog tsim nyog los xaiv Z60-Z100 qib galvanized steel los xij nrog thinner thickness los txo qhov hnyav ntawm lub tsev; Hauv kev tsim tsheb, nws yog ib qho tsim nyog yuav tsum xaiv G30-G90 qib galvanized steel nplooj ntawv nrog zinc cov ntsiab lus siab dua kom cov khoom zoo thiab corrosion kuj.
Hauv cov ntsiab lus, kev siv cov qauv kev faib qib thiab cov yam ntxwv ntawm cov ntawv hlau galvanized hauv ntau qhov chaw yog qhov tsim nyog kom nkag siab txog cov ntawv hlau galvanized. Peb cia siab tias cov neeg nyeem tuaj yeem nkag siab zoo dua thiab siv cov ntawv galvanized steel los ntawm kev qhia txog kab lus no.
