Dab tsi yog Galvanized steel?

Dab tsi yog Galvanized steel?
A: Galvanized steel yog ib txheej hlau coated nrog zinc txheej rau saum npoo ntawm cov khoom txias, los ntawm cov txheej txheem xws li kub- dip galvanizing lossis electroplating. Nws cov haujlwm tseem ceeb yog txhawm rau txhim kho cov corrosion tsis kam ntawm cov khoom siv hauv paus thiab txuas ntxiv nws lub neej pabcuam.
Dab tsi yog cov tseem ceeb ntawm cov hlau galvanized?
A: Nws muaj feem ntau ntawm ob ntu: cov khoom siv hauv paus (feem ntau yog zinc hlau, xws li zinc alloy, xws li zinc {}}}}} magnesium alloy).
Dab tsi yog qhov tseem ceeb sib txawv ntawm galvanized steel thiab dog dig txias - rolled steel?
A: Cov tub ntxhais sib txawv nyob hauv "Txheej Txheem Txheej Txheem" ​​{}}} Rust txheej thiab yog yooj yim xeb los ntawm oxidation ntawm cov hlau cov khoom siv. Galvanized steel kev vam khom rau "kev tiv thaiv anodic" thiab "kev sib cais ntawm zinc thiab yog qhov haum rau cov kev siv dav dav (xws li ntug dej sab nraud).
Dab tsi yog cov xim xim ntawm cov hlau galvanized?
A: Cov xim raug yog "nyiaj - grey" (lub ntuj xim ntawm cov ntshiab zinc txheej). Kev kho mob passivation yuav tsim cov xim dhau los ua xim "(zaj sawv xim ua kom tau zoo dua) lossis" xim dub passivation xim "(rau cov hom phiaj zoo nkauj). Tom qab ntev -} sij hawm} ntu kev raug, nws yuav tshwm dawb (dawb xeb) lossis grey tsaus (ruaj khov rau zaj duab xis).
Dab tsi yog "zinc txheej hnyav" ntawm cov ntawv galvanized txhais tau?
A: Nws hais txog qhov nyhav ntawm zinc ib cheeb tsam ntawm lub galvanized ntawv nto. Nws yog qhov taw qhia tseem ceeb rau kev ntsuas cov tuab ntawm zinc txheej ntawm zinc txheej thiab yog ntsuas hauv g / m² (ib qho los yog ob qho tib si- ob sab). Piv txwv li, "80g / m² ob npaug-}}}} ob txhais tau tias 80g ntawm zinc ib square meter ntawm txhua sab. Lub thicker lub zinc txheej, qhov ntau dua qhov xeb tsis kam.
