Galvanizing yog txheej txheem tsim los pab steel tiv thaiv corrosion thiab muab kev tiv thaiv kom nws zoo li zoo thiab kev ua tau zoo.
Qhov tseeb yog dab tsigalvanized hlau?
Ua ntej peb sib piv lawv, nws yog ib qho tsim nyog yuav tsum nkag siab tias cov hlau galvanized ua li cas.
Qhov tseem ceeb, galvanized steel yog galvanized steel.
Muaj ntau txoj hauv kev ntawm galvanizing steel qhov chaw thiab cov rooj sib txoos, tab sis lawv txhua tus muab cov txiaj ntsig zoo sib xws thaum ua kom raug.
Txoj kev zoo tshaj plaws rau galvanizing steel yog kub dip plating.
Nyob rau hauv cov txheej txheem no, cov qauv hlau yog dipped nyob rau hauv molten zinc, tsim ib txheej zinc uas khi rau saum npoo ntawm cov hlau, muab kev tiv thaiv thiab zoo nkauj tsos.
Yog li ntawd yog galvanized steel li corrosion resistant li stainless hlau?
Feem ntau hais lus, tsis muaj.
Galvanized steel ntawv thiab stainless hlau los xij yog ob yam khoom sib txawv. Lawv txawv ntawm cov hauv qab no:
Cov khoom muaj pes tsawg leeg: Galvanized steel phaj yog ib hom zoo tib yam steel phaj tau los ntawm kub-dip galvanizing ntawm qhov chaw. Cov khoom tseem ceeb yog carbon steel; thaum stainless hlau phaj yog tsim los ntawm hlau, chromium, nickel thiab lwm yam khoom. Nws cov yam ntxwv tseem ceeb yog corrosion kuj, Tsis yooj yim rau xeb.
Corrosion kuj: Stainless hlau daim hlau muaj qhov zoo corrosion kuj thiab tuaj yeem tiv taus qhov yaig ntawm corrosive yam xws li acids, alkalis, thiab ntsev, thaum galvanized steel daim hlau tsis zoo li corrosion-resistant li stainless hlau daim hlau.
Kev pab lub neej: Lub neej kev pab cuam ntawm stainless hlau daim hlau yog ntev tshaj li ntawm galvanized steel daim hlau. Txij li cov hlau tsis muaj steel hlau tau zoo dua corrosion kuj thiab oxidation tsis kam, lawv muaj zog dua nyob rau hauv atmospheric thiab dej ib puag ncig.
Nto gloss: Lub ntsej muag gloss ntawm stainless hlau daim hlau yog qhov siab thiab muaj cov xim hlau zoo nkauj, thaum lub ntsej muag gloss ntawm galvanized steel daim hlau yog qhov tsawg thiab ntxhib.
Xim: Stainless hlau daim hlau muaj ntau yam txheej txheem kho saum npoo uas tuaj yeem ua tiav ntau yam xim thiab cov teebmeem, thaum cov xim ntawm cov hlau galvanized feem ntau yog grey.
