Xaiv ntawmgalvanized steel thiab txias dov steelyog ib qho kev txiav txim siab tshaj plaws engineers fim thaum qhia cov ntaub ntawv rautag nrho - cov rooj zaum steel. Kev nkag siab txog qhov sib txawv ntawm kev tiv thaiv corrosion, weldability, nto tiav, thiab cov khoom siv kho tshuab pab cov neeg yuav khoom xaiv cov khoom siv zoo rau cov rooj tog zaum, cov rooj zaum ua haujlwm, thiab cov khoom ntim khoom. Hauv qab no, peb rhuav tshem cov kev faib tawm, cov yam ntxwv, thiab cov tswv yim xaiv cov tswv yim rau ob qho tib si electrolytic galvanized steel ntawv thiab txias dov steel phaj.
1. Galvanized Steel Sheet yog dab tsi?
Galvanized steel ntawv hais txog ib daim ntawv hlau coated nrog ib txheej ntawm zinc rau ntawm qhov chaw. Galvanizing yog ib qho kev lag luam thiab siv tau zoo los tiv thaiv- xeb txoj kev uas feem ntau siv los tiv thaiv corrosion ntawm cov phaj steel thiab txuas nws lub neej kev pab cuam.
Kev faib tawm ntawm Galvanized Steel Sheets
① Kub-Dip Galvanized Steel Sheet
Cov hlau nyias nyias yog immersed nyob rau hauv lub molten zinc da dej, tso cai rau ib txheej ntawm zinc mus rau saum npoo. Niaj hnub no, nruam galvanizing yog cov txheej txheem tsim khoom tseem ceeb - dov steel ntawv txuas ntxiv dhau los ntawm galvanizing da dej ntawm molten zinc los ua kub -dip galvanized steel ntawv.
Kub-dip galvanized steel muaj qhov zoo dua ntawm electro-galvanized steel: electro-galvanized steel nyiam xeb yooj yim ntawm khoov thiab txiav npoo, thaum kub-dip galvanized steel muaj ntau zoo xeb kuj nyob rau hauv tib yam kev mob. Hauv peb qhov kev paub txog kev muab cov khoom siv rau cov khoom lag luam, siab - cov ntaub ntawv zoo feem ntau qhia cov electrolytic lossis kub -dip galvanized steel daim hlau, txij li cov khoom ua los ntawm cov khoom no muaj lub teeb ci, nws yog xim hlau-lustered nto nrog rau kev tiv thaiv corrosion.
Kub-dip galvanized steel feem ntau yog ntau dua corrosion-resistant dua li txias-rolled steel. Nws cov yam ntxwv tseem ceeb yog muaj zog corrosion kuj, zoo nto zoo, thiab haum rau kev sib sib zog nqus ua ntawm tus nqi tsim nyog. Uas tau hais tias, nws qhov kev kos duab (sib sau) kev ua tau zoo tsis yog qhov kev ntseeg siab zoo li txias -rolled steel, thiab nws nyuaj rau welding, txij li cov vuam feem ntau ua rau cov zinc txheej.
② Alloyed Galvanized Steel Sheet
Cov phaj hlau no kuj yog tsim los siv cov txheej txheem kub -dip, tab sis tam sim ntawd tom qab tawm hauv cov zinc da dej nws rov ua kom sov li ntawm 500℃los tsim cov yeeb yaj kiab ntawm zinc thiab hlau. Hom ntawv galvanized no muaj cov txheej txheem zoo adhesion thiab txhim kho weldability - ib qho kev xaiv zoo rau cov fabricators uas xav tau ob qho tib si tiv thaiv corrosion thiab yooj yim weld pob qij txha.
③ Electro-Galvanized Steel Sheet
Ua los ntawm electroplating, no galvanized steel ntawv muaj kev ua haujlwm zoo. Txawm li cas los xij, zinc txheej yog thinner, yog li nws cov corrosion kuj yog qis dua kub -dip galvanized ntawv - uas yog vim li cas kub - dip galvanized ntawv tseem yog qhov kev xaiv ntau dua rau cov rooj zaum zaum. Electro-galvanized steel feem ntau yog siv hauv cov khoom siv hauv tsev, cov ntaub ntawv hauv computer, thiab qee qhov rooj vaj huam sib luag.
④ Ib qho -Sided thiab Ob Chav -Sided Differential Galvanized Steel Sheet
Ib leeg-sab galvanized steel ntawv yog galvanized ntawm ib sab xwb. Nws muaj kev hloov pauv tau zoo dua li ob - sab galvanized ntawv thaum lub sij hawm vuam, pleev xim, tiv thaiv- xeb, thiab kev ua haujlwm dav dav. Txhawm rau hais txog qhov tsis zoo ntawm tsis muaj zinc txheej ntawm ib sab, cov tuam ntxhab kuj tsim cov ntawv sib txawv galvanized nrog cov zinc txheej nyias siv rau sab tsis muaj coated.
⑤ Alloy thiab Composite Galvanized Steel Sheet
Hom no sib txuas zinc nrog lwm cov hlau - xws li txhuas lossis txhuas - los ua cov hlau alloy lossis cov hlau sib xyaw. Nws muab kev tiv thaiv zoo tshaj - xeb kev ua tau zoo nrog rau cov txheej txheem zoo, ua rau nws muaj kev xaiv zoo rau kev xav tau kev lag luam ib puag ncig.
Tshaj li tsib pawg no, kuj tseem muaj xim -coated galvanized steel los xij, luam tawm -cov ntawv galvanized, thiab PVC- laminated galvanized steel los xij. Tseem, kub-dip galvanized ntawv tseem yog qhov kev xaiv dav tshaj plaws hauv kev xyaum.
2. Dab tsi yog Cold Rolled Steel?
Txias dov steel yog tsim los ntawm txias dov - txheej txheem uas ntxiv thins ib daim hlau mus rau lub hom phiaj thickness ntawm chav tsev kub. Piv nrog rau kub- dov steel daim hlau, txias- dov steel ntawv muaj ntau yam thickness tswj, ib tug smoother thiab zoo nkauj nto, thiab superior mechanical zog, tshwj xeeb tshaj yog nyob rau hauv kev ua tau zoo. Vim tias txias-rolled raw coils zoo li nkig thiab tawv, txias-rolled steel ntawv feem ntau yuav tsum tau annealing, pickling, phosphating, thiab nto smoothing ua ntej ua ntxiv.
Cold Rolled Steel vs Kub Rolled Steel
Qhov sib txawv tiag tiag ntawm txias- dov thiab kub- dov steel yog tsis nyob rau hauv cov txheej txheem smelting tab sis nyob rau hauv dov kub - tshwj xeeb, qhov kawg dov (tiav) kub. Thaum qhov kub no poob qis dua cov hlau recrystallization kub, qhov tshwm sim yog txias dov hlau.
Kub- dov steel yog yooj yim dua thiab ua tau zoo dua rau yob, tab sis qhov siab - txheej txheem kub oxidizes hlau, tawm hauv qhov chaw tsaus thiab grey. Txias- dov steel, los ntawm qhov sib piv, xav tau ntau dua dov zeb zog thiab qis dua dov. Intermediate annealing tseem yuav tsum tau tshem tawm kev ua haujlwm nyuaj thaum dov, uas ntxiv rau cov nqi tsim khoom. Nyob rau hauv kev sib pauv, txias-rolled steel xa cov ci ntsa iab thiab txhim khu kev qha zoo uas tau npaj rau kev ua tiav ncaj qha rau hauv cov khoom tiav - uas yog vim li cas cov nplooj ntawv txias txias tau siv dav hauv kev lag luam.
Txias- cov ntawv dov yog qhov tseem ceeb kub- cov ntawv dov uas tau dhau los ntawm qhov txias ntxiv - nias. Tom qab ntau lub caij txias dov, qhov zoo ntawm qhov chaw zoo tuaj yeem pom zoo piv rau cov ntawv kub -rolled, thiab kev kho cua sov tuaj yeem txhim kho cov khoom siv kho tshuab.
3. Galvanized Steel vs Cold Rolled Steel: Yam Koj Yuav Tsum Xaiv?
Nyob rau hauv cov nqe lus ntawm corrosion kuj nyob rau hauv sib npaug zos tej yam kev mob,galvanized steel ntawv zoo tshaj qhov txias -rolled steel ntawv. Cov zinc txheej ntawm cov ntawv galvanized yog tsim tshwj xeeb los tiv thaiv oxidation thiab corrosion, thaum txias - dov steel ntawv - tsis muaj txheej tiv thaiv - yuav oxidize thiab xeb ntau dua thaum raug huab cua.
Ntawm qhov tod tes, cov ntawv txias- dov feem ntau muab cov tuab tuab zoo dua thiab muaj zog dua. Rau cov ntawv thov uas xav tau qhov siab tshaj plaws corrosion tsis hais tus nqi, zinc alloys thiab stainless hlau muab kev tiv thaiv zoo dua li cov ntawv galvanized, txawm tias lawv cov nqi ntau dua.
Nws tseem tsim nyog sau cia tias cov khoom siv hauv paus ntawm galvanized steel ntawv feem ntau yog txias - dov los yog kub - dov daim ntawv - lub ntsiab lus galvanized steel inherits qee qhov kev txwv ntawm nws cov hlau puag. Nws qhov kev ua tau zoo ntawm kev kos duab tsis zoo li qhov txias txias -rolled steel, thiab nws nyuaj rau vuam kom huv si, txij li kev vuam ua rau cov zinc txheej.
Cov tswv yim xaiv tswv yim rau cov neeg yuav khoom B2B
Xaiv kub -dip galvanized steelrau sab nraum zoov, ntub dej, lossis corrosive ib puag ncig uas ntev - lub sij hawm xeb kuj yog qhov tseem ceeb - feem ntau nyob rau hauv cov rooj zaum sim, cov ntaub thaiv sab nraum zoov, thiab cov khoom siv raug hloov pauv.
Xaiv cov hlau txias txiasThaum qhov tseeb qhov ntev kam rau ua, lub zog muaj zog, thiab yooj yim ntawm vuam teeb meem ntau dua li ua -hauv kev tiv thaiv corrosion - tshwj xeeb tshaj yog tias cov khoom tiav lawm yuav pleev xim los yog hmoov-coated tom qab.
Xaiv electro-galvanized steelrau kev siv sab hauv tsev xws li cov khoom siv vaj tse lossis cov vaj huam sib luag uas muaj kev tiv thaiv corrosion thiab kev ua haujlwm zoo txaus txaus.
Xav txog cov alloy lossis cov ntawv sib xyaw galvanizedrau kev thov kev lag luam chaw uas xav tau ob qho tib si muaj zog tiv thaiv- xeb kev ua tau zoo thiab txhim khu kev qha txheej zoo.
Rau cov chaw tsim khoom lag luam thiab cov chaw tsim khoom siv rooj tog zaum, cov khoom siv zoo xaiv feem ntau los ntawm qhov chaw ua haujlwm, kev siv nyiaj txiag, thiab seb puas muaj kev kho deg ntxiv (thaum xim, hmoov txheej) yuav raug siv tom qab tsim.
