Galvanized Steel yog dab tsi
Galvanized steel yog carbon hlau uas nqa cov zinc txheej siv los ntawm kub-dip galvanizing, electro-galvanizing lossis txuas txuas txuas galvanizing. Cov hlau muab lub zog thiab khov kho, thaum zinc muab kev tiv thaiv corrosion los ntawm kev cuam tshuam thiab kev tiv thaiv kev txi. Tib txoj cai siv rau galvanized yeeb nkab, galvanized ntawv, galvanized hlau thiab galvanized structural seem, uas yog vim li cas cov khoom tshwm nyob rau hauv ntau yam kev lag luam nyob rau hauv ib lub npe.
Kev siv ntawm Galvanized Steel Yeeb Nkab
| Daim ntawv thov | Yam khoom | Yog vim li cas galvanized steel siv |
|---|---|---|
| Kev xa dej thiab kev tso dej | Galvanized welded steel yeeb nkab rau GB / T 3091 lossis ASTM A53 | Sab hauv thiab sab nraud corrosion kuj rau qhov qis - nqi nruab qhov system |
| Hluav taws kub sib ntaus sib tua thiab sprinkler kab | Kub-dip galvanized yeeb nkab, qee zaum nrog cov xim tiav | Cov txheej txheej sab nraud tiv thaiv cov nroj tsuag huab cua thiab cov txheej sab hauv txwv tsis pub muaj kev xeb hauv cov dej sawv ntsug |
| Cov qauv framing thiab kev txhawb nqa | Galvanized hollow seem rau EN 10219-1 lossis ASTM A500 | Kev tu- kev ua haujlwm sab nrauv pub dawb rau thav duab, canopies thiab platforms |
| Agricultural systems | Galvanized yeeb nkab rau irrigation, tsiaj txhu penning thiab tsev xog paj thav ntawv | Resistance rau av, chiv thiab manure raug tus nqi qis |
| Fencing, rooj vag thiab guardrails | Galvanized raj thiab ntu | Lub neej ua haujlwm ntev uas tsis tas yuav tsum tau pleev xim rau hauv cov haujlwm raug pom |
| Cua sov thiab cua ducting | Galvanized ntawv | Corrosion tiv thaiv rau zais thiab humid ductwork |
Galvanized Sheet thiab cov khoom tsim qauv
Cov ntawv txuas ntxiv galvanized tau teev tseg feem ntau los ntawm cov txheej txheem txheej txheem uas qhia tag nrho cov zinc loj ntawm ob qhov chaw. ASTM A653 siv cov npe xws li G90, uas sib haum rau tag nrho cov txheej txheej ntawm li 275 g / m2, G60 ntawm li 180 g / m2 thiab G40 ntawm txog 120 g / m2, nrog rau cov qauv thiab cov qib ntawm cov hlau hauv paus. Daim ntawv yog siv rau ducting, vov tsev thiab cladding, cov khoom siv thiab cov khoom vaj tse, thiab rau yob{12}} cov seem tsim. Heavier kub-dip galvanized structural steel ua raws li ASTM A123 lossis ISO 1461, qhov txheej txheej thickness yog graded los ntawm cov khoom tuab kom cov seem tuab tau txais cov txheej hnyav dua.
Kev siv dej thiab siv tau
Galvanized steel yeeb nkab yog keeb kwm cov khoom siv rau kev siv dej hauv tsev, thiab nws tseem siv dav rau cov dej tsis huv, dej ntws, cua txias thiab tiv thaiv hluav taws. Rau cov dej haus, txoj hauj lwm yog txawv: raws li cov zinc txheej tau noj, lub sab hauv deg corrodes, ua xeb deposits uas txo cov bore zoo, nce siab poob thiab yuav cuam tshuam rau dej zoo. Vim li no ntau lub tsev lis dej num tsis tso cai tshiab galvanized steel yeeb nkab nyob rau hauv potable dej systems, thiab tsim yuav tsum ua raws li cov kev cai hauv zos. Qhov twg cov yeeb nkab galvanized tseem nyob rau hauv kev pab cuam hauv lub peev xwm, kev saib xyuas mob thiab hloov qhov tshwm sim yuav tsum tau npaj es tsis txhob ncua.
Kev xaiv thiab Fabrication Notes
Sib txuam txheej txheej rau ib puag ncig es tsis qhia meej galvanized general, thiab hais cov qauv uas txhais qhov tsawg kawg nkaus.
Tso cai rau qhov tseeb tias txiav, xov thiab vuam tshem tawm cov txheej txheem, thiab npaj rau zinc- nplua nuj kho ntawm txhua qhov chaw qhib.
Kho qhov chaw galvanized nrog qhov tseeb etchant ua ntej pleev xim, vim tias tsis kho zinc tiv taus cov primers tsis zoo.
Cais galvanized hlau los ntawm tooj liab, stainless hlau nyob rau hauv tej yam kev mob, thiab lwm yam hlau sib txawv los tswj galvanic corrosion.
Saib xyuas qhov kub ntawm cov txheej txheem tom ntej: qhov ntev ntawm qhov txias txias - tsim siab - lub zog rau qhov kub siab tuaj yeem cuam tshuam rau lawv cov khoom siv kho tshuab.
FAQ
Q: Dab tsi yog galvanized steel siv rau feem ntau?
Nws cov kev siv loj tshaj plaws yog cov kav dej thiab cov kav dej, cov txheej txheem framing thiab hollow seem, fencing thiab guardrails, tsev cog khoom thiab cov khoom siv ua liaj ua teb, cua sov thiab cua ducting, thiab cov khoom siv sab nraum zoov uas yuav tsum tiv taus huab cua tsis tu ncua.
Q: Puas yog galvanized steel muaj kev nyab xeeb rau cov dej haus?
Galvanized steel yog cov khoom siv ib txwm siv rau kev tsim cov dej hauv tsev, tab sis nws tsis pom zoo rau cov khoom siv dej tshiab hauv ntau qhov chaw txiav txim vim tias cov txheej txheem tau noj dhau sijhawm thiab qhov chaw sab hauv tuaj yeem corrode. Cov kev cai hauv zos yuav tsum ua raws.
Q: Yuav ua li cas galvanized steel piv nrog stainless hlau?
Galvanized steel nqi tsawg dua thiab muaj kev tiv thaiv zoo hauv kev pabcuam huab cua. Stainless hlau tiv thaiv corrosion zoo dua nyob rau hauv chlorides, acids thiab siab - purity daim ntaub ntawv, yog li qhov kev xaiv nyob ntawm ib puag ncig, kev pab cuam lub neej thiab nyiaj txiag ntau dua li ntawm ib qho khoom ua tau zoo dua.
Q: Can galvanized steel welded?
Yog lawm, tab sis cov zinc yuav tsum tau muab tshem tawm ntawm thaj chaw sib koom ua ke, kev tshem tawm cov pa tawm kom txaus yog qhov tseem ceeb, thiab thaj chaw welded thiab cov txheej txheej puas tsuaj yuav tsum tau kho tom qab nrog zinc- nplua nuj txheej los tiv thaiv corrosion.
Q: G90 npe rau ntawm daim ntawv galvanized txhais li cas?
Nws yog ASTM A653 txheej txheej uas hais txog tag nrho cov zinc txheej loj ntawm ob qhov chaw, qhov no kwv yees li 275 g / m2. Cov qauv siab dua qhia tias cov txheej txheej hnyav dua thiab lub neej corrosion ntev dua.
Q: Yuav ua li cas galvanized steel yuav khaws cia rau ntawm qhov chaw?
Khaws kom qhuav, tawm hauv av thiab sib cais nrog ntoo lossis yas dunnage kom huab cua tuaj yeem ncig. Ntev -lub sij hawm raug rau cov dej sawv ntsug los yog cov khoom ntub dej ua rau cov xeb dawb ntawm zinc nto thiab yuav tsum zam.
