Rau cov haujlwm hauv thaj chaw muaj kev lag luam hauv av, cov kws tshaj lij thiab cov kws tshaj lij feem ntau nug txog qhov muaj peev xwm ntawm liab qab, tsis pleev xim rau S355J2W Corten Steel. Lub cim, tus kheej - tiv thaiv xeb patina yog qhov txaus siab, tab sis nws yuav tiv thaiv ib puag ncig nrog rau qib siab ntawm huab cua thiab kev lag luam poob?
Kab lus no muab qhov tseeb saib ntawm kev pabcuam lub neej ntawm S355J2W hauv cov chaw zoo li no thiab qhia txog cov ntsiab lus tseem ceeb los xyuas kom meej tias nws lub sijhawm ua haujlwm ntev -.
Corten Steel tiv thaiv nws tus kheej li cas
S355J2W Corten Steel's durability stems los ntawm nws lub peev xwm los tsim ib tug ruaj khov, adherent xeb patina. Tsis zoo li cov hlau zoo tib yam, qhov twg xeb flakes tawm thiab nthuav tawm cov hlau tshiab kom ntxiv corrosion, Corten's alloying ntsiab (xws li tooj liab, chromium, thiab npib tsib xee) txhawb kev tsim cov txheej tuab, tiv thaiv oxide.
Cov txheej no ua raws li kev thaiv, ua kom qeeb ntawm corrosion. Qhov tseem ceeb, cov txheej txheem no yuav tsum tau hloov cov voj voog ntub thiab qhuav; lub patina tsis tuaj yeem tsim lossis tswj nws tus kheej yog tias cov hlau tsis tu ncua los yog ntub dej.
Lifespan nyob rau hauv Inland Industrial Ib puag ncig: Kev Pom Zoo
Lo lus "kev pab cuam lub neej" yog intrinsically txuas mus rau lubpoob ntawm cov khoom thicknessdhau sijhawm. Cov ntaub ntawv los ntawm qhov ntev - kev tshawb fawb txog kev raug mob ua rau pom tseeb tias Corten ua haujlwm li cas hauv cov huab cua sib txawv.
Cov lus hauv qab no qhia txog qhov raug corrosion tsis zoo nyob rau lub sijhawm, sib piv ib puag ncig. Cov chaw muaj kev lag luam nthuav tawm cov xwm txheej nyuaj dua li qhov chaw nyob deb nroog lossis nroog.
| Ib puag ncig | Tej yam kab mob sib kis | Qhov nruab nrab Corrosion poob (thawj 10 xyoo) | Qhov Nruab Nrab Corrosion Loss (Lub Sij Hawm Tom Qab 10-xyoo) |
|---|---|---|---|
| Inland Industrial | High sulfur dioxide (SO₂), chlorides, tshuaj fumes | 0.20mm (8 hli) | 0.10 hli (4 hli) |
| Nroog (Moderate Pollution) | Sulfur dioxide | 0.20mm (8 hli) | ~ 0.05 hli (2 hli) |
| Nyob deb nroog (Clean Air) | Cov pa phem tsawg | 0.10 hli (4 hli) | ~ 0.05 hli (2 hli) |
Cov ntsiab lus tseem ceeb rau kev tsim:
Thawj Corrosion: Thawj xyoo caum pom cov khoom poob siab tshaj plaws raws li kev tiv thaiv patina tsim nws tus kheej.
Ntev -Tsev Sij Hawm: Thaum stabilized, tus nqi corrosion nyob rau hauv ib cheeb tsam muaj kev lag luam txuas ntxiv ntawm ib qho chaw ruaj khov, kev kwv yees tau nrawm. Kev tshawb fawb qhia tias ntev -lub sij hawm khov kho- lub xeev corrosion tus nqi rau huab cua steel ntawm kwv yees li5–6 µm (0.005–0.006 mm) ib xyootom qab lub patina yog tag nrho tsim.
Tsim rau Lifespan: Yog li ntawd, ua tiav lub neej tsim ntawm 50, 80, lossis 120+ xyoo yog qhov ua tau tag nrho. Nws yog ua tiav los ntawm kev ntxiv ib"corrosion pub"mus rau qhov pib thickness ntawm tus tswv cuab steel. Piv txwv li, kom ntseeg tau tias lub nqaj muaj qhov xav tau cov qauv tuab tom qab 50 xyoo hauv thaj chaw muaj kev lag luam, koj yuav tau hais kom nws ua ob peb millimeters tuab dua thaum pib.
Kev Tsim Kho Tseem Ceeb & Kev Saib Xyuas Kev Txiav Txim Siab rau Cov Chaw Lag Luam
Txhawm rau ua tiav qhov kev kwv yees lub neej ntev, tus qauv tsim yuav tsum suav rau cov teeb meem tshwj xeeb ntawm ob qho tib si kev lag luam macro-ib puag ncig thiab cov qauv micro- ib puag ncig.
Yooj yim rau ntub -Dry Cycle: Qhov no yog qhov tseem ceeb tshaj plaws. Kev tsim qauv yuav tsum zam cov cuab yeej dej, ua kom cov dej ntws tawm sai, thiab txhawb nqa huab cua. Cov ntsiab lus uas tso cai rau cov khib nyiab los sib sau los yog ya raws los tuav cov hlau yuav ua rau thaj chaw nrawm dua corrosion.
Tsis txhob ntub dej tsis tu ncua: Cov hlau yuav tsum tuaj yeem qhuav. Cov chaw uas muaj cov av tsis tu ncua, tiv thaiv los ntawm cua thiab hnub, lossis raug tshuaj tsuag ntau zaus tsis haum rau liab qab Corten.
Tswj kom raug ncaj qha rau cov tshuaj lom neeg hnyav: Thaum cov kev txwv huab cua niaj hnub no feem ntau ua kom cov qib SO₂ dav dav nyob rau hauv ib qho kev zam rau Corten, ncaj qha thiab tas li raug rau cov pa taws los ntawm cov vents lossis cov txheej txheem yuav tsum raug zam.
Txhim kho kev ruaj ntseg: Cov txheej txheem yooj yim yog qhov tseem ceeb. Qhov no suav nrogKev tshuaj xyuas thiab tu tsis tu ncuatshem tawm cov av, khib nyiab, thiab cov tshuaj lom neeg tso tawm uas tuaj yeem khaws cov dej noo thiab cuam tshuam patina.
Hauv cov ntsiab lus, liab qab S355J2W Corten Steel tuaj yeem muab lub neej ntev, qis - kev pabcuam kev pabcuam hauv thaj chaw muaj kev lag luam hauv av, nrog rau zoo- cov ntaub ntawv corrosion uas tso cai rau kev ua haujlwm zoo. Tus yuam sij rau kev vam meej yog tsis nyob rau hauv kev cia siab cov khoom yuav ciaj sia, tab sis nyob rau hauvintelligently tsim rau ib puag ncigthiab cog lus rau qhov yooj yim, kev saib xyuas zoo. Los ntawm kev hwm cov ntsiab cai no, Corten tseem yog qhov ruaj khov, kev lag luam, thiab kev xaiv zoo nkauj rau kev tsim vaj tsev.
