TusCorrosion Kuj Siv Hluav Taws Xob Ntawm S3555J0WP Weathering Hlauyog feem ntau raws li kev tsim ntawm aTiv thaiv txheej xeb(patina) ntawm nws cov npoo thaum uas raug rau cov huab cua. Qhov kev tiv thaiv tus kheej tiv thaiv nws qhov txawv ntawm cov hlau ua hlau. Ntawm no yog cov ncauj lus kom ntxaws ntawm lub tshuab:
1. Cov ntsiab lus txhawb nqa txhawb kev tiv thaiv xeb tiv thaiv
S3555J0WP muaj cov me tab sis tseem ceeb ntxiv ntawmAlloying Ntsiab(feem ntauCU, P, CR, NI), uas ua si lub luag haujlwm tseem ceeb hauv xeb ruaj khov:
Tooj Liab (Cu)thiabChromium (cr): Ua kom nrawm qhov tsim ntawm qhov ntom ntom, cov txheej txheem xeb.
Phosphorus (p): Txhim kho corrosion tsis kam los ntawm kev txhawb nqa txoj kev tsim cov teb ruaj khov hauv cov xeb.
Npib tsib caug (ni): Txhim kho kom tsis kam mus rau chloride-induced corrosion (piv txwv li, hauv ntug hiav txwv ib puag ncig).
Cov ntsiab lus no pab txhawb txoj kev loj hlob ntawm aKev Cog Lus, Ruajxes Oxide TxheejHloov chaw ntawm lub ntxeem tau, flaky xeb pom hauv cov hlau zoo tib yam.
2. Kev tsim ntawm cov tiv thaiv patina
Thaum raug rau ntub dej / qhuav mus txog hauv cov huab cua, cov hlau tawg cov theem hauv qab no:
a. Pib xeb (thawj 1-2 xyoos)
Cov xoob xoob, liab-xim av xeb txheej (zoo ib yam li cov hlau hlau).
Electrochemical corrosiontshwm sim, tab sis alloying cov ntsiab qeeb cov txheej txheem.
b. Ntu kauj ruam (tom qab ~ 2-5 xyoos)
Cov kab xeb zuj zus hloov mus rau hauvntom, tiv thaiv PatinaVim yog alloy hais.
Cov tebchaw tseem ceeb hauv qhov ruaj khov muaj xws li:
Goeesrite (-Feooh)- Muab ib txoj kev thaiv kev tawm tsam cov pa oxygen ntxiv / noo noo.
Lepidocrocite (-Feooh)- Cov ntaub ntawv pib tab sis hloov siab los hloov theem ntau dua.
Amorphous (feooh · nhh₂o)- Ua cov khoob hauv cov xeb xeb.
CU / Cr-nplua nuj theem- Ntxiv inhibit corrosion los ntawm thaiv cov chaw nquag.
c. Lub sijhawm ntev
Cov xeb xeb uatus kheej kev txwv(nres kev loj hlob dhau ib qho tuab tuab).
Nws ua raws li aDiffusion Teeb Meem, tiv thaiv cov pa oxygen ntxiv thiab cov dej nkag.
3. Qhov tseem ceeb yam cuam tshuam txog kev siv tshuab
Ntub / qhuav cycling: Hloov qhov raug rau noo noo thiab huab cua nrawm ua kev tsim.
Cov Hluav Taws Xob Huab Cua:
Kev lag luam / Nroog (So₂-nplua nuj): PATINY cov ntaub ntawv sai dua tab sis yuav xav kom muaj kev ruaj khov ntau.
Tubrog Hlav (Cl⁻-nplua nuj): Kev pheej hmoo siab ntawm pitting; Ni / CR Pab Thov txo cov tshuaj chloride.
Nyob deb nroog (huv): Qeeb qeeb tab sis ntau yam tsis zoo xeb ruaj khov.
pyr cawv: Cov txheej xeb yog ruaj khov dua hauv cov pa qaub me ntsis rau nruab nrab.
4. Kev sib piv nrog cov hlau ua paug
| Yam zoo | S355J0WP Weathering Hlau | Cov Khoom Siv Carbon Txawv Hlau |
|---|---|---|
| Rust txheej | Ntom, adherent, tiv thaiv | Ntxig, flaky, tsis tiv thaiv |
| Corrosion tus nqi | Tso cai tom qab pib theem | Tsis tu ncua nce |
| Kho | Tsawg kawg (feem ntau siv tsis tau) | Yuav tsum tau coasters / Painting |
| Lub neej | 2-4 × ntev nyob rau hauv kev xeb ib puag ncig | Luv luv, prone rau thinning |
5. Cov tswv yim cuam tshuam
Tsis tas yuav pleev xim: Lub Patina tshem tawm qhov xav tau ntawm cov txheej txheej hauv ntau cov ntawv thov (piv txwv li, txuas hniav, facades).
Kev Thov Kom Zoo Nkauj: Lub ruaj khov xeb txheej muab qhov sib txawv liab-xim av tsos.
Kev txwv:
Tsis haum rautas li imperersion(xws li, underwater qauv).
HauvHigh-chloride ib puag ncig(Xws li, ntug dej hiav txwv txaws thaj chaw), yuav tsum muaj kev tiv thaiv ntxiv.
