S355j2wp corten steel(European qib qib, sib npaugCorten alossisASTM A588) yog siv dav hauv cov choj engineering vim nws zoo heevCorrosion Kuj, lub zog, thiab kav ntevCov. Hauv qab no yog cov ncauj lus kom ntxaws tshuaj xyuas ntawm nws daim ntawv thov cuam tshuam hauv Choj cov dej num:
1. Cov ntsiab lus tseem ceeb hauv Choj Engineering
(1) Zoo siab corrosion tsis kam
Ntuj Tiv Thaiv Txhuam Txheej:
Cov qauv ntom ntom, tus kheej kho oxide txheej thaum nthuav tawm huab cua, txo cov huab cua ntxiv.
Tshem tawm cov kev xav tauPainting los Txheej, txo tus nqi txij nkawm.
Lub neej: {{50+} xyoo nyob deb nroog / nqeg ib puag ncig (vs . 15. 15 - - 25 xyoo rau pleev xim rau cov hlau).
(2) Lub zog siab & hnyav nyiaj
Paib lub zog: 355 MPa (siab dua li cov qauv hlau txheem).
Lub Hnav Txom Nyem: Cov ntu thinner tuaj yeem siv yam tsis muaj peev xwm sib cuam tshuam nrog lub peev xwm, txo cov khoom siv thiab cov nqi siv.
(3) Kev thov kom zoo nkauj
Tsim cov ruaj khov, hnav khaub ncawsXiav-Liab PatinaLub sijhawm dhau los, sib xyaw nrog ntuj ib puag ncig (nrov hauv cov duab kos duab).
(4) muaj peev xwm
Tsis muaj cov tsho lom toxic yuav tsum muaj, txo kev cuam tshuam ib puag ncig ib puag ncig.
100% siv dua tshiab.
2. Cov tswv yim ua tau zoo hauv cov choj
| Yam | Kev ua tau ntawm S3555j2WP | Sib piv rau Cov Hlau Hlau |
|---|---|---|
| Corrosion tus nqi | 0.002-0.005 mm / xyoo (tom qab muaj stabilization) | 0.05-0.1 mm / xyoo (tsis muaj kev tiv thaiv) |
| Kho | Tsawg kawg nkaus (tshuaj xyuas txhua txhua 10-15 xyoo) | Repaint txhua 5-10 xyoo |
| Tus nqi pib | Cov khoom siv siab dua (~ 20% hwm) | Qis dua upfront tus nqi |
| Tus nqi lifecycle | Qi dua(Tsis muaj kev rov pleev xim, tsawg dua kev kho dua tshiab) | Siab dua (npaj siab dua) |
3. Cov kev sib tw & kev ntsuas kev ntsuas
(1) Thaum pib rolloff
Tsab: Xeb staining yuav tshwm sim thaum thawj 1-2 xyoos ua ntej tswj.
Lus teb:
Kev tsim uaLub Nruab Nrab Tshuabkom hloov cov dej ntws tawm.
Kev sivNtseg ib ntuslossis cov hlau ua ntej.
(2) cov chaw hnyav
Tsab: Kev ua yeeb yam tsawg hauv ntug hiav txwv (siab chloride) lossis kev lag luam (siab so) thaj chaw.
Lus teb:
Hybrid Tsim: Cov chaw tseem ceeb (piv txwv li, pob qij txha) tuaj yeem sivStainless hlaulossisCov Khaub Ncaws Tiv Thaiv.
Tu tas li: Tshem tawm ntsev / Sulfur tso nyiaj.
(3) Weldability
Tsab: Yuav tsum kom preheating thiab cov roj av muaj roj av tsawg kom tsis txhob tawg.
Lus teb: Ua rawsEn 1011-2Vuam cov qauv.
4. Tiag tiag-ntiaj teb piv txwv
Yu Laus teb:
MILLA ViaDuct (Fabkis): Weathering steel siv rau kev ua kom zoo nkauj thiab cov txiaj ntsig detability.
UK txoj kev txuas hniav: S35555555j2Wp txo cov nqi kav ntev.
Axias:
Nyiv "Liab Bridge": Qiv lub xeb patina rau kev sib raug zoo nrog kev sib raug zoo nrog kev ua av.
5. Cov lus pom zoo tsim
Zam kev ntxiab dej: Xyuas kom pom kev lom zem kom tiv thaiv kev sib cuag noo noo.
Txo qis kev sib cuag nrog cov ntaub ntawv tsis muaj zog: Tiv thaiv Galvanic corrosion.
Qhia meej cov khaub ncaws ua ntej: Rau cov phiaj xwm yuav tsum tau ua kom ib qho kev ua kom pom tseeb.
