Kev xeb ntxov ntxov ntawm S335J2W Corten Steel thaum lub sijhawm khaws cia - ua ntej ntawm - qhov chaw teeb tsa thiab kev tiv thaiv xeb txheej txheej txheem tsim - tuaj yeem ua rau nws qhov kev ncaj ncees ntawm qhov chaw, cuam tshuam cov xeb txheej txheej, thiab txawm txo qhov ntev - lub sij hawm corrosion kuj. Rau cov neeg yuav khoom, kev nkag siab seb puas yuav tsum muaj kev ntsuas tshwj xeeb los tiv thaiv qhov teeb meem no yog qhov tseem ceeb rau kev khaws cov khoom siv. Txawm li cas los xij, raws li S335J2W tsis yog qib qauv hauv European cov qauv, cov txheej txheem khaws cia tsis muaj. Yuav tsum ua raws li cov kev cai ntseeg tau li cas? Lub ntsiab lus qhia ua ntej:S335J2W tsis tau teev nyob rau hauv EN 10025-5 (lub ntsiab European qauv rau huab cua-resistant steels), tab sis peb tuaj yeem muab cov phiaj xwm khaws cia raws li nws cov khoom pov thawj ( huab cua tsis kam tso siab rau Cu / Cr / P, nruab nrab - tsis muaj zog) thiab EN 10025-5's cia logic rau cov qib Corten Steel zoo sib xws. Hauv qab no yog cov lus qhia luv luv, raws li cov ntaub ntawv pov thawj.
Lub Ntsiab Tseem Ceeb: Qib Nature & Risks Premature Rusting
Txhawm rau kom ntseeg tau tias kev ntsuas kev cia khoom muaj txiaj ntsig thiab muaj txiaj ntsig, ob lub ntsiab lus tseem ceeb yuav tsum tau qhia meej ua ntej:
Qib Inference: S335J2W yog suav tias yog nruab nrab- lub zog qis Corten Steel (yield zog 235-}355MPa) nrog huab cua-cov khoom tiv taus (ib "W" suffix) thiab -20℃cuam tshuam toughness (ib "J2" cov lus xaus), ua raws li EN 10025 steel qauv rau-5's
Risks ntawm Premature Rusting: Tsis zoo li "muaj txiaj ntsig" tiv thaiv xeb tsim tom qab kev teeb tsa, xeb ntxov ntxov (ua los ntawm kev cia tsis raug) yog xoob, ntxeem tau, thiab tsis sib xws. Nws tsis tuaj yeem khi nruj rau lub substrate, thiab thaum raug rau ib puag ncig kev pabcuam tom qab, nws tawm tau yooj yim - nthuav tawm cov substrate kom rov ua dua - corrosion thiab txo cov khoom siv lub neej.
Core Risk Sources ntawm Premature Rusting Thaum khaws cia
Kev cia khoom- cuam tshuam txog kev xeb ntxov ntxov yog tshwm sim los ntawm peb yam, uas yog lub hom phiaj tseem ceeb ntawm kev cia tshwj xeeb:
Tsis tu ncua High Humidity: Kaw, tsis zoo ventilated qhov chaw cia nrog high humidity (Ntau tshaj los yog sib npaug rau 65%) ua rau ya raws nyob rau hauv cov hlau nto, accelerating oxidation.
Ntsev Mist & Pollutant Exposure: Kev khaws cia ze rau thaj chaw ntug dej hiav txwv lossis thaj chaw muaj kev lag luam nthuav tawm cov hlau rau ntsev ions lossis tshuaj lom neeg ua paug, uas ua rau lub zos pitting corrosion.
Deg Contamination & Tiv tauj Corrosion: Roj, plua plav, lossis lwm yam khoom paug ntawm qhov chaw, lossis kev sib cuag ncaj qha nrog cov hlau tsis muaj - huab cua - cov hlau tsis muaj zog (xws li cov pa roj carbon zoo tib yam) lossis cov ntaub ntawv ntub dej (xws li, cov ntoo tsis muaj caij nyoog), ua rau tsis sib xws.
Tshwj xeeb cia yuav tsum tau los ntawm Scenario
Kev ntsuas kev khaws cia tsom mus rau kev cais cov peev txheej, tswj xyuas qhov ziab kom qhuav, thiab zam kev sib kis- yooj yim, qis- tus nqi, thiab ua raws li EN 10025-5's Corten Steel cov ntsiab cai khaws cia:
1. Kev Cia Hauv Tsev (Rau Pom Zoo rau Ntev- Lub Sij Hawm Cia Ntau dua lossis sib npaug li 1 Lub Hlis)
Environment Control: Xaiv qhov chaw qhuav, zoo- lub tsev khaws khoom cua nrog cov av noo tsawg dua lossis sib npaug li 60%. Nruab cov dehumidifiers yog tias xav tau (tshwj xeeb tshaj yog nyob rau lub caij los nag lossis siab - thaj chaw av). Xyuas kom tsis txhob muaj hluav taws xob ncaj qha (uas ua rau qhov kub thiab txias thiab condensation) thiab tsis raug rau cov pa taws.
Kev tiv thaiv nto: Npog cov ntawv S335J2W uas tsis muaj txheej txheem nrog VCI (Volatile Corrosion Inhibitor) zaj duab xis- tsis txhob airtight yas zaj duab xis (cua noo). Rau ua ntej -rusted S335J2W, siv nplooj siab breathable los tiv thaiv- xeb daim ntawv los khaws cov txheej txheem xeb thawj zaug.
Stacking & Kev rho tawm: Place steel sheets on elevated, moisture-proof supports (e.g., concrete blocks or ISPM 15-compliant fumigated wooden pallets) with a height ≥10cm above the ground. Use rubber or Corten-compatible plastic pads between layers to avoid direct metal-to-metal contact. Do not stack too high (≤3 layers for thick-gauge sheets >15mm) los tiv thaiv deformation deformation lossis zaj duab xis puas.
2. Kev cia sab nraum zoov (tsuas yog luv luv- Lub Sijhawm Cia Tsawg dua lossis sib npaug li 1 Lub Hlis)
Xaiv qhov chaw: Xaiv ib qho chaw tiaj tus, zoo- thaj chaw uas ntws tawm ntawm ntug dej hiav txwv ntsev, cov chaw tso pa tawm, thiab qhov chaw dej. Zam kom tsis txhob muaj - thaj chaw pw uas cov dej nag los.
Huab cua tiv thaiv: Npog tag nrho pawg nrog marine - qib waterproof, UV- ntaub woven resistant. Khaws daim ntaub kom nruj nrog cov hlua khi thiab kaw tag nrho cov seams nrog cov ntaub ntawv tsis muaj dej kom tiv thaiv cov dej los nag. Tilt cov pawg me ntsis (3-5 degree) kom pab txhawb cov dej nag thiab tsis txhob tso dej rau ntawm qhov chaw.
Txhim kho kev cais tawm: Siv cov kev txhawb nqa siab dua (Ntau dua lossis sib npaug li 20cm saum av) txhawm rau tiv thaiv cov av noo noo los ntawm kev tiv thaiv cov hlau. Tsis txhob khaws cia ze cov pa roj carbon zoo tib yam, cov chiv, lossis lwm yam khoom siv corrosive.
Tseem Ceeb Cia "Tsis Txhob" & Cov Ntawv Tshawb Xyuas Kev Tshawb Fawb
Key "Tsis txhob": ① Tsis txhob siv cov yas yas airtight rau ntev - lub sij hawm cia (cua ya raws thiab ua rau xeb sai); ② Tsis txhob muab S335J2W ncaj qha rau hauv av lossis ntub ntoo pallets; ③ Tsis txhob ntxuav lub ntsej muag nrog cov kua qaub / alkaline ntxuav ua ntej cia (ua puas rau thawj txheej oxide); ④ Tsis txhob khaws cia rau hauv qhov chaw uas muaj qhov kub thiab txias tsis tu ncua (induces condensation).
Kev tshuaj xyuas tsis tu ncua (Lub Limtiam rau Sab Nraud, Bi-Lub Limtiam rau Sab Hauv Tsev): Txheeb xyuas qhov sib xyaw ua ke, dej seepage, lossis xoob npog; tshuaj xyuas cov hlau nto rau qhov txawv txav (xws li xeb liab, pitting); xyuas kom meej tias kev txhawb nqa tsis ntub lossis deformed. Yog tias pom muaj xeb txawv txav, tshem tawm cov kab mob hauv qhov chaw nrog cov txhuam txhuam mos thiab rov siv VCI zaj duab xis.
Hauv cov ntsiab lus, khaws cia S335J2W Corten Steel los tiv thaiv kev xeb ntxov ntxov yuav tsum tau ntsuas kev ntsuas raws li lub sijhawm khaws cia (sab hauv tsev rau lub sijhawm ntev -, sab nraum zoov rau luv - lub sijhawm), tsom rau kev tswj cov dej noo, kev tiv thaiv saum npoo, thiab kev sib cais ntawm cov kab mob. Cov kev cai no tau muab los ntawm EN 10025-5's Corten Steel cia logic. Rau kev ntseeg tau, paub meej tias S335J2W qhov tseeb ntawm qhov chaw thiab cov khoom siv nrog cov neeg muag khoom (ntawm Cov Ntaub Ntawv Cov Ntaub Ntawv) thiab kho cov ntsuas ntsuas raws li.
