CovS275JR Channelyog lub hauv paus ntawm kev tsim qauv niaj hnub, khoom plig rau nws 275 MPa yield zog thiab tshwj xeeb weldability. Txawm li cas los xij, raws li tsis yog - alloy hlau, nws txoj kev nyuaj tshaj plaws yog oxidation.
S275JR Channel
Thaum tsis muaj kev kho mob saum npoo av, raug rau cov av noo, ntsev, lossis cov khoom ua paug tuaj yeem ua rau cov txheej txheem degradation thiab ua tsis tiav ntxov.
Kev xaiv cov txheej txheej zoo tsis yog kev xaiv zoo nkauj xwb- nws yog qhov kev txiav txim siab uas txiav txim siab txog Kev Lag Luam Rov Qab Los (ROI) thiab kev nyab xeeb ntawm tag nrho cov txheej txheem.
Peb Tus ncej ntawm Corrosion Protection ntawm S275JR Channel
1. Kub-Dip Galvanizing (HDG): Tus Qauv Kub rau Sab Nraud Durability
Kub-dip galvanizing (ua raws li EN ISO 1461) cuam tshuam nrog S275JR channel hauv da dej ntawm zinc molten. Cov txheej txheem no tsim ib daim ntawv cog lus metallurgical, tig cov zinc rau hauv ib feem ntawm cov hlau nto.
Kev Tiv Thaiv Kev Txhaum Cai: Tsis zoo li cov xim, yog tias cov zinc txheej raug khawb, nws yuav "tshem" nws tus kheej los tiv thaiv cov hlau hauv qab los ntawm kev ua haujlwm galvanic.
Qhov zoo ntawm 85μm: Rau cov qauv txheej txheem, txheej txheej tuab ntawm kwv yees li 85 μm muab kev saib xyuas ntau xyoo - kev pabcuam dawb.
| HDG Attribute | Performance Metric |
| Txheej Thickness | 70-100 μm (Nruab nrab 85 μm) |
| Kev Pabcuam Lub Neej | 25–{1}} xyoo nyob rau hauv C3/C4 ib puag ncig |
| Kev tu | Zero rau tsawg heev |
| Zoo tshaj rau | Cov dej num ntawm ntug dej hiav txwv, hnub ci mounting, thiab nthuav tawm infrastructure |
2. Kev Txhaum Txhaum Cai (SA2.5): Engineering qhov profile zoo meej
Rau cov haujlwm uas yuav tsum tau ua haujlwm siab -kev ua haujlwm xim, kev npaj nto yog ib qho tseem ceeb tshaj plaws. SA2.5 Kev Txhaum Txhaum Cai (Nyob ze-Thiab Hlau Dawb) yog qhov kev lag luam yuav tsum tau ua kom ntseeg tau qhov siab tshaj plaws txheej adhesion.
- Tshem Tawm Mill Scale: Nws tshem tawm cov txheej txheem oxide uas tsim thaum lub sijhawm kub - dov txheej txheem.
- Tsim "Anchor Pattern": Cov txheej txheem tsim ib qho kev ntxhib los mos uas tso cai rau cov xim kom "suav" cov hlau, tiv thaiv tev thiab hauv qab - zaj duab xis corrosion.
3. Khw Primer: Streamlining Site Construction
Lub khw Primer yog ib qho ultra-thin, weldable txheej tam sim ntawd tom qab tua blasting. Nws ua raws li daim thaiv ib ntus thaum lub qhov rais tseem ceeb ntawm kev thauj mus los thiab kev sib dhos.
- Logistics Efficiency: Nws tiv thaiv "flash rust" thaum lub sij hawm shipping, kom cov hlau tuaj txog ntawm qhov chaw ua hauj lwm nyob rau hauv pristine mob.
- Weld-Tus phooj ywg: Siab- cov primers zoo yog tsim los rau welded los ntawm tsis tso pa phem los yog cuam tshuam qhov kev ncaj ncees ntawm vuam.
Environmental Severity & Treatment Selection Guide
Xaiv qhov kev kho mob tsis raug tuaj yeem ua rau kev siv nyiaj tsis zoo lossis kev pheej hmoo ntawm kev tsim kho. Xa mus rau cov matrix hauv qab no rau kev xaiv cov tswv yim:
| Environmental Qeb | Tej yam xwm txheej | Pom zoo S275JR tiav |
| C1 / C2 (tsawg) | Sab hauv tsev warehouses, rhuab tsev | Khw Primer lossis Standard Xim |
| C3 (Medium) | Nroog/Industrial atmospheres, high humidity | Tua Blasting SA2.5 + Ntau- txheej xim |
| C4 / C5 (hnyav) | Cov ntug hiav txwv dej, cov nroj tsuag tshuaj, offshore | Kub-Dip Galvanizing (HDG) |
| Modular Tsev | Ceev- taug qab kev lag luam kev tsim kho | Ua ntej -primed S275JR Channels |
