Galvanized hlau
Galvanized steel phaj
Nrhiav rau corrosion-tiv taus, siab- lub zog steel rau kev tsim kho ntug dej hiav txwv? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas ncaj qha tshwj xeeb hauv cov qauv hlau, GNEE Steel cov khoom siv EN 10346-ua rawsS350GD Z275 galvanized steel daim hlau-qhov kev xaiv saum toj kawg nkaus rau cov tsev nyob ntug hiav txwv. Hauv phau ntawv qhia no, peb yuav piav qhia vim li cas nws cov txheej txheem tshwj xeeb thiab lub zog ua rau nws tsis tuaj yeem nyob hauv ntsev- nplua nuj nyob hauv ntug dej hiav txwv.
Galvanized steel yog hlau nrog zinc txheej uas thaiv corrosion, dav siv hauv kev tsim kho, tsheb, thiab kev lag luam marine. Cov qib sib xws xws li S280GD, S320GD, thiab S350GD sib txawv ntawm lub zog, thaum "Z275" qhia txog zinc txheej hnyav ntawm 275g / m² (tag nrho ob sab)- tseem ceeb rau cov ntug dej hiav txwv durability.
S350GD Z275 sib xyaw ua ke cov txiaj ntsig siab zog (Ntau dua lossis sib npaug ntawm 350MPa) nrog cov zinc txheej hnyav, daws ob qhov kev tsim kho ntawm ntug hiav txwv loj: dej ntsev corrosion thiab cov khoom siv thauj khoom -cov kabmob xav tau.

Dab tsi ua rau S350GD Z275 tiv thaiv ntug hiav txwv ntsev Corrosion?
Cov ntug dej hiav txwv ib puag ncig hnyav heev - ntsev tsuag, cov av noo siab, thiab cov dej hiav txwv txaws ua kom cov hlau xeb. S350GD Z275 tawm tsam qhov no nrog peb qhov tseem ceeb tiv thaiv -corrosion zoo:
1. Hnyav Z275 Zinc Txheej
Cov txheej "Z275" txhais tau tias 275g / m² tag nrho zinc (≈137.5g / m² ib sab) - 2x tuab dua li txheej txheem Z140. Qhov no zinc ntxiv txuas ntxiv lub sijhawm "kev tiv thaiv kev txi", qhov twg zinc corrodes ua ntej los thaiv cov hlau.
2. Dual Protection Mechanism
- Barrier tiv thaiv: The dense zinc layer physically blocks saltwater, oxygen, and moisture from reaching the steel base.
- Cathodic tiv thaiv: Txawm tias cov txheej txheej khawb, zinc (ntau reactive dua hlau) ua raws li anode, tiv thaiv steel xeb nyob rau hauv qhov chaw puas.
3. Corrosion Test Results
GNEE Steel's S350GD Z275 tau dhau qhov kev sim ntawm ntug dej hiav txwv nruj:
| Hom kev xeem | Cov xwm txheej | Kev tshwm sim |
|---|---|---|
| Neutral Salt Spray Test | 5% NaCl tov, 35 degree, nruam | Tsis muaj xeb liab rau ntau dua lossis sib npaug rau 1,200 teev |
| Cyclic Corrosion Test | Cov tshuaj tsuag ntsev → ziab → vaum voj voog | Hla 200 lub voj voog (≈10 xyoo siv ntug hiav txwv) |
| Field Test (Teb chaws ntug dej hiav txwv) | 2 xyoo raug nyob rau hauv Shenzhen, Suav teb | Txheej poob Tsawg dua lossis sib npaug li 30g / m²; tsis muaj xeb |
S350GD Z275 lub zog ua tau raws li kev tsim kho ntug hiav txwv
Cov tsev nyob ntug dej hiav txwv ntsib cov khoom thauj ntau ntxiv- cua daj cua dub, cua daj cua dub surges, thiab tidal rog. S350GD Z275 cov khoom siv kho tshuab ua kom muaj kev nyab xeeb ntawm cov qauv:
