Lub corrosion tsis kam ntawmQ550NHERING STEELthiabGalvanized steelNyob ntawm ib puag ncig thiab ntev - xyoo xav tau kev pab. Ntawm no yog qhov sib piv ncaj qha:
1. Q55050nhireing hlau
Lub tshuab: Ua AKev tiv thaiv xeb patina(ntom, adherent oxide txheej) dhau sijhawm.
Zoo tshaj plaws rau:
Atmospheric piav qhia(Hauv nroog, kev lag luam, nyob deb nroog) nrog cyclic ntub dej qhuav / qhuav tej yam kev mob.
Unpainted qauvQhov twg lub zog ruaj khov yog tau.
Qhov Zoo:
Tsis muaj kev txij nkawm tom qab Patina Ruaj Khetilization (~ 2-5 xyoos).
Superior ntev - sij hawm tiv taus nyob rau hauvkuab paug / so - nplua nujib puag ncig.
Kev txwv:
Tsis haum rauRaws li noo noo, submersion, lossis siab - ntsev (ntug dej hiav txwv txaws zones).
Thaum pib ua dej ntws xeb tuaj yeem siv cov ntaub ntawv puag ncig.
2. Galvanized steel (zinc - coated)
Lub tshuab: Zinc fij rau kev tiv thaiv kev tiv thaiv cov hauv paus hlau.
Zoo tshaj plaws rau:
High - av noo / Nqaumthaj chaw (ntsev tshuaj txau).
Cov ntawv thov yuav tsum tau ua kom huv, hlau(piv txwv li, txhim khu hluav taws xob, cov fasteners).
Qhov Zoo:
Tiv thaiv tam sim ntawd, txawm tias nyob hauvntub / chloride - nplua nujib puag ncig.
Kev kwv yees lub neej (piv txwv li, 50-100 μm zinc kawg ~ 20-50 xyoo hauv huab cua dav heev).
Kev txwv:
Zincenes sai dua hauvAcidic / Muajhuab cua (ph<6 or >12).
Yuav tsum tauRov - galvanizing lossis pleev ximib zaug zinc yog tsis txaus ntseeg.

|---|---|---|
| Kev Tsim Kho Corrosion | Tus kheej - tiv thaiv patina | Kev fij Zinc Txheej |
| Qhov zoo tagnrho ib puag ncig | Qhuav / ntub kev caij tsheb kauj vab (nroog loj / Industrial) | Lub teb chaws noo / Nqaum |
| Kho | Tsis muaj tom qab patina daim ntawv | Re - txheej thaum kawg xav tau |
| Lub neej | {{0 {}} xyoo (hauv huab cua uas haum) | 20-50 xyoo (nyob ntawm Zinc Thickness) |
| Kev ua kom zoo nkauj | Rusty tsos | Nws yog xim hlau / nyiaj tas |
Thaum twg xaiv qhov twg?
Q550NH: Cov choj, Architectural façades, lossis cov qauv hauvMuaj Cov Sawv Cev / Hloov Khoqhov twg xeb yog tau txais.
Galvanized steel: Fencing, vov tsev, lossisNqaum / siab - av nooCov ntawv thov yuav tsum tau saib huv.
Hybrid Kev Xaiv
Rau cov chaw hnyav (piv txwv li, cov choj Nqis), sib txuas:
Galvanized Base Txheej(rau kev tiv thaiv thawj zaug).
Q550nh sab nraud panels(rau cov durability thiab zoo nkauj).
