1. Cov ntawv thov tsim nyog
Pom zoo siv:
Txuas hniav & txoj kev loj(Cov neeg tiv thaiv, girders)
Railway dov Tshuag(Freight Wagons, ntim)
Cov Kws Ua Haujlwm Cladding(Facades, duab puab)
Tshuaj Tiv Thaiv Cov Neeg & Khoom Sab Nraud
Zam:
Constantry sillwater / marine kis (sivMarine-qib steelhloov).
Acidic / Alkaline ib puag ncig.
Tsis zoo cua noo lossis dej-ntaiv tsim qauv.
2. Fabrication & vuam
Tej & Drilling
Kev sivntshav, laser, lossis cov neeg siv tshuab txiav(Zam kev ua kom sov ntau dhau los tiv thaiv kev nruj me ntsis).
Laum nrogCarbide-Tipped Bits(Alloy cov ntsiab lus nce hardness vs. carbon hlau).
Vuam
Cov Hluav Taws Xob:Kev sivTsawg-Hydrogen (E7015 / E7016)rau cov txiaj ntsig zoo tshaj plaws.
Preheating:Yuav tsum yog thickness>25mmlossis huab cua temp <5 degree(100-150 degree).
Kev Kho Mob Tom Qab Weld:Tshem tawm slag kom tiv thaiv corrosion kev pib.
3. Corrosion Tswjhwm
Txheej txheej ntuj huab cua
Pub6-24 lub hlisrau ruaj ntseg pata tsim.
Qhov pibXab xebtuaj yeem stain qhov chaw; tsim kev tso tshuaj tiv thaiv kom tsis txhob muaj kev sib cais.
Tshem tawm kom nrawm dua (xaiv tau)
Ua ntaub ntawvdej tshuaj tsuag + Kom qhuav voj voogkom ceev rau kev txhim kho patina.
Kev sivHuab Cua Ntsis(Xws li, tooj liab sulfate daws).
Cov Khaub Ncaws Tiv Thaiv (rau qhov chaw hnyav)
Ntshiab Fuab(piv txwv li, roj linseed) los tswj cov dej ntws thaum ntxov.
Painting:Yuav tsum tau yog siv hauv ntug hiav txwv / muaj ib thaj chaw muaj kev lag luam epox (siv epoxy primers).
4. Tsim Kev Ua Zoo Tshaj
Zam kev ntxaij ntub dej: Siv cov chaw seem, tawm hauv qhov dej ntws tawm.
Tsawg kawg kev sib cuag nrog cov sib luag(piv txwv li, txhuas) los tiv thaiv cov corrosion corrosion.
Kev muab qhib: Xyuas kom muaj cua kom qhuav cov chaw sai.
5. Txij Nkawm
Tshuaj xyuas ib xyoos ib zaugRau kev tsis xeb (flaky los yog powdery xeb qhia tias tsis ua tiav).
Tshem tawm cov khib nyiab / Avtso cai txawm tias patina tsim.
Kho cov khawbLos ntawm kev cia ntuj pata redenerate (lossis kov nrog lub nrawm nrawm).
