1. Kev tiv thaiv corrosion hauv cov theem thaum ntxov
Thawj zaug xeb tsim:
SmA490aw tsim cov kev tiv thaiv patina (xeb txheej) dhau sijhawm, tab sisThaum ntxov-theem xeb tuaj yeem stain ncig qhov chaw(xws li, qhob, txoj kev taug kev).
Lus teb: Sivib ntus txheejlossis-xeb-inhibing khokom txog thaum PATINA ruaj khov (6 hlis-2 xyoos).
Chloride kis:
Zam tsis txhob siv rau hauv ntug hiav txwv (qab ntsev) lossis de-icing ntsev ib puag ncigYog tsis muaj kev tiv thaiv ntxiv (piv txwv li, pleev xim) yog thov.
2. Tsim & Fabrication Teeb Meem
(1) Dej Tis & Cov Kua Muag
Hnab ris ntawm cov dej tsis huvleeb corrosion.
Lus teb: TsimSloped nthwv dejthiabKov dej qhovkom tiv thaiv kev tso dej.
Zam kev ua txhaumNyob rau hauv bolted / riveted pob qij txha (siv cov foob yog tsim nyog).
(2) galvanic corrosion kev pheej hmoo
Thaum txuas nrog kev sib txuas(piv txwv li, txhuas, hlau stainless), sma490aw tuaj yeem nrawm dua.
Lus teb: SivCov ntaub ntawv insulating(roj hmab, yas) lossisCov Anodes fij.
(3) Qaug zog & kev ntxhov siab kev pom zoo
Nepch-rhiabVim muaj zog siab-tsis txhob ntse fab hauv kev tsim.
Lus teb: Sivpuag ncig hloov chawthiabCaj weld profiles.
3. VUAM & POST-WELD Care
Weld lwj (haz corrosion):
TusROJ KUB-EURER ZEAM (HORK)Tej zaum corrode sai dua li lub hauv paus hlau.
Lus teb: SivTsawg-hydrogenen vuam, cov tub lim kom raug hlau (piv txwv li, E7018), thiabTom qab Weld Tu.
Kev tswj distortion:
Kev tawm tshiab kub tuaj yeem ua rau warping-sivtus hlau vuamthiabpalanced vuam ua ntu zus.
4. Kev Txij Nkawm & Tshuaj Xyuas
(1) Kev Soj Ntsuam
Kos rau:
Tsis muaj xeb(qhia tias tsis zoo PATINE tsim).
Pitting lossis flaking xeb(Kos npe ntawm kev xeb nruj).
Tawg(kev qaug zog lossis kev cuam tshuam ntsig txog).
(2) Tu & Kho
Tsis txhob tshem tawm ruaj ntseg patina(Nws yog tiv thaiv).
Rau kev mob loj: Lub teeb sandblasting +Huab Cua-Resyuam Primer(Yog tias xav tau kev ua haujlwm).
