Q460NKH cov huab cua tsis kamtuaj yeem thuamHauv cov chaw muaj kuab paugVim yog cov ntses acid (sulfuric / nitric acid) thiab leej faj tebchaw, tab sis nws cov kev ua tau tseem tseem surpasses carbon hlau. Ntawm no yog qhov tawg:
1. Kev cuam tshuam ntawm kev muaj kuab paug
Acid los nag (Ph<4.5):
Slows / nres qhov tiv thaiv Matina tsim los ntawm kev ua tiavCu / Cr-nplua nuj Oxides.
Tej zaum yuav nce cov xeb corrosion los ntawm20–50%vs. nyob deb nroog.
Sulphur dioxide (so₂):
Reacts nrog noo noo los uasulfuric acid, ua rau pitting thiab xoob xeb.
Hauv cov neeg mob hnyav (piv txwv li, ze rau cov nroj tsuag thee), cov nqi corrosion tuaj yeem ncav cuag0.1 mm / xyoo(vs . 0.03 hli / xyoo nyob rau hauv cov huab cua huv).
2. Kev Pab Tswv Yim
Kev tsim ua: Ua kom cov ntaub ntawv tuab rau cov nyiaj rau ntau dua corrosion ploj.
Kho:
Yaug cov chawib ntus kom tshem tawm cov acidic tso nyiaj.
Thov Txheej Txheem(piv txwv li, epoxy primers) nyob rau hauv cov cheeb tsam loj heev.
Lwm Yam Khoom: Rau kev ua qias tuaj (piv txwv li, pH<3.5), consider Stainless-Clad HlaulossisNtau-Qib Huab Cua Cov Hlau(piv txwv li, Astm A588 qib K).
3. Sib piv rau lwm qhov chaw ib puag ncig
| Huab cua | Corrosion tus nqi (MM / Xyoo) | Patina stability |
|---|---|---|
| Nyob deb nroog (huv) | 0.02–0.03 | Zoo tshaj |
| Nroog (Nruab Nrab) | 0.03–0.05 | Zoo |
| Muaj (so₂) | 0.05–0.10 | Ncaj Ncees (yuav tsum tau soj ntsuam) |
| Tubrog Nkoj (Ntsev) | 0.07–0.12 | Tswj kav |
