Cov huab cua tiv thaiv ntawmQ460NH Weathering HlauYuav ua tau zoo heev los ntawm cov kev kho mob nto, txawm tias nws tau txais corrosion tsis kam yog twb zoo dua rau cov pa roj carbon hlau. Hauv qab no yog cov qauv pov thawj thiab lawv cov kev cuam tshuam ua haujlwm:
1. Kev kho patina nrawm nrawm
| Kev kho | Lub tshuab | Hauj tes |
|---|---|---|
| Tannic acid Ntxuav | Cov ntaub ntawv ruaj khov fe-tannate complex | Txo patina stabilization lub sij hawm los ntawm 50-70% |
| Phosphoric acid | Tsim Hlau Phosphate Barier Txheej | Txhim kho qhov pib corrosion tsis kam |
| Ntsev tshuaj tsuag cycling | Aristial ntub / Lub voj voog qhuav | Accelerates ntuj pata tsim |
Qho kawg: Tiav kev tiv thaiv Patina nyob rau hauv3-6 hlis(vs . 12} - 24 hlis ib txwm).
2. Kev tiv thaiv kev tiv thaiv (ib nrab / puv)
Breathable txheej(xws li, acrylic-sixane):
Cia cov pa oxygen sib txawv rau kev txhim kho patina hauv qab.
Txo cov kev tso dej thaum pib los ntawm 90%.
Zinc-nplua nuj:
Siv tsuas yog ntawm Weld aav / txiav sawv rau kev tiv thaiv Cathodic.
Zoo tshaj plaws rau: Ntug dej hiav txwv (C5-M) lossis ib puag ncig muaj kuab paug.
3. Laser Deg Kev Hloov Kho
Laser chaening: Induces compressive kev ntxhov siab rau retard bream pib.
Laser alloying: Adds Cr/Ni to surface layer (increases Cr content to >5%).
Qho kawg: Txuas ntxiv kev pabcuam lub neej los ntawm20–30%nyob rau hauv cov xwm txheej hnyav.
4. Cov ntaub ntawv sib piv
| Qhov xwm txheej nto | Corrosion tus nqi (μm / xyoo) | Kev Pab Lub Neej (C4) |
|---|---|---|
| Tsis tau kho Q460NH | 25–30 | 50-60 xyoo |
| Cov tannic acid-kho | 15–20 | 70-80 xyoo |
| Siloxane-Coated | 5–10 | 100+ xyoo |
5. Cov lus pom zoo tswv yim
Rau Hauv Nroog Nroog (C3): Tannic acid kho qhov txaus.
Nqaum / Muaj (C4-C5): Sib txuas phosphoric acid ntxuav + breathable txheej.
Cov pob qij txha tseem ceeb: Laser chanening + zinc primer.
