1. Nto Passivation (Qhov Tseem Ceeb rau Chrome Hlau)
Cov txheej txheem passivation muaj feem cuam tshuam cov hlau pob hauv 20-30% nitric acid (hnoos) daws teeb meem rau 50-30 feeb. Qhov kev kho mob no tau tshem tawm cov kab hlau pub dawb rau saum npoo thaum txhawb cov kev tiv thaiv cov roj ntsha oxide (cr₂o₃) txheej. Raws li ATM A967 tus qauv, hom qauv no tuaj yeem ntxiv rau corrosion tsis kam txog 300%.
2. Kev tiv thaiv txheej txheem
Ua ntawv thov cov txheej tshwj xeeb tsim kev thaiv lub cev tiv thaiv noo noo thiab corrosive ntsiab:
| Txheej Txheej|Lub tswv yim rau|Thickness|Corrosion tsis kam ua kev ua tau zoo |
| ZINC PHOTPPHATE|Carbon Steel|2-5 μm|Withstands 96 teev ntsev tsuag tshuaj |
| Electroless npib tsib xee|Ob qho tib si hlau qub|10-20 μm|Muab tshaj 500 teev ntawm ntsev tshuaj tsuag tiv thaiv |
| Dacromet ®|High - noo noo ib puag ncig|6-8 μm|Muaj 1000+ cov sijhawm ua paug |
3. Vapor corrosion inhibitors (VCI)
VCI thev naus laus zis muab kev tiv thaiv txuas ntxiv thaum lub sijhawm khaws khoom thiab kev thauj mus los. Los ntawm embedding vci capsules nyob rau hauv ntim cov yeeb yaj kiab lossis ua npuas ncauj, amine thiab carboxylate ions, sib sau ua cov txheej txheem kev tiv thaiv. Thaum cov qauv no tau muab khi kom zoo, tuav txoj kev tiv thaiv 2-5 xyoos raws li ISO 11303 tus qauv.
4. Kev tswj ib puag ncig kev cia
Tswj kev cia siab rau cov xwm txheej tseem ceeb ntau txo cov xeb kev pheej hmoo:
- Ua kom cov av noo noo qis dua 40% txheeb ze cov av noo
{{0 {}} tswj qhov kub ntawm 20 ± 5 degree
-}} Hais meej tias Dew nto nyob qis qis tsawg kawg 5℃hauv qab huab cua sov
-}} Siv Silica Gel Desiccants ntawm tus nqi ntawm 200G rau ib lub cubic meter
{{0- saib cov cai yooj yim nrog cov npav av noo
5. Ua kom tiav cov kev cai
Cov kev coj ua yooj yim kev coj ua tiv thaiv kev corrosion thaum ntxov:
-} Txhua zaus coj hnab looj tes nitrile thaum tuav roj (cov roj av nrawm nrawm tsim)
-}}}} siv huv si, roj -}} coated stainless hlau cov tais rau kev thauj mus los thiab cia
-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Tsis txhob sib cuag ncaj qha ntawm Bare Steel pob thiab Carbon Steel Surfaces
6. Rust -} Tiv Thaiv Cov Roj
Zoo Rust -} Kev Tiv Thaiv Cov Roj Tsim Tsim Kev Tiv Thaiv Kev Tiv Thaiv uas cov txwv dej noo:
-}}}}}} is o vg 32 lim roj muaj 3% xeb inhibitor adcessitives
- tectyl® 506 (rooj sib tham mil {{pr-16173e qib 2 specifications)
Yog li cov txiaj ntsig zoo tshaj plaws, cov khoom noj hauv roj kom sov mus rau 60℃rau 5 feeb thiab pub cov roj ntau dhau los tso tseg.
Los ntawm kev siv cov kev tshawb fawb no -}}} Cov khoom siv thauj khoom hauv Chrome thiab cov neeg siv roj carbon monoxide, txo cov nqi kho vaj tsev thiab ua kom muaj kev txhim kho kev ua tau zoo hauv cov ntawv thov tseem ceeb.
