1. Dab tsi yog cov kev tiv thaiv corrosion zoo tshaj plaws?
Cathodic Kev Tiv Thaiv Cov TshuabSiv Anodes tseem ceeb los yog ua kom zoo nkauj tam sim no
Tshuaj Lom Neeg Inhibitorssuav nrog cov pa oxygen scavengers thiab phua kho
Cov Khaub Ncaws Tiv Thaivxws li thermal tsuag aluminium lossis ceramic linings
Tsim nyog xaivtxuam cov alloys rau kev pabcuam
Kev Ua Haujlwm Tswj Haujlwmtswj cov dej ua kom zoo tshaj plaws
2. Cov hom txheej sib txawv sib txawv rau corrosion tsis kam?
Metallic Txheej txheem (HVOF, ARC tshuaj txau): Zoo heev rau Kev Kub-Kub Oxidation
Tej hub txheej txheem txheej txheem: Superior rau abrasive / Corrosive ib puag ncig
Organic Txheej: Txwv tsawg tsawg qhov kub thiab txias
Cladding: Muab cov tshuaj corrosion loj rau cov chaw tseem ceeb
Diffusion Txheej ci: Ua Metallurgical Bond nrog lub hauv paus hlau
3. Dab tsi dej cov tshuaj chemistry feem ntau cuam tshuam corrosion?
| Chaw ua uas tsis tau haus | Phiaj Ntau | Kev ntsuas txuj ci |
|---|---|---|
| pH | 9.0-10.5 (Cov Hlau Hlau) | Online / Offline Meters |
| Pa | <7 ppb | Polarographic Sensor |
| Kev coj ua | <100 μS/cm | Kev Saib Xyuas Online |
| Tus kab chlorides | <0.1 ppm | Kuaj |
| Sillica | <0.02 ppm | Spectrophotometry |
4. Dab tsi yog cov kev tswj hwm kev kho mob ntau dua li cas?
Corrosion daim coupon: Cov ntsuas ntsuas phaus
Ert probes: Electrical tsis kam hloov
LPR Probes: Cov ntaub ntawv tiv thaiv corrosion
Ultrasonic Thickness Xyuas: Phab ntsa khiav dim
Hydrogen Preves: Ntes Permeration los ntawm Corrosion
5. Yuav ua li cas xaiv cov ntaub ntawv rau cov chaw ua kom ib puag ncig?
Cov Hlau Hlau: Econical rau tsis-txhoj puab heev
Tsawg Alloy Steel: Zoo oxidation tsis kam (1-3% cr)
Stainless hlau: Rau Chlorides / Condensing cov xwm txheej
Nickel alloys: Heev Corrosion Kuj
Tsis yog xim hlau: Cov ntawv thov tshwj xeeb (iav-kab, PTFE)
