Titanium anode (tseem hu ua titanium-based hlau oxide coated anode, DSA, Dimensionally Stable Anode) yog cov khoom siv hluav taws xob ua tau zoo siv dav hauv kev lag luam electrochemistry. Nws muaj kev tiv thaiv corrosion zoo heev, kev ua haujlwm siab catalytic thiab lub neej ntev.

1. Cov yam ntxwv tseem ceeb ntawm titanium anode
- Dimensional stability: Qhov sib txawv ntawm electrode tseem tsis hloov thaum lub sij hawm electrolysis txheej txheem, kom ruaj khov ntawm tes voltage.
- Muaj zog corrosion kuj: Haum rau muaj zog acid, muaj zog alkali thiab Cl⁻-muaj xov xwm, nrog corrosion kuj deb tshaj li ntawm graphite thiab txhuas anodes.
- Tsawg khiav hauj lwm voltage: Tsawg overpotential rau oxygen / chlorine evolution, txuag 10% -20% zog.
- Lub neej ntev: Hauv kev lag luam chlor-alkali, lub neej ntev tuaj yeem ncav cuag 6 xyoo, thaum lub graphite anode tsuas yog 8 lub hlis xwb.
- Kev ceev tam sim no: Txhawb 17A / dm² (graphite anode tsuas yog 8A / dm²), txhim kho kev ua haujlwm ntau lawm.

2. Cov chaw thov tseem ceeb
(1) Chlor-alkali kev lag luam
- Electrolysis ntawm brine los tsim cov tshuaj chlorine thiab caustic soda, titanium anode tuaj yeem txo cov cell voltage thiab txhim kho chlorine purity.
- Hloov graphite anode kom tsis txhob muaj cov kab mob electrolyte.
(2) Kev kho dej khib nyiab
- Electrocatalytic oxidation: Degrade organic teeb meem hauv luam ntawv thiab dyeing, tshuaj, thiab coking khib nyiab, nrog rau COD tshem tawm tus nqi txog li 90%.
- Sodium hypochlorite generator: Electrolyze brine los tsim cov tshuaj tua kab mob, siv rau cov dej phwj hauv tsev kho mob thiab kev kho dej hauv pas dej da dej.
- Radioactive wastewater kho: Electrolytic rov qab ntawm radioactive hlau xws li uranium thiab plutonium.
(3) Electroplating kev lag luam
- Siv rau npib tsib xee plating, chromium plating, kub plating, thiab lwm yam.
- Cov pa oxygen evolution overpotential yog 0.5V qis dua li cov hlau lead anode, uas txuag lub zog ntau heev.
(4) Electrolytic metallurgy
- Tshem tawm cov hlau xws li tooj liab, zinc, thiab npib tsib xee, hloov cov hlau lead anode, thiab tsis txhob muaj cov kab mob cathode.
- Haum rau qhov ceev tam sim no (xws li 8000A / m²) thiab nqaim inter-electrode spacing (5mm) cov xwm txheej.
(5) Tshiab zog thiab hydrogen ntau lawm
- Hydrogen ntau lawm los ntawm electrolysis ntawm dej: Txo cov pa oxygen evolution overpotential thiab txhim kho lub zog efficiency.
- Cov roj teeb muaj zog: siv rau titanium-based phaj tsim.
(6) Lwm yam kev siv
- Kev tiv thaiv Cathodic: tiv thaiv corrosion ntawm marine steel qauv, nrog rau kev pab cuam lub neej ntau tshaj 10 xyoo.
- Electrochemical synthesis: xws li kev npaj cov organic tebchaw thiab tshuaj intermediates.

3. txheej txheem txheej thiab xaiv
- Cov txheej txheem ntau:
- Ruthenium (RuO₂): haum rau chlor-alkali kev lag luam, tiv taus Cl⁻ corrosion.
- Iridium (IrO₂): muaj zog acid tsis kam, haum rau kev kho dej khib nyiab.
- Platinum txheej: siv rau high-purity titanium electrolysis, tiv taus kub (600 ℃).
- Cov qauv qauv: phaj, raj, mesh, hlau, thiab lwm yam, tuaj yeem kho raws li qhov xav tau.

4. Kev tu thiab lub neej txuas ntxiv
- Kev tu tsis tu ncua: yaug nrog dej deionized tom qab kaw kom tsis txhob scale deposition.
- Zam kev puas tsuaj: kev puas tsuaj rau platinum txheej yuav ua rau corrosion sai ntawm titanium substrate.
- Electrolytic activation: thim rov qab kho tam sim no txhua 3000 teev kom tshem tawm cov txheej txheem passivation.

5. Txoj kev loj hlob yav tom ntej
- Composite coatings: xws li platinum-iridium gradient coatings, ntxiv txo cov pa evolution overpotential (lub chaw kuaj tau mus txog 1.25V).
- Kev soj ntsuam ntse: kev sib xyaw sensors saib cov txheej poob hauv lub sijhawm.
- Kev tiv thaiv ib puag ncig thiab kev siv hluav taws xob tshiab: xws li cov roj teeb hauv lub xeev thiab cov khoom siv hydrogen tau zoo.
