Yog vim li cas thiab cov yam ntxwv ntawm titanium anode nyiam los ntawm kev ua lag luam

Lub npe tag nrho ntawm titanium anode yog titanium puag hlau oxide coated titanium anode, tseem hu ua DSA anode (Dimensionally Shape Stable Anode). Nws siv titanium ua cov khoom siv hauv paus thiab muaj cov txheej txheem hlau zoo nkauj ntawm titanium phaj. Titanium anode, titanium coated anode phaj yog ua los ntawm ruthenium, iridium, tantalum thiab lwm yam precious hlau ntsev coated ntawm titanium substrate los ntawm kub sintering, uas yog dav siv nyob rau hauv electroplating (siab tooj liab plating thiab electroplating nyob rau hauv sib sib zog nqus qhov PCB kev lag luam), electrolytic synthesis. , hydrometallurgy, aluminium foil, cathodic tiv thaiv, kev kho dej khib nyiab, tshuaj tua kab mob thiab tshuaj tua kab mob, kev tsim kho thiab rov ua dua tshiab ntawm tooj liab etching tov, thiab titanium anode tau zoo heev hauv kev npaj thiab daim ntawv thov.

Titanium anode raws li titanium puag hlau oxide coated anode, dua li cov khoom siv hluav taws xob dav dav kom muaj cov khoom catalytic zoo, kev hloov me me, kev tiv thaiv corrosion, txhua yam muaj zog thiab kev ua tau zoo, nrov hauv ntau qhov chaw. Thiab tsim nws cov lag luam kub heev, tab sis kuj ua tsaug rau cov laj thawj hauv qab no:

Titanium anode ntev kev pab cuam lub neej, chlorine thiab alkali corrosion nyob rau hauv cov txheej txheem ntawm hlau anode diaphragm nyob rau hauv chlor-alkali industrial ntau lawm. Raws li www.lh-ti.com介绍, piv nrog graphite anode tsuas yog 8 lub hlis ntawm kev siv, titanium anode lub neej expectancy yog ntau tshaj 6 xyoo. Cov qauv siv hluav taws xob tuaj yeem kov yeej qhov teeb meem tawg ntawm graphite anode thiab txhuas anode, tsis txhob muaj kuab paug ntawm cov khoom siv electrolyte thiab cathode, thiab txhim kho purity ntawm cov khoom hlau. Vim yog siv cov hlau anodes, chlorate electrolyzer tuaj yeem ua haujlwm ntawm qhov kub thiab txias tam sim no. Kev siv cov hlau anode tuaj yeem txhim kho cov qauv ntawm electrolyzer, txo kev siv hluav taws xob, thiab ua kom cov tshuaj tiv thaiv ntawm hypochlorite acid hauv hypochlorite, yog li txhim kho kev tsim khoom.

Thib ob, txhim kho qhov ceev tam sim no ntawm diaphragm chlor-alkali ntau lawm txheej txheem, graphite anode tam sim no ntom rau 8A / dm2 titanium anode tuaj yeem nce ntau zaus, xws li 17A / dm2, hauv khw electrolysis, electrolysis tso tsheb hlau luam nyob rau hauv tib lub sijhawm, cov zis tuaj yeem nce ntxiv los ntawm 1 zaug, txhawm rau txhim kho lub peev xwm ntawm ib lub tank, txhim kho kev ua haujlwm zoo. Ib tug quab yuam titanium cov neeg ua haujlwm hauv kev lag luam tau hais tias kev siv titanium anode yog qhov tsim nyog ntau dua nyob rau hauv high tam sim no ceev electrolysis. Tsis tas li ntawd, titanium anode loj yog ruaj khov, thiab qhov kev ncua deb ntawm electrodes tsis hloov thaum electrolysis.

Qhov thib peb, qhov ua haujlwm voltage tsawg, yog li kev siv hluav taws xob tsawg, uas tuaj yeem txuag hluav taws xob, thiab kev siv hluav taws xob tuaj yeem raug txo los ntawm 10% mus rau 20%. Lub ntsiab yog vim li cas rau qhov tsawg ua hauj lwm voltage ntawm titanium anode yog: 1) lub overpotential ntawm active coated titanium anode rau chlorine thiab oxygen yog tsawg. Electrolysis ntau lawm ntawm chlor-alkali brine, titanium anode tshaj-muaj peev xwm rau chlorine yog tsawg, 1A / cm2 yog 140mV qis dua graphite anode; 2) Nws tuaj yeem txo qhov "cov nyhuv npuas tiv thaiv", qhov anode nto hlau npuas tsim yog me me, thiab cov paug tawm sai, yog li cov qib ntawm kev nthuav dav ntawm cov electrodes yog tsawg, thiab cov inter-polarization ohmic voltage poob yog li 700mV. . txoj kab uas hla ntawm npuas yog li 3 hli; 3) nws tuaj yeem txo qhov ua haujlwm voltage ntawm anode, uas yog li ntawm 10-20%. 3 hli; 3) txo qhov tsis kam ntawm cov qauv anode; 4) txo qhov kev ncua deb ntawm electrodes.

Lub tswv yim tsim thiab kev ua haujlwm tuaj yeem txhim kho thiab kev siv hluav taws xob tuaj yeem txo tau los ntawm kev siv DSA, mercury thiab diaphragm ntsev da dej. Tsawg overpotential yam ntxwv ntawm DSA, electrode nto thiab electrode npuas yog yooj yim kom tshem tawm. Nws tau tshaj tawm tias nyob rau xyoo 1960, lub ntiaj teb ntsev electrolysis kev lag luam siv txog 150 billion degrees ntawm hluav taws xob hauv ib xyoos, thiab kev siv cov hlau anodes tuaj yeem txuag tau txog 300 lab degrees ntawm lub zog ib xyoos. Nyob rau tib lub sijhawm, titanium anode yog lub teeb yuag, uas tuaj yeem txo kev siv zog.
