Titanium Electrode Phaj rau Hydrogen Electrolyzer

Cov hlau oxide-coated titanium electrode tau qhia luv luv. Titanium electrode tau siv ntau hauv kev lag luam electrolytic txij thaum lawv tsim. Lub titanium electrode yog thawj zaug tsim los ntawm H.Beer hauv xyoo 1965.

Coated titanium electrode daim ntaub ntawv: Chlor-alkali kev lag luam, chlorate kev lag luam, hypochlorous acid ntsev kev lag luam, zus tau tej cov perchlorate, electrolytic txheej txheem tsim tooj liab ntawv ci, electrolytic persulfate, electrolytic organic synthesis, electrolytic extraction ntawm hlau, zus tau tej cov electrolytic nyiaj catalyst, electrolytic oxidation txheej txheem Kev siv cov mercury, electrolysis dej, tsim cov tshuaj chlorine dioxide hauv tsev kho mob cov dej khib nyiab, kev lag luam electroplating, dej, thiab khoom noj khoom haus tshuaj tua kab mob, Fais fab nroj tsuag txias circulating dej kho, ib txoj kev electrolytic kom tau acid thiab alkali ionic dej, chromium plating, palladium plating, Kub plating, ruthenium plating steel phaj, electrodialysis desalination ntawm seawater, cov khoom siv daim ntawv thov teb koom nrog kev lag luam chemical, metallurgy, dej kho, kev tiv thaiv ib puag ncig, electroplating, electrolysis organic synthesis, thiab lwm yam electrolytic industries.

Keeb kwm kev loj hlob

  Titanium electrodehnub rov qab ntau tshaj 200 xyoo mus rau 1786. Tus neeg sawv cev tshaj plaws ntawm caustic soda kev lag luam aqueous tov electrolysis kev lag luam tuaj yeem piav qhia txog keeb kwm ntawm cov ntaub ntawv electrode.

Saline electrolysis tau pib hauv chav kuaj, siv platinum electrode, ntuj carbon electrode, ntuj graphite electrode, hlau nplaum hlau oxide electrode, thiab lead dioxide electrode. Cov no yog thawj cov khoom siv electrode kuaj.

Saltwater electrolysis xav kom cov khoom siv anode muaj cov ntsiab lus zoo catalytic kev ua tau zoo rau chlorine nag lossis daus, zoo kav ntev, thiab muaj peev xwm tiv thaiv cov nag lossis daus. Thawj electrode siv nyob rau hauv industrial ntau lawm yog graphite electrode. Cov graphite electrode tuaj yeem ua tau raws li cov kev xav tau saum toj no thaum lub concentration ntawm cov dej ntsev siab. Txawm li cas los xij, nws pom tias graphite anode muaj qhov tsis zoo hauv qab no hauv kev tsim khoom ntev: kev ua haujlwm siab

Yog li ntawd, lub zog noj yog loj; Nrog cov txheej txheem ntawm cov tshuaj tiv thaiv electrochemical, qhov poob ntawm graphite electrode yog qhov loj, thiab cov electrode nyob deb hloov pauv, ua rau tsis ruaj khov electrolytic ntau lawm. Chlorinated reactive nto yog qhov nyuaj los tswj.

Tom qab tib neeg keeb kwm nkag mus rau xyoo 1960, kev lag luam petrochemical tau tsim sai heev, ntau cov nroj tsuag loj ethylene tau tsim nyob rau ntau qhov chaw, thiab cov khoom siv hluavtaws ntawm cov organic chloride tau nce ntau heev. Lub sijhawm no, graphite anode yuav tsum muaj peev xwm ua tau zoo, qhib qhov hauv graphite anode, kev ua haujlwm ntawm graphite anode nws tus kheej tsis zoo heev, nws xav tau cov khoom tshiab los hloov nws. Cov hlau anodes ntxov tshaj plaws yog platinum anodes, tab sis lawv tsis tau siv dav vim lawv cov nqi siab.

Los ntawm 1910 txog 1940, titanium daim txhuam cev tau tsim los ntawm magnesium thiab sodium thermal txo. Thiab ntau lawm. Titanium anode raws li lub substrate qhia titanium tseem hu ua valve hlau, ruaj khov oxide txheej tiv thaiv, yog li ntawd cov anode electrode tsis dhau, yog li nyob rau hauv dej ntsev, electrolysis tej yam kev mob muaj zoo durability thiab stability. titanium hlau tuaj yeem ua tau raws li qhov xav tau thiab tuaj yeem tsim titanium daim hlau, titanium rods, titanium hlau, titanium mesh, titanium raj, porous daim hlau, thiab lwm yam. Siv dav.

Nyob rau xyoo 1960, ntxiv rau kev tsim cov coated electrodes, dav siv hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, hydroelectricity, dej kho, electrometallurgy, electroplating, hlau ntawv ci, thiab ntau lwm yam lag luam.

Qhov zoo

Lub anode ruaj khov heev. Tsawg ua hauj lwm voltage, tsawg zog noj, thiab dc zog noj yuav txo tau los ntawm 10-20 feem pua. Titanium anode muaj lub neej ua haujlwm ntev. Nws overcomes lub dissolution ntawm graphite anode thiab txhuas anode thiab zam cov khoom ntawm electrolyte thiab cathode. High tam sim no ceev, me me overpotential, thiab siab catalytic kev ua ntawm electrodes tuaj yeem ntes cov khoom siv tau zoo. Nws tuaj yeem zam qhov teeb meem luv luv tom qab txhuas anode deformation thiab txhim kho kev ua haujlwm tam sim no. Cov duab yog ib qho yooj yim los ua thiab muaj peev xwm ua tau siab precision. Cov titanium matrix tuaj yeem rov siv dua. Tsawg tshaj li cov yam ntxwv, qhov saum npoo ntawm electrodes thiab electrode npuas yog yooj yim tshem tawm, thiab tuaj yeem txo cov hluav taws xob hluav taws xob ntawm tes.
