Tom qab xyoo ntawm lub Hoobkas tsim thiab kev tshawb fawb, nws tau pom tias piv nrog cov tsoos graphite electrodes thiab txhuas-raws li kev sib xyaw, kub electrodes, titanium electrodes muaj cov hauv qab no zoo:
Qhov loj ntawm lub anode yog ruaj khov, thiab qhov kev ncua deb ntawm cov electrodes tsis hloov thaum lub sij hawm electrolysis txheej txheem, uas ua kom ntseeg tau tias lub electrolysis ua hauj lwm nyob rau hauv cov kev mob ntawm ruaj khov cell voltage.
Lub zog ua haujlwm tsawg, yog li kev siv hluav taws xob tsawg, uas tuaj yeem txuag hluav taws xob, thiab DC lub zog siv tau tuaj yeem txo los ntawm 10% ~ 20%. Cov laj thawj tseem ceeb ntawm kev ua haujlwm tsis tshua muaj hluav taws xob ntawm titanium anode yog: 1) Lub zog tshaj ntawm cov active-coated titanium anode rau ob qho tib si chlorine thiab oxygen kuj tsawg. Thaum tsim cov chlor-alkali los ntawm cov dej ntsev electrolysis, lub overpotential ntawm titanium anode rau chlorine yog tsawg, uas yog qis dua li ntawm graphite anode ntawm 1A / cm. 140 mV; 2) Nws tuaj yeem txo qhov "npuas thaiv cov nyhuv". Cov npuas tsim nyob rau saum npoo ntawm cov hlau anode yog me me thiab tawg sai sai. Nyob rau hauv txoj kev no, lub aeration ntawm cov electrodes yog heev txo, thiab lub ohmic nco ntawm ob tug ncej yog ho txo. Piv txwv li, ntawm 10kA / m2, cov hlau anode Lub inter-ohm poob qis dua 100mV thiab cov npuas taub yog 1 hli, thaum lub graphite anode ohm poob yog li 700mV thiab cov npuas taub yog li 3 hli; 3) Kev ua haujlwm ntawm cov qauv anode raug txo; 4) Lub inter-electrode nrug yog luv.
Titanium anodes muaj lub neej ua haujlwm ntev. Hauv kev lag luam chlorine gas ntau lawm siv txoj kev diaphragm, hlau anodes yog resistant rau corrosion los ntawm chlorine thiab alkali, nrog ib tug anode lifespan tshaj 6 xyoo, thaum graphite anodes tsuas kav rau 8 lub hlis.
Nws tuaj yeem kov yeej qhov teeb meem ntawm kev sib cais ntawm graphite anode thiab txhuas anode, tsis txhob kis cov khoom siv electrolyte thiab cathode, thiab yog li txhim kho cov purity ntawm cov khoom hlau.
Platinum Coated Titanium Phaj Electrode Rau Hydrogen-Rich Dej Lub raj mis
Muaj peev xwm nce qhov ceev tam sim no. Hauv kev tsim cov chlor alkali siv txoj kev diaphragm, kev ua haujlwm tam sim no ntawm graphite anode yog 8A / dm2, thiab titanium anode tuaj yeem nce exponentially mus rau 17A / dm2. Raws li cov xwm txheej zoo ib yam li cov nroj tsuag electrolytic thiab electrolytic cell, cov zis tuaj yeem raug muab faib ua ob npaug, txhim kho lub peev xwm ntawm ib lub xov tooj ntawm tes thiab txhim kho kev ua haujlwm zoo. Thaum electrolyzing ntawm kev ua haujlwm siab tam sim no, siv titanium anodes yog qhov tsim nyog dua.
Hauv kev tsim cov chlor alkali, kev siv cov titanium anodes ua rau cov khoom lag luam zoo, siab purity ntawm cov roj chlorine, tsis muaj CO2, siab alkali concentration, thiab tuaj yeem txuag tau cua sov chav thiab lub zog noj.
Titanium Electrodes rau haus dej tua kab mob
Muaj zog corrosion kuj, tuaj yeem ua haujlwm nyob rau hauv ntau yam corrosive thiab tshwj xeeb electrolytic media.
Titanium Electrodes Rau Pas Dej Dej Disinfection
Nws tuaj yeem zam qhov teeb meem luv luv tom qab deformation ntawm cov hlau lead anode, yog li kev txhim kho tam sim no efficiency.
Qhov tshwm sim ntawm cov hlau anodes tau ua rau qhov tseeb ion membrane electrolysis thev naus laus zis uas tau tshwm sim hauv kev lag luam chlor alkali los tsim thiab industrialized.
Vim yog siv cov hlau anodes, qhov kub thiab txias ua haujlwm siab tam sim no hauv chlorate electrolysis hlwb tau ua tau. Kev siv cov hlau anodes txhim kho cov qauv ntawm cov electrolytic cell, txo kev siv zog, ua kom cov tshuaj tiv thaiv hypochlorite rau chlorate, thiab yog li txhim kho kev ua haujlwm ntau lawm.
Titanium Anode Rau Nruam Nruam DC Copper Plating
Lub tswv yim tsim thiab kev ua haujlwm ntawm cov ntsev electrolysis siv DSA, mercury method, thiab membrane method tau raug txhim kho, ua rau txo qis zog noj. Cov yam ntxwv tsis tshua muaj peev xwm ntawm DSA, nrog rau kev tshem tawm yooj yim ntawm npuas ntawm qhov chaw ntawm electrodes thiab electrodes, yog qhov tseem ceeb rau kev txo qis hauv cov hlau anode electrolysis hlwb.
Vim nws muaj ntau yam zoo, kev txhim kho ntawm titanium anodes tau coj cov txiaj ntsig zoo rau kev lag luam chlor alkali, thiab vim li ntawd, lawv tau nce sai thiab siv thoob ntiaj teb. Lub peev xwm ntau lawm ntawm chlor alkali yog kwv yees li 41 lab tons / xyoo thoob ntiaj teb, siv titanium anodes tsis tsawg dua 70%. Titanium anode yog hailed raws li ib tug loj tech kiv puag ncig nyob rau hauv lub chlor alkali kev lag luam. Tom qab ntawd, titanium anodes tau nthuav dav thiab siv hauv ntau lub lag luam electrolysis.
