Txoj kab uas hla 300mm Platinum-coated Titanium Anode phaj

Ib txoj kab uas hla 300 hli platinum-coated titanium anode phaj yog hu ua titanium-based hlau oxide-coated titanium anode (MMO). Kuj hu ua DSA anode (dimensionally ruaj khov anode). Nws siv titanium ua lub substrate thiab txhuam cov hlau zoo ntawm cov titanium substrate kom nws muaj kev ua haujlwm zoo electrocatalytic thiab hluav taws xob conductivity. Piv nrog pristine graphite anodes thiab txhuas anodes, titanium electrodes muaj qhov zoo hauv qab no:

Platinium-coated titanium electrode

nthuav dav ntawm titanium electrode

1. Qhov loj ntawm electrode yog qhov ruaj khov, thiab qhov kev ncua deb ntawm cov electrodes yuav tsis hloov thaum lub sij hawm electrolysis txheej txheem, kom ntseeg tau tias lub electrolysis ua hauj lwm yog nqa tawm nyob rau hauv tus mob uas lub cell voltage yog ruaj khov;

2. Kev ua haujlwm siab catalytic thiab qis ua haujlwm voltage;

3. Lub zog ua haujlwm qis, yog li kev siv hluav taws xob tsawg, thiab DC lub zog siv tau tuaj yeem txo tau 10 feem pua ​​---20 feem pua;

4. Lub neej ua haujlwm ntawm titanium anode yog ntev. Cov hlau anode hauv chlorine gas ntau lawm los ntawm txoj kev diaphragm yog tiv taus corrosion los ntawm chlorine thiab alkali. Lub neej ntawm lub anode tau mus txog ntau tshaj 5 ~ 7 lub hlis, thaum lub graphite anode tsuas yog 8 lub hlis;

5. Nws tuaj yeem kov yeej qhov teeb meem ntawm kev sib cais ntawm graphite anode thiab txhuas anode, thiab tsis txhob muaj kuab paug ntawm cov khoom siv electrolyte thiab cathode, yog li txhim kho qhov purity ntawm cov khoom hlau zoo heev.

6. Nws tuaj yeem txhim kho qhov ceev tam sim no thiab ua kom cov electrolysis efficiency;

7. Cov oxides ntawm noble hlau thiab cov rau tes muaj oxidation tsis kam, yog li titanium electrodes muaj zog corrosion kuj;

8. Nws tuaj yeem zam qhov teeb meem luv luv tom qab deformation ntawm cov hlau lead anode, txhawm rau txhim kho qhov ua tau zoo ntawm qhov tam sim no;

9. Titanium electrode yog lub teeb hauv qhov hnyav, uas tuaj yeem txo kev siv zog piv nrog graphite anode thiab txhuas anode;

10. Cov duab thiab tsim khoom ntawm titanium matrix yog qhov yooj yim, thiab siab precision tuaj yeem ua tiav:

11. Nyob rau hauv qhov chaw tsis muaj kev puas tsuaj, lub substrate tuaj yeem sim rov ua dua

Titanium anode kev faib tawm:

1. Raws li cov roj evolution ntawm cov anode hauv cov tshuaj tiv thaiv electrochemical, cov tshuaj chlorine evolution anode hu ua chlorine evolution anode, xws li cov ntsia hlau-coated titanium electrode: cov pa oxygen evolution anode hu ua oxygen evolution anode, xws li cov coated. titanium electrode thiab platinum titanium mesh. / phaj. Chlorine-evolution anode (tus ntsia thawv-coated titanium electrode): Cov ntsiab lus chloride ion nyob rau hauv cov electrolyte yog siab, feem ntau nyob rau hauv ib puag ncig ntawm hydrochloric acid, electrolysis ntawm seawater, thiab electrolysis ntawm ntsev dej. Cov khoom sib xws ntawm peb lub tuam txhab yog ntsia thawv iridium titanium anode thiab ntsia thawv iridium tin titanium anode.

2. Oxygen evolution anode (nyob ntawm cov coated titanium electrode): Cov electrolyte feem ntau yog ib puag ncig sulfuric acid. Cov khoom sib xws ntawm peb lub tuam txhab yog tantalum anode, tantalum-tin-titanium anode, thiab high-yield anode titanium anode.

3. Platinum-coated anode: titanium yog cov khoom siv hauv paus. Qhov saum npoo yog coated nrog platinum, lub thickness ntawm txheej yog feem ntau 0.5-5um, thiab lub mesh loj ntawm platinum titanium mesh feem ntau yog 12.5x4.5mm los yog 6x3.5mm.

Qhov tseeb siv platinum-coated titanium electrodes

1. Ua ntej siv platinum-coated titanium electrodes, nws yog ib qho tsim nyog yuav tsum tau tshem tawm (yuav tsum tau kuaj) lub neej ntawm "chloride" ions thiab "phosphate" ions hauv cov tshuaj plating, thiab nws muaj kev nyab xeeb kom paub meej tias tsis muaj tshuaj lom neeg muaj pes tsawg leeg. corrodes platinum-coated titanium electrodes. Siv platinum-coated titanium electrodes, txwv tsis pub, hauv qab substrate ntawm platinum-coated titanium electrodes yuav raug corroded hnyav, platinum txheej yuav poob, thiab lub neej kev pab cuam yuav luv luv.

2. Tsim nyog xaiv cov txheej txheem zoo tshaj plaws: tam sim no qhov ntom ntom ntawm platinum-coated titanium electrode yog qhov zoo dua hauv qab 50A / dm2, thiab lub tank siab qis dua 10V, txwv tsis pub lub neej kev pabcuam yuav raug cuam tshuam, thiab cov anode yuav raug corroded hnyav thiab yaj, thiab cov txheej yuav poob, sim xaiv Cov txheej txheem ntawm cov tshuaj tiv thaiv anodizing yam tsis muaj kev tsim cov khoom oxides zam oxide thickening thiab passivation cuam tshuam cov conductivity ntawm platinum-coated titanium electrodes. Yog vim li cas rau anode tawg yog txiav txim los ntawm cov yam ntxwv ntawm cov khoom titanium nws tus kheej. Thaum lub xov tooj ntawm tes siab tshaj 10V, titanium nto nyob rau hauv kev sib cuag nrog lub platinum txheej pib yaj me ntsis, thiab nws lov tag nrho ntawm 12V. Tom qab kev puas tsuaj, lub xov tooj ntawm tes peb pom tsis tuaj yeem tshwm sim ntxiv lawm. 12V tsuas pom tau txog 11V. Lub sijhawm no, qhov tam sim no tsis tuaj yeem muab ntxiv, thiab cov anode puas lawm. Yog li ntawd, lub siab ntawm lub tank rau kev nyab xeeb siv platinum-coated titanium electrodes yog teem rau hauv qab 10V.

3. Nyob rau hauv txoj cai, qhov chaw ntawm lub cathode yuav tsum yog me dua qhov zoo anode cheeb tsam (uas yog, anode cheeb tsam nyob rau hauv cov kua nto). Nws yuav tsum tsis txhob siv thaum thaj tsam anode me dua qhov chaw cathode, txwv tsis pub, lub anode yuav yooj yim tawg thiab siv tsis tau ib txwm.

4. Thaum lub impedance ntawm lub plating tank nce, lub tank siab kuj yuav nce. Thaum lub tank voltage siab tshaj 10V, qhov tam sim no yuav tsum tsis txhob nce ntxiv, tab sis tam sim no yuav tsum tau hloov kho kom tsim nyog, xws li: tam sim no raug txo los ntawm 10 feem pua, thiab lub sij hawm plating yog ncua los ntawm 10 feem pua.
