Kev xaiv cov khoom siv anode zoo tshaj plaws rau electrolysis yuav tsum muaj kev xav txog kev ua haujlwm ntawm electrochemical, corrosion resistance, nqi, thiab cov ntawv thov tshwj xeeb scenarios. Cov hauv qab no yog cov yam ntxwv tsom xam thiab cov lus pom zoo rau cov ntaub ntawv tseem ceeb:
I. Kev sib piv ntawm Mainstream Anode Khoom yam ntxwv
1. Titanium-raws li Coated Anodes
Titanium-raws li anodes coated nrog hlau oxides (xws li ruthenium- iridium coatings) muaj kev ua tau zoo tag nrho, muaj kev ua haujlwm siab electrocatalytic, tsis tshua muaj peev xwm, lub neej ntev, thiab muaj zog corrosion kuj, ua rau lawv tshwj xeeb tshaj yog haum rau kev thov xws li chlor-alkali kev lag luam. Lawv qhov tsis zoo yog tus nqi pib dua, tab sis lawv cov txiaj ntsig kev lag luam ntev - yog qhov tseem ceeb.
2. Graphite electrodes
Graphite electrodes muaj cov khoom siv hluav taws xob zoo thiab tus nqi qis, ua rau lawv tsim nyog rau chav kuaj lossis me me - nplai electrolysis (xws li dej sib cais). Txawm li cas los xij, nws muaj zog txhua yam tsis tshua muaj zog thiab ua rau oxidation thiab hnav, yuav tsum tau hloov tsis tu ncua.
3. Carbon Fiber Electrode
Cov pa roj carbon fiber ntau yog pheej yig thiab ruaj khov dua li cov pa roj carbon zoo tib yam, nrog cov slag shedding tsawg dua, ua rau lawv tsim nyog rau cov nqi qis qis xws li cov kab hluav taws xob electrolytic.
4. Lead Anode
Ib txwm siv lead ua anodes yog tsawg- nqi tab sis muaj kuab paug heev, yooj yim ua cov hlau lead oxide uas txo cov efficiency, thiab tau maj mam hloov los ntawm titanium- cov ntaub ntawv raws li.
II. Cov lus pom zoo xaiv
Muaj Electrolysis (piv txwv li, chlor-alkali): Titanium-coated anodes yog qhov nyiam, ntsuas qhov ua tau zoo thiab lub neej ntev.
Laboratory/Small-scale Electrolysis: Graphite lossis carbon fiber electrodes muab tus nqi zoo dua-kev ua tau zoo.
Cov Kev Xav Tau Tshwj Xeeb: Rau cov ntawv thov uas xav tau qhov kub thiab txias los yog ib puag ncig huab cua, Hastelloy lossis npib tsib xee - cov ntaub ntawv raws li tuaj yeem txiav txim siab.
III. Lwm yam kev xav
Electrolyte Matching: Cov electrolytes sib txawv (xws li, acidic, alkaline, los yog chlorine-cov tshuab) muaj qhov sib txawv corrosive rau cov ntaub ntawv, xav tau kev xaiv xaiv.
Kev Ntsuam Xyuas Kev Lag Luam: Siab- cov khoom siv nqi (xws li, titanium anodes) yuav tsum tau muaj kev pov thawj ntawm kev siv sij hawm ntev - cov txiaj ntsig los ntawm kev ua neej nyob thiab kev txuag hluav taws xob.
Hauv cov ntsiab lus, titanium-raws li coated anodes tam sim no yog qhov kev xaiv zoo tshaj plaws rau kev lag luam electrolysis, thaum graphite los yog carbon fiber ntau haum rau cov nqi qis - raug nqi. Qhov kev xaiv tshwj xeeb yuav tsum yog raws li kev ua haujlwm tiag tiag thiab pob nyiaj siv.
