Graphition electrode thiab inert Electrode: Qhov kev coj ua ntawm cov tshuaj lom neeg ntiaj teb

Nyob rau hauv lub ntiaj teb zoo ntawm chemistry, electrodes yog zoo li cov "Cov Tub Rog" ntawm kev ntws ntawm cov tshuab hluav taws xob thiab taw qhia qhov kev kawm tau ntawm ntau yam tshuaj lom neeg. Ntawm lawv, graphite electrodes thiab inert electrodes tau dhau los ua kev saib xyuas zoo hauv kev saib xyuas Chemistry nrog lawv cov khoom siv dav dav thiab dav. Niaj hnub no, cia peb ua kom tob tob ntawm ob qho hluav taws xob.
1. Graphite electrode: ib qho kev nyuaj "Carbon Hero"
Graphite, ib qho ua lead ua ke ntawm cov roj carbon ntau, muaj ib qho cim fawm txheej txheem. Cov pa roj carbon atoms hauv txhua txheej yog sib txuas zoo los ntawm kev sib txuas lus mesh ua rau ib tug hexagonal planacar Mesh cov qauv, thaum cov khaubncaws sab nraud povtseg nrog txhua lwm yam los ntawm cov neeg tsis muaj zog los ntawm cov rog tsis muaj zog. Tus qauv tshwj xeeb no muab cov khoom muaj ntau ntau yam zoo tshaj plaws, ua rau nws cov khoom zoo rau kev ua cov elecodes.
1. Kev ua haujlwm zoo
Muaj ntau cov tshuab hluav taws xob dawb hauv cov khaubncaws sab nraud ntawm cov khaubncaws sab nraud povtseg, ib yam li cov tsheb tsav tsheb dawb rau cov kev loj, muab ib qho chaw tsis muaj kev sib raug zoo. Yog li no, graphite hluav taws xob muaj hluav taws xob zoo heev, tuaj yeem hloov hluav taws xob zoo, thiab ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntau yam electrochemical.
2. Cov tshuaj ruaj khov
Nyob rau hauv chav tsev kub, cov tshuaj muaj zog ntawm graphite yog ruaj khov thiab nws tsis yooj yim kom hnov ​​cov tshuaj nrog lwm yam tshuaj. Qhov no yog vim tias lub zog sib txuas zog nruab nrab ntawm cov pa roj carbon atoms hauv graphite loj, ua cov qauv molecular ntawm cov teeb meem ruaj khov. Qhov kev ruaj khov no ua kom cov hluav taws xob graphite los tswj lawv tus qauv thiab kev ua tau zoo nyob rau hauv ntau yam ntawm ntau yam kev ua haujlwm ntawm lub sij hawm ntev.
3. Lub zog kub siab tiv taus
Graphite muaj ib qho siab melting taw tes thiab tuaj yeem tiv taus qhov ntsuas ntawm qhov chaw kub kub. Ntawm qhov kub thiab txias, graphite cov hluav taws xob tsis yooj yim rau yaj lossis deform, thiab tseem tuaj yeem tswj hwm kev ua haujlwm zoo thiab kev ntseeg siab. Cov yeeb yam no ua rau graphite electrodes indispensable nyob rau hauv ntau lub siab- cov txheej txheem hluav taws xob, xws li cov hluav taws kub thiab kev lag luam aluminium ntau lawm.
4. Peb thov thoob plaws
(1) hluav taws xob rauv taws ua haujlwm steelmaking: hauv cov txheej txheem hluav taws xob hluav taws xob, graphite ultrasonic- kub arcs, thiab yaj tus nqi nrawm. Lub siab zoo thiab kub ua rau ntawm graphite cov hluav taws xob ua kom cov txheej txheem statmaking zoo thiab ruaj khov.
(2) Kev Lag Luam Electrolysis Ntau Lawm: Hauv txhuas electrolysis tsim tau, graphite electrodes yog siv ua anodes ntawm cov electrolytic cells. Los ntawm electrolying aluminium oxide, hlau nplaum txhuas yog tau txais ntawm lub Cathoo, thaum lub graphite electrode koom nrog oxidize oxygen oxygen.
Txij li cov txheej txheem hluav taws xob yuav tsum tau nqa tawm ntawm cov hluav taws xob siab, qhov zoo ntawm graphite hluav taws xob hauv cov pa hluav taws xob muaj peev xwm siv tau.
(3) Kev Ntsuam Xyuas Electrochical: Hauv Electrochemical Kev sim, Graphite cov hluav taws xob feem ntau yog siv los ua cov tshuaj ua haujlwm lossis cov hluav taws xob ua haujlwm. Nws txoj kev ua tau zoo thiab tshuaj muaj kuab lom tau muab cov txheej txheem ruaj khov thiab cov kws tshawb fawb zoo tshaj plaws rau cov txheej txheem tshuaj xyuas thiab txheeb xyuas cov khoom siv hluav taws xob muaj ntau yam.
