Vim li cas graphite xaiv raws li cov khoom electrode hauv cov txheej txheem electrolysis, thiab dab tsi zoo nws muaj?
Graphite hluav taws xob tau siv dav hauvElololsissis- tus txheej txheem uas sivCov Hluav Taws Xob Hluav Taws Xob Uas Tsis Txaus Ntshai Tsis -} kev piv txwv tshuaj{{0 {}} vim lawvCov Hluav Taws Xob Hluav Taws Xob, Kev Siv Tshuaj Lom, Thermal Stability, thiab Tus Nqi- Ua Tau ZooCov. Cov khoom siv no graphite aKev xaiv zoo tagnrho rau kev siv raws li ob leeg anodes thiab CathodesNyob rau hauv ntau yam ntawm cov ntawv thov electrolytic.
Cov kev siv ntawm graphite hauv electrolysis
1.Aluminium Ntau Lawm (Hall - héroult txheej txheem)
• Graphite electrodes yog siv los uaTus tsaTxhawm rau ua hluav taws xob hauv cov elevina ntawm alumina (al₂o₃) yaj nyob rau hauv molten cryolite.
• Cov txheej txheem yuav tsum muaj qhov kub nyob ib puag ncig950-980 Qib, Thiab graphite anode fineilitates tusOxidation ntawm Oxygen ES, Uas ces hnov mob nrog cov pa roj carbon los uaCov pa roj carbon dioxide (pa).
• Txawm hais tias graphite anode yogNpluasThaum lub sij hawm cov tshuaj tiv thaiv, nws ua tau zoo, kev ua tau zoo, thiab tiv taus rau siab kub ua kom nws haum rau cov txheej txheem.
2.Dej Electrolysis (Hydrogen Ntau Lawm)
•HauvAlkaline lossis Acidic Dej Electrolysis, Graphite hluav taws xob yog siv rauKev sib cais dej (h₂o) rau hauv hydrogen (h₂) thiab oxygen (O₂).
•Graphite yogChemically ruaj khov nyob rau hauv ob leeg alkaline thiab acidic electrolytes, Thiab nwsResistS corrosionThaum ua kom zoo ua hluav taws xob.
3.Chlor - Alkali Txheej Txheem
•Graphite tau muaj keeb kwm siv ua ib qhoNaj hoomHauv kev tsim covChlorine, hydrogen, thiab sodium hydroxideCov. Txawm hais tias qhov tsawg kawg nkaus anodes (DSA, ua los ntawm titanium coated nrog noble hlau) tau hloov graphite nyob rau hauv ntau kis, graphite tseem siv nyob qhov twgTus nqi thiab cov mob tshwj xeeb nyiam nws.
