Kwindawo yokufumana iinkqubo zemizi-mveliso, i-electrode idlala indima ebaluleke kakhulu ekuqhubeni umbane kwaye iququzelele ukuphendula ezahlukeneyo zeekhemikhali. Phakathi kweentlobo ezahlukeneyo ze-electrodes ezisetyenzisiweyo, igrafu kunye nekhabhoni ye-elecbon zima ngaphandle njengokhetho oluqhelekileyo, nganye ineempawu ezizodwa kunye nokusetyenziswa kwezicelo. Ngelixa zombini zivela kwikhabhoni, zahlukile kwilungiselelo labo lokulwa, iipropathi, kunye nokufaneleka kweenjongo ezithile.
Ukungafikeleli kwindawo yolwakhiwo: I-phygrite vs. carbon
Umahluko osisiseko phakathi kwegrafu kunye nekhabhoni ilele kwilungiselelo labo leatomic:
• igrafu:Igrafu eqhayisa ngesakhiwo se-crystalline, apho i-athom acom ye-carbon icwangciswe e-Hexagonal Faked) omnye komnye. Ezi zixhobo zidityaniswe kunye, zivumela intshukumo elula yee-elektroni phakathi kwazo, zidlulisela igrafu ngombane obalaseleyo.
•Ikharbon:I-carbon, kwelinye icala, idibanisa isiseko esibanzi sezinto ezibanzi, kubandakanya ikharfon echaziweyo (i-Crystalline ye-Crystalline), i-carbon ye-ragbon (i-cirbon efakwe kwigrafu), kunye nee-atom ze-subbon (ii-tublon). Ukuqhutywa kombane kwekhabhoni kuyahluka ngokuxhomekeke kwifom kunye nesakhiwo sayo.
Iipropathi ezibekelwa zodwa: I-phybon vs i-carbon electrodes
Umahluko phakathi kolwakhiwo phakathi kwegrafu kunye nekhabhoni kubonakaliswa kwiipropathi zabo ezahlukeneyo:
•Ukuqhutywa kombane:Igrafu ngokubanzi ibonisa ukuqhutywa kombane okuphezulu kuthelekiswa neendlela ezininzi zekhabhoni. Le ndawo yenza igrafu ukhetho olukhethileyo lwezicelo apho kufuneka khona imibane ephezulu, njengeziko lombane kunye nebhetri.
•Amandla oomatshini:Ikhabhoni Electrode, ngakumbi ezo zenziwa kwikhabhoni yegrafire, zihlala zinamandla amakhulu kunefomati ecocekileyo. La mandla aphuculweyo abenza bafaneleke kwizicelo apho i-electrode iphantsi koxinzelelo, njenge-Arc Welcling kunye ne-electrolysis.
•Ukulahla inkundla:Isakhiwo somzobo sinokwenza ukuba sichaphazeleke ngakumbi uhlaselo lweekhemikhali xa kuthelekiswa neendlela zekhabhoni. Nangona kunjalo, zombini igrafu kunye nekharbon inokubonakalisa ukwenziwa kweekhemikhali kwiindawo ezithile, ipropathi esetyenziswa kwizicelo ezinjenge-chlor-alkali ectrolysis kunye ne-aluminium shlelysis.
Izicelo zivelelwe:
Iipropathi ezizodwa zegrafu kunye ne-carbon electrodes zenza zilungele uluhlu ezahlukeneyo lwezicelo:
• Igrafu eleimation electrode:
° Iziko lombane:Ukuqhutywa komgangatho ofanelekileyo kwenza ukuba ilungele ukusetyenziswa kwiziko lombane, apho lisebenza njengento yokufudumeza ukunyibilika izinyithi.
Ibhetri e-elektroni:Isakhono segraphite sokukhosela i-Instha i-lithium le-lithium lenza ukuba ibe yinto ephambili kwiibhetri zeLithium-ion.
I-electrolysis:Igrafu eleckiterodes iqashwe kwiinkqubo ezahlukeneyo ze-electrolysis, ezinje ngemveliso ye-chlorine kunye nesodium hydroxide.
• I-Carbon electrodes:
I-Arc yelsI-Carbon electrodes isetyenziswa ngokubanzi kwi-Arc Welding, apho babonelela khona i-arc yombane enyibilikisi intsimbi yefilitha.
I-electrolysis:Iindlela ezithile zekhabhoni yekhabhoni, ngakumbi i-carbon yegraphithi, isetyenziswa kwiinkqubo ze-electrolysis, ezinjenge swelinum swelting.
° Eclect yoMbane (EDM):I-Carbon Electrodes iqashwe e-EDM, indlela yokhetho echanekileyo esebenzisa iintlantsi zombane ukuze ikhuphe izinto ze-erode.
Ukukhetha i-electrode elungileyo yomsebenzi
Ukukhetha phakathi kwegrafu kunye ne-elecbon electrodes kuxhomekeke kwisicelo esithile kunye neepropathi ezinqwenelekayo. Igrafu egqwesileyo kwizicelo ezifuna ukwenziwa kombane okuphezulu, ngelixa i-Carbon Electrodes inokuthandwa ngamandla abo okanye ukumelana nemichiza. Ukujonga ngononophelo kwiimfuno zokusetyenziswa okucetywayo kuya kukhokela ukukhetha ezona zinto zifanelekileyo ze-electrode.
