- Ukwakheka kwesayizi yezinhlayiya yezinhlayiya kubhekisele kwingxenye yezinhlayiya zosayizi abahlukahlukene. Ukuxuba izinhlayiya zamazinga ahlukene ngesilinganiso esithile kunokuba usebenzise uhlobo olulodwa lwezinhlayiyana ukwenza imikhiqizo ye-graphite ye-elekthrodi ibe nobuningi obuphakeme, amandla anele okusebenza. Ngemuva kokuxuba izinhlayiya zosayizi abahlukahlukene ngokwengxenye, izikhala phakathi kwezinhlayiya ezinkulu zingagcwaliswa yizinhlayiya ezincane noma i-powder. Lokhu kuyafana nomphumela wokuxuba amatshe amatshe, isihlabathi, kanye nosimende ngokwesilinganiso lapho ulungiselela ukhonkolo. Kodwa-ke, ukuhlukaniswa kwemikhiqizo ye-graphite ye-elekthrodi ngokusho kobukhulu bezinhlayiyana akukhona ukuthuthukisa ubukhulu bomkhiqizo, ukunciphisa i-poor youst, futhi uthole amandla anele okwenziwa ngomshini, kodwa futhi neminye imisebenzi.
Izinhlayiya ezinkulu zidlala indima yamathambo ekwakhekeni kwemikhiqizo ye-graphite electrode. Ukwandisa kahle usayizi nenani lezinhlayiya ezinkulu kungathuthukisa ukumelana nokudlidliza okushisayo komkhiqizo (okungekho lula ukuqhekeka ngesikhathi sokupholisa okusheshayo nokushisa) futhi kunciphise ukukhishwa kwemali okushisayo komkhiqizo. Ngaphezu kwalokho, kunemifantu embalwa nemikhiqizo yemfucumfucu yezinqubo zokucindezela nokubhaka yomkhiqizo. Kodwa-ke, uma kunezinhlayiya eziningi kakhulu kakhulu, i-polosion yomkhiqizo izokwenyusa kakhulu, ukuncipha kuzokwehla, futhi amandla omshini azokwehla. Ngaphezu kwalokho, kunzima ukuthi umkhiqizo uzuze indawo ebushelelezi ngesikhathi sokulungiswa.
Umsebenzi wezinhlayiya ezincane ukugcwalisa izikhala phakathi kwezinhlayiya ezinkulu. Inani lezinhlayiya ezincane eziyimpuphu livame ukubalwa ngengxenye enkulu ngesikhathi sokulungiselela izithako, kwesinye isikhathi kufinyelela kuma-60% kuye ku-70%. Ukwandisa kahle inani lezinhlayiya ezincane eziyimpuphu zinganciphisa ukuqina komkhiqizo, zithuthukise ubuntu namandla emishini, futhi benze ingaphezulu lomkhiqizo bushelelezi ngesikhathi sokucutshungulwa. Kodwa-ke, inani elikhulu kakhulu lezinhlayiya ezincane eziyimpuphu zizokhulisa kakhulu amathuba okuqhekeka komkhiqizo ezinqubweni kanye nokuqhekeka kwe-graphitization, nokumelana nokuvukwa kwe-ixivation kwemikhiqizo ye-graphite ye-electrode kuzokwehla ngesikhathi sokusetshenziswa. Ngaphezu kwalokho, kusetshenziswa izinhlayiya ezincane eziyimpuphu, kudingeka umthamo omkhulu wokunamathela. Izinga lekhabhoni elisele le-binder (Coal Tar Pitch) ngemuva kokukhala ngokuvamile cishe ngo-50%. Ngakho-ke, ukusetshenziswa ngokweqile kwezinhlayiya ezincane eziyimpuphu akunayo inzuzo enkulu ngekhwalithi yomkhiqizo ophelile. Izinhlobo ezahlukahlukene kanye nokucaciswa kwemikhiqizo ye-graphite ye-elekthreyithi zinokuhlanganiswa okuhlukile kosayizi wezinhlayiyana.
