Njengoko sonke sisazi, i-graphite ineempawu ezikumgangatho ophezulu ezingenakutshintshwa zezinye izinto zesinyithi. Njengezinto ezikhethwayo, izixhobo ze-graphite electrode zihlala zineempawu ezininzi ezididayo ekukhetheni izinto. Kukho iziseko ezininzi zokukhetha izixhobo ze-graphite electrode, kodwa kukho iindlela ezine eziphambili:
Kwizinto ezinobukhulu obufanayo be-particle, amandla kunye nobunzima bezinto ezinokumelana okuphantsi nazo ziphantsi kancinci kunezo zinokuxhathisa okuphezulu. Oko kukuthi, isantya sokukhupha kunye nokulahleka kuya kwahluka. Ke ngoko, ukumelana okungaphakathi kwezinto ze-graphite electrode kubaluleke kakhulu ekusetyenzisweni okusebenzayo. Ukukhethwa kwezinto ze-electrode kunxulumene ngokuthe ngqo nesiphumo sokukhupha. Kangangoko, ukukhethwa kwezinto kumisela iimeko zokugqibela zesantya sokukhupha, ukuchaneka komatshini kunye noburhabaxa bomphezulu.
Kwishishini legrafiti ekhethekileyo, umgangatho oqhelekileyo wovavanyo lobunzima yindlela yovavanyo lobunzima beShore, apho umgaqo wovavanyo wahlukile kowesinyithi. Nangona ngokwengqiqo yethu engaphantsi kwengqondo yegrafiti, ngokubanzi ithathwa njengesixhobo esithambileyo. Kodwa idatha yovavanyo kunye nokusetyenziswa kwayo kubonisa ukuba ubunzima begrafiti buphezulu kunobo bezinto zesinyithi. Ngenxa yesakhiwo segrafiti esineeleya, inokusebenza kakuhle kokusika kwinkqubo yokusika. Amandla okusika amalunga ne-1/3 yezinto zobhedu, kwaye umphezulu ochwetheziweyo kulula ukuwuphatha.
Nangona kunjalo, ngenxa yobunzima bayo obuphezulu, ukuguguleka kwezixhobo kuya kuba kukhulu kancinci kunokwezixhobo zokusika zesinyithi xa zisikwa. Kwangaxeshanye, izinto ezinobunzima obuphezulu zinolawulo oluhle kakhulu lokulahleka kokukhupha. Ke ngoko, ubunzima be-Shore bezinto ze-graphite electrode bukwayenye yeendlela zokukhetha izinto ze-graphite electrode.
Emva koko kukho amandla okugoba kwezinto ze-graphite electrode. Amandla okugoba kwezinto ze-graphite electrode kukubonakalisa ngokuthe ngqo amandla ezinto, okubonisa ubuncinci besakhiwo sangaphakathi sezinto. Izinto ezinamandla aphezulu zinokuxhathisa ukuguguleka kokukhupha. Kwi-electrode echanekileyo kakhulu, izinto ezinamandla angcono kufuneka zikhethwe kangangoko kunokwenzeka.
Okokugqibela, ububanzi obuphakathi bee-particle zezinto ze-graphite electrode, ububanzi obuphakathi bee-particle zezinto ze-graphite electrode buchaphazela ngokuthe ngqo imeko yokukhupha izinto. Okukhona ubukhulu obuphakathi bee-particle buncinci, kokukhona ukukhupha kufana ngakumbi, kokukhona imeko yokukhupha izinzile kwaye umgangatho womphezulu uba ngcono. Okukhona ubukhulu bee-particle bukhulu, kokukhona isantya sokukhupha sikhawuleza kwaye kokukhona ukulahleka kwe-roughing kuncinci. Isizathu esiphambili kukuba amandla okukhupha ayahluka ngokobukhulu bangoku ngexesha lenkqubo yokukhupha. Nangona kunjalo, ukugqitywa komphezulu emva kokukhupha kuyahluka ngokutshintsha kwee-particle.
Ii-electrode zegrafiti zinokuba lolona khetho lokuqala lwezinto ezisetyenziswa kushishino. Kungenxa yokuba ii-electrode zegrafiti zineengenelo ezingenakuthelekiswa nanto, nto leyo ebaluleke kakhulu kukukhetha ii-electrode zegrafiti kunye nokukhethwa kwee-electrode zegrafiti ezifanelekileyo.
