Monga tonse tikudziwa, graphite ili ndi makhalidwe abwino kwambiri omwe zipangizo zina zachitsulo sizingasinthe. Monga chinthu chomwe chimakondedwa, zipangizo za graphite electrode nthawi zambiri zimakhala ndi makhalidwe ambiri osokoneza pakusankha kwenikweni kwa zipangizo. Pali maziko ambiri osankha zipangizo za graphite electrode, koma pali mfundo zinayi zazikulu:
Pazinthu zomwe zili ndi kukula kwa tinthu tating'onoting'ono kofanana, mphamvu ndi kuuma kwa zinthu zomwe zili ndi resistivity yochepa ndizochepa pang'ono kuposa zomwe zili ndi resistivity yayikulu. Izi zikutanthauza kuti, liwiro lotulutsa ndi kutayika kwake zidzakhala zosiyana. Chifukwa chake, resistivity yeniyeni ya zinthu za graphite electrode ndi yofunika kwambiri pakugwiritsa ntchito moyenera. Kusankha zipangizo za electrode kumagwirizana mwachindunji ndi momwe kutulutsa kumakhudzira. Kwambiri, kusankha zipangizo kumatsimikizira mikhalidwe yomaliza ya liwiro lotulutsa, kulondola kwa makina ndi kukhwima kwa pamwamba.
Mu makampani apadera a graphite, muyezo woyesera kuuma ndi njira yoyesera kuuma ya Shore, yomwe mfundo yake yoyesera ndi yosiyana ndi yachitsulo. Ngakhale kuti mukumvetsa kwathu pang'ono za graphite, nthawi zambiri imaonedwa ngati chinthu chofewa. Koma deta yeniyeni yoyesera ndi momwe imagwiritsidwira ntchito zikuwonetsa kuti kuuma kwa graphite ndikokwera kuposa kwa zipangizo zachitsulo. Chifukwa cha kapangidwe ka graphite kokhala ndi zigawo, imakhala ndi magwiridwe antchito abwino kwambiri odulira. Mphamvu yodulira ndi pafupifupi 1/3 yokha ya zinthu zamkuwa, ndipo pamwamba pake pali makina opangidwa mosavuta.
Komabe, chifukwa cha kuuma kwake kwakukulu, kutayika kwa zida kudzakhala kwakukulu pang'ono kuposa zida zodulira zitsulo podula. Nthawi yomweyo, zinthu zomwe zili ndi kuuma kwakukulu zimakhala ndi mphamvu yabwino kwambiri yowongolera kutayika kwa kutulutsa. Chifukwa chake, kuuma kwa Shore kwa zinthu za graphite electrode ndi chimodzi mwazinthu zomwe mungasankhe pazinthu za graphite electrode.
Kenako pali mphamvu yopindika ya zipangizo za graphite electrode. Mphamvu yopindika ya zipangizo za graphite electrode ndi chiwonetsero chachindunji cha mphamvu ya zipangizo, kusonyeza kufupika kwa kapangidwe ka mkati mwa zipangizo. Zinthu zomwe zili ndi mphamvu zambiri zimakhala ndi mphamvu yoteteza kutulutsa madzi. Kwa electrode yomwe ili ndi kulondola kwakukulu, zinthu zomwe zili ndi mphamvu yabwino ziyenera kusankhidwa momwe zingathere.
Pomaliza, kukula kwa tinthu tating'onoting'ono ta zinthu za graphite electrode, kukula kwa tinthu tating'onoting'ono ta zinthu za graphite electrode kumakhudza mwachindunji momwe zinthu zimatulutsidwira. Kukula kwa tinthu tating'onoting'ono tambiri kumakhala kochepa, kutulutsa kofanana, kumakhala kokhazikika komanso khalidwe labwino la pamwamba pake. Kukula kwa tinthu tating'onoting'ono tambiri, kuthamanga kwa kutulutsa kumathamanga komanso kutayika kwa roughing kumachepa. Chifukwa chachikulu ndichakuti mphamvu yotulutsa imasiyana malinga ndi mphamvu yamagetsi panthawi yotulutsa. Komabe, kutha kwa pamwamba pambuyo potulutsa kumasiyana malinga ndi kusintha kwa tinthu tating'onoting'ono.
Ma electrode a grafiti akhoza kukhala chisankho choyamba cha zipangizo m'makampani. Chifukwa chakuti ma electrode a grafiti ali ndi ubwino wabwino kwambiri, njira yoyenera yosankhira ma electrode a grafiti ndi kusankha ma electrode awiriawiri oyenera a grafiti ndizofunikira kwambiri.
