Pepala la graphite ndi pepala lapadera lopangidwa ndi graphite. Pamene graphite idangokumbidwa pansi, Unali ngati mamba, ndipo amatchedwa graphfute yachilengedwe. Zojambula zamtunduwu ziyenera kuthandizidwa ndikutsukidwa isanagwiritsidwe ntchito. Choyamba, chithunzi chachilengedwe chimanyowa mu yankho losakanizika la sulufuric acid ndi nitric acid kwakanthawi, kenako ndikutsukidwa ndi madzi owoneka bwino ndikuwotcha. Pulogalamu yotsatirayi ya furuite yolemba imayambitsa njira zopangirapepala la graphite:
Chifukwa chopindika pakati pa graphite chimasandulika mwachangu pambuyo pa kutentha, nthawi yomweyo, kuchuluka kwa graphite kumawonjezera mwachangu ndi ma graphite ambiri, omwe amatchedwa "graphite" wotupa ". Pali mabowo ambiri otupagilaphite(Kumanzere pambuyo pa inchiy imachotsedwa), yomwe imachepetsa chipata chojambulira graphite mpaka 0.01 ~ 0.059 / cm3, ndi kulemera bwino ndi kuthira bwino kwambiri. Chifukwa pali zingwe zambiri zokhala ndi zingwe zosiyanasiyana, zimatha kuphatikizidwa wina ndi mnzake ndi mphamvu yakunja, yomwe imapangitsa kuti zikhale zolimbana ndi graphite yokulitsidwa. Malinga ndi izi zotsatsa izi zokutira zokutira, zimatha kukonzedwa mu pepala lopindika.
Chifukwa chake, chofunikira pakupanga pepala la graphite ndikuyenera kukhala ndi zida zonse ziwiri, ndiye kuti chipangizo chokonzekera chikukula, kuyeretsa ndi kuwotcha, komwe kumatha kuphulika, komwe kumatha kuphulika, motero kumakhala kotetezeka kwambiri. Kachiwiri, makina opanga mapepala komanso osokoneza bongo, kutengera mzere wozungulira wozungulira sikuyenera kukhala lalitali kwambiri, apo ayi kutengera mwayi wokulirapo, uzidzakhudzanso kufanana ndi pepala la graphite, ndipo kupsinjika ndi kochepa kwambiri. Chifukwa chake, njirazi ziyenera kukhala zolondola, ndipogituloE pepala ndikuopa chinyezi. Pepala lomalizidwa liyenera kukhala chinyezi-chonyowa, kumbukirani kukhala madzi osokoneza bongo ndikusungidwa bwino.
