Pepa reGraphite ipepa rakakosha rakagadzirwa negraphite. Graphite payaingocherwa kubva pasi, yaingova semakwenzi, uye yainzi natural graphite. Rudzi urwu rwegraphite runofanira kugadziriswa nekunatswa risati rashandiswa. Kutanga, graphite yechisikigo inonyikwa mumusanganiswa wesulfuric acid yakasanganiswa nenitric acid yakasanganiswa kwenguva yakati, yozogezwa nemvura yakachena yoboorwa, yozoiswa muchoto chinopisa zvakanyanya kuti chipiswe. Mupepeti weGraphite weFuruite anotevera anounza zvinodiwa pakugadzira.bepa regirafiti:
Nekuti girafu iri pakati pegirafu inopwa nekukurumidza mushure mekudziya, panguva imwe chete, huwandu hwegirafu hunowedzera nekukurumidza kagumi kana kunyange mazana, saka mhando yegirafu yakafara inowanikwa, iyo inonzi "girafu yakazvimba". Kune maburi akawanda mugirafu yakazvimba.girafiti(inosara mushure mekunge girafu yabviswa), izvo zvinoderedza zvakanyanya huwandu hwegirafiti kusvika pa0.01 ~ 0.059/cm3, nehuremu hwakareruka uye kupisa kwakanaka. Nekuti kune makomba akawanda ane saizi dzakasiyana uye akakwenenzverwa, anogona kuvharirwa pamwe chete nesimba rekunze, iro rinova iro rinonamira wega wegirafiti yakawedzerwa. Zvichienderana neizvi, girafiti yakawedzerwa inogona kugadzirwa kuita bepa regirafiti.
Saka, chinodiwa pakugadzira bepa regrafiti ndechekuva nemidziyo yakakwana, kureva kuti, mudziyo wekugadzira girafiti yakawedzerwa kubva mukunyikwa, kuchenesa nekupisa, umo mune mvura nemoto, izvo zvinogona kukonzera kuputika, saka kugadzirwa kwakachengeteka kwakakosha zvikuru; Chechipiri, michina yekugadzira mapepa neroller pressure, linear pressure yekudzvanya roller haifanirwe kunge yakakwira zvakanyanya, zvikasadaro ichakanganisa kufanana nesimba rebepa regrafiti, uye linear pressure idiki kwazvo, izvo zvinotonyanya kusakwanisika. Nokudaro, mamiriro ekuita anofanira kunge akarurama, uyegirafitiBepa remagetsi rinotya hunyoro. Bepa rapera rinofanira kunge rakaputirwa risingapindi hunyoro, yeuka kuti haripindi mvura uye rakachengetedzwa zvakanaka.
