Graphite bepa ipepa rakakosha rinogadziriswa kubva kugraphite seyakagadzirwa. Apo graphite yakanga ichangobva kucherwa pasi, yakanga yakangoita sezvikero, uye yakanga yakapfava uye yainzi natural graphite. Iyi graphite inofanirwa kugadziriswa nekunatswa kuitira kuti ibatsire. Kutanga, sora magirafu echisikigo mumusanganiswa we-concentrated sulfuric acid uye concentrated nitric acid kwenguva yakati, wozoitora kunze, woisuka nemvura, woiomesa, wozoiisa muchoto chekupisa. Iyo inotevera Furuite graphite mupepeti inosuma zvinodikanwa pakugadzirwa kwepepa regraphite:
Nekuti iyo inlays pakati pemagraphite inoputika nekukurumidza mushure mekupisa, uye panguva imwecheteyo, vhoriyamu yegraphite inokurumidza kuwedzera nemakumi kana kunyange mazana enguva, saka rudzi rweyakafara graphite inowanikwa, iyo inonzi "yakawedzera graphite". Kune mhango yakawanda (yakasara mushure mokunge inlays yabviswa) mu graphite yakawedzerwa, iyo inoderedza zvakanyanya kuwanda kwegirafu, iyo 0.01-0.059 / cm3, chiedza muhuremu uye yakanakisisa mukupisa kupisa. Nekuti kune maburi akawanda, hukuru hwakasiyana, uye kusaenzana, anogona kuyambuka-ayambutsana kana simba rekunze rinoshandiswa. Uku ndiko kuzvinamatira kwe graphite yakawedzerwa. Zvinoenderana nekuzvinamatira kweiyo yakawedzera graphite, inogona kugadziriswa kuita graphite bepa.
Naizvozvo, chinodiwa pakugadzirwa kwepepa regraphite kuve neseti yakakwana yemidziyo, ndiko kuti, mudziyo wekugadzirira yakawedzera graphite kubva mukunyudzwa, kuchenesa, kupisa, nezvimwewo, umo mune mvura nemoto. Zvinonyanya kukosha; yechipiri ndeyekugadzira mapepa uye kudzvanya roller muchina. Mutsara wekumanikidza weiyo inotsikirira roller haifanirwe kunge yakanyanya kukwirira, zvikasadaro ichakanganisa kuenzana uye kusimba kwebepa regraphite, uye kana iyo mutsara kudzvinyirira kuri kudiki, zvinotonyanya kusagamuchirwa. Nokudaro, mamiriro ekugadzirisa maitiro anofanirwa kuve akarurama, uye pepa re graphite rinotya kunyorova, uye pepa rakapedzwa rinofanira kuvharwa mukuputira-kunyorova uye kuchengetwa zvakanaka.
