Graphite bepa ipepa rakakosha rakagadzirwa negraphite. Apo graphite yakanga ichangobva kucherwa pasi, yakanga yakangoita sezvikero, uye yainzi natural graphite. Rudzi urwu rwegraphite inofanirwa kurapwa nekunatswa isati yashandiswa. Kutanga, iyo yakasikwa graphite yakanyoroveswa mune yakasanganiswa mhinduro ye concentrated sulfuric acid uye yakadzika nitric acid kwenguva yakati, yozoshambidzwa nemvura yakachena uye yakafinhwa, uye yozoiswa muchoto chepamusoro-soro chekupisa. Iyo inotevera Furuite graphite mupepeti inosuma izvo zvekutanga zvekugadziragraphite bepa:
Nekuti iyo inlay pakati pegraphite inoputika nekukurumidza mushure mekupisa, panguva imwecheteyo, vhoriyamu yegraphite inowedzera nekukurumidza nemakumi kana mazana enguva, saka rudzi rweyakafara graphite inowanikwa, iyo inonzi "kuzvimba graphite". Pane maburi akawanda akazvimbagraphite(yakasara mushure mokunge inlay yabviswa), iyo inoderedza zvakanyanya kurongedza kwe graphite kusvika ku 0.01 ~ 0.059 / cm3, ine uremu huremu uye yakanakisa kupisa kupisa. Nekuti kune makomba akawanda ane hukuru hwakasiyana uye scraggy, anogona kuvharirwa mumwe nemumwe crisscross nekunze kwesimba, inova yekuzvinamira yeakawedzera graphite. Zvinoenderana neiyi yekuzvinamatira yeakawedzera graphite, inogona kugadziriswa kuita graphite bepa.
Naizvozvo, chinodiwa pakugadzirwa kwepepa regraphite kuve neseti yakakwana yemidziyo, ndiko kuti, mudziyo wekugadzirira yakawedzera girafu kubva pakunyorova, kuchenesa uye kupisa, umo mune mvura nemoto, izvo zvinogona kutungamirira kuputika, saka. kugadzirwa kwakachengeteka kunonyanya kukosha; Chechipiri, kugadzira mapepa uye roller kudzvanya michina, iyo mutsara yekumanikidza yekutsikirira haifanire kunge yakanyanya kukwirira, zvikasadaro ichakanganisa kufanana uye kusimba kwebepa regraphite, uye mutsara wekumanikidza idiki, izvo zvinotonyanya kusagoneka. Nokudaro, maitiro ekugadzirisa anofanirwa kuve akarurama, uyegraphite bepa rinotya unyoro. Pepa rakapedzwa rinofanira kunge rakaputirwa nekunyorova, rangarira kusapinda mvura uye kuchengetedzwa zvakanaka.
