Pepala la graphite limagwiritsidwa ntchito kwambiri mu zida zamagetsi, ndipo pepala la graphite limagwiritsidwa ntchito m'mbali zambiri kuti lichotse kutentha. Pepala la graphite limakhalanso ndi vuto la moyo wautumiki panthawi yogwiritsa ntchito, bola ngati njira yogwiritsira ntchito moyenera ingawonjezere moyo wautumiki wa pepala la graphite. Mkonzi wotsatira adzakufotokozerani njira yolondola yowonjezerera moyo wautumiki wa pepala la graphite:
1. Pepala la grafiti likhoza kulumikizidwa motsatizana momwe zingathere. Ngati mtengo wotsutsa wa pepala la graphite suli wofanana, mbale ya graphite yokhala ndi kukana kwakukulu idzakhazikika motsatizana, zomwe zimapangitsa kuti kukana kwa pepala linalake la graphite kuchuluke mofulumira komanso kuti nthawi yake ikhale yochepa.
2. Mphamvu yamagetsi ikagwiritsidwa ntchito pa pepala la graphite, kutentha kwa pamwamba pa pepala la graphite kumakwera. Ndikofunikira kugwiritsa ntchito mphamvu yamagetsi yochepa kwambiri (mphamvu). Chonde dziwani kuti mtengo wolembedwa kumapeto ozizira a pepala la graphite ndi mphamvu yamagetsi ndi magetsi pa 1000 ℃ mumlengalenga, zomwe sizikugwirizana ndi momwe zimagwiritsidwira ntchito. Muzochitika zachizolowezi, mphamvu ya pamwamba pa pepala la graphite imapezeka kuchokera ku ubale wa kutentha mu uvuni ndi kutentha kwa pamwamba. Ndikofunikira kugwiritsa ntchito mphamvu ya pamwamba (W/cm2) ya 1/2 ~ 1/3 ya kuchuluka kwa mphamvu ya mbale ya graphite, ndi pepala la graphite losagwira kutentha kwambiri.
3. Mukagwiritsa ntchito pepala la graphite mosalekeza, akuyembekeza kuti lidzawonjezera kukana pang'onopang'ono kuti likhale ndi moyo wautali.
4. Pakugawa kutentha kwa pepala la graphite, muyezo wowunikira ndi wakuti lili mkati mwa 60 °C mkati mwa nthawi yoyenera ya malungo. Zachidziwikire, kugawa kutentha kudzawonjezeka ndi ukalamba wake, ndipo pamapeto pake kumatha kufika 200 °C. Kusintha kwa kutentha komwe kumagawika kumasiyananso chifukwa cha mlengalenga wosiyana ndi momwe zimagwirira ntchito mu uvuni.
5. Pambuyo poti pepala la graphite litenthedwa mumlengalenga, filimu yolimba ya silicon oxide imapangidwa pamwamba, ndikupanga filimu yoteteza yotsutsana ndi okosijeni, yomwe imagwira ntchito yotalikitsa moyo. M'zaka zaposachedwapa, zokutira zosiyanasiyana zapangidwa kuti zipewe kusweka kwa pepala la graphite kuti ligwiritsidwe ntchito mu uvuni wokhala ndi mpweya wosiyanasiyana.
6. Kutentha kwa pepala la graphite kukakwera, nthawi yogwiritsira ntchito imakhala yochepa. Chifukwa chake, kutentha kwa uvuni kukapitirira 1400 °C, kuchuluka kwa okosijeni kudzawonjezeka ndipo nthawi yogwiritsira ntchito idzafupikitsidwa. Mukagwiritsa ntchito, samalani kuti kutentha kwa pamwamba pa pepala la graphite kusakwere kwambiri.
Pepala la graphite lopangidwa ndi Furuite graphite limapangidwa ndi graphite yotambasulidwa poyizungulira ndi kuiwotcha, ndipo limapirira kutentha kwambiri, kutentha koyenera, kusinthasintha, kulimba komanso kutseka bwino. Ngati mukufuna kugula, chonde funsani.
