Mapepala a graphite amagwiritsidwa ntchito kwambiri pazida zamagetsi, ndipo mapepala a graphite amagwiritsidwa ntchito m'madera ambiri kuti athetse kutentha. Mapepala a graphite adzakhalanso ndi vuto la moyo wautumiki pakagwiritsidwe ntchito, bola ngati njira yolondola yogwiritsira ntchito ingathe kuwonjezera moyo wautumiki wa pepala la graphite. Mkonzi wotsatira akufotokozerani njira yolondola yowonjezerera moyo wautumiki wa pepala la graphite:
1. Mapepala a graphite akhoza kugwirizanitsidwa mofanana momwe angathere. Ngati mtengo wotsutsa wa pepala la graphite suli wofanana, mbale ya graphite yokhala ndi kukana kwakukulu idzakhazikika mndandanda, zomwe zimapangitsa kuti pakhale kuwonjezeka kofulumira kwa kukana kwa pepala linalake la graphite ndi moyo wofupikitsidwa.
2. Kuchuluka kwazomwe zimagwiritsidwa ntchito pa pepala la graphite, ndipamwamba kutentha kwa pamwamba pa pepala la graphite. Ndibwino kuti mugwiritse ntchito kachulukidwe kakang'ono kwambiri kamene kali pamwamba (mphamvu). Chonde dziwani kuti mtengo womwe udalembedwa kumapeto kozizira kwa pepala la graphite ndi waposachedwa komanso voteji pa 1000 ℃ mumlengalenga, zomwe sizikugwirizana ndi kugwiritsa ntchito kwenikweni. Nthawi zonse, mphamvu ya pamwamba ya pepala la graphite imapezeka kuchokera ku chiyanjano pakati pa kutentha kwa ng'anjo ndi kutentha kwa pamwamba. Ndi bwino kugwiritsa ntchito pamwamba mphamvu (W/cm2) wa 1/2 ~ 1/3 wa kachulukidwe malire a mbale graphite, ndi kutentha kugonjetsedwa ndi pepala graphite.
3. Mukamagwiritsa ntchito mapepala a graphite mosalekeza, akuyembekeza kuonjezera kukana pang'onopang'ono kuti mukhale ndi moyo wautali.
4. Kwa mawonekedwe a kutentha kwa pepala la graphite, muyezo woyendera ndikuti uli mkati mwa 60 ° C mkati mwa utali wotentha wa kutentha. Zachidziwikire, kugawidwa kwa kutentha kumawonjezeka ndi kukalamba kwake, ndipo pamapeto pake kumatha kufika 200 ° C. Kusintha kwapadera kwa kutentha kwapadera kumakhalanso kosiyana chifukwa cha mlengalenga wosiyana ndi zochitika zogwirira ntchito mu ng'anjo.
5. Pambuyo pa kutenthedwa kwa pepala la graphite mumlengalenga, filimu yowonongeka ya silicon oxide imapangidwa pamwamba, imapanga filimu yoteteza anti-oxidative, yomwe imathandizira kukulitsa moyo. M’zaka zaposachedwapa, zokutira zosiyanasiyana zapangidwa pofuna kupewa kung’amba mapepala a graphite kuti agwiritsidwe ntchito m’ng’anjo zokhala ndi mpweya wosiyanasiyana.
6. Kutentha kwapamwamba kwa ntchito ya pepala la graphite, kumachepetsa moyo wautumiki. Chifukwa chake, kutentha kwa ng'anjo kukapitilira 1400 ° C, kuchuluka kwa okosijeni kudzakulitsidwa ndipo moyo wautumiki udzafupikitsidwa. Mukamagwiritsa ntchito, samalani kuti musalole kutentha kwa pepala la graphite kukhala kokwera kwambiri.
Pepala la graphite lopangidwa ndi Furuite graphite limapangidwa ndi graphite yokulitsidwa pogudubuza ndikuwotcha, ndipo imakhala ndi kukana kutentha kwambiri, kusinthasintha kwamafuta, kusinthasintha, kulimba mtima komanso kusindikiza bwino. Ngati muli ndi zosowa zilizonse zogula, chonde omasuka kufunsa.
