Pepala la graphite limapangidwa ndi graphite yokhala ndi mpweya wambiri wa carbon flake kudzera mu mankhwala ndi kugwedezeka kwa kutentha kwambiri. Mawonekedwe ake ndi osalala, opanda thovu loonekera, ming'alu, makwinya, mikwingwirima, zinyalala ndi zolakwika zina. Ndi chinthu choyambira popanga zisindikizo zosiyanasiyana za graphite. Chimagwiritsidwa ntchito kwambiri potseka makina, mapaipi, mapampu ndi ma valve mwamphamvu komanso mosasunthika mumagetsi, mafuta, mankhwala, zida, makina, diamondi ndi mafakitale ena. Ndi chinthu chatsopano chotseka chomwe chingagwiritsidwe ntchito m'malo mwa zisindikizo zachikhalidwe monga rabara, fluoroplastics ndi asbestos.
Mafotokozedwe a pepala la graphite amadalira kwambiri makulidwe ake. Pepala la graphite lokhala ndi mafotokozedwe ndi makulidwe osiyanasiyana limagwiritsidwa ntchito mosiyanasiyana. Pepala la graphite limagawidwa m'magulu awiri: pepala losinthasintha la graphite, pepala la graphite lopyapyala kwambiri, pepala la graphite lotsekedwa, pepala la graphite lotenthetsera kutentha, pepala la graphite loyendetsa, ndi zina zotero. Mitundu yosiyanasiyana ya pepala la graphite Imatha kugwira ntchito yake m'magawo osiyanasiyana amafakitale.
Makhalidwe 6 a pepala la graphite:
1. Kusavuta kukonza: Pepala la grafiti likhoza kudulidwa mosiyanasiyana kukula, mawonekedwe ndi makulidwe, ndipo matabwa osalala odulidwa mosiyanasiyana akhoza kuperekedwa, ndipo makulidwe ake akhoza kukhala kuyambira 0.05 mpaka 1.5m.
2. Kukana kutentha kwambiri: kutentha kwakukulu kwa pepala la graphite kumatha kufika 400℃, ndipo kutentha kochepa kungakhale kotsika kuposa -40℃.
3. Kutentha kwambiri: Kutentha kwakukulu kwa pepala la graphite kumatha kufika 1500W/mK, ndipo kukana kutentha kumakhala kotsika ndi 40% kuposa kwa aluminiyamu ndi 20% kuposa kwa mkuwa.
4. Kusinthasintha: Pepala la grafiti lingapangidwe mosavuta kukhala ma laminate ndi chitsulo, chotetezera kutentha kapena tepi ya mbali ziwiri, zomwe zimapangitsa kuti kapangidwe kake kakhale kosinthasintha ndipo kangakhale ndi guluu kumbuyo.
5. Kupepuka ndi kupyapyala: Pepala la grafiti ndi lopepuka ndi 30% kuposa aluminiyamu yofanana kukula kwake ndipo ndi lopepuka ndi 80% kuposa mkuwa.
6. Kugwiritsa ntchito mosavuta: Sinki yotenthetsera ya graphite ikhoza kumangiriridwa bwino pamalo aliwonse athyathyathya komanso opindika.
Mukasunga pepala la graphite, samalani ndi zinthu ziwiri izi:
1. Malo osungira: Pepala la graphite ndiloyenera kuyikidwa pamalo ouma komanso athyathyathya, ndipo silimawotchedwa ndi dzuwa kuti lisaphwanye. Pakupanga, limachepetsa kugundana; lili ndi mphamvu yoyendetsera magetsi, kotero likafunika kusungidwa, liyenera kusungidwa kutali ndi gwero lamagetsi.
2. Kuletsa kusweka: Pepala la graphite ndi lofewa kwambiri, tingalidule malinga ndi zofunikira, kuti lisasweke panthawi yosungira, siliyenera kupindika kapena kupindika pang'ono. Zinthu zonse za pepala la graphite ndizoyenera kudula mapepala.
