Kodi ndi zinthu ziti zomwe zimafunika pokonza pepala la graphite?

Pepala la graphite ndi pepala lapadera lopangidwa ndi graphite. Pamene graphite inkangochotsedwa pansi, inali ngati mamba, ndipo inkatchedwa graphite yachilengedwe. Mtundu uwu wa graphite uyenera kukonzedwa ndi kuyengedwa usanagwiritsidwe ntchito. Choyamba, graphite yachilengedwe imanyowa mu yankho losakanikirana la sulfuric acid yokhazikika ndi nitric acid yokhazikika kwa nthawi, kenako imatsukidwa ndi madzi oyera ndikubowoledwa, kenako nkuyikidwa mu uvuni wotentha kwambiri kuti itenthedwe. Mkonzi wotsatira wa graphite wa Furuite akuwonetsa zofunikira zopangirapepala la graphite:

Popeza kuti graphite imalowa mkati mwachangu ikatenthedwa, nthawi yomweyo, kuchuluka kwa graphite kumawonjezeka mofulumira ndi maulendo makumi angapo kapena mazana ambiri, kotero mtundu wa graphite waukulu umapezeka, womwe umatchedwa "graphite yotupa". Pali mabowo ambiri mu chotupacho.graphite(kumanzere pambuyo poti cholowera chachotsedwa), zomwe zimachepetsa kwambiri kuchuluka kwa graphite kufika pa 0.01 ~ 0.059/cm3, ndi kulemera kopepuka komanso kutentha kwabwino kwambiri. Chifukwa pali mabowo ambiri okhala ndi kukula kosiyanasiyana komanso zokwawa, amatha kulumikizidwa wina ndi mnzake ndi mphamvu yakunja, yomwe ndi kudziphatika kwa graphite yokulirapo. Malinga ndi kudziphatika kumeneku kwa graphite yokulirapo, ikhoza kukonzedwa kukhala pepala la graphite.

Chifukwa chake, chofunikira popanga pepala la graphite ndikukhala ndi zida zonse, zomwe ndi chipangizo chokonzekera graphite yotambasulidwa kuchokera ku kunyowa, kuyeretsa ndi kuyaka, momwe muli madzi ndi moto, zomwe zingayambitse kuphulika, kotero kupanga kotetezeka ndikofunikira kwambiri; Kachiwiri, makina opangira mapepala ndi makina osindikizira ozungulira, kuthamanga kwa mzere wozungulira kwa kusindikiza kozungulira sikuyenera kukhala kokwera kwambiri, apo ayi kudzakhudza kufanana ndi mphamvu ya pepala la graphite, ndipo kuthamanga kwa mzere ndi kochepa kwambiri, zomwe sizingatheke kwambiri. Chifukwa chake, mikhalidwe ya njirayi iyenera kukhala yolondola, ndipographitPepala la e limaopa chinyezi. Pepala lomalizidwa liyenera kukhala lopanda chinyezi, kumbukirani kuti liyenera kukhala losalowa madzi komanso losungidwa bwino.
