Pepala la graphite limapangidwa ndi graphite yapamwamba kwambiri ya carbon flake kudzera mumankhwala opangira mankhwala komanso kutentha kwambiri. Maonekedwe ake ndi osalala, opanda thovu zoonekeratu, ming'alu, makwinya, zokopa, zonyansa ndi zina zolakwika. Ndiwo maziko opangira zisindikizo zosiyanasiyana za graphite. Amagwiritsidwa ntchito kwambiri kusindikiza makina, mapaipi, mapampu ndi mavavu mu mphamvu yamagetsi, mafuta, mankhwala, zida, makina, diamondi ndi mafakitale ena. Ndi chinthu chatsopano chosindikizira chatsopano chosinthira zisindikizo zachikhalidwe monga labala, fluoroplastics ndi asibesitosi. .
Mafotokozedwe a pepala la graphite makamaka amadalira makulidwe ake. Mapepala a graphite okhala ndi mawonekedwe ndi makulidwe osiyanasiyana ali ndi ntchito zosiyanasiyana. Mapepala a graphite amagawidwa kukhala mapepala osinthika a graphite, mapepala apamwamba kwambiri a graphite, mapepala a graphite osindikizidwa, mapepala a graphite a thermally conductive, conductive graphite paper, etc.
Makhalidwe 6 a pepala la graphite:
1. Kusavuta kukonza: Mapepala a graphite akhoza kufa-kudulidwa mu kukula kwake, mawonekedwe ndi makulidwe osiyanasiyana, ndi matabwa odulidwa odulidwa angaperekedwe, ndipo makulidwe ake amatha kuchokera ku 0.05 mpaka 1.5m.
2. Kukana kutentha kwakukulu: kutentha kwakukulu kwa pepala la graphite kumatha kufika 400 ℃, ndipo osachepera akhoza kukhala otsika kuposa -40 ℃.
3. Kutentha kwapamwamba kwambiri: Kuthamanga kwapamwamba kwambiri mu ndege ya pepala la graphite kumatha kufika 1500W / mK, ndipo kukana kwa kutentha ndi 40% kutsika kuposa aluminium ndi 20% kutsika kuposa mkuwa.
4. Kusinthasintha: Mapepala a graphite amatha kupangidwa mosavuta kukhala laminates ndi zitsulo, zosanjikiza zosanjikiza kapena tepi yamagulu awiri, zomwe zimawonjezera kusinthasintha kwa mapangidwe ndipo zimatha kukhala ndi zomatira kumbuyo.
5. Kupepuka ndi kuonda: Mapepala a graphite ndi 30% opepuka kuposa aluminiyumu ya kukula kwake ndi 80% yopepuka kuposa mkuwa.
6. Kusavuta kugwiritsa ntchito: Sinki yotentha ya graphite imatha kumangirizidwa bwino pamalo aliwonse athyathyathya komanso opindika.
Posunga mapepala a graphite, samalani ndi zinthu ziwiri izi:
1. Malo osungiramo zinthu: Mapepala a graphite ndi abwino kwambiri kuikidwa pamalo owuma ndi athyathyathya, ndipo sakhala padzuwa kuti apewe kufinya. Panthawi yopanga, imatha kuchepetsa kugundana; ili ndi mlingo wina wa conductivity, kotero pamene ikufunika kusungidwa, iyenera kusungidwa kutali ndi gwero la mphamvu. waya wamagetsi.
2. Pewani kusweka: Mapepala a graphite ndi ofewa kwambiri, tikhoza kudula molingana ndi zofunikira, kuti tiwateteze kusweka panthawi yosungiramo, sikuyenera kupindika kapena kupindika ndi kupindika pang'ono. Mapepala amtundu wa graphite ndi oyenera kudula m'mapepala.
