Graphite imagawidwa kukhala graphite yachilengedwe ndi graphite yopanga. Anthu ambiri amadziwa koma sadziwa kusiyanitsa. Kodi pali kusiyana kotani pakati pawo? Mkonzi wotsatirawa akuwuzani momwe mungasiyanitsire ziwirizi:
1. Kapangidwe ka kristalo
Natural graphite: Kukula kwa kristalo kumakhala kokwanira, digiri ya graphitization ya flake graphite ndi yoposa 98%, ndipo digiri ya graphitization yachilengedwe ya microcrystalline graphite nthawi zambiri imakhala pansi pa 93%.
graphite Yopanga: Mlingo wa chitukuko cha kristalo umadalira zopangira komanso kutentha kwa kutentha. Nthawi zambiri, kutentha kwa kutentha kwapamwamba, kumapangitsa kuti graphitization ikhale yokwera. Pakali pano, digiri ya graphitization ya yokumba graphite opangidwa makampani zambiri zosakwana 90%.
2. Kapangidwe ka bungwe
Natural flake graphite: Ndi kristalo umodzi wokhala ndi mawonekedwe osavuta ndipo imakhala ndi zolakwika za crystallographic (monga zolakwika za mfundo, kusokonezeka, zolakwika za stacking, etc.), ndipo imawonetsa mawonekedwe a anisotropic pamlingo wa macroscopic. Njere za graphite yachilengedwe ya microcrystalline ndi yaying'ono, mbewuzo zimasanjidwa bwino, ndipo pali pores pambuyo pochotsa zonyansa, kuwonetsa isotropy pamlingo wa macroscopic.
Kupanga graphite: Iwo akhoza kuonedwa ngati Mipikisano gawo zinthu, kuphatikizapo graphite gawo otembenuzidwa kuchokera carbonaceous particles monga petroleum coke kapena phula coke, graphite gawo otembenuzidwa kuchokera malasha phula binder wokutidwa mozungulira particles, tinthu kudzikundikira kapena malasha phula phula. The pores opangidwa ndi binder pambuyo kutentha mankhwala, etc.
3. Maonekedwe athupi
Ma graphite achilengedwe: nthawi zambiri amakhala ngati ufa ndipo amatha kugwiritsidwa ntchito okha, koma nthawi zambiri amagwiritsidwa ntchito limodzi ndi zida zina.
graphite yokumba: Pali mitundu yambiri, kuphatikizapo ufa, CHIKWANGWANI ndi chipika, pamene yokumba graphite m'lingaliro yopapatiza nthawi zambiri chipika, amene ayenera kukonzedwa mu mawonekedwe enaake ntchito.
4. Thupi ndi mankhwala katundu
Pazinthu zakuthupi ndi zamankhwala, ma graphite achilengedwe ndi ma graphite ochita kupanga ali ndi zofanana komanso zosiyana pakuchita. Mwachitsanzo, zonse zachilengedwe graphite ndi yokumba graphite ndi conductors wabwino wa kutentha ndi magetsi, koma graphite ufa wa chiyero chomwecho ndi tinthu kukula, zachilengedwe flake graphite ali bwino kutentha kutengerapo ntchito ndi madutsidwe magetsi, akutsatiridwa ndi masoka microcrystalline graphite ndi yokumba graphite. . otsikitsitsa. Graphite imakhala ndi mafuta abwino komanso mapulasitiki ena. Kukula kwa kristalo wa flake graphite wachilengedwe kumakhala kokwanira, kugundana kocheperako ndi kochepa, kutsekemera kwabwino kwambiri, ndipo pulasitiki ndiyokwera kwambiri, kutsatiridwa ndi wandiweyani wa crystalline graphite ndi cryptocrystalline graphite, kutsatiridwa ndi graphite yokumba. osauka.
Qingdao Furuite Graphite makamaka chinkhoswe woyera masoka graphite ufa, pepala graphite, mkaka graphite ndi mankhwala ena graphite. Kampaniyo imayika kufunikira kwakukulu kwa ngongole kuti iwonetsetse kuti zinthu zili bwino. Makasitomala ali olandiridwa kuti mutilankhule.
