Graphite imagawidwa m'magulu awiri: graphite yachilengedwe ndi graphite yopangidwa. Anthu ambiri amadziwa koma sadziwa momwe angawasiyanitsire. Kodi pali kusiyana kotani pakati pawo? Mkonzi wotsatira adzakuuzani momwe mungasiyanitsire pakati pa awiriwa:
1. Kapangidwe ka kristalo
Graphite yachilengedwe: Kukula kwa kristalo kumakhala kokwanira, digiri ya graphitization ya flake graphite ndi yoposa 98%, ndipo digiri ya graphitization ya graphite yachilengedwe ya microcrystalline nthawi zambiri imakhala pansi pa 93%.
Graphite Yopangira: Mlingo wa chitukuko cha kristalo umadalira zinthu zopangira ndi kutentha kwa chithandizo cha kutentha. Kawirikawiri, kutentha kwa chithandizo cha kutentha kukakhala kwakukulu, mlingo wa graphitization umakwera. Pakadali pano, mlingo wa graphitization wa graphite yopangira yomwe imapangidwa m'mafakitale nthawi zambiri ndi wochepera 90%.
2. Kapangidwe ka bungwe
Graphite yachilengedwe: Ndi galasi limodzi lokhala ndi kapangidwe kosavuta ndipo lili ndi zolakwika za kristalo (monga zolakwika za mfundo, kusokonekera, zolakwika zomangira, ndi zina zotero), ndipo limasonyeza makhalidwe a anisotropic pamlingo wa macroscopic. Tinthu ta graphite yachilengedwe ya microcrystalline ndi tating'ono, tinthu tating'onoting'ono timakonzedwa molakwika, ndipo pali ma pores pambuyo poti zonyansa zachotsedwa, zomwe zimasonyeza isotropy pamlingo wa macroscopic.
Graphite yopangira: Itha kuonedwa ngati chinthu chokhala ndi magawo ambiri, kuphatikiza gawo la graphite losinthidwa kuchokera ku tinthu ta carbonaceous monga petroleum coke kapena pitch coke, gawo la graphite losinthidwa kuchokera ku coal tar binder yozunguliridwa ndi tinthu tating'onoting'ono, kusonkhanitsa tinthu tating'onoting'ono kapena coal tar pitch. Ma pores opangidwa ndi binder pambuyo pa kutentha, ndi zina zotero.
3. Mawonekedwe enieni
Grafiti yachilengedwe: nthawi zambiri imapezeka mu mawonekedwe a ufa ndipo ingagwiritsidwe ntchito yokha, koma nthawi zambiri imagwiritsidwa ntchito limodzi ndi zinthu zina.
Grafiti yopangira: Pali mitundu yambiri, kuphatikizapo ufa, ulusi ndi chipika, pomwe graphite yopangira m'lingaliro lopapatiza nthawi zambiri imakhala chipika, chomwe chimayenera kukonzedwa kukhala mawonekedwe enaake chikagwiritsidwa ntchito.
4. Kapangidwe ka thupi ndi mankhwala
Ponena za makhalidwe a thupi ndi mankhwala, graphite yachilengedwe ndi graphite yopangira zinthu zili ndi kufanana komanso kusiyana kwa magwiridwe antchito. Mwachitsanzo, graphite yachilengedwe ndi graphite yopangira zinthu zonse ndi zoyendetsa bwino kutentha ndi magetsi, koma ufa wa graphite womwe uli ndi chiyero chofanana ndi kukula kwa tinthu tating'onoting'ono, graphite yachilengedwe yokhala ndi mawonekedwe osalala imakhala ndi mawonekedwe abwino kwambiri osinthira kutentha ndi ma conductivity amagetsi, kutsatiridwa ndi graphite yachilengedwe yokhala ndi mawonekedwe osalala komanso graphite yopangira zinthu. Graphite ili ndi mawonekedwe abwino komanso mawonekedwe osalala. Kukula kwa kristalo kwa graphite yachilengedwe yokhala ndi mawonekedwe osalala kumakhala kokwanira, coefficient ya friction ndi yaying'ono, lubricity ndiye yabwino kwambiri, ndipo plasticity ndiye yapamwamba kwambiri, kutsatiridwa ndi graphite yolimba ya crystalline ndi cryptocrystalline graphite, kutsatiridwa ndi graphite yopangira zinthu.
Qingdao Furuite Graphite imagwiritsa ntchito ufa wachilengedwe wa graphite, mapepala a graphite, mkaka wa graphite ndi zinthu zina za graphite. Kampaniyo imaona kuti ngongole ndi yofunika kwambiri kuti zinthuzo zikhale zapamwamba. Makasitomala alandiridwa kuti alankhule nafe.
