I-graphite ihlukaniswe yaba yi-graphite yemvelo kanye ne-synthetic graphite. Abantu abaningi bayazi kodwa abazi ukuthi bangazihlukanisa kanjani. Uyini umehluko phakathi kwabo? Umhleli olandelayo uzokutshela ukuthi ungahlukanisa kanjani kokubili:
1. Isakhiwo sekristalu
I-graphite yemvelo: Ukuthuthukiswa kwekristalu kuphelele, izinga le-graphitization ye-flake graphite lingaphezu kuka-98%, futhi izinga le-graphitization ye-graphite yemvelo ye-microcrystalline ngokuvamile lingaphansi kwe-93%.
I-graphite yokwenziwa: Izinga lokuthuthukiswa kwekristalu lincike ezintweni ezingavuthiwe kanye nezinga lokushisa lokwelashwa kokushisa. Ngokuvamile, izinga lokushisa lokwelashwa liphakeme, izinga le-graphitization liphezulu. Njengamanje, izinga le-graphitization le-graphite yokwenziwa ekhiqizwa embonini ngokuvamile lingaphansi kwama-90%.
2. Isakhiwo senhlangano
I-graphite ye-flake yemvelo: Ikristalu eyodwa enesakhiwo esilula futhi inokukhubazeka kwe-crystallographic kuphela (njengokulimala kwamaphuzu, ukugudluka, amaphutha wokupakisha, njll.), futhi ibonisa izici ze-anisotropic ezingeni le-macroscopic. Izinhlamvu ze-graphite yemvelo ye-microcrystalline zincane, okusanhlamvu kuhlelwe ngendlela ehlelekile, futhi kukhona ama-pores ngemva kokususwa kokungcola, okubonisa i-isotropy ezingeni le-macroscopic.
I-graphite yokwenziwa: Ingathathwa njengento enezigaba eziningi, okuhlanganisa isigaba segraphite esiguqulelwe ezinhlayiyeni ze-carbonaceous ezifana ne-petroleum coke noma i-pitch coke, isigaba se-graphite esiguqulwa sisuka ku-coal tar binder esongelwe izinhlayiya, ukunqwabelana kwezinhlayiyana noma i-tiyela yamalahle. Ama-pores akhiwe yi-binder ngemva kokwelashwa kokushisa, njll.
3. Isimo somzimba
I-graphite yemvelo: imvamisa ikhona ngesimo sempushana futhi ingasetshenziswa yodwa, kodwa ivame ukusetshenziswa ngokuhambisana nezinye izinto.
I-graphite yokwenziwa: Kunezinhlobo eziningi, okuhlanganisa impushana, i-fiber kanye ne-block, kuyilapho i-graphite yokwenziwa ngomqondo omncane ngokuvamile i-block, okudingeka icutshungulwe ibe yisimo esithile lapho isetshenziswa.
4. Izakhiwo zomzimba namakhemikhali
Ngokuphathelene nezakhiwo zomzimba namakhemikhali, i-graphite yemvelo kanye ne-graphite yokwenziwa inokubili okufana nokuhluka ekusebenzeni. Isibonelo, kokubili i-graphite yemvelo kanye ne-graphite yokufakelwa kukhona abaqhubi abahle bokushisa nogesi, kodwa ngezimpushana ze-graphite zokuhlanzeka okufanayo nosayizi wezinhlayiyana, i-graphite yemvelo ye-flake inomsebenzi ongcono kakhulu wokudlulisa ukushisa kanye nokuhamba kukagesi, kulandelwa i-graphite yemvelo ye-microcrystalline kanye ne-graphite yokufakelwa. . ephansi kakhulu. I-graphite ine-lubricity enhle kanye ne-plasticity ethile. Ukuthuthukiswa kwekristalu ye-graphite ye-flake yemvelo kuphelele, i-coefficient ye-friction incane, i-lubricity ihamba phambili, futhi i-plasticity iphakeme kakhulu, ilandelwa i-crystalline graphite eminyene kanye ne-cryptocrystalline graphite, ilandelwa i-graphite yokwenziwa. mpofu.
I-Qingdao Furuite Graphite igxile kakhulu kumpushana we-graphite wemvelo, iphepha le-graphite, ubisi lwe-graphite neminye imikhiqizo ye-graphite. Inkampani ibheka ukubaluleka okukhulu kwesikweletu ukuze kuqinisekiswe izinga eliphezulu lemikhiqizo. Amakhasimende amukelekile ukuthi asithinte.
