I-Graphite ihlukaniswe yaba yi-graphite yemvelo kanye ne-graphite yokwenziwa. Abantu abaningi bayayazi kodwa abazi ukuthi bangayihlukanisa kanjani. Yimiphi umehluko phakathi kwayo? Umhleli olandelayo uzokutshela ukuthi ungahlukanisa kanjani phakathi kwalokhu okubili:
1. Isakhiwo sekristalu
I-graphite yemvelo: Ukuthuthukiswa kwekristalu kuphelele, izinga le-graphitization ye-flake graphite lingaphezu kuka-98%, kanti izinga le-graphitization ye-microcrystalline graphite yemvelo livame ukuba ngaphansi kuka-93%.
I-graphite yokwenziwa: Izinga lokuthuthukiswa kwekristalu lincike ezintweni zokusetshenziswa kanye nokushisa kokwelashwa kokushisa. Ngokuvamile, uma izinga lokushisa lokwelashwa kokushisa liphakeme, izinga lokuguqulwa kwe-graphit liphakeme. Njengamanje, izinga lokuguqulwa kwe-graphit ye-graphite yokwenziwa ekhiqizwa embonini ngokuvamile lingaphansi kuka-90%.
2. Isakhiwo senhlangano
I-Natural flake graphite: Iyikristalu eyodwa enesakhiwo esilula futhi inamaphutha e-crystallographic kuphela (njengokuphuka kwamaphuzu, ukuhlukana, amaphutha okuhlanganisa, njll.), futhi ikhombisa izici ze-anisotropic ezingeni le-macroscopic. Izinhlayiya ze-microcrystalline graphite yemvelo zincane, izinhlamvu zihlelwe ngendlela engahlelekile, futhi kunezimbobo ngemva kokususwa kokungcola, okubonisa i-isotropy ezingeni le-macroscopic.
I-graphite yokwenziwa: Ingabhekwa njengento enezigaba eziningi, kufaka phakathi isigaba se-graphite esiguqulwe kusuka ezinhlayiyeni ze-carbonaceous njenge-petroleum coke noma i-pitch coke, isigaba se-graphite esiguqulwe kusuka ku-coal tar binder esigoqwe ngezinhlayiya, ukuqongelela kwezinhlayiya noma i-coal tar pitch. Ama-pores akhiwe yi-binder ngemuva kokwelashwa ngokushisa, njll.
3. Isimo somzimba
I-graphite yemvelo: ivame ukuba khona ngesimo sempuphu futhi ingasetshenziswa yodwa, kodwa ivame ukusetshenziswa kanye nezinye izinto.
I-graphite yokwenziwa: Kunezinhlobo eziningi, okuhlanganisa i-powder, i-fiber kanye ne-block, kanti i-graphite yokwenziwa ngomqondo omncane ivame ukuba yi-block, okudingeka icutshungulwe ibe yisimo esithile uma isetshenziswa.
4. Izakhiwo zomzimba nezamakhemikhali
Ngokuphathelene nezakhiwo zomzimba nezamakhemikhali, i-graphite yemvelo kanye ne-graphite yokwenziwa zinezinto ezifanayo kanye nokwehluka ekusebenzeni. Isibonelo, zombili i-graphite yemvelo kanye ne-graphite yokwenziwa ziyizikhombisi ezinhle zokushisa nogesi, kodwa kuma-graphite powders anobumsulwa obufanayo kanye nosayizi wezinhlayiya, i-graphite yemvelo ye-flake inokusebenza okuhle kakhulu kokudlulisa ukushisa kanye nokuqhuba kagesi, kulandelwe yi-microcrystalline graphite yemvelo kanye ne-graphite yokwenziwa. Ephansi kakhulu. I-Graphite inokugcoba okuhle kanye nokuqina okuthile. Ukuthuthukiswa kwekristalu kwe-graphite yemvelo ye-flake kuphelele, i-friction coefficient incane, ukugcoba kungcono kakhulu, kanti ukuqina okuphezulu kakhulu, kulandelwe yi-dense crystalline graphite kanye ne-cryptocrystalline graphite, kulandelwe yi-artificial graphite.
I-Qingdao Furuite Graphite isetshenziswa kakhulu ekukhiqizeni i-graphite yemvelo emsulwa, iphepha le-graphite, ubisi lwe-graphite neminye imikhiqizo ye-graphite. Le nkampani ibheka ukubaluleka okukhulu kwesikweletu ukuqinisekisa ikhwalithi ephezulu yemikhiqizo. Amakhasimende amukelekile ukuxhumana nathi.
