Indlela yokwahlula i-graphite yendalo kunye ne-graphite yokwenziwa

I-Graphite yahlulwe yaba yi-graphite yendalo kunye ne-graphite yokwenziwa. Abantu abaninzi bayayazi kodwa abazi ukuba bazahlula njani. Zithini umahluko phakathi kwayo? Umhleli olandelayo uza kukuxelela indlela yokwahlula phakathi kwezi zimbini:

1. Ulwakhiwo lwekristale
I-graphite yendalo: Uphuhliso lwekristale luphelele, inqanaba le-graphitization ye-flake graphite lingaphezulu kwe-98%, kwaye inqanaba le-graphitization ye-microcrystalline graphite yendalo lidla ngokuba ngaphantsi kwe-93%.
I-graphite yokwenziwa: Ubungakanani bophuhliso lwekristale buxhomekeke kwizinto eziluhlaza kunye nobushushu bonyango lobushushu. Ngokubanzi, xa ubushushu bonyango lobushushu buphezulu, kokukhona inqanaba le-graphitization liphezulu. Okwangoku, ubungakanani be-graphitization ye-graphite yokwenziwa eveliswa kushishino ludla ngokuba ngaphantsi kwe-90%.
2. Ulwakhiwo lombutho
I-Natural flake graphite: Yikristale enye enesakhiwo esilula kwaye ineziphene zekristale kuphela (ezifana neziphene zenqaku, ukudilika, iimpazamo zokubeka izinto, njl.njl.), kwaye ibonisa iimpawu ze-anisotropic kwinqanaba le-macroscopic. Iinkozo ze-natural microcrystalline graphite zincinci, iinkozo zicwangciswe ngendlela engacwangciswanga, kwaye kukho ii-pores emva kokuba ukungcola kususiwe, nto leyo ebonisa i-isotropy kwinqanaba le-macroscopic.
I-graphite yokwenziwa: Ingathathwa njengesixhobo esinezigaba ezininzi, kuquka isigaba se-graphite esiguqulwe kwiinxalenye ze-carbonaceous ezifana ne-petroleum coke okanye i-pitch coke, isigaba se-graphite esiguqulwe kwi-coal tar binder ejikelezileyo kwiinxalenye, ukuqokelelwa kweenxalenye okanye i-coal tar pitch. Ii-pores ezenziwe yi-binder emva konyango lobushushu, njl.njl.
3. Imo ebonakalayo
Igrafiti yendalo: idla ngokubakho ngohlobo lwepowder kwaye ingasetyenziswa yodwa, kodwa idla ngokusetyenziswa kunye nezinye izinto.
I-graphite yokwenziwa: Kukho iintlobo ezininzi, kuquka umgubo, ifayibha kunye nebhloko, ngelixa i-graphite yokwenziwa ngokwengqiqo encinci idla ngokuba yibhloko, ekufuneka icutshungulwe ibe yimo ethile xa isetyenziswa.
4. Iimpawu zomzimba nezekhemikhali
Ngokweempawu zomzimba nezekhemikhali, i-graphite yendalo kunye ne-graphite yokwenziwa zifana kwaye zahlukile ekusebenzeni. Umzekelo, zombini i-graphite yendalo kunye ne-graphite yokwenziwa zii-conductor ezilungileyo zobushushu nombane, kodwa kwi-graphite powders ezinobunyulu obufanayo kunye nobukhulu be-particle, i-natural flake graphite inokusebenza okuhle kokudlulisa ubushushu kunye nokuqhuba kombane, ilandelwa yi-microcrystalline graphite yendalo kunye ne-graphite yokwenziwa. I-Graphite inobunyulu obuhle kunye ne-plasticity ethile. Uphuhliso lwekristale lwe-natural flake graphite luphelele, i-friction coefficient incinci, i-lubricity yeyona ilungileyo, kwaye i-plasticity yeyona iphezulu, ilandelwa yi-dense crystalline graphite kunye ne-cryptocrystalline graphite, ilandelwa yi-artificial graphite.
I-Qingdao Furuite Graphite isebenza kakhulu kumgubo wegraphite wendalo ococekileyo, iphepha legraphite, ubisi lwegraphite kunye nezinye iimveliso zegraphite. Le nkampani iwubeka phambili kakhulu umba wetyala ukuqinisekisa umgangatho ophezulu weemveliso. Abathengi bamkelekile ukuba banxibelelane nathi.
