I-Carbon Graphite, eyaziwa nangokuthi i-graphite noma i-graphite impahla, iyinto enhle kakhulu yokushisa ephezulu enezimpawu eziningi zokusebenza okuhlaba umxhwele. Ezihlolweni zokushisa okuphezulu, ukuqonda iphuzu elincibilikayo legrafu yekhabhoni kubalulekile njengoba kuthinta ngokuqondile ukuqina kanye nokusebenziseka kwezinto zokwakha ezindaweni ezingemuva kakhulu.
I-Graphite yekhabhoni iyinto ehlanganiswe ama-athomu e-carbon, enezinhlaka ezahlukahlukene zekristali. Isakhiwo se-graphite esivame kakhulu yisakhiwo esinqunyelwe, lapho ama-athomu e-carbon ahlelwe khona ezingxenyeni ze-hexagonal, futhi ukubopha phakathi kwezendlalelo kubuthakathaka, ngakho-ke izingqimba zibuthakathaka, ngakho-ke izingqimba zibuthakathaka kalula. Lesi sakhiwo sifaka i-Carbon GrassTite ngokuvuka okuhle kakhulu okushisayo nokugcona, okwenza kwenze kahle ekushiseni okuphezulu nasezindaweni eziphakeme zokuxabana.
Iphuzu elincibilikayo le-graphite yekhabhoni
Iphuzu lokuncibilika legrafu yekhabhoni libhekisela emazingeni okushisa lapho kuguqulwa i-graphite yekhabhoni kusuka ku-luqiwe kuya koketshezi ngaphansi kwengcindezi evamile yomoya. Iphuzu lokuncibilika legrafu lincike ezicini ezifana nesakhiwo sayo sekristalu kanye nobumsulwa, ngakho-ke kungaba nezinguquko ezithile. Kodwa-ke, ngokuvamile, iphuzu lokuncibilika legrafu liphakathi kobubanzi bokushisa okuphezulu.
Iphuzu le-graphite elijwayelekile livame cishe ama-degree angama-3550 Celsius (noma cishe ama-6422 degrees Fahrenheit). Lokhu kwenza ukuthi i-graphite ibe yinto evunyelwe kakhulu yokuvimbela izinga lokuvimbela izicelo eziphakeme ezilungele izicelo eziphakeme zokushisa okuphezulu, njengokushaya kwensimbi, ukukhiqizwa kwe-arc kagesi, ukukhiqizwa kwe-semiconductor, kanye nezinto zelebhu. Iphoyinti layo eliphakeme eliphakeme linika amandla i-graphite ukuze lilondoloze ukuqina kwalo nokusebenza kwalezi zindawo ezingemuva kakhulu, ngaphandle kokuba zithambekele ekuncibilikiseni noma ekulahlekelweni amandla omshini.
Kodwa-ke, kufanelekile ukuqaphela ukuthi iphuzu lokuncibilika legrafu lihlukile endaweni yalo yokulahla. Yize i-graphite ingancibiliki emazingeni okushisa aphezulu kakhulu, ingashisa ngaphansi kwezimo ezimbi kakhulu (njengezindawo ezicebile umoya-mpilo).
Ukushisa okuphezulu kokushisa kwe-graphite
I-graphite ephezulu idlala indima ebalulekile emikhakheni eminingi, kanti okulandelayo kungenye yezicelo eziphakeme zokushisa okuphezulu:
1. Ukubhema insimbi
Enqubweni yokubhema insimbi, i-graphite ephezulu yokuncibilika ivame ukusetshenziswa njengezakhi ezinjenge-tucibles, ama-electrodes, kanye nezinsimbi zomlilo. Ingakwazi ukubekezelela amazinga okushisa aphezulu kakhulu futhi inokuphakela okuhle okushisayo, okusiza ukuncibilika nokuphonsa izinsimbi.
2. Ukukhiqiza i-semiconductor
Inqubo yokukhiqiza i-semiconductor idinga izinsiza eziphakeme zokushisa ukulungiselela izinto ze-semiconductor ezinjenge-crystalline silico. I-Graphite isetshenziswa kabanzi njengesithando somlilo kanye nento yokushisa ngoba ingasebenza emazingeni okushisa aphezulu kakhulu futhi inikeze ukuvumelanisa okuzinzile.
3. Imboni yamakhemikhali
I-Graphite isetshenziswa embonini yamakhemikhali ukukhiqiza ama-reactors amakhemikhali, amapayipi, izinto zokushisa, kanye nezinto zokusekela ze-catalyst. Ukuqina kokushisa okuphezulu nokuphikiswa kokugqwala kwenza kube yisinqumo esihle sokuphatha izinto ezilimazayo.
4. Isitofu selebhu
Izitovo zelebhu impahla ngokuvamile zisebenzisa i-graphite njengento yokushisa izivivinyo ezahlukahlukene zokushisa okuphezulu nokucutshungulwa kwezinto ezibonakalayo. Ama-graphite ama-brucibles nawo asetshenziselwa ukuncibilika kwesampula nokuhlaziywa okushisayo.
I-5. Imboni ye-aerospace ne-nuclear
Emikhakhani yezimboni ze-aerospace nezenukreni, i-graphite isetshenziselwa ukwenza izinto zokushisa eziphakeme nezinto, njengezinto ezihlabelayo zikaphethiloli ngezinto zokuhlaziya zenuzi.
Ukuhlukahluka kanye nokusetshenziswa kwe-graphite
Ngaphezu kwegrafu ejwayelekile, kunezinhlobo zezinye izinhlobo zokuhlukahluka kwe-carbon graphite, njenge-prographic ye-progytytic, i-graphimed elungisiwe, imidwebo ye-graphiosite yensimbi, njll., Ezinezimpawu zokusebenza ezikhethekile zokushisa okushisa kakhulu.
I-PORTOLYTIC Graphite: Lolu hlobo lwe-graphite lune-anisotropy ephezulu nokuvuselelwa okuhle kakhulu okushisayo. Kusetshenziswa kabanzi emikhakheni efana ne-Aerospace ne-semiconductor imboni.
Modified graphite: By introducing impurities or surface modification into graphite, specific properties can be improved, such as enhancing corrosion resistance or improving thermal conductivity.
Izinto zensimbi ezisuselwa kwe-graphite ezihlangene
Cok.clusion
Indawo ephezulu yokuncibilika ye-carbon graphite yenza kube yinto ebaluleke kakhulu kwizicelo ezahlukahlukene zokushisa okuphezulu. Noma ngabe ekumoyeni kwensimbi, ukukhiqiza okwenziwe nge-semiconductor, imboni yamakhemikhali, noma amafayili welebhu, i-graphite idlala indima ebalulekile ekuqinisekiseni ukuthi lezi zinqubo zingathwalwa ngokukhulu emazingeni okushisa amakhulu. Ngasikhathi sinye, ukwahlukahluka okuhlukile kanye nokuguqulwa kwe-graphite nakho kwenza ilungele izinhlelo ezahlukahlukene ezahlukahlukene, ihlinzeka ngezisombululo ezahlukahlukene zemiphakathi yezimboni neyesayensi. Ngokuthuthuka okuqhubekayo kobuchwepheshe, singalindela ukubona ukuvela kwezinto ezintsha zokushisa okuphezulu ukuze kuhlangatshezwane nezidingo eziguqukayo njalo zezinqubo zokushisa eziphakeme.
