Graphite foda wani nau'in kayan foda ne mai kyau wanda aka yi da carbon bayan pyrolysis mai zafi mai zafi ko carbonization, kuma babban sashinsa shine carbon. Graphite foda yana da tsari na musamman mai launi, wanda shine baki launin toka ko haske baki. Nauyin kwayoyin sa shine 12.011.
Ana iya taƙaita halayen graphite foda kamar haka:
1. High conductivity da thermal conductivity: graphite foda ne mai kyau conductive da thermal conductivity abu, tare da high thermal conductivity da conductivity. Wannan ya samo asali ne saboda ƙaƙƙarfan tsari da tsarin sifofi na carbon atom a cikin graphite, wanda ke sauƙaƙa wa electrons da zafi don gudanar da su.
2. Kyakkyawan rashin ƙarfi na sinadarai: graphite foda yana da kyakkyawan kwanciyar hankali da rashin aiki a ƙarƙashin yanayin al'ada, kuma baya amsawa tare da yawancin abubuwa. Wannan kuma shi ne dalilin da ya sa graphite foda ne yadu amfani a cikin filaye na lantarki da sinadaran kayan, high zafin jiki lalata kariya, da dai sauransu.
3. Yana da wasu ƙarfin injiniya: idan aka kwatanta da sauran nano-materials, graphite foda yana da tasiri mafi girma, juriya na extrusion da juriya, wanda zai iya bunkasa kayan aikin injiniya na kayan zuwa wani matsayi.
Hanyoyin shirye-shirye na graphite foda suna da yawa, kuma hanyoyin gama gari sune kamar haka:
1. Pyrolysis a high zafin jiki: zafi na halitta graphite ko chemically hada graphite crystal zuwa high zafin jiki (sama da 2000 ℃) to bazuwa shi a cikin graphite foda.
2. High-zazzabi carbonization Hanyar: graphite foda aka samu ta hanyar sinadaran dauki graphite tare da albarkatun kasa da Layer tsarin kama da graphite. Dangane da kayan albarkatun kasa daban-daban, ana iya raba shi zuwa hanyoyin shirye-shirye daban-daban, kamar haɓakar tururin sinadarai, pyrolysis da carbonization.
3. Mechanical Hanyar: ta hanyar inji nika da nunawa ayyuka, na halitta graphite ko roba graphite kayan da ake sarrafa don samun graphite foda.
Hanyoyi daban-daban na shirye-shiryen suna da tasiri daban-daban akan inganci, tsabta da ilimin halittar jiki na graphite foda. A aikace-aikace masu amfani, hanyoyin shirye-shiryen da suka dace suna buƙatar zaɓar bisa ga buƙatu daban-daban.
1. Kayan lantarki da sinadarai: graphite foda za a iya shirya a cikin conductive da thermal conductive polymer composites, wanda aka yi amfani da lantarki na'urorin, batura, conductive tawada da sauran filayen. Alal misali, a cikin kayan lantarki, graphite foda na iya ƙara yawan aiki na kayan, inganta aikin lantarki na lantarki, da kuma tsawaita rayuwar baturi.
2. Rufe kayan: graphite foda za a iya amfani da shirye-shiryen na daban-daban coatings, kamar anti-lalata shafi, thermal conductivity shafi, electromagnetic garkuwa shafi, da dai sauransu A cikin filayen mota, jirgin sama, yi, da dai sauransu, da coatings shirya. tare da graphite foda zai iya inganta juriya na ultraviolet da lalata juriya na kayan.
3. Catalyst: Za'a iya amfani da foda na Graphite don shirye-shiryen mai kara kuzari, kuma ana amfani da shi sosai a cikin ƙwayoyin halitta, samar da sinadarai da sauran filayen. Alal misali, a cikin hydrogenation na kayan lambu mai, graphite foda bayan jiyya za a iya amfani da a matsayin mai kara kuzari don inganta dauki selectivity da yawan amfanin ƙasa.
4. Kayan yumbura: A cikin shirye-shiryen kayan yumbura, graphite foda zai iya inganta ƙarfin injinsa da sauran kaddarorin ta hanyar ƙarfafawa. Musamman a cikin cermets da yumbu mai laushi, ana amfani da foda mai graphite sosai.
