Graphite foda wani abu ne wanda ke da matukar damuwa ga halayen sinadaran.A cikin yanayi daban-daban, tsayayyarsa zai canza, wanda ke nufin ƙimar juriya zai canza.Duk da haka, akwai abu ɗaya da ba ya canzawa.Graphite foda yana ɗaya daga cikin kyawawan abubuwan da ba na ƙarfe ba.Matukar ana ajiye foda mai graphite ba tare da katsewa a cikin wani abu da aka keɓe ba, kuma za a iya ba da wutar lantarki kamar siririyar waya.Duk da haka, babu wani madaidaicin lamba don ƙimar juriya, Domin kauri na graphite foda ya bambanta, ƙimar juriya na graphite foda kuma zai bambanta lokacin amfani da kayan aiki da wurare daban-daban.Saboda tsarinsa na musamman, graphite yana da kaddarorin musamman masu zuwa:
1) High zafin jiki resistant irin: da narkewa batu na graphite ne 3850 ± 50 ℃, da kuma tafasar batu ne 4250 ℃.Ko da an ƙone ta da ultra high zafin jiki arc, da nauyi asara da coefficient na thermal fadada su ne kadan.Ƙarfin graphite yana ƙaruwa da zafin jiki, kuma a 2000 ℃, ƙarfin graphite ya ninka.
2) Conductivity da thermal conductivity: The conductivity na graphite ne 100 sau fiye da na talakawa ma'adinai wadanda ba karfe.Ƙarfin zafin jiki ya zarce na kayan ƙarfe kamar ƙarfe, ƙarfe, da gubar.Ƙarfin zafin jiki yana raguwa tare da ƙara yawan zafin jiki, kuma ko da a yanayin zafi mai girma, graphite ya zama insulator.
3) Lubricity: Ayyukan lubrication na graphite ya dogara da girman flakes graphite.Girman ɓangarorin, ƙaramar ƙimar juzu'i, kuma mafi kyawun aikin lubrication.
4) Chemical kwanciyar hankali: graphite yana da kyau sinadaran kwanciyar hankali a dakin da zazzabi, kuma zai iya tsayayya da acid, alkali da Organic sauran ƙarfi lalata.
5) Plasticity: Graphite yana da kyau tauri kuma ana iya haɗa shi cikin zanen gado na bakin ciki sosai.
6) Juriya na girgiza zafi: Graphite na iya jure yanayin zafi mai tsanani ba tare da lalacewa ba lokacin amfani da zafin jiki.Lokacin da zafin jiki ya canza ba zato ba tsammani, ƙarar graphite ba ya canzawa da yawa kuma ba zai fashe ba.
1. Kamar yadda refractory kayan: graphite da kayayyakin da kaddarorin na high zafin jiki juriya da kuma high ƙarfi.A cikin masana'antar ƙarfe, galibi ana amfani da shi don yin gyare-gyaren graphite.A cikin ƙera ƙarfe, graphite galibi ana amfani da shi azaman wakili na kariya don ingots na ƙarfe da rufin tanderun ƙarfe.
2. A matsayin conductive abu: amfani a cikin lantarki masana'antu don kerarre lantarki, goge, carbon sanduna, carbon shambura, m lantarki ga mercury tabbatacce halin yanzu transformers, graphite gaskets, tarho sassa, coatings ga talabijin shambura, da dai sauransu.
3. A matsayin kayan shafawa mai juriya: Graphite galibi ana amfani dashi azaman mai mai a cikin masana'antar injina.Lubricating man sau da yawa ba za a iya amfani da karkashin high-gudun, high-zazzabi, da kuma high-matsi yanayi, yayin da graphite lalacewa-resistant kayan iya aiki ba tare da lubricating man fetur a high zamiya gudu a yanayin zafi jere daga 200 zuwa 2000 ℃.Yawancin na'urorin da ke jigilar kafofin watsa labaru masu lalata an yi su da kayan graphite don yin kofuna na piston, zoben rufewa, da bearings, waɗanda ba sa buƙatar ƙara mai mai mai yayin aiki.Emulsion graphite shima mai kyau ne don sarrafa ƙarfe da yawa (zanen waya, zanen bututu).
