Nadiifin sare oo la fidin karo Graphite 300-400 jeer
budada garaafka
Barta karkarinta: 4250 ℃
Darajada cufan: 1.6 ~ 2.2
Waa in la isticmaalo: carburizer, dhalaalid
Qaab dhismeedka: heerkulka sare u adkaysta, conductive, conductivity kulaylka
Budada Graphite waxaa loo qaybin karaa laba qaybood oo waaweyn:
1. Garaafyada dabiiciga ah
2. garaafka synthetic
Waxaa ka mid ah, graphite dabiiciga ah wuxuu leeyahay noocyada soo socda:
1. Garaafka caleen
2. Garaafyada spheroidal
3. Garaafyada yar yar
4. Garaafka la fidin karo
5. Garaafyada ciidda
Garaafyada caleen
waa garaafiye crystalline ah oo dabiici ah, kaas oo la mid ah fosfooraska kalluunka oo ka tirsan nidaamka crystalline-ka.Waxay leedahay qaab-dhismeed lakabaysan.Waxay leedahay sifooyin wanaagsan oo iska caabbinta heerkulka sare, korantada, kuleylka kulaylka, saliidaynta, caagagga iyo caabbinta acid-saldhigga.
Garaafyada Flake waa saliid dabiici ah oo leh qaab dhismeed, qani ku ah kheyraadka iyo qiimo jaban.
Garaafyada dabiiciga ah
waxaa la sameeyay by isbedelka of carbon-hodan organic walxaha hoos ficil muddada-dheer ee heerkulka sare iyo deegaanka juqraafi cadaadis sare, iyo waa crystallization ee dabiiciga ah.Tilmaamaha tignoolajiyada ee garaafyada dabiiciga ah waxay inta badan ku xiran yihiin qaabkeeda crystalline.Macdanta leh foomamka crystalline kala duwan waxay leeyihiin qiimaha warshadaha kala duwan iyo isticmaalka.Waxaa jira noocyo badan oo graphite dabiiciga ah.Marka loo eego qaab-dhismeedka crystalline kala duwan, garaafyada dabiiciga ah waxaa loo qaybiyaa garaafyada crystalline cufan, graphite flake iyo graphite cryptocrystalline.
