Sifooyinka graphite-ka

Sifooyinka graphite-ka

1. Xasillooni kiimiko oo wanaagsan
Graphite waa walax kiimiko ahaan deggan, xasilloonideeda kiimikadana kama hooseyso tan biraha qaaliga ah. Milankeeda lacagta dhalaalaysa waa 0.001% – 0.002%.Garaafitkuma milmo dareere dabiici ah ama kuwa aan organic ahayn. Ma milaan oo ma milmo inta badan asiidhyada, saldhigyada iyo cusbooyinka.
2. Iska caabin heerkul sare ah oo ku saabsan dhalista graphite
Iyada oo loo marayo tijaabooyin, heerkulka adeegga ee biinanka heerka kaarboonka guud wuxuu gaari karaa 350 ℃; Biinanka garaafka birta ah sidoo kale waa 350 ℃; Biinanka heerka garaafka elektaroonigga ah wuxuu gaari karaa 450-500 ℃ (culays fudud), sifooyinkiisa jireed iyo farsamo ahaan isma beddelin, heerkulkiisa adeegguna wuxuu gaari karaa 1000 ℃ jawi faakiyuum ama ilaalin ah.
3. Waxqabad wanaagsan oo is-salibid ah
Dhalista garaafkaWaxay leedahay waxqabad is-saliideyn oo wanaagsan laba sababood awgood. Mid ka mid ah sababaha ayaa ah in atamka kaarboon ee ku jira shabagga garaafka lagu habeeyay diyaarad kasta qaab lix-geesood ah oo caadi ah. Masaafada u dhaxaysa atamka waa mid isku dhow, taas oo ah 0.142 nm, halka masaafada u dhaxaysa diyaaraduhu ay tahay 0.335 nm, waxayna isku leexleexan yihiin jihada isku midka ah. Diyaaradda saddexaad waxay ku celisaa booska diyaaradda koowaad, diyaaradda afraad waxay ku celisaa booska diyaaradda labaad, iwm. Diyaarad kasta, xoogga isku xidhka ee u dhexeeya atamka kaarboonku aad buu u xoog badan yahay, halka masaafada u dhaxaysa diyaaraduhu ay weyn tahay, xoogga van der Waals ee u dhexeeyana aad buu u daciif yahay, sidaa darteed way fududahay in laga tago oo la dhex maro lakabyada, waana sababta aasaasiga ah ee ay walxaha garaafka u leeyihiin sifooyin is-saliideyn ah.
Sababta labaad ayaa ah in walxaha garaafitku ay leeyihiin dhegdheg xooggan oo ay la socdaan inta badan walxaha birta ah, sidaa darteed garaafitka la jarjaray si fudud ayuu ugu dhegi karaa dusha sare ee birta marka uu ku shiido birta, taasoo sameysanaysa lakabfilim garaafit ah, kaas oo noqda is jiidjiidka u dhexeeya graphite iyo graphite, taasoo si weyn u yareynaysa xirashada iyo isku-dhafka is jiidjiidka, Tani sidoo kale waa mid ka mid ah sababaha ay biinanka graphite-ka kaarboonku u leeyihiin waxqabad is-saliidayn oo heer sare ah iyo waxqabad ka hortagga is jiidjiidka.
4. Sifooyinka kale ee graphite-ka
Marka la barbar dhigo noocyada kale ee bearings,biirta garaafkasidoo kale waxay leeyihiin koronto-qaadis heer sare ah, isku-darka hoose ee ballaarinta toosan, qaboojinta degdega ah iyo iska caabbinta kulaylka iwm.
