Graphite waa allotrope of carbon, crystal ku meelgaar ah oo u dhexeeya kiristaalo atomiga, kiristaalo biraha ah iyo kiristaalo molecular Guud ahaan cawl madow, qaab jilicsan, dareen dufan leh Kulaylka sii kordhay ee hawada ama oksijiin gubta oo soo saara kaarboon laba ogsaydh. Aashito dabiici ah.Waxa loo adeegsadaa wakiilka ka hortagga dharka iyo walxaha saliidaynta, samaynta weelka, korontada, batteriga qalalan, qalin qalin qalinka. emulsion graphite, graphite la ballaadhiyay, garaafka dhoobada iyo budada garaafyada tabinta, iwm.
1. caabbinta heerkulka sare: barta dhalaalka ee garaafka waa 3850 ± 50 ℃, xitaa ka dib gubashada arc heerkulka aadka u sarreeya, miisaanka oo yaraada aad buu u yar yahay, isugeynta ballaarinta kuleylka aad ayuu u yar yahay. . 2000 ℃, xoogga garaafku wuu labanlaabmaa.
2. conductive, conductivity thermal: conductivity of graphite is a boqol times above the general non-metallic conductivity thermal of steel, iron, lead iyo qalabka kale ee birta ah. heerkulka sare, garaafka galay dahaarka;
3. lubricity: waxqabadka saliidaynta garaafku waxay ku xiran tahay xajmiga jajabka garaafka, jajabka, isku -dheelitirka khilaafku wuu yar yahay, waxqabadka sifaynta ayaa ka fiican;
4. xasiloonida kiimikada: garaafka heerkulka qolka wuxuu leeyahay xasillooni kiimiko oo wanaagsan, iska caabbinta aashitada, iska caabin alkali iyo iska caabinta daxalka dareeraha;
5. balaastigga: adkaanshaha garaafku waa wanaagsan yahay, waxaa lagu jajabin karaa xaashi aad u khafiif ah;
6. iska -caabbinta shoogga kulaylka: garaafka heerkulka qolka marka la isticmaalo wuxuu u adkaysan karaa isbeddelada ba'an ee heerkulka iyada oo aan waxyeello lahayn, isku -beddelidda heerkulka, mugga garaafku wax yar iskama beddelo, ma dillaaci doono.
1. Falanqaynta halabuurka: kaarboon go'an, qoyaan, nijaas, iwm;
2. Tijaabinta waxqabadka jirka: adayga, dambas, isku dheelitirnaanta, wanaagga, cabbirka walxaha, isbeddellada, cufnaanta gaarka ah, aagga dusha gaarka ah, barta dhalaalka, iwm.
3. tijaabinta guryaha farsamooyinka: xoogga gilgilashada, jilicsanaanta, tijaabinta foorarsiga, tijaabada cilladda;
4. tijaabinta waxqabadka kiimikada: iska caabbinta biyaha, adkeysiga, aashitada iyo iska caabin alkali, iska caabinta daxalka, iska caabinta cimilada, u adkaysiga kulaylka, iwm
5. Waxyaabaha kale ee imtixaanka: tabinta korontada, tabinta kuleylka, saliidaynta, xasilloonida kiimikada, iska caabbinta shoogga kulaylka
