Waa maxay garaafka nadiifka sare leh iyo garaafka la shubay? Waxaa la rumeysan yahay in dad badan aysan ka warqabin garaafka sare ee nadiifka ah. Hadda, agaasimaha Li ee Jiuyi Seal ayaa sharxi doona waxa garaafyada saafiga ah ee sarreeya iyo waxa garaafyada la sameeyay:
Garaafyada daahirsanaanta sare, oo sidoo kale loo yaqaan graphite caaryar, waxay ka dhigan tahay in maadada kaarboon ee graphite ay ka badan tahay 99.99%, waxayna leedahay conductivity heer sare ah, iska caabin kulaylka, caabbinta oksaydhka, index resistor hoose, iska caabin daxalka, daahirsanaan sare, is saliidayn, kulaylka iska caabin shoogga, anisotropy, waxayna ku habboon tahay farsamaynta farsamada saxda ah ee saxda ah. Kalluunka miisaanka graphite daahirnimada sare leh waa mid faahfaahsan, dhuuban oo dhuuban, waxayna leeyihiin sifooyin jireed oo aad u fiican. Waa qalab cayriin ah oo bilaash ah oo kaarboon ah, oo si ballaaran loogu isticmaalo hawada, qalabka iftiinka qoraxda iyo qalabka semiconductor, duubista birta, qalabyada aluminiumka adag iyo qalabka elektarooniga ah ee caaryada, dareeraha dhaldhalaalka, muraayadaha la dhejiyay, qalabka farsamada, tamarta iyo warshadaha kale ee wax soo saarka.
Garaafyada saafiga ah ee sarreeya waxay leedahay faa'iidooyin gaar ah oo soo saarista iyo farsamaynta qaybaha kuleyliyaha korantada, abuurista dhismaha dhinta, qalabka birta nadiifka ah ee dhirta dhalaalaysa, kuleyliyaha korantada ee foornada crystal-ka ah, graphite EDM gooyay silig, sintering ayaa dhinta, tuubada hagaajinta anodizing , daahan walxaha birta ah, garaafyada tongs loogu talagalay tignoolajiyada semiconductor, diraya tuubooyinka toosiyaha, thyratron, iyo graphite anodizing iyo shabag ee ballasts meerkuri arc. Gaar ahaan, graphite-nadiifinta sare leh oo leh tilmaamo waaweyn, moodooyin iyo tayo sare leh, sida alaabta ceeriin ee beddelka ah, waxay leedahay meel bannaan oo gudaha ah oo ballaaran oo loogu talagalay isticmaalka sayniska iyo tignoolajiyada cusub, waxayna leedahay rajo codsi oo ballaaran.
Hababka nadiifinta garaafka sare ee nadiifka ah ayaa loo qaybin karaa laba qaybood: mid waa nadiifinta qoyan, oo ay ku jiraan habka dhexdhexaadka ah ee culus, aashitada xooggan iyo habka saldhigga xooggan, iyo habka hydrogen acid; Midda kale waa nadiifinta dabka, oo ay ku jiraan habka calcination isopropyl titanate iyo habka heerkulka sare.
Garaafka saafiga ah ee sarreeya, isticmaalka ugu muhiimsan ee garaafka la shubay waa:
Waxaa si weyn loo isticmaalaa in alaabta dahaarka refractory iyo daahan dhismaha birta iyo warshadaha birta, walxaha qarxa xasilinta warshadaha difaaca qaranka, qalin qalin warshadaha iftiinka, motor kaarboon buraashka warshadaha qalabka korontada, darajada korantada ee warshadaha batteriga dib loo dallaci karo, biraha ka hortagga anti -Wakiilka daxalka ee warshadaha bacriminta organic, iwm ka dib markii wax soo saarka iyo processing, graphite-nadiifinta sare sidoo kale soo saari kartaa wax soo saarka sayniska iyo teknoolajiyada cusub sida emulsion graphite, shaabadihii caag graphite iyo alaabta polymer, alaabta graphite, graphite preservatives antifriction, oo noqda furaha. alaabta ceeriin ee shirkadaha macdanta ee qayb kasta oo warshadeed.
