Waxay ku habboon tahay biyaha kulul, heerkulka sare, uumiga cadaadiska sare, dareeraha isweydaarsiga kulaylka, nitrogen, dareeraha organic, hydrocarbon, dareeraha heerkulka hooseeya iyo warbaahinta kale.Cadaadiska (Mpa): 25 Heerkulka(℃):-200~850 Xawaaraha toosan (m/s): Qiimaha 30PH: 0~14 giraangiraha garaafka waxa loo qaybiyaa garaafiga dabacsan iyo giraanta kaarboon-graphite.Kaarboon-graphite siddooyinkooda waxaa inta badan loo isticmaalaa in lagu xidho qaybaha wareegta farsamada oo waxay leeyihiin sifooyin caabbinta daxalka.
1. Giraanta garaafka ayaa leh is-saliid wanaagsan.
2. Soo celinta sare ee giraanta garaafka.
3. Giraanta garaafyada waxaa lagu gooyn karaa gooyn 45° oblique ah iyadoo loo eegayo baahida isticmaale.
1.Select kulul-sare qalabka tuurista madal qalab rakibo ee tilmaamayaasha u dhiganta;
2.ku rakib saxanka qaybinta, sleeve, saxan adabtarada, jeexdin qaybinta, iyo giraanta graphite-ka sare ee nadiifka ah ee dhinaca sare ee madal, oo ku rakib gacanta, saxanka adabtarada, iyo giraanta garaafka ee caaryada.
Gudaha, hubi inay nadiif yihiin, wax dhaawac ah iyo dalool la'aan.Way fiicantahay in la isticmaalo xaashida dhoobada dhoobada ah ama bustaha dhoobada dhoobada ah si loo xiro dhinacyada iyo hoose, taas oo waxtar u leh kuleylka kuleylka.
3.After guud ahaan kulul top madal shubidda lagu rakibay, si siman preheat madal qalabka caadiga ah rakiban in 260-350 ℃, by koronto ama gaaska.Olol furan waa inuusan la xiriirin xuubka dahaarka ee alaabta, Haddii kale, burburka dildilaaca dhaca waxaa qaadi doona isticmaaluhu.
4.ka saar biyaha kiristaalka ah, ka dhig mid badbaado leh oo waxtar leh
