Mayendedwe angapo akuluakulu a chitukuko cha graphite yowonjezereka

Graphite yokulirapo ndi chinthu chofanana ndi nyongolotsi chomasuka komanso choboola chomwe chimapangidwa kuchokera ku graphite flakes kudzera mu njira zolumikizirana, kutsuka m'madzi, kuumitsa ndi kukulitsa kutentha kwambiri. Graphite yokulirapo imatha kukula nthawi yomweyo nthawi 150 ~ 300 mu voliyumu ikakumana ndi kutentha kwakukulu, kusintha kuchokera ku flake kupita ku nyongolotsi, kotero kuti kapangidwe kake kamakhala kosasunthika, koboola komanso kopindika, malo a pamwamba amakulitsidwa, mphamvu ya pamwamba imawonjezeka, ndipo mphamvu ya adsorption ya graphite yoboola imakulitsidwa, zomwe zimawonjezera kufewa kwake, kulimba mtima komanso kusinthasintha. Mkonzi wotsatira wa Furuite graphite adzakufotokozerani njira zingapo zazikulu zopangira graphite yokulirapo:
1. Graphite yokulirapo ya granular: Graphite yaying'ono yokulirapo ya granular makamaka imatanthauza graphite yokulirapo ya maukonde 300, ndipo kukula kwake ndi 100ml/g. Chogulitsachi chimagwiritsidwa ntchito makamaka popanga zokutira zoletsa moto, ndipo chikufunika chake n'chachikulu kwambiri.
2. Graphite yofutukuka yokhala ndi kutentha kwakukulu koyambirira: kutentha koyambirira kofutukuka ndi 290-300 ° C, ndipo kuchuluka kofutukuka ndi ≥ 230 ml/g. Mtundu uwu wa graphite yofutukuka umagwiritsidwa ntchito makamaka pa choletsa moto cha pulasitiki ndi rabala zaukadaulo.
3. Kutentha kochepa koyambira kokulitsa ndi kutentha kochepa kokulitsa graphite: kutentha komwe mtundu uwu wa graphite wokulitsa umayamba kukula ndi 80-150°C, ndipo kuchuluka kokulitsa kumafika 250ml/g pa 600°C.
Opanga graphite okulirapo amatha kusakaniza graphite yokulirapo kukhala graphite yosinthasintha kuti igwiritsidwe ntchito ngati zinthu zotsekera. Poyerekeza ndi zinthu zotsekera zachikhalidwe, graphite yosinthasintha imakhala ndi kutentha kwakukulu, ndipo ingagwiritsidwe ntchito mumlengalenga pamtunda wa -200℃-450℃, ndipo ili ndi coefficient yaying'ono yokulitsa kutentha. Yagwiritsidwa ntchito kwambiri mu petrochemical, makina, zitsulo, mphamvu ya atomiki ndi mafakitale ena.
