Momwe mungapewere kuti flake graphite isakhale oxidized pa kutentha kwakukulu

Pofuna kupewa dzimbiri kuwonongeka chifukwa makutidwe ndi okosijeni wa flake graphite pa kutentha, m`pofunika kupeza zinthu kuvala mkulu-kutentha zakuthupi amene angathe kuteteza flake graphite kuti makutidwe ndi okosijeni pa kutentha. Kuti tipeze masikelo amtundu wa graphite odana ndi okosijeni, choyamba tiyenera kukhala ndi mikhalidwe ina monga kukana kutentha kwambiri, kukhazikika bwino, magwiridwe antchito abwino odana ndi dzimbiri, luso lamphamvu la anti-oxidation komanso kuuma kwakukulu. Mkonzi wotsatira wa Furuite Graphite amagawana njira yopewera flake graphite kuti ikhale oxidized pa kutentha kwakukulu:

nkhani

1. Zida zokhala ndi mphamvu ya nthunzi zosakwana 0.1333MPa (1650 ℃) ndi zinthu zabwino zonse zimatengera.

2. Sankhani gawo la galasi lomwe limakwaniritsa zofunikira pakuchita ngati chinthu chodzisindikizira, ndikupangitsa kukhala chinthu chosindikizira mng'alu mkati mwa kutentha kogwira ntchito.

3. Malinga ndi kusintha kwa mphamvu yaulere yochitira ndi mpweya ndi kutentha, pa kutentha kwazitsulo (1650-1750 ℃), sankhani zipangizo zomwe zimakhala zogwirizana kwambiri ndi mpweya kuposa mpweya wa carbon-oxygen, gwirani mpweya woyamba, ndikudzipangira okha kuti muteteze. chithunzi cha graphite. Voliyumu ya gawo latsopano lomwe limapangidwa pambuyo pa okosijeni ndi lalikulu kuposa la gawo loyambirira, lomwe limathandiza kutsekereza njira yamkati ya oxygen ndikupanga chotchinga cha okosijeni.

4. Pa kutentha kwa ntchito, imatha kuyamwa ma inclusions ambiri monga AL2O3, SiO2, Fe2O3 muzitsulo zosungunula, ndikuchitapo kanthu kuti sinter, kotero kuti ma inclusions osiyanasiyana kuchokera kuzitsulo zosungunuka pang'onopang'ono alowe mu zokutira.

Furuite Graphite Xiaobian akukumbutsa kuti kutentha kwa okosijeni wa flake graphite m'madera opangira China ndi 560,815 ℃ pamene mpweya wa carbon ndi 88% 96% ndipo kukula kwa tinthu kuli pamwamba -400 mesh. Pakati pawo, pamene tinthu kukula kwa graphite ndi 0.0970.105mm, makutidwe ndi okosijeni kutentha graphite ndi oposa 90% mpweya zili 600,815 ℃, ndi graphite ndi zosakwana 90% mpweya zili 6200 ℃. Kuchuluka kwa crystalline flake graphite kumapangitsa kuti kutentha kwa oxidation kukhale kokwera komanso kumachepetsa kuchepa kwa thupi pa kutentha kwakukulu.
