Njira yopewera 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 malaya pa kutentha zakuthupi, amene angathe kuteteza flake graphite kuti makutidwe ndi okosijeni pa kutentha kwambiri. Kuti tipeze malaya amtundu wa flake graphite anti-oxidation, choyamba tiyenera kukana kutentha kwambiri komanso kusakanikirana.
Zabwino, kukana kwa dzimbiri, kukana mwamphamvu kwa okosijeni, kuuma kwakukulu ndi mawonekedwe ena. Zotsatirazi za Furuite Graphite Xiaobian zikuyambitsa njira zopewera flake graphite kukhala oxidized pa kutentha kwambiri:

1. Gwiritsani ntchito zida zokhala ndi mphamvu ya nthunzi zosakwana 0.1333MPa (1650 * C) komanso magwiridwe antchito abwino.
2. Sankhani zinthu zamagalasi zomwe zimakwaniritsa zofunikira pakugwirira ntchito ngati chinthu chodzisindikizira, ndikupangitsa kukhala chinthu chosindikizira ming'alu pa kutentha kogwira ntchito.
3. Malinga ndi ntchito ya mphamvu yaulere ya zomwe zimachitika ndi okosijeni ndi kutentha, pa kutentha kwazitsulo (1650-1750 * C), zipangizo zomwe zimakhala zogwirizana kwambiri ndi mpweya kuposa mpweya wa carbon-oxygen zimasankhidwa kuti zitenge mpweya wabwino. monga oxidize okha ndi kuteteza flake graphite. Pambuyo pa okosijeni, gawo latsopano lokhala ndi chiŵerengero cha voliyumu ya gawo loyambirira limapangidwa.
Chachikulu, chomwe chimathandiza kutsekereza njira yamkati ya oxygen ndikupanga chotchinga cha okosijeni.
4. Pa kutentha kwa ntchito, chiwerengero chachikulu cha inclusions monga Al2O3, SiO2 ndi Fe2O3 muzitsulo zosungunula zimatha kugulitsidwa, zomwe zimadzichitira okha ku sinter, kotero kuti inclusions zosiyanasiyana kuchokera kuzitsulo zosungunuka pang'onopang'ono zilowe mu zokutira.
Kutentha kwa makutidwe ndi okosijeni wa flake graphite opangidwa ku China ndi 560815 ° C pomwe mpweya wa carbon ndi 88% 96% ndipo kukula kwa tinthu kumaposa ma meshes 400. Pakati pawo, pamene tinthu kukula kwa graphite ndi 0.0970.105mm, makutidwe ndi okosijeni kutentha graphite ndi oposa 90% mpweya zili 600815 ° C ndi mpweya zili zosakwana 90%.
The makutidwe ndi okosijeni kutentha inki ndi 620790 C. bwino crystalline flake graphite ndi, ndi apamwamba makutidwe ndi okosijeni pachimake kutentha ndi, ndipo zochepa makutidwe ndi okosijeni kuwonda ndi pa kutentha kwambiri.
