Njira yopewera glake graphite kuti ikhale oxidized pa kutentha kwambiri

Pofuna kupewa kuwonongeka kwa kuwonongeka komwe kumachitika chifukwa cha ma okoma a flake kutentha kwambiri, ndikofunikira kupeza chinthu kuti muike chofunda kutentha kwambiri, komwe kumatha kuteteza grake grakur pa kutentha kwambiri. Kuti tipeze chovala chamtundu wamtunduwu chojambula cha Flake-oxida, tiyenera kukhala ndi mawonekedwe ena monga kutentha kwambiri, kuphatikiza koyenera, kugwiritsa ntchito mphamvu yabwino, kuthekera kwamphamvu kwa oxidation. Otsatsa otsatirawa a Fuute graphite amagawana njira zopeweraFlake graphiteKuyambira oxidized pa kutentha kwambiri:

1. Gwiritsani ntchito zida zamitundu yochepera 0.1333MPA (1650 ℃) komanso zinthu zabwino zokwanira.

2. Sankhani gawo lagalasi lomwe limakwaniritsa zofunikira za magwiridwe antchito ngati zinthu zodzipangira nokha, ndikupangitsa kuti ikhale nkhani yolimbana ndi kutentha kwanyengo.

3. Malinga ndi ntchito ya muyezo wazomwe zimachitika ndi mpweya ndi mpweya, pa kutentha kwapakatikati (1650-1750 ℃), mapangidwe omwe ali ndi oxygen woyamba, kuti atembenukeFlake graphite. Kuchuluka kwa gawo latsopanoli pambuyo poti makuti oxidation ndi okulirapo kuposa gawo loyambirira, lomwe limathandiza kuletsa njira yolerera ya oxygen ndikupanga chotchinga cha oxidation.

4. Pamatenthedwe ogwirira ntchito, ophatikizika ambiri monga Alyo3, Sio2, Sha2o3 mu chitsulo chosungunula amatha kukhala odzitchinjiriza, omwe amadzikakamiza kukhala ochimwa pang'ono pang'onopang'ono amalowa.

Furdiite graphite akutikumbutsa kuti kutentha kwa mafuta a flake graphite ku China kopanga ndi 560815 ℃ pomwe kukula kwa mpweya ndi 88% ma mesh. Pakati pawo, kukula kwa tinthu ta graphite ndi 0,0970.105mm, kutentha kwa ma fodya ndi 600% ℃ ndi wa graphite wokhala ndi 90% ℃. CrystallineFlake graphiteNdiye kuti, kutentha kwambiri kwa oxidation ndi, ndipo pang'ono kuchepa kwa thupi la oxidation.
