Uburyo bwo gukumira flake grafite kuba oxyde ku bushyuhe bwinshi

Kugirango wirinde kwangirika kwangirika guterwa na okiside ya grake ya flake ku bushyuhe bwinshi, birakenewe ko dushakisha ibikoresho byo gushyira ikote hejuru yubushyuhe bwo hejuru, bushobora kurinda neza grake ya flake okiside ku bushyuhe bwinshi. Kugirango tubone ubwoko bwa flake grafite anti-okiside, tugomba mbere na mbere kurwanya ubushyuhe bwo hejuru no guhuzagurika.
Kurwanya ruswa nziza, irwanya okiside ikomeye, ubukana bwinshi nibindi biranga. Furuite Graphite Xiaobian ikurikira irerekana uburyo bwo kwirinda flake grafite kuba okiside mubushyuhe bwinshi:

1. Koresha ibikoresho bifite umuvuduko wumuyaga uri munsi ya 0.1333MPa (1650 * C) nibikorwa byiza byuzuye.
2. Hitamo ibirahuri by'ibirahure byujuje ibyangombwa bisabwa nkibikoresho byo kwifungisha, hanyuma ube ibikoresho bifunga kashe ku bushyuhe bwakazi.
3. Ukurikije imikorere yingufu zisanzwe zubusa ziterwa na ogisijeni hamwe nubushyuhe, mubushyuhe bwo gukora ibyuma (1650-1750 * C), ibikoresho byatoranijwe cyane na ogisijeni kuruta karubone-ogisijeni byatoranijwe kugirango bifate ogisijeni, bityo nka okiside ubwabo no kurinda flake grafite. Nyuma ya okiside, hashyizweho icyiciro gishya hamwe nubunini bwikigereranyo cyumwimerere.
Kinini, gifasha guhagarika umuyoboro wimbere wa ogisijeni no gukora inzitizi ya okiside.
4. Ku bushyuhe bwakazi, umubare munini wibintu nka Al2O3, SiO2 na Fe2O3 mubyuma bishongeshejwe birashobora kwamamazwa, bikabyitwaramo ubwabyo, kuburyo ibintu bitandukanye biva mubyuma byashongeshejwe byinjira buhoro buhoro.
Ubushyuhe bwa okiside ya flake grafite ikorerwa mu Bushinwa ni 560815 ° C mugihe ibirimo karubone ari 88% 96% naho ubunini bwacyo bukaba burenga 400. Muri byo, iyo ingano yubunini bwa grafite ari 0.0970.105mm, ubushyuhe bwa okiside ya grafite ifite ibice birenga 90% bya karubone ni 600815 ° C naho karubone iri munsi ya 90%.
Ubushyuhe bwa okiside ya wino ni 620790 C. Nibyiza ko grafitike ya kristaline nziza, niko ubushyuhe bwo hejuru bwa okiside iba, kandi kugabanuka kwa okiside ntigabanutse ku bushyuhe bwinshi.
