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 kugira ibintu bimwe na bimwe nko kurwanya ubushyuhe bwinshi, guhuza neza, imikorere myiza yo kurwanya ruswa, ubushobozi bukomeye bwo kurwanya okiside hamwe nubukomere bukabije. Abanditsi ba Furuite bakurikira basangiye uburyo bwo gukumiraflake grafitekuva okiside ku bushyuhe bwinshi:

1. Koresha ibikoresho bifite umuvuduko uri munsi ya 0.1333MPa (1650 ℃) nibintu 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 ℃), ibikoresho byatoranijwe cyane na ogisijeni kuruta karubone-ogisijeni byatoranijwe gufata mbere ya ogisijeni, bityo Kuri okiside ubwabo no kurinda uflake grafite. Ingano yicyiciro gishya cyakozwe nyuma ya okiside nini kuruta iyicyiciro cyambere, ifasha guhagarika umuyoboro wogukwirakwiza imbere 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.

Grafite ya Furuite iratwibutsa ko ubushyuhe bwa okiside ya flake grafite mu bice bikuru by’Ubushinwa bitanga umusaruro ni 560815 ℃ iyo karubone ari 88% 96% naho ingano y’ibice iri hejuru ya -400 mesh. Muri byo, iyo ingano yubunini bwa grafite ari 0.0970.105mm, ubushyuhe bwa okiside ya grafite ifite ibice birenga 90% bya karubone ni 600815 ℃ naho ibya grafite bitarimo 90% bya karubone ni 62075 ℃. Kurenzaflake grafiteni, hejuru ya oxydeire yubushyuhe buri hejuru, kandi kugabanuka kwa okiside kurwego rwo hejuru ni.
