Intangiriro ya grafite yoroheje yunvikana
Ubushyuhe bwo hejuru grafite yunvikana ifite imiterere yuburemere bworoshye, guhungabana neza, karuboni nyinshi,ubushyuhe bwo hejuru, nta guhindagurika ku bushyuhe bwo hejuru,Kurwanya ruswa, gitoubushyuhe bwumurirono kugumana imiterere yo hejuru.
Igicuruzwa gifite ibyiza bikurikira: nyuma ya 1800 ~ 2500 treatment kuvura ubushyuhe bwo hejuru, itandukaniro ryubushyuhe hagati yingingo ebyiri zose zunvikana ntirurenze 50 ℃, bityo imikorere yibicuruzwa irahagaze. Kuberako ari umusaruro uhoraho, irashobora kwemeza uburinganire bwibintu byunvikana mubugari n'uburebure.
Ugereranije nakaruboneivurwa ku bushyuhe buke (munsi ya 900 ℃), grafite yumvise ivuwe ku bushyuhe bwo hejuru (hejuru ya 2200 ℃) ifite ibyiza bikurikira:
) Kubikoresho byinshi bifunze ibikoresho bigomba gukenerwa, ubuziranenge bwikirere nibintu byingenzi. Nyamara, kubera adsorption nyinshi yubushyuhe buke bwavuwe na karubone, biragoye guhumeka ubwato.
(2) Igishushanyo cyunvikana gifite imbaraga zo kurwanya ubushyuhe bwa okiside. Imiterere ya karubone idafite igishushanyo ni ubwoko bwimiterere idahwitse. Kuba hariho inenge zitandukanye zubatswe bituma intera yacyo iba nini, kandi biroroshye kwibasirwa na atome ya ogisijeni na okiside. Uruzitiro rwiza kandi rwategetse gutondekanya ibice bitatu bya grafite nyuma yo kuvura ubushyuhe bwinshi bigabanya cyane intera igaragara kandi bigatuma bitoroha kwibasirwa na atome ya ogisijeni, bityo bikazamura cyane ubushobozi bwa antioxydeant.
(3) Isuku ya grafite yunvikana ni ndende, kandi karubone irenga 99.5%. Carbone yubushyuhe buke bwavuwe na karubone yumva muri rusange iri munsi ya 93%, byoroshye guteza umwanda ibidukikije mumatanura.
Mw'ijambo, ubushyuhe bwo hejuru bwavuwe na grafite yunvise ifite ingaruka nziza nubuzima bwa serivisi burenze ubushyuhe buke bwa karubone.
