Isesengura ryimbitse ry'ihame ryo gushyushya inkoni ya grafiti

Inkoni ya grafiti ikunze gukoreshwa nk'igikoreshoicyuma gishyushya amashanyarazi cy'itanura rishyushya cyane. Biroroshye kuyisiga ku bushyuhe bwinshi. Uretse isuku y'umwuka, ishobora gukoreshwa gusa mu kirere kitagira aho gihuriye cyangwa mu kirere gigabanya ubushyuhe. Ifite ingano nto y'ubushyuhe, ubushobozi buhanitse bwo gutwara ubushyuhe, ubushobozi buhanitse bwo kurwanya ubushyuhe bwinshi, ubushobozi buhanitse bwo kurwanya ubukonje bukabije n'ubushyuhe bukabije, hamwe n'igiciro gito. Igipimo cya oxidation n'igipimo cyo guhinduka kwa grafiti bigira ingaruka ku buzima bw'umukoresha w'ubushyuhe. Iyo umwanya nyawo ari 10-3 ~ 10-4 mmHg, ubushyuhe bwa serivisi bugomba kuba munsi ya 2300 ℃. Mu kirere kirinda (H2, N2, AR, nibindi), ubushyuhe bwa serivisi bushobora kugera kuri 3000 ℃. Grafiti ntishobora gukoreshwa mu kirere, bitabaye ibyo izasukwamo oxidation ikayinywa. Igira ingaruka zikomeye kuri W hejuru ya 1400 ℃ kugira ngo ikore carbides.
Inkoni ya grafiti igizwe ahanini na grafiti, bityo dushobora no gusobanukirwaimiterere ya grafiti:
Aho graphite ishongera ni henshi cyane. Itangira koroha kandi ikunda gushonga iyo igeze kuri 3000C munsi y'umwuka. Kuri 3600C, graphite itangira gushonga no gushonga. Ingufu z'ibikoresho rusange zigabanuka buhoro buhoro iyo ubushyuhe buri hejuru. Ariko, iyo graphite ishyushye kugeza kuri 2000C, imbaraga zayo ziba inshuro ebyiri iyo ubushyuhe buri mu cyumba. Ariko, ubushobozi bwo kudashonga bwa graphite buragabanuka cyane, kandi igipimo cyo kudashonga kiriyongera buhoro buhoro uko ubushyuhe bwiyongera.
Ubushobozi bwo gutwara ubushyuhe bwa grafiti n'ubushobozi bwo gutwara ubushyuhe buri hejuru cyane. Ubushobozi bwo gutwara ubushyuhe bwa grafiti buri hejuru inshuro 4 ugereranije n'ubw'icyuma kitagira umugese, inshuro 2 ugereranije n'ubw'icyuma cya karuboni n'inshuro 100 ugereranije n'ubw'icyuma gisanzwe kitari icyuma. Ubushobozi bwo gutwara ubushyuhe bwayo ntiburuta gusa ubw'ibikoresho by'icyuma nk'icyuma, icyuma n'icyuma, ahubwo bunagabanuka uko ubushyuhe bwiyongera, bitandukanye n'ubw'ibikoresho by'icyuma rusange. Grafiti ikunda kuba adiabatic ku bushyuhe buri hejuru cyane. Kubwibyo, imikorere yo gukingira ubushyuhe bwa grafiti ni yizewe cyane mu gihe cy'ubushyuhe bwinshi cyane.
Amaherezo, dushobora kwemeza ko ihame ryo gushyushyainkoni ya grafitini: uko umuyoboro w'amashanyarazi wongerwa ku nkoni ya grafiti uba mwinshi, niko ubushyuhe bw'ubuso bw'inkoni ya grafiti burushaho kwiyongera.
