Ibisobanuro
Isosiyete yacu iratangaSiCserivisi zitunganijwe nuburyo bwa CVD hejuru ya grafite, ceramique nibindi bikoresho, kugirango imyuka idasanzwe irimo karubone na silikoni ikora ubushyuhe bwinshi kugirango ibone molekile nziza ya SiC, molekile zashyizwe hejuru yubutakacoatedibikoresho, bigize SIC ikingira.
Ibiranga imitwe ya SiC yo kwiyuhagira ni ibi bikurikira:
1. Kurwanya ruswa: Ibikoresho bya SiC bifite imbaraga zo kurwanya ruswa kandi birashobora kwihanganira isuri y’amazi atandukanye y’imiti n’ibisubizo, kandi birakwiriye mu gutunganya imiti itandukanye no gutunganya ibintu.
2. Ubushyuhe bwo hejuru:SiC nozzlesIrashobora kugumya gutuza muburyo bwubushyuhe bwo hejuru kandi irakwiriye kubisabwa bisaba kuvura ubushyuhe bwinshi.
3. Gutera icyarimwe:SiC nozzleIgishushanyo gifite imikorere myiza yo gutera imiti, ishobora kugera kumasoko amwe kandi ikemeza ko amazi yo kuvura atwikiriye neza hejuru yintego.
4. Kurwanya kwambara cyane: Ibikoresho bya SiC bifite ubukana bwinshi kandi birwanya kwambara kandi birashobora kwihanganira gukoresha igihe kirekire no guterana amagambo.
Imitwe ya SiC ikoreshwa cyane muburyo bwo gutunganya amazi munganda zikora igice, gutunganya imiti, gutwikira hejuru, amashanyarazi hamwe nizindi nganda. Irashobora gutanga ingaruka zihamye, zimwe kandi zizewe zo gutera kugirango zizere neza kandi zihamye zo gutunganya no kuvura.
Ibyingenzi
1. Kurwanya ubushyuhe bukabije bwa okiside:
kurwanya okiside biracyari byiza cyane mugihe ubushyuhe buri hejuru ya 1600 C.
2. Isuku ryinshi: bikozwe nubumara bwa chimique munsi yubushyuhe bwo hejuru bwa chlorine.
3. Kurwanya isuri: gukomera kwinshi, hejuru yuzuye, ibice byiza.
4. Kurwanya ruswa: aside, alkali, umunyu na reagent.
