Ibisobanuro ku bicuruzwa

Carbone / karubone(aha ni ukuvuga “C / C cyangwa CFC ”) ni ubwoko bwibintu byinshi bishingiye kuri karubone kandi bigashimangirwa na fibre karubone nibicuruzwa byayo (karuboni fibre preform). Ifite inertia ya karubone n'imbaraga nyinshi za fibre fibre. Ifite imiterere yubukanishi, kurwanya ubushyuhe, kurwanya ruswa, kugabanya ubukana hamwe nubushyuhe bwumuriro n amashanyarazi

CVD-SiCigifuniko gifite ibiranga imiterere imwe, ibintu byegeranye, birwanya ubushyuhe bwinshi, birwanya okiside, isuku nyinshi, aside & alkali irwanya na organic reagent, hamwe nibintu bihamye byumubiri nubumara.

Ugereranije nibikoresho bya grafite bifite isuku nyinshi, grafite itangira okiside kuri 400C, bizatera igihombo cyifu bitewe na okiside, bikaviramo kwanduza ibidukikije kubikoresho bya periferi hamwe nicyumba cya vacuum, kandi byongera umwanda wibidukikije bifite isuku nyinshi.

Nyamara, igifuniko cya SiC kirashobora kugumya gutuza kumubiri na chimique kuri dogere 1600, Irakoreshwa cyane mubikorwa bigezweho, cyane cyane munganda ziciriritse.

Isosiyete yacu itanga serivise zo gutunganya SiC hakoreshejwe uburyo 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 yibikoresho bisize, gukora urwego rwo kurinda SIC. SIC yashizweho ihujwe cyane na base ya grafite, itanga igishushanyo cyihariye cya grafite, bityo bigatuma ubuso bwa grafite bwuzuzanya, Ubusa butagira ubukana, ubushyuhe bwo hejuru, kurwanya ruswa no kurwanya okiside.

 Gutunganya ibishashara bya SiC hejuru yubushakashatsi bwa MOCVD

Ibyingenzi byingenzi:

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.
