Umuzingo wa Silicon Carbide
Udupira twa Silicon Carbide (SiC)ni byo bice by'ingenzi by'amatanura azunguruka, bikoreshwa cyane mu gucana ibumba ry'inyubako, ibikoresho by'isuku, ibumba ryo mu rugo, n'ibumba ry'ikoranabuhanga. Hashingiwe ku buryo bwo gukora, bigabanyijemo ubwoko bubiri: Reaction Bonded Silicon Carbide (RBSiC) na Recrystallized Silicon Carbide (RSiC).
Kugereranya ubwoko:
1. SiC Ihuza Ibitekerezo (RBSiC):
Imiterere: Irimo ingano nto ya silikoni y'ubuntu.
Ibyiza: Ubucucike bwinshi, imbaraga nyinshi, kandi ihendutse.
Ubushyuhe bwo hejuru: Kugeza kuri 1400°C.
Uburyo bwo kuyikoresha: Ni nziza cyane ku matafari yo mu rugo akoresha ubushyuhe buri hagati kugeza kuri buri hejuru. Itanga ingano nziza y'imikorere n'igiciro.
2. SiC yongeye gukoreshwa (RSiC):
Imiterere: Isuku cyane kandi nta gice cyo guhuza.
Ibyiza: Irwanya ubushyuhe bwinshi kandi irwanya gukurura (nta guhinduka kw'ingufu mu bushyuhe bwinshi).
Ubushyuhe bwo hejuru: Kugeza kuri 1650°C+.
Ikoreshwa: Ni nziza cyane mu gukoresha ibikoresho by'isuku n'ibikoresho byihariye bya ceramic mu bushyuhe bwinshi aho bisaba ubushyuhe bukabije.
Ibiranga by'ingenzi:
1. Ingufu zo mu bushyuhe bwinshi cyane:Igumana imiterere myiza ya mekanike nubwo haba hari ubushyuhe buri hagati ya 1400°C na 1600°C.
2. Ubudahangarwa bwiza bw'ubushyuhe:Irwanya impinduka zihuse z'ubushyuhe, ikarinda gucika cyangwa kwangirika mu gihe cy'ubushyuhe n'ubukonje bwihuse.
3. Ubudahangarwa bwinshi bwo kwambara:Yongera igihe cyo gukora kandi ikagabanya ikiguzi cyo kubungabunga mu itanura risanzwe.
4. Ubudahangarwa ku ingese no kugabanya ubushyuhe:Ikora neza mu kirere gitandukanye cy'itanura, irwanya isuri ya shimi.
5. Ubuziranenge bwo mu rwego rwo hejuru:Irangi ryoroshye rituma ibicuruzwa bya ceramic bitwarwa neza kandi neza.

Ifuru y'ibikoresho bya electrode ya Lithium ifite bateri nziza n'iy'ibinure:ikoreshwa mu gushyigikira no gutwara ibikoresho fatizo bya electrode nziza na mbi.
Ibumba ry'isuku ry'ubwubatsi, ibumba rya buri munsi, ibumba ry'ikoranabuhanga, ibikoresho bya rukuruzi:ikoreshwa mu gutwara no gushyigikira ibikoresho bya ceramic bigomba gushya.
Ibikoresho bivura ubushyuhe bw'ikirahure, birwanya kwangirika kw'ibirahure:bigira uruhare runini mu bikorwa bitandukanye byo kuvura ubushyuhe bwinshi.
Ibibazo Bikunze Kubazwa
Ukeneye ubufasha? Menya neza ko usura urubuga rwacu rw'ubufasha kugira ngo uhabwe ibisubizo by'ibibazo byawe!
Turi uruganda nyakuri, uruganda rwacu rwihariye mu gukora ibikoresho birwanya ubushyuhe mu gihe kirenga imyaka 30. Twizeza gutanga igiciro cyiza, serivisi nziza mbere yo kugurisha no nyuma yo kugurisha.
Kuri buri gikorwa cyo gukora, RBT ifite sisitemu yuzuye ya QC y’imiterere ya chimique n’imiterere ifatika. Kandi tuzagerageza ibicuruzwa, kandi icyemezo cy’ubuziranenge kizatangwa hamwe n’ibicuruzwa. Niba ufite ibisabwa byihariye, tuzagerageza uko dushoboye kose kugira ngo tubigereho.
Bitewe n'ingano, igihe cyo kohereza kiratandukanye. Ariko twizeza kohereza vuba bishoboka kandi bifite ubuziranenge bwemejwe.
Birumvikana ko dutanga ingero ku buntu.
Yego, birumvikana ko mufite ikaze gusura ikigo cya RBT n'ibicuruzwa byacu.
Nta mupaka uhari, dushobora gutanga igitekerezo cyiza n'igisubizo gikwiye bitewe n'imimerere yawe.
Tumaze imyaka irenga 30 dukora ibikoresho birwanya ubushyuhe, dufite ubufasha bukomeye mu bya tekiniki n'uburambe bwinshi, dushobora gufasha abakiriya gushushanya amatanura atandukanye no gutanga serivisi imwe.
