Ibumba rya karubide rya silikoniIfite uruhare runini mu bikorwa by’amatanura mu nganda mu nzego nyinshi. Ikoreshwa ry’ibanze ni imiyoboro y’ubushyuhe bwa silicon carbide, ikoreshwa cyane mu buryo bwo gutwika bushyuha cyane mu gutunganya ibyuma, gukora ibirahuri, no gucana ceramic bitewe n’uko imiterere yabyo ihamye mu bidukikije bishyuha cyane. Indi mikoreshereze y’ingenzi ni silicon carbide rollers, ikora nk’inkunga no gutwara ibice mu matanura ahoraho, cyane cyane mu gutwika ceramics zigezweho, ibikoresho by’ikoranabuhanga, n’ibirahuri by’ubuziranenge. Byongeye kandi, SiC ceramics zikoreshwa nk’ibice by’imiterere nk’imiringa, imiringoti, n’ibice bishyiraho ibikoresho mu matanura, aho zimara igihe kirekire zihura n’ikirere gikaze n’imbaraga za mekanike. Kwinjizwa kwazo mu bikoresho bihindura ubushyuhe kugira ngo zigarure ubushyuhe bw’imyanda birushaho kugaragaza ubuhanga bwazo mu gucunga ubushyuhe bujyanye n’amatanura. Izi mikoreshereze zigaragaza ubushobozi bwa silicon carbide bwo guhangana n’ibikenewe bitandukanye mu mikorere mu ikoranabuhanga rishyuha mu nganda.
Ibikorwa by'ingenzi byo gukoresha mu itanura ry'inganda birimo:
1.Ingunguru z'icyuma gitwika karubide ya silikoni
3.Imitako ya karubide ya silikoni
4.Umuyoboro w'imirasire ya silicon carbide
Ibyiza bya tekiniki
1. Ubushyuhe budasanzwe buhamye
- Aho gushonga: 2,730°C (bikomeza ibidukikije bishyushye cyane)
- Ubudahangarwa bw'umwuka kugeza kuri 1,600°C mu kirere (burinda kwangirika mu kirere cya oxidative)
2. Uburyo bwo gutwara ubushyuhe buhanitse cyane
- 150 W/(m·K) ubushyuhe butwara ubushyuhe mu bushyuhe bw'icyumba (butuma ubushyuhe bwihuta bukwirakwira kandi bugakwirakwira mu buryo bumwe)
- Bigabanya ikoreshwa ry'ingufu ho 20–30% ugereranije n'ibikoresho gakondo birwanya ubushyuhe.
3. Ubudahangarwa bw'ingufu z'ubushyuhe butagereranywa
- Ihangana n'ihindagurika ryihuse ry'ubushyuhe rirenze 500°C/sec (ni byiza cyane mu gihe cyo gushyushya/gukonjesha).
- Ibungabunga imiterere y'inyubako mu gihe cy'ubushyuhe (irinda kwangirika no guhinduka).
4. Ingufu nyinshi za mekanike ku bushyuhe buri hejuru
- Igumana 90% by'ubushyuhe bw'icyumba kuri 1,400°C (ingenzi ku bikoresho by'itanura ritwara imizigo).
- Ubukana bwa Mohs bwa 9.5 (burwanya kwangirika kw'ibikoresho byo mu itanura).
| Umutungo | Karubide ya silikoni (SiC) | Alumina (Al₂O₃) | Ibyuma bihindura umwuka (urugero, aloyi zishingiye kuri Ni) | Ibintu gakondo byo gushyushya (urugero: amatafari yo mu muriro) |
| Ubushyuhe ntarengwa | Kugeza kuri 1600°C+ | 1500°C | 1200°C (yoroshya hejuru) | 1400–1600°C (biratandukanye) |
| Ubushobozi bwo gutwara ubushyuhe | Hejuru (120–200 W/m·K) | Hasi (~30 W/m·K) | Iringaniye (~15–50 W/m·K) | Hasi cyane (<2 W/m·K) |
| Ubudahangarwa bw'ihungabana ry'ubushyuhe | Nibyiza cyane | Bike cyane kugeza ku biri hagati | Iringaniye (ubushobozi bwo gukora ibintu neza burafasha) | Biteye ubwoba (icikagurika munsi ya ΔT yihuta) |
| Imbaraga za mekanike | Igumana imbaraga mu bushyuhe bwinshi | Igabanuka hejuru ya 1200°C | Igabanuka iyo ubushyuhe buri hejuru | Hasi (ifite imyenge, ifite utwenge) |
| Ubudahangarwa bw'inkongi | Irwanya aside, alkali, ibyuma bishongeshejwe/ibisigazwa | Iciriritse (iterwa na aside/base zikomeye) | Ishobora kwibasirwa n'ubushyuhe bwinshi mu gihe cy'izuba ryinshi | Bigabanuka mu kirere kirimo kwangirika |
| Igihe cy'ubuzima | Ndende (irinda kwangirika/okisidasiyo) | Ingano iri hagati (imyanya iri hagati y'ubushyuhe) | Ngufi (ituma umuntu ahumeka/agenda yihuta) | Igihe gito (gutumba, isuri) |
| Gukoresha neza ingufu | Gutwara ubushyuhe bwinshi (byihuta) | Ubushyuhe buke (ubushyuhe buke) | Iringaniye (ikora ariko igabanya ogisijeni) | Hafi cyane (irinda ubushyuhe) |
Urubanza rw'inganda
Ikigo gikomeye mu gutunganya ibyuma cyageze ku ntera ikomeye mu mikorere nyuma yo gushyiramo silicon carbide (SiC) ceramics mu bikoresho byayo bishyuha cyane. Binyuze mu gusimbuza ibice bisanzwe bya alumina naimiyoboro y'icyuma gitwika karubide ya silikoni, ikigo cyatanze raporo igira iti:
✅ Amafaranga yo kubungabunga buri mwaka yagabanutseho 40% bitewe no kugabanuka kwangirika kw'ibice mu bidukikije bishyushye cyane mu gihe cy'ubushyuhe bwa 1500°C+.
✅ Kwiyongera kwa 20% mu gihe cyo gukora, bitewe n'uko SiC irwanya ubushyuhe n'ingese biturutse ku ishwagara ryashongeshejwe.
✅ Guhuza n'amahame ngenderwaho ya ISO 50001 agenga imicungire y'ingufu, hakoreshejwe uburyo bwa SiC bwo gutwara ubushyuhe bwinshi kugira ngo hakorwe neza lisansi ku kigero cya 15–20%.
