Ikabati rya Ceramic Fiber: Imiterere myiza n'Ibisobanuro Bisanzwe byo Gushyiramo Ubwugarizi mu Nganda

Mu rwego rwo gukingira ubushyuhe bwinshi mu nganda,igitambaro cy'ubudodo bwa ceramicIgaragara nk'igisubizo gihendutse kandi gifite imikorere myiza, gikoreshwa cyane mu byuma, peteroli, ingufu z'amashanyarazi, n'izindi nganda. Yakozwe mu bikoresho bya alumina-silica bifite isuku nyinshi binyuze mu kuzunguruka cyangwa gushyushya kandi igaterwa inshinge mu buryo bwa mekanike nta bifunga, ihuza uburyo bwiza bwo kurwanya ubushyuhe, ubworoherane, no kuramba, bigatuma iba ibikoresho by'ingenzi mu bisubizo bigezweho byo gucunga ubushyuhe.

Imiterere itangaje y'igitambaro cya fibre cya ceramic ni yo mpamvu ituma gikundwa cyane. Mbere na mbere, gifite ubushobozi bwo guhangana n'ubushyuhe bwinshi, aho ubushyuhe buri hagati ya 1100℃ na 1600℃ (2012℉ kugeza 2912℉) bitewe n'urwego, hamwe n'ubushyuhe buhoraho bugera kuri 1350℃ ku buryo bworoshye, bigatuma imikorere ihoraho ndetse no mu bushyuhe bukabije. Ubushyuhe bwayo buri hasi cyane (bugera kuri 0.09 W/MK kuri 400℃) bugabanya ubushyuhe, bunoza imikorere myiza y'ingufu kandi bugabanya ikoreshwa rya lisansi ho 20-40% mu nganda.

Iyo myambaro yoroheje kandi yoroshye kuyikoresha, ni 70% byoroheje ugereranyije n’ibikoresho bisanzwe byo kuyishyiraho, bigatuma kuyishyiraho byoroha—ndetse no ku miterere ikomeye nk'inkuta z'itanura, imiyoboro, n'aho kuyishyira byoroshye. Ifite ubushobozi bwo kurwanya ubushyuhe bwinshi, ifite imiyoboro iri munsi ya 3% ku bushyuhe bwinshi bwo kuyikoresha, yirinda kwangirika kw'ubushyuhe bwihuse. Byongeye kandi, nta kintu kiyihambiraho, ntishobora gushya, kandi ifite ubushobozi bwo kudacika intege, irwanya ibintu byinshi byangiza (usibye alkali zikomeye na aside hydrofluoric) kandi irinda ko imyuka isohoka mu gihe cyo kuyikoresha, ibyo bikaba byongera umutekano no kubungabunga ibidukikije. Itanga kandi imikorere yo kwinjiza amajwi no kugabanya urusaku, irushaho kunoza ibidukikije byo gukoreramo.

Kugira ngo ihuze n'ibikenewe bitandukanye mu nganda, igitambaro cya fibre cya ceramic kiza mu buryo busanzwe hamwe n'uburyo bworoshye bwo guhindura. Ku bijyanye n'ubucucike, amahitamo asanzwe ni 96, 128, na 160 kg/m³ (6-10 lb/ft³), hamwe n'ibipimo bimwe na bimwe biboneka kuri 64 kg/m³ ku bikenerwa byoroheje, kuringaniza imikorere y'ubushyuhe n'ubushobozi bwo gupima. Ubunini buri hagati ya mm 6 na mm 50 (santimetero 0.25-2), aho igitambaro gito cya mm 6-10 gikwiriye ahantu hato, igitambaro cya mm 20-25 gipima imikorere n'ingano, naho igitambaro cya mm 50 gitanga ubushobozi bwo kubika ubushyuhe bwinshi mu bihe by'ubushyuhe bwinshi cyane.

Ku bijyanye n'ingano, imigozi isanzwe ifite uburebure bwa mm 7200/3600, ubugari bwa mm 610/1220, kandi ishobora guhindurwa kugeza kuri mm 16000 n'ubugari bwa mm 1830 bitewe n'ibyo umushinga ukeneye. Mu rwego rwa shimi, ibice by'ingenzi ni alumina (Al₂O₃) na silica (SiO₂), hamwe n'ingano rusange ya 96-99% ku byiciro byinshi; amanota arimo zirconium yongeraho 5-17% ZrO₂ kugira ngo yongere ubushyuhe buhamye, Al₂O₃+SiO₂+ZrO₂ igera kuri 99%. Ingufu zo gukurura ni 0.04-0.12 MPa (ubucucike bwa 128kg/m³), bigatuma imiterere y'inyubako ikomera mu gihe cyo kuyishyiraho no kuyikoresha.

Byaba ari iby'ifuru, ubushyuhe bw'amatanura, uburinzi bw'imiyoboro, cyangwa ibifunga bidashya, ubushyuhe bw'amatanura butanga umusaruro wizewe, buzigama ingufu, kandi bumara igihe kirekire. Imiterere yabwo inyuranye hamwe n'imiterere yabwo ihinduka ituma buba amahitamo ya mbere yo kubushyushya mu bushyuhe bwinshi mu nganda. Hitamo ubushyuhe bwacu bw'amatanura kugira ngo wongere uburyo bwawe bwo gucunga ubushyuhe, ugabanye ikiguzi cy'imikorere, kandi ugere ku iterambere rirambye.
