Mu gawo la kutchinjiriza mafakitale kutentha kwambiri,bulangeti la ceramic fiberImadziwika ngati njira yotsika mtengo komanso yogwira ntchito bwino, yomwe imagwiritsidwa ntchito kwambiri mu zitsulo, petrochemicals, kupanga magetsi, ndi mafakitale ena. Yopangidwa kuchokera ku zinthu zoyera kwambiri za alumina-silica kudzera mu njira zozungulira kapena kupukutira ndipo imapangidwa ndi makina popanda zomangira, imagwirizanitsa kukana kutentha, kusinthasintha, komanso kulimba, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri pa njira zamakono zoyendetsera kutentha.
Kapangidwe kake ka nsalu ya ceramic fiber ndi chinsinsi cha kutchuka kwake. Choyamba, imakhala ndi kukana kutentha kwambiri, kutentha kwa magulu kuyambira 1100℃ mpaka 1600℃ (2012℉ mpaka 2912℉) kutengera mtundu wake, komanso kutentha kosalekeza mpaka 1350℃ kwa mitundu yapamwamba, kuonetsetsa kuti ikugwira ntchito bwino ngakhale m'malo otentha kwambiri. Kutentha kwake kochepa kwambiri (kotsika mpaka 0.09 W/MK pa 400℃) kumachepetsa kutaya kutentha, kupititsa patsogolo kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa kugwiritsa ntchito mafuta ndi 20-40% m'mafakitale.
Chopepuka komanso chosinthasintha, bulangeti ndi lopepuka ndi 70% kuposa zinthu zachikhalidwe zosinthira, zomwe zimapangitsa kuti kuyika kwake kukhale kosavuta—ngakhale pa mawonekedwe ovuta monga makoma a uvuni, mapaipi, ndi malo olumikizirana. Lili ndi mphamvu yabwino kwambiri yolimbana ndi kutentha, ndipo limachepa ndi 3% pa kutentha kwakukulu kogwiritsa ntchito, kupewa kuwonongeka chifukwa cha kusinthasintha kwa kutentha mwachangu. Kuphatikiza apo, silimasunga ma binder, siliyaka, ndipo lili ndi kukhazikika kwabwino kwa mankhwala, limalimbana ndi zinthu zambiri zowononga (kupatula alkalis amphamvu ndi hydrofluoric acid) ndipo limaonetsetsa kuti mpweya sutuluka panthawi yogwiritsa ntchito, zomwe zimapangitsa kuti chitetezo komanso chilengedwe chikhale bwino. Limaperekanso ntchito zoyamwa mawu komanso kuchepetsa phokoso, zomwe zimapangitsa kuti malo ogwirira ntchito azigwira ntchito bwino.
Kuti zikwaniritse zosowa zosiyanasiyana zamafakitale, bulangeti la ulusi wa ceramic limabwera m'njira zokhazikika komanso zosintha zosinthika. Ponena za kuchulukana, zosankha zodziwika bwino ndi 96, 128, ndi 160 kg/m³ (6-10 lb/ft³), ndipo mitundu ina imapezeka pa 64 kg/m³ pazofunikira zopepuka, kulinganiza magwiridwe antchito a insulation ndi kulemera bwino. Kukhuthala kwake kumayambira pa 6mm mpaka 50mm (0.25-2 mainchesi), pomwe bulangeti lopyapyala la 6-10mm limagwirizana ndi malo opapatiza, bulangeti la 20-25mm limalinganiza magwiridwe antchito ndi voliyumu, ndipo bulangeti la 50mm limapereka kutentha kokwanira pazochitika zotentha kwambiri.
Ponena za miyeso, mipukutu yokhazikika ndi 7200/3600mm m'litali, 610/1220mm m'lifupi, ndipo ikhoza kusinthidwa mpaka 16000mm m'litali ndi 1830mm m'lifupi malinga ndi zosowa za polojekiti. Mwa mankhwala, zigawo zazikulu ndi alumina (Al₂O₃) ndi silica (SiO₂), zokhala ndi kuchuluka kwa 96-99% pamitundu yambiri; mitundu yokhala ndi zirconium imawonjezera 5-17% ZrO₂ kuti iwonjezere kukhazikika kwa kutentha, ndi Al₂O₃+SiO₂+ZrO₂ kufika 99%. Mphamvu yokoka ndi 0.04-0.12 MPa (kuchuluka kwa 128kg/m³), kuonetsetsa kuti kapangidwe kake ndi kolimba panthawi yoyika ndi kugwiritsa ntchito.
Kaya ndi zophimba ng'anjo, zotchingira boiler, zoteteza mapaipi, kapena zomatira zosayaka moto, bulangeti la ulusi wa ceramic limapereka magwiridwe antchito odalirika, kusunga mphamvu, komanso moyo wautali. Kapangidwe kake kosiyanasiyana komanso mawonekedwe ake osinthika zimapangitsa kuti ikhale chisankho choyamba cha zotchingira kutentha kwambiri m'mafakitale osiyanasiyana. Sankhani bulangeti lathu la ulusi wa ceramic kuti muwongolere makina anu oyendetsera kutentha, kuchepetsa ndalama zogwirira ntchito, ndikukwaniritsa chitukuko chokhazikika.
