Emkhakheni wokushisa okuphezulu kwezimboni,ingubo yefayibha yobumbaIvelele njengesixazululo esingabizi kakhulu nesisebenza kahle, esisetshenziswa kabanzi kwezensimbi, amakhemikhali kaphethroli, ukukhiqizwa kwamandla, kanye neminye imboni. Yenziwe ngezinto ze-alumina-silica ezihlanzekile kakhulu ngezinqubo zokuphotha noma zokuvunguza futhi ifakwa ngenaliti ngomshini ngaphandle kwezihlanganisi, ihlanganisa ukumelana okuhle kakhulu nokushisa, ukuguquguquka, kanye nokuqina, okwenza kube yinto ebalulekile yezixazululo zanamuhla zokuphathwa kokushisa.
Izakhiwo ezivelele zengubo yefayibha ye-ceramic ziyisihluthulelo sokuthandwa kwayo kabanzi. Okokuqala nokubaluleke kakhulu, inezinga lokushisa eliphakeme kakhulu, enamazinga okushisa asukela ku-1100℃ kuya ku-1600℃ (2012℉ kuya ku-2912℉) kuye ngebanga, kanye namazinga okushisa asebenzayo aqhubekayo afinyelela ku-1350℃ ezinhlotsheni eziphezulu, okuqinisekisa ukusebenza okuzinzile ngisho nasezindaweni ezishisa kakhulu. Ukushisa kwayo okuphansi kakhulu (okuphansi njengo-0.09 W/MK ku-400℃) kunciphisa ngempumelelo ukulahleka kokushisa, kuthuthukisa ukusebenza kahle kwamandla futhi kunciphise ukusetshenziswa kukaphethiloli ngo-20-40% ezisetshenziswa ezimbonini.
Ilula futhi iguquguquka, ingubo ilula ngo-70% kunezingqimba zendabuko zokungaguquguquki, okwenza ukufakwa kube lula—ngisho nasezimo eziyinkimbinkimbi njengezindonga zesithando somlilo, amapayipi, kanye namajoyinti okunwebeka. Ibonisa ukumelana okuhle kakhulu kokushaqeka kokushisa, ngokuncishiswa okuqondile okungaphansi kuka-3% emazingeni okushisa aphezulu okusebenza, igwema umonakalo obangelwa ukushintshashintsha kwezinga lokushisa okusheshayo. Ngaphezu kwalokho, ayinazo izimbobo, ayishi, futhi izinzile kahle ngamakhemikhali, imelana nezinto eziningi ezigqwalisayo (ngaphandle kwama-alkali aqinile kanye ne-hydrofluoric acid) futhi iqinisekisa ukuthi akukho ugesi ophumayo ngesikhathi sokusetshenziswa, okuthuthukisa ukuphepha kanye nobungane bemvelo. Iphinde inikeze imisebenzi yokumunca umsindo kanye nokunciphisa umsindo, okwenza ngcono indawo yokusebenza.
Ukuze kuhlangatshezwane nezidingo zezimboni ezahlukahlukene, ingubo yefayibha ye-ceramic iza ngezincazelo ezijwayelekile ezinezinketho zokwenza ngokwezifiso eziguquguqukayo. Ngokuphathelene nobuningi, izinketho ezivamile zingama-96, 128, kanye no-160 kg/m³ (6-10 lb/ft³), kanti amanye amazinga atholakala ku-64 kg/m³ ngezidingo ezilula, ukulinganisa ukusebenza kokushisa kanye nokusebenza kahle kwesisindo. Ubukhulu busukela ku-6mm kuya ku-50mm (0.25-2 amayintshi), lapho izingubo zokulala ezincane ezingu-6-10mm zifanelana nezikhala ezixineneyo, ezingu-20-25mm zilinganisa ukusebenza kanye nomthamo, kanti ezingu-50mm zinikeza ukugcinwa kokushisa okuphezulu kakhulu ezimweni zokushisa okuphezulu kakhulu.
Ngokuphathelene nobukhulu, imiqulu ejwayelekile ingu-7200/3600mm ubude, ububanzi bungu-610/1220mm, futhi ingenziwa ngokwezifiso kufikela ku-16000mm ubude kanye nobubanzi obungu-1830mm ngokwezidingo zephrojekthi. Ngokwekhemikhali, izingxenye eziyinhloko yi-alumina (Al₂O₃) kanye ne-silica (SiO₂), enokuqukethwe okuphelele okungu-96-99% kwamamaki amaningi; amamaki aqukethe i-zirconium anezela u-5-17% ZrO₂ ukuthuthukisa ukuzinza kokushisa okuphezulu, kanye ne-Al₂O₃+SiO₂+ZrO₂ efinyelela ku-99%. Amandla okudonsa angu-0.04-0.12 MPa (ubuningi obungu-128kg/m³), okuqinisekisa ubuqotho besakhiwo ngesikhathi sokufakwa nokusetshenziswa.
Kungakhathaliseki ukuthi kungeze-furnace linings, i-boiler insulation, i-pipe protection, noma i-fire seals, i-ceramic fiber blanket inikeza ukusebenza okuthembekile, ukonga amandla, kanye nokuphila isikhathi eside. Izakhiwo zayo eziguquguqukayo kanye nemininingwane engenziwa ngokwezifiso kwenza kube ukukhetha kokuqala kwe-high-temperature yokushisa kuzo zonke izimboni. Khetha i-ceramic fiber blanket yethu ukuze uthuthukise uhlelo lwakho lokuphatha ukushisa, unciphise izindleko zokusebenza, futhi ufeze intuthuko esimeme.
