Izingubo zokulala zefayiji ye-ceramic ziyizinto ezithandwayo zokufakelwa ezaziwa ngempahla yazo ehlukile ye-thermal. Zisetshenziswa kabanzi emikhakheni ehlukahlukene, kufaka phakathi i-aerospace, amandla kagesi, kanye nokwenza, ngenxa yamakhono abo aphezulu. Enye yezinto ezibalulekile ezifaka isandla ekusebenzeni kwazo ngokuvuka kwabo okuphansi okushisayo.
Ukusebenza okushisayo kuyisilinganiso sekhono lezinto ezibonakalayo zokwenza ukushisa. Kunjengenani lokushisa eligeleza endaweni yeyunithi yezinto ezibonakalayo kwiyunithi yesikhathi ngasinye sokushisa samayunithi. Ngemigomo elula, ukuqina okushisayo kunquma ukuthi okubonakalayo kungadlulisa kahle kangakanani ukudlulisa amandla okushisa.
Izingubo zokulala ze-ceramic fiber zinokuphamba okuphansi kakhulu okushisayo, okuyisici esifunekayo sokufaka izicelo. Ukuvuselelwa okuphansi kwalezi zingubo zokulala kuvame ukubangelwa ukwakheka kwesakhiwo okuyingqayizivele kwemicu ye-ceramic.
Imicu ye-Ceramic yenziwa ngokuhlanganiswa kwezinto ze-alumina kanye ne-silica, ezinokwenza ngcono okushisayo okushisayo. Le micu imncane futhi ingasindi, inesilinganiso esiphakeme, okusho ukuthi ubude bawo bukhulu kakhulu kunobubanzi babo. Lesi sakhiwo sivumela umoya owengeziwe kanye nama-voids ngaphakathi kwengubo, esenza njengezithiyo ezishisayo futhi ziphazamise ukudluliswa kokushisa.
Ukuvuselelwa okushisayo kwe-ceramic fiber blanket kungahluka ngokuya ngohlobo oluthile nokwakheka kwengubo, kanye nobuningi baso. Ngokuvamile, ukuthuthuka okushisayo kwezingubo zokulala ze-ceramic fiber kusuka ku-10.035 kuya ku-0.08 w / m·UK. Leli hlahla libonisa ukuthi izingubo zokulala ze-ceramic fiber zinezakhiwo ezinhle kakhulu zokufakelwa, njengoba zinabantu abanokuvuka okushisayo okuphansi kuqhathaniswa nezinye izinto ezijwayelekile zokufakwa njenge-fiberglass noma uboya be-fiberglass noma uboya be-fiberglass noma uboya be-rock.
Ukuvuselelwa okuphansi okushisayo kweIzingubo zokulala ze-Ceramic fiberInikeza izinzuzo eziningana kuzinhlelo zokusebenza. Okokuqala, kuyasiza ukunciphisa ukulahleka kokushisa noma ukuzuza, ukuqinisekisa ukusebenza kahle kwamandla ezinhlelweni zezimboni nasezakhiweni. Ngokuvimbela ukudluliselwa kokushisa, izingubo zokulala ze-ceramic fiber zisiza ukugcina imvelo ezinzile nelawulwa ukunciphisa amandla adingekayo ukushisa noma ukupholisa isikhala.
Ngokwengeziwe, ukuthuthuka okuphansi okushisayo kwezingubo zokulala ze-ceramic kunomthelela ekumelaneni kwazo okuhle kakhulu kumazinga okushisa aphezulu. Lezi zingubo zingamelana namazinga okushisa aze afike ku-2300°F (1260°C) ngenkathi egcina ubuqotho babo bokuhleleka kanye nokufaka izakhiwo. Lokhu kwenza okuhle kakhulu kwezicelo ezibandakanya izindawo ezishisa kakhulu, njengezinsimbi zomlilo noma i-kiln.
