Iyini i-thermal conductivity yengubo ye-ceramic fiber?

Izingubo zokulala ze-Ceramic fiber ziyizinto ezithandwayo zokufaka izinto ezishisayo ezaziwa ngezakhiwo zazo ezishisayo ezingavamile. Asetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi i-aerospace, ukukhiqiza ugesi, nokukhiqiza, ngenxa yamakhono azo aphezulu. Esinye sezici ezibalulekile ezifaka isandla ekusebenzeni kwazo ukwehla kwe-thermal conductivity.

I-Thermal conductivity isilinganiso sekhono lempahla lokuqhuba ukushisa. Kufana nenani lokushisa eligeleza endaweni yeyunithi yento kuyunithi yesikhathi ngomehluko weyunithi ngayinye yezinga lokushisa. Ngamagama alula, i-thermal conductivity inquma ukuthi impahla ingadlulisa kahle kangakanani amandla okushisa.

Izingubo zokulala ze-Ceramic fiber zine-conductivity ephansi kakhulu ye-thermal, okuyisici esifiselekayo sezinhlelo zokusebenza zokuvikela. I-thermal conductivity ephansi yalezi zingubo ngokuyinhloko ibangelwa ukwakheka kwesakhiwo esiyingqayizivele semicu ye-ceramic.

Imicu ye-Ceramic yenziwe ngenhlanganisela yezinto ze-alumina ne-silica, ezinokushisa okuphansi ngokwemvelo. Le micu mincane futhi ilula, inenani eliphakeme, okusho ukuthi ubude bayo bukhulu kakhulu kunobubanzi bayo. Lesi sakhiwo sivumela umoya owengeziwe kanye nama-voids ngaphakathi kwengubo, esebenza njengezithiyo ezishisayo futhi ivimbele ukudluliswa kokushisa.

I-thermal conductivity ye-ceramic fiber blanket ingahluka kuye ngokuthi uhlobo oluthile kanye nokwakheka kwengubo, kanye nokuminyana kwayo. Ngokuvamile, ukushisa okushisayo kwezingubo zokulala ze-ceramic fiber kusuka ku-0.035 kuye ku-0.08 W/m·K. Lobu bubanzi bubonisa ukuthi izingubo zokulala ze-ceramic fibre zinezakhiwo ezinhle kakhulu zokugqumisa, njengoba zine-thermal conductivity ephansi kakhulu uma kuqhathaniswa nezinye izinto ezivamile zokugqumisa njenge-fiberglass noma i-rock wool.

I-conductivity ephansi ye-thermalizingubo ze-ceramic fiberinikeza izinzuzo ezimbalwa ezinhlelweni zokusebenza. Okokuqala, kusiza ukunciphisa ukulahlekelwa ukushisa noma ukuzuza, ukuqinisekisa ukusebenza kahle kwamandla ezinqubweni zezimboni nezakhiwo. Ngokuvimbela ukudluliswa kokushisa, izingubo zokulala ze-ceramic fiber zisiza ukugcina indawo ezinzile futhi elawulwayo kunciphisa amandla adingekayo ukushisa noma ukupholisa isikhala.

Ukwengeza, i-thermal conductivity ephansi yezingubo zokulala ze-ceramic kunomthelela ekuphikiseni kwabo okuhle kakhulu emazingeni okushisa aphezulu. Lezi zingubo zokulala ziyakwazi ukumelana namazinga okushisa afinyelela ku-2300°F (1260°C) ngenkathi begcina ubuqotho besakhiwo kanye nezakhiwo zokuvikela. Lokhu kwenza kube okufanelekile ezinhlelweni ezibandakanya izindawo ezishisa kakhulu, ezifana namalayini omlilo noma iziko.
