Yintoni i-thermal conductivity yengubo ye-ceramic fiber?

Iingubo ze-Ceramic fiber zizinto ezithandwayo zokugquma ezaziwa ngeempawu zazo ezikhethekileyo zokufudumala. Zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa i-aerospace, ukuveliswa kwamandla, kunye nokuvelisa, ngenxa yezakhono zabo eziphezulu. Enye yezona zinto zibalulekileyo ezinegalelo ekusebenzeni kwazo kukusebenza kwazo okuphantsi kwe-thermal conductivity.

I-Thermal conductivity ngumlinganiselo wezinto eziphathekayo zokuqhuba ubushushu. Kunjengobungakanani bobushushu obuthi buqukuqele kwindawo yeyunithi yesixhobo kwiyunithi yexesha ngokomahluko wobushushu beyunithi. Ngamagama alula, i-thermal conductivity inquma ukuba izinto eziphathekayo zinokudlulisela njani amandla obushushu.

Iingubo ze-Ceramic fiber zine-conductivity ephantsi kakhulu ye-thermal, oluluphawu olunqwenelekayo lwe-insulating applications. I-conductivity ephantsi ye-thermal yezi ngubo ibangelwa ngokukodwa ukubunjwa kwesakhiwo se-ceramic fibers.

Iintsinga zeCeramic zenziwe ngokudityaniswa kwe-alumina kunye ne-silica, ene-conductivity ephantsi ye-thermal. Ezi fiber zincinci kwaye zikhaphukhaphu, kunye nomlinganiselo ophezulu, oku kuthetha ukuba ubude bazo bukhulu kakhulu kunobubanzi bazo. Esi sakhiwo sivumela umoya ongaphezulu kunye ne-voids ngaphakathi kwengubo, esebenza njengezithintelo ze-thermal kunye nokuthintela ukuhanjiswa kobushushu.

I-thermal conductivity ye-ceramic fiber blanket ingahluka ngokuxhomekeke kuhlobo oluthile kunye nokubunjwa kwengubo, kunye nobuninzi bayo. Ngokubanzi, i-thermal conductivity ye-ceramic fiber blankets isuka kwi-0.035 ukuya kwi-0.08 W / m.·K. Olu luhlu lubonisa ukuba iingubo ze-ceramic fiber zineempawu ezibalaseleyo zokugquma, njengoko zine-conductivity ephantsi kakhulu ye-thermal xa kuthelekiswa nezinye izinto eziqhelekileyo zokugquma njenge-fiberglass okanye i-rock wool.

I-thermal conductivity ephantsi yeiingubo ze-ceramic fiberinikeza iingenelo ezininzi kwizicelo. Okokuqala, inceda ukunciphisa ukulahleka kobushushu okanye ukufumana, ukuqinisekisa ukusebenza kakuhle kwamandla kwiinkqubo zoshishino kunye nezakhiwo. Ngokuthintela ukuhanjiswa kobushushu, iingubo ze-ceramic fiber zinceda ukugcina indawo ezinzileyo kunye nokulawulwa kokunciphisa amandla afunekayo ukutshisa okanye ukupholisa indawo.

Ukongeza, i-thermal conductivity ephantsi yeengubo ze-ceramic igalelo ekuxhathiseni kwabo ngokugqwesileyo kumaqondo aphezulu. Ezi ngubo ziyakwazi ukumelana namaqondo obushushu ukuya kuma-2300°F (1260°C) ngelixa begcina ingqibelelo yabo yesakhiwo kunye neempawu zokukhusela. Oku kwenza ukuba kube yinto efanelekileyo kwizicelo ezibandakanya iindawo eziphakamileyo zokushisa, ezifana ne-linings yesithando somlilo okanye i-kiln.
