Mullite
Mullite,tseem hu ua mullite, yog ib tug series ntawm cov zaub mov muaj li ntawm aluminosilicate collectively, thiab mullite kuj yog ib tug ntxhia lub npe, uas yog ib tug mineral generated los ntawm aluminosilicate ntawm kub. Nws tau pom thawj zaug ntawm cov kob ntawm Mull, tawm ntawm ntug dej hiav txwv sab hnub poob ntawm Scotland.
Qhov ceev ntawm lub teeb yuag mullite cib muaj qhov cuam tshuam rau ntau lwm yam khoom, xws li porosity, lub zog, yaig tsis kam, load softening kub, hnav tsis kam thiab thermal shock resistance. Qhov ntom ntawm lub teeb yuag mullite cib kuj tseem cuam tshuam nrog nws cov thermal conductivity thiab tshav kub muaj peev xwm.
Cov khoom tseem ceeb ntawm corundum mullite cib yog alumina, cov ntaub ntawv tseem ceeb yog purity corundum thiab mullite, thiab alumina refractory cib yog tsim los ntawm corundum thiabmullitelub ntsiab siv lead ua theem. Corundum - mullite cib hais txog kev ua siab dawb huv lossis cov ntaub ntawv ntshiab uas ua los ntawm cov khoom siv refractory.
Corundum cib thiab mullite cib yog cov khoom siv qib siab hauv cov ntaub ntawv refractory, thiab tseem yog cov alumina series. Nyob rau hauv sib piv, corundum bricks muaj ib tug me me expansion coefficient tshaj mullite cib. Corundum cib muaj cov ntsiab lus siab melting, ruaj khov kub ua haujlwm thiab zoo hnav tsis kam. Mullite cib zoo ib yam li high alumina firebricks. Muaj ob hom ntawm mullite, ib qho yog mullite ua rau kub kub los ntawm clinker nrog cov ntsiab lus siab aluminium, thiab lwm yam yog mullite cib ua los ntawm mullite ntxiv tom qab molding thiab firing ntawm kub.
Muaj ntau ntau hom refractory bricks, thiab expansion coefficient yog txawv. Piv nrog corundum cib thiab mullite cib, qhov nthuav dav ntawm corundum cib yog me dua li ntawm mullite.
Polycrystallinemullitefiberboard tseem hu ua ceramic fiber, uas belongs rau fiber ntau refractory. Nws yog ib yam tshiab ntawm cov khoom, thiab muaj qhov zoo ntawm thermal stability, me me kub yaj, thermal expansion me me, thiab lwm yam. Nws yog siv nyob rau hauv ntau yam teb.
