Ceramic fibers, aluminium silicate fibers, thiab alumina fibers zoo sib xws. Ntau tus neeg hauv kev lag luam hauv mullite fiber ntau rab koob punched pam tsuas yog nkag siab txog cov khoom lawv tsim, yog li lawv tsis' tsis paub qhov txawv thiab qhov sib txawv ntawm lawv.
Ceramic fiber yog lub npe dav ntawm alumina fiber thiab aluminium silicate fiber. Vim hais tias nws yog ib yam ntawm cov ntaub ntawv ceramic tsis muaj high-alumina fiber ntau cov ntaub ntawv uas tsis yog hlau, nws yog hu ua ceramic fiber. Ob qho txhuas silicate thiab alumina yog cov khoom siv aluminium-silicon refractory, thiab tsuas yog cov ntsiab lus ntawm AL2O3 thiab cov ntsiab lus ntawm cov khoom tseem ceeb theem muaj pes tsawg leeg ntawm alumina fiber yog hu ua txawv. Lub ntsiab siv lead ua theem yog aluminium silicate (cov ntsiab lus ntawm AL2O3 yog li 30-69%), uas yog hu ua aluminium silicate fiber. Cov fiber ntau uas nws lub ntsiab siv lead ua yog alumina (al2O3 cov ntsiab lus saum 90%) yog hu ua alumina fiber. Cov fibers no tau ua rau hauv cov paj rwb zoo li cov fibers los ntawm kev txau thiab spinning tom qab cov khoom ntxhia hauv cov khoom tawg tau yaj. Cov paj rwb zoo li no tuaj yeem ua rau hauv cov ntaub pua plag ceramic los ntawm rab koob punching, thiab tuaj yeem ua rau hauv cov ntawv fiber ntau ceramic, ceramic fiber board, thiab lwm yam los ntawm kev ntxiv cov neeg sawv cev sib txuas kom ntub dej thiab ziab. Los ntawm qhov pom ntawm qhov kub thiab txias, qhov kub tsis kam ntawm aluminium silicate fiber ntau yog 1260 ~ 1450 ℃, thiab qhov kub tsis kam ntawm alumina fiber yog 1700 ℃ ~ 1800 ℃. Txawm li cas los xij, los ntawm kev lag luam tam sim no ntawm kev pom, daim ntawv thov ntau yam ntawm aluminium silicate fiber ntau yog qhov siab. Feem ntau cov kev lag luam yuav tsis tshaj qhov kub ntawm 1500 degrees, qhov thib ob yog tus nqi siab ntawm polycrystalline mullite thiab alumina fiber ntau, thiab qhov thib peb yog vim tsis paub tab technology, cov khoom sib xws ntawm polycrystalline mullite thiab alumina fiber ntau tsawg, thiab nws yog tsis txaus siab. Daim ntawv thov yuav tsum tau, yog li cov khoom siv aluminium silicate fiber ntau yog siv rau qhov chaw ua haujlwm tam sim no.
