Mullite hluav taws cib Yog qhov tseem ceeb siab - kub refractory cov khoom siv nyob rau hauv ntau cov khoom siv kub-} cov khoom siv qeeb.
Nws thawj cov khoom sib xyaw yog alumina (al₂o₃) thiab silica (sio₂), nrog al₂o₃ cov ntsiab lus feem ntau xws li 60% rau 75%, nyob ntawm qib tshwj xeeb. Mullite muaju tsim cov txheej txheem tseem ceeb, kev ua kom zoo nkauj (fe₂₂}

Cov yam ntxwv ua tau zoo
Vim yog lawv cov qauv tshwj xeeb thiab muaj pes tsawg leeg thiab muaj pes tsawg leeg, Refractory Cib ua kom pom cov khoom lag luam zoo tshaj plaws hauv qab no:
Siab - kub kev ua tau zoo: 1840 degree), nyob ntev li 1790 3}}}} kub siv.
Excellent Thermal Shock Resistance: Due to mullite's low thermal expansion coefficient (4.5–5.5×10⁻⁶/°C), it can withstand rapid thermal cycling (typically >20 mus txog, dej quenching los ntawm 1100 degree).
Zoo heev tiv taus acidic thiab alkaline slag thiab roj corrosion, tshwj xeeb tshaj yog siv tau hauv lub iav melting rauv. Nyob hauv oxidizing thiab neutral atmetes, tab sis yuav tsum tau ceev faj hauv kev txo cov cua sov.
High Txhua Yam Zog: Tswj lub zog siab ua kom muaj zog ntawm cov chaw kub (chav sov {- kub compressive zog: 80-100 mpa).
Zoo hnav tsis kam, haum rau muaj cov neeg muaj kev ntxhov siab kho tshuab.
Tsawg thermal conductivity: thermal conductivity yog tus kuj tsawg (1.5-}} · k), muab cov txiaj ntsig zoo ntawm lub zog.
Ntim Ruaj Ntseg: Cov ntim tsawg kawg hloov ntawm cov kub, nrog cov cav ua tau zoo, ua kom ntev}}} lub sij hawm ruaj khov yam tsis muaj deformation.
Cov ntawv thov MAIN
Vim yog lawv cov khoom zoo heev, Mullite Cib yog dav siv nyob rau hauv cov nram no siab - kub muaj kev lag luam:
Kev lag luam iav: siv hauv khob Melting rauv phab ntsa, hauv qab, cov phab ntsa kub thiab cov kab mob kub, rau ntawm cov kab ntau lawm thiab borosilicate iav kilns.
Ceramic kev ua lag luam: ua haujlwm hauv ceramic firing Kils phab ntsa, thiab sigger txhawb nqa, nrog kev kub siab thiab nquag thermal shocks.
Kev lag luam hlau: siv nyob rau hauv cov khoom siv hluav taws xob sib tsoo thiab hauv qab, cua sov cov duab dhos, cua sov cov duab dhos, ua kom sov cov khoom siv, tawm tsam cov khoom kub thiab cov kab mob slag.
Tsis - Txoj Kev Lag Luam Hlau: Tooj Liab Smelting Furnaces, Zinc Distillation Rauv
Petrochemical Kev Lag Luam: catalytic cracking units, hloov chaw rhuab, tawg nthe rwg rauv
