Nrog rau txoj kev loj hlob sai ntawm industrialization, qhov kev thov rau cov ntaub ntawv refractory nyob rau hauv txhua qhov chaw ntawm lub neej tseem loj hlob.Refractory mullite rwb thaiv tsev cib, raws li hom tshiab ntawm siab -kub- cov khoom tiv thaiv refractory, muaj nws cov yam ntxwv tshwj xeeb. Cov yam ntxwv tseem ceeb ntawm refractory mullite rwb thaiv tsev cib yog qhia hauv qab no:
1. Muaj zog siab -kub stability: Mullite rwb thaiv tsev cib tau dhau los ua qhov tshwj xeeb siab- kev kho kub kom muaj kev ruaj ntseg ntawm qhov kub thiab txias thiab yuav tsis poob lawv cov rwb thaiv tsev vim qhov kub ntawm - ib puag ncig kub.
2. Zoo thermal rwb thaiv tsev kev ua tau zoo: Mullite rwb thaiv tsev bricks muaj zoo thermal rwb thaiv tsev kev ua tau zoo. Nws cov qauv microporous tshwj xeeb tso cai rau nws kom txo tau cov cua sov kom zoo thiab ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab txo qis emission.
Kev tiv thaiv hluav taws zoo: refractory Mullite rwb thaiv tsev cib yog ib qho inorganic non-cov khoom siv hlau uas tsis yog-combustible thiab resistant rau kub kub. Nws muaj kev tiv thaiv hluav taws zoo thiab tuaj yeem tiv thaiv kev nyab xeeb ntawm lub tsev.
4. Lub neej ua haujlwm ntev: Mullite rwb thaiv tsev bricks muaj lub neej ua haujlwm ntev thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig sab nraud. Nyob rau tib lub sijhawm, lawv lub neej kev pabcuam ntev dua li cov khoom siv rwb thaiv tsev zoo tib yam, uas tuaj yeem txuag tau tus nqi ntawm kev tu thiab hloov tom qab.
5. Yooj yim rau txheej txheem: refractory mullite rwb thaiv tsev cib muaj kev ua haujlwm zoo, yooj yim rau kev txiav thiab nruab, tuaj yeem txiav thiab ua tiav raws li qhov xav tau tiag tiag, thiab tib lub sijhawm yooj yim rau nruab thiab txhim kho, uas pab txhawb kev txhim kho kev loj hlob.
Feem ntau, raws li qhov siab -kub- cov khoom siv tiv thaiv refractory, refractory mullite rwb thaiv tsev cib muaj qhov tshwj xeeb zoo thiab cov yam ntxwv. Nyob rau hauv lub neej yav tom ntej txoj kev loj hlob, mullite rwb thaiv tsev bricks yuav siv dav nyob rau hauv ntau yam teb, muab kev txhawb zog rau txoj kev loj hlob ntawm tag nrho cov mus rau lub neej. Peb tau cog lus los muab peb cov neeg siv khoom zoo tshaj plaws mullite rwb thaiv tsev cib thiab lwm yam khoom siv refractory. Yog tias tsim nyog, tiv tauj peb hnub no thiab cia peb pab koj nrhiav kev daws teeb meem zoo rau koj cov kev xav tau!
