Corundum mullite cib yog ib hom ntawm refractory cib siv nyob rau hauv high-temperature daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog hnyav thermal thiab mechanical stresses. Nws yog tsim los ntawm corundum (-Al2O3) thiab mullite (3Al2O3·2SiO2). Cov ntaub ntawv no muaj cov thermal stability zoo heev, tshuaj tiv thaiv, thiab txhua yam muaj zog.
Nrog nws qhov kub thiab txias tsis kam, corundum mullite cib tuaj yeem tiv taus qhov kub siab tshaj 1600 degree (2912 degree F) yam tsis tau poob nws cov qauv kev ncaj ncees. Qhov kev ruaj ntseg thermal no yog qhov tseem ceeb rau cov ntawv thov uas muaj cov cua sov hnyav, qhov twg cov khoom siv tsis zoo.
Tsis tas li ntawd, corundum mullite cib nthuav tawm cov tshuaj tiv thaiv zoo heev, ua rau nws tiv taus corrosion los ntawm acids, alkalis, thiab molten hlau. Qhov kev tiv thaiv no ua kom lub neej ntev thiab kev ntseeg siab nyob rau hauv qhov chaw hnyav hnyav uas muaj cov khoom corrosive ntau.
Lub cib tsis tshua muaj thermal conductivity pab kom txo tau cov cua sov hloov thiab txhim kho lub zog ua haujlwm hauv cov txheej txheem kub. Nws cov neeg kho tshuab siab zog thiab tsis kam rau thermal shock xyuas kom durability thiab kev cia siab rau hauv kev thov kev thov.

Kev tsim cov txheej txheem ntawm corundum mullite cib
Corundum mullite cib feem ntau yog tsim nrog cov khoom sib xyaw ua ke. Txais yuav mullite granule ua cov aggregate thiab - Al2O3 hmoov raws li cov khoom siv hmoov. Thiab tseem tuaj yeem siv fused lossis sintered corundum granule ua cov aggregate thiab synthesized mullite hmoov raws li cov khoom siv hmoov. Burdening ntawm aggregate thiab hmoov cov ntaub ntawv raws li ib tug piv txwv thiab grain loj faib sib tov nrog binding tus neeg sawv cev ntawm sulfite pulp pov tseg kua nyob rau hauv kev txiav txim. Tom qab ua tiav kev sib xyaw, siv kev sib txhuam cib xovxwm lossis hydraulic cib xovxwm los pwm rau hauv cov duab. Thiab tom qab ntawd tua cov cib ntsuab nyob rau hauv qhov kub ntawm 1650 ~ 1750 degree tom qab ziab.
Daim ntawv thov ntawm corundum mullite cib
Corundum mullite cib feem ntau siv hauv kev lag luam xws li steelmaking, petrochemical, ceramics, thiab iav manufacturing. Lawv tau ua haujlwm nyob rau hauv thaj chaw xws li kiln linings, furnaces, reactors, thiab lwm yam khoom siv kub kub uas tiv thaiv thermal shock thiab puas yog qhov tseem ceeb.
