Mullite Cib

Mullite bricks yog high-alumina refractories uas feem ntau muaj cov siv lead ua theem mullite (3Al2O32SiO2). Cov ntsiab lus alumina feem ntau yog li ntawm 70 feem pua rau 80 feem pua. Cov cib ua los ntawm cov khoom siv refractory mullite muaj qhov siab refractoriness uas tuaj yeem tshaj 1790 degree.

Khoom Taw qhia

Kev piav qhia

Mullite cib, ua los ntawm hluavtaws fused mullite thiab sintered mullite, yog tsim los ntawm tes thiab raug rho tawm haujlwm hauv qhov cub kub kub. Mullite Bricks yog tsim nrog mullite ua cov khoom siv tseem ceeb thiab raug rho tawm haujlwm ntawm qhov kub thiab txias. Nws muaj ntau dua refractoriness mus txog 1790 degree, thiab nws pom tseeb pib softening kub yog 16001700 degree. Nws muaj qhov txias crushing zog ntawm 70260MPa. Nws yog thermally shock resistant.

Nta

Mullite Bricks muaj cov thermal expansivity tsawg, muaj thermal conductivity, siab thermal shock resistance, thiab high-temperature zog. Lawv tuaj yeem tiv taus qhov kub thiab txias rau lub sijhawm ntev yam tsis muaj softening. Lawv tuaj yeem tiv taus acid yaig, tab sis lawv tsis tuaj yeem ua haujlwm hauv qhov chaw oxidizing.

Daim ntawv thov

Mullite bricks muaj ntau yam zoo heev, nrog rau qhov kub thiab txias tsis kam, zoo thermal shock tsis kam, siab thermal conductivity, thiab ntau dua, uas ua rau nws yog ib qho kev xaiv nrov rau siv nyob rau hauv blast furnaces, kub blast qhov cub, thiab iav melting furnaces.
