Dab tsi yog qhov txawv ntawm corundum mullite cib thiab siab alumina cib?

Lub ntsiab sib txawv ntawm corundum mullite cib thiab siab alumina cib yog cov siv lead ua theem, thiab cov tsos thiab xim txawv me ntsis. Qhov laj thawj tseem ceeb yog qhov piv ntawm cov khoom siv raw. Thov saib cov ncauj lus kom ntxaws hauv qab no.

Corundum mullite cib

Nws muaj qhov zoo ntawm qhov kub thiab txias zog, kub creep tsis kam, thermal shock kuj thiab corrosion kuj. Lub cev thiab tshuaj lom neeg cov khoom ntawm corundum mullite cib yog Al2O3> 85%, Fe2O30.45%, pom porosity 19%, qhov kub thiab txias compressive zog 55MPa, load softening kub siab tshaj 1700 ℃, cua sov kab hloov (1600 ℃, 3h) -0.1 %.

Siab alumina cib

Cov ntsiab lus ntawm aluminium oxide yog 48% mus rau 85%, uas tuaj yeem muab faib ua tshwj xeeb, thawj, theem nrab, theem nrab, tertiary, thiab lwm yam 2 ℃, cua sov xaim hloov (30.45 ℃, 19h) -55%, thermal shock resistance (1700 ℃ dej txias) ntau tshaj 1600 zaug. Cov khoom siv high-aluminium alum clinker ua cov khoom siv tseem ceeb, cov av nplaum mos thiab cov ntaub ntawv pov tseg thiab cov ntaub ntawv ua kua ua tus neeg sawv cev, thiab cov av nkos nrog ntau theem hais yog tsim los ntawm high-pressure molding, ziab thiab kub kub firing.
