Kev ua tau zoo thiab kev siv ntawm Anti Spalling High Alumina Brick

Anti spalling siab alumina cib yog ib hom siab alumina cib uas tiv taus kom txias sai thiab cua sov los ntawm kev ntxiv zircon hmoov rau cov txheej txheem tsim cov khoom qub ntawm siab alumina cib. Qhov sib ntxiv ntawm zircon hmoov txhim kho cov ntxhia theem qauv ntawm cov khoom nyob rau hauv lub high-temperature sintering txheej txheem. Siv qhov sib txawv expansion coefficients ntawm zirconia, corundum thiab mullite theem, muaj qhov sib txawv me ntsis, tsim microcracks, txo qhov kev puas tsuaj ntawm thermal stress. Nyob rau tib lub sijhawm, qhov kev ua tau zoo ntawm zirconia kuj tseem txhim kho lub toughness ntawm cov khoom. Yog li ntawd, zircon hmoov siab aluminium cib ntxiv, thiab nws cov kev ua haujlwm tiv thaiv kev ua haujlwm zoo dua rau kev ua haujlwm siab aluminium cib. Al2O3 70 feem pua ​​​​siab aluminium cib yog dej-txias ntawm 1100 degree, Lub sij hawm ntawm ceev ceev txias thiab cua sov tsis kam yog feem ntau 7-8 zaug, thaum lub sij hawm ntawm spalling resistant siab alumina cib feem ntau yog {{6} } sijhawm. Anti stripping siab alumina cib feem ntau siv hauv cov cement kilns, cua sov rauv, kiln rooj tog cib, thiab lwm yam.
