Kev piav qhia
Dawb Tabular Alumina yog cov khoom siv zoo, hluavtaws refractory uas tau siv dav hauv ntau lub lag luam rau nws cov khoom siv zoo heev, thermal, thiab tshuaj lom neeg. Nws yog tsim los ntawm sintering high-purity alumina hmoov ntawm qhov kub thiab txias, uas ua rau cov qauv siv lead ua tshwj xeeb uas muab cov khoom tshwj xeeb.
Dawb Tabular Alumina muaj qhov tsawg kawg nkaus purity ntawm 99.5 feem pua thiab ib tug dawb, ultra-zoo hmoov tsos. Nws muaj qhov siab melting point ntawm 2040 degree (3704 degree F), tsis tshua muaj thermal expansion coefficient ntawm 5.6 x 10^-6 / degree, thiab siab compressive zog ntawm 2600 MPa. Cov yam ntxwv no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau muaj qhov kub thiab txias, tiv thaiv kev puas tsuaj, qhov ruaj khov, thiab tshuaj lom neeg.

Dawb Tabular Alumina yog ib daim ntawv siab-purity ntawm txhuas oxide uas yog tsim los ntawm sintering alumina hmoov ntawm qhov kub thiab txias. Nws muaj cov qauv hexagonal siv lead ua tshwj xeeb uas ua rau nws yog ib qho khoom siv zoo heev rau kev siv hauv cov ntawv kub kub, xws li cov khoom siv refractory hauv cov furnaces thiab kilns. Nws muaj zog txhua yam muaj zog, zoo heev thermal shock resistance, thiab porosity tsawg ua rau nws zoo tagnrho rau siv nyob rau hauv abrasive thiab txiav cov cuab yeej, sib tsoo xov xwm, thiab raws li ib tug muab tub lim nyob rau hauv ntau yam composites.
