Alumina muab tub lim cov pob ntawm inert ceramic pob

Muaj ntau yam ntawm inert ceramic pob.Qhov alumina cov khoom siv tau muab faib ua pob sib tsoo, cov pob rov ua kom zoo dua, cov pob refractory, cov npas muab tub thiab lwm yam.Hais hauv tsab xov xwm no, peb yuav tsom mus rau kev siv cov inert alumina filler ball (solid).

Inert, raws li lub npe hais tias, nws tsis koom nrog tshuaj lom neeg.Nws yog ua los ntawm alumina hmoov tom qab tau calcined rau hauv cov hmoov ua lag luam, thiab tom qab ntawd calcined rau hauv cov txheej txheem high-density qauv los ntawm kev teb kiln thiab qhov kiln.Qhov ntom thiab ruaj khov tshuaj qauv zoo li zoo li ceramic, yog li nws tseem hu ua alumina ceramic pob.

Txawv los ntawm kev ua tiav ntawm cov khoom siv dav dav, alumina ceramics muaj Mohs hardness ntawm 9, thib ob tsuas yog pob zeb diamond, thiab lawv lub zog compressive thiab feem cuam tshuam yog qhov deb ntawm kev sib piv rau ceramics.Thaum tib lub sijhawm, lawv muaj qhov zoo tib yam li ceramics: Acid thiab alkali corrosion tsis kam, cov no yog qhov zoo Cov kev ua tau ua rau inert alumina muab npas ntau thiab ntau siv hauv kev lag luam.

Tam sim no, inert alumina muab cov pob yog siv ntau hauv cov khoom lag luam siab, xws li 90 / 92 / 95 / 99, uas yog siv dav hauv tshuaj thiab roj av kev lag luam raws li cov sau ntawv.Qhov cov khoom siv uas xav tau los ntawm cov kev lag luam no yuav tsum tiv thaiv qhov kev xeb ntawm cov kua qaub muaj zog thiab alkalis thiab lwm cov kuab tshuaj, thiab yuav tsum tiv taus qhov kub thiab kub siab, thiab tsis tuaj yeem koom nrog cov tshuaj tiv thaiv.Qhov no yuav tsum ua kom tau raws li qhov xav tau ntawm alumina muab tub lim, yog li nws muaj txiaj ntsig heev.
