Cov khoom siv raw ntawmtabular aluminayog alumina hmoov, uas yog tsim los ntawm sintering ntawm qhov kub thiab txias qis tshaj qhov melting point ntawm corundum nyob rau hauv ib tug ultra-siab kub kiln, cua kub ceev thiab ceev ceev txias. Tabular alumina ntawm ntau qhov sib txawv uas peb pom txhua hnub yog tsim tom qab kev sib tsoo zoo, shaping thiab ziab. Niaj hnub no, kuv xav qhia txog cov yam ntxwv ntawm kev ua haujlwm ntawm tabular alumina.
Nyob rau hauv cov txheej txheem ntawm tabular alumina, tsis muaj additives ntxiv, yog li nws purity yog siab thiab nws grain hardness kuj loj. Tabular alumina muaj thermal load zog, tsis tshua muaj thermal shrinkage, siab ceev thiab tsis tshua muaj huab cua permeability, thiab tshwj xeeb tshaj yog zoo hnav tsis kam. Muaj ntau qhov kaw me me hauv cov nplej ntawm tabular alumina, yog li nws muaj qhov zoo dua thermal shock stability. Tabular alumina yog resistant rau tshuaj corrosion. Feem ntau alkalis thiab inorganic acids tsis cuam tshuam rau tabular alumina, tsuas yog hydrofluoric acid thiab phosphoric acid.
Qhov kev ua tau zoo no ua rau tabular alumina yog cov khoom siv zoo tshaj plaws rau cov khoom siv raw khoom refractory. Nws tuaj yeem siv tsis tau tsuas yog raws li kev sib sau ua ke, tab sis kuj yog ib qho ntxiv rau lwm cov khoom siv high-alumina monolithic refractory.
Tabular alumina tuaj yeem siv rau hauv daim ntawv thov ntawm fused corundum lossis dawb corundum los txhim kho kev ua haujlwm ntawm cov ntaub ntawv refractory.
Tabular alumina yog siv rau hauv cov rooj tog zaum hauv cov khoom siv ceramic los txhim kho nws cov khoom. Xws li kev txhim kho thermal shock stability thiab deformation kuj ntawm ceramic rollers; txhim kho lub neej ntawm saggers thiab shed daim hlau siv rau high-temperature ceramics.
Tsis tas li ntawd, phaj-zoo li tus corundum kuj tseem siv tau los ua ib qho insulator, thiab tseem tuaj yeem siv los ua qhov tsis tshua muaj porosity, siab zog thiab high-purity catalyst cab kuj rau kev kub siab.
