Tsawg creep siab aluminium cib yog ib yam ntawm cov khoom siv refractory, feem ntau yog siv nyob rau hauv industrial kilns, iav kilns thiab lwm yam kub kub. Lub cib no muaj cov yam ntxwv ntawm siab refractory, qis creep, zoo thermal stability thiab tshuaj stability. Lub ntsiab tseem ceeb ntawm qis creep siab aluminium cib yog alumina (Al2O3). Cov hauv qab no yog qee qhov ntsuas lub cev thiab tshuaj lom neeg ntawm qis creep siab aluminium bricks:
1. Refractory: Lub refractory feem ntau yog nyob nruab nrab ntawm 1600-1800 degree, uas yog txiav txim siab los ntawm lub siab melting point ntawm nws lub ntsiab tivthaiv alumina.
2. Tus nqi nkag: Tus nqi nkag ntawm qis creep siab aluminium cib feem ntau yog nyob nruab nrab ntawm 0.1-0.4 feem pua . Qhov no txhais tau hais tias nyob rau lub sij hawm ntev ntawm qhov kub thiab txias, lub cib muaj tsawg deformation thiab pab tswj kev ruaj ntseg ntawm qhov cub.
3. Porosity: Lub porosity ntawm qis creep siab aluminium cib feem ntau yog nyob nruab nrab ntawm 15-25 feem pua . Lub porosity pom tseeb qhia txog qhov pore faib hauv lub cib, thiab qhov pom tseeb pom pom porosity pab txhim kho thermal stability thiab thermal shock kuj ntawm cib.
4. Kev Quav Quav: Qhov ntom ntom ntom ntom nti ntawm qis nkag siab lub siab txhuas txhuas feem ntau ntawm 2. {}. 8 g / cm³. Qhov ntom ntom cuam tshuam rau lub zog thiab hnav tsis kam ntawm cib.
5. Compressive zog: Lub zog compressive ntawm qis creep siab aluminium bricks feem ntau yog nyob nruab nrab ntawm 50-80 MPa. Lub siab compressive zog pab xyuas kom meej tias lub cib tsis tawg los yog deform nyob rau hauv high-temperature ib puag ncig.
6. Load softening kub: Lub load softening kub ntawm tsawg creep siab aluminium bricks feem ntau yog nyob nruab nrab ntawm 1450-1550 degree . Qhov ntsuas no qhia tau hais tias qhov kub ntawm lub cib pib deform nyob rau hauv ib lub siab, uas yog ib qho tseem ceeb heev rau high-temperature ib puag ncig xws li industrial kilns.
7. Thermal shock resistance: low creep high aluminium cib muaj thermal shock kuj zoo thiab tuaj yeem tiv taus qhov kub thiab txias hloov hauv qhov cub. Feem ntau, thermal shock resistance yog qhia nyob rau hauv tus naj npawb ntawm thermal shocks (1100 degree dej txias), xws li withstanding 20-30 los yog ntau thermal shocks.
8. Chemical stability: tsawg creep siab aluminium cib muaj corrosion kuj zoo thiab muaj peev xwm tiv taus qhov yaig ntawm ntau cov tshuaj. Nyob rau hauv ib puag ncig kub, lub cib no muaj qee yam corrosion kuj rau alkali hlau, sulfur, chlorine, thiab lwm yam.
