Lub teeb hluav taws xob rwb thaiv tsev cib rau iav kilns tuaj yeem muab faib ua 6 pawg raws li lawv cov khoom sib txawv. Cov khoom siv dav tshaj plaws yog lub teeb yuag silica cib thiab diatomite cib. Lub teeb yuag rwb thaiv tsev cib muaj qhov zoo ntawm kev ua haujlwm zoo thermal rwb thaiv tsev, tab sis lawv lub siab tsis kam, slag tsis kam, thiab thermal shock kuj tsis zoo, yog li lawv tsis tuaj yeem tiv tauj ncaj qha nrog molten iav lossis nplaim taws.
1. Lub teeb yuag silica cib. Lub teeb silica rwb thaiv tsev cib yog cov khoom siv hluav taws xob rwb thaiv tsev ua los ntawm silica ua cov khoom siv tseem ceeb, nrog SiO2 cov ntsiab lus tsis pub tsawg dua 91%. Qhov ceev ntawm lub teeb yuag silica rwb thaiv tsev cib yog 0.9 ~ 1.1g / cm3, thiab nws cov thermal conductivity tsuas yog ib nrab ntawm cov silica bricks. Nws muaj qhov zoo thermal poob siab tsis kam, thiab nws qhov kub thiab txias hauv qhov load tuaj yeem ncav cuag 1600 ℃, uas yog ntau dua li cov av nplaum rwb thaiv tsev. Yog li ntawd, qhov siab tshaj plaws ua haujlwm kub ntawm silica rwb thaiv tsev cib tuaj yeem ncav cuag 1550 ℃. Nws tsis ntsws ntawm qhov kub thiab txias, thiab txawm tias muaj me ntsis expansion. Lub teeb silica cib feem ntau yog tsim nrog crystalline Quartzite raws li cov khoom siv raw, thiab cov khoom siv hluav taws xob xws li coke, anthracite, sawdust, thiab lwm yam ntxiv rau hauv cov ntaub ntawv raw los tsim cov qauv ntxeem tau thiab cov roj foaming tuaj yeem siv los tsim cov qauv ntxeem tau.
2. Diatomite cib: Piv nrog rau lwm cov rwb thaiv tsev lub teeb ci ci, diatomite cib muaj qis thermal conductivity. Nws kub ua hauj lwm txawv nrog purity. Nws qhov ua haujlwm kub yog feem ntau qis dua 1100 ℃ vim tias qhov shrinkage ntawm cov khoom yog qhov loj ntawm qhov kub thiab txias. Cov khoom siv raw ntawm diatomite cib yuav tsum raug rho tawm ntawm qhov kub siab dua, thiab silicon dioxide tuaj yeem hloov mus rau quartz. Cov txiv qaub kuj tseem tuaj yeem muab ntxiv ua cov ntawv khi thiab cov ntxhia pob zeb los txhawb kev hloov pauv ntawm quartz thaum tua hluav taws, uas muaj txiaj ntsig zoo rau kev txhim kho cov cua sov ntawm cov khoom thiab txo qis qis ntawm qhov kub thiab txias.
Qhov teeb meem tom ntej no peb yuav txuas ntxiv mus qhia txog kev faib tawm ntawmlightweight rwb thaiv tsev cibrau iav kiln. Thov nyob twj ywm!
