Xaiv cov cib mullite rwb thaiv tsev uas tsis hnyav lossis cov cib refractory thaum tsim lub cub tawg? 2

Qhov sib txawv tseem ceeb ntawm mullite insulation bricks thiab refractory bricks yog raws li nram no:

1. Kev ua tau zoo ntawm kev rwb thaiv tsev: Qhov ua tau zoo ntawm cov cib rwb thaiv tsev feem ntau yog nruab nrab ntawm 0.2-0.4 (qhov nruab nrab kub 350 ± 25 ℃) w/mk, thaum qhov ua tau zoo ntawm cov cib refractory yog siab dua 1.0 (qhov nruab nrab kub 350 ± 25 ℃) w/mk Nws tuaj yeem xaus lus tias qhov ua tau zoo ntawm kev rwb thaiv tsev ntawm cov cib rwb thaiv tsev zoo dua li cov cib refractory.
2. Kev tiv thaiv hluav taws: Qhov kev tiv thaiv hluav taws ntawm mullite rwb thaiv tsev hluav taws cib feem ntau yog qis dua 1400 degrees, thaum qhov kev tiv thaiv hluav taws ntawm cov cib refractory yog siab dua 1400 degrees.
3. Qhov Ceev:Mullite rwb thaiv tsev cib hluav tawsFeem ntau yog cov khoom siv rwb thaiv tsev uas tsis hnyav, nrog rau qhov ceev feem ntau ntawm 0.8 thiab 1.0g/cm3, thaum cov cib refractory muaj qhov ceev feem ntau siab dua 2.0g/cm3. Feem ntau, cov cib refractory muaj lub zog kho tshuab siab, lub neej ua haujlwm ntev, kev ruaj khov tshuaj lom neeg zoo, tsis muaj tshuaj lom neeg nrog cov ntaub ntawv thiab tiv taus kub siab. Nws qhov kub siab tshaj plaws tuaj yeem ncav cuag 1900 ℃. Nws yog qhov tsim nyog rau cov cub tawg hloov pauv kub siab thiab qis, cov khoom hloov pauv, cov khoom hloov pauv hydrogenation, cov tank desulfurization, thiab cov cub tawg methanation hauv cov nroj tsuag chiv, nws ua lub luag haujlwm hauv kev faib cov roj thiab kua, txhawb nqa, npog, thiab tiv thaiv cov catalysts. Nws kuj tseem siv tau rau hauv cov cub tawg kub thiab cov khoom siv hloov pauv cua sov hauv kev lag luam hlau.
Cov cib refractory muaj qhov zoo ntawm qhov ceev ceev, lub zog siab, kev hnav tsis kam zoo, kev tiv thaiv corrosion zoo, coefficient qis ntawm thermal expansion, kev sib tsoo zoo, txo suab nrov zoo, lub neej ntev, cov ntaub ntawv tsis ua qias tuaj, thiab lwm yam. Nws yog cov khoom sib tsoo zoo uas haum rau ntau lub tshuab sib tsoo.
Qhov sib txawv ntawm cov cib refractory thiab mullite insulation fire bricks yog qhov tseem ceeb, vim tias lawv qhov chaw siv, qhov ntau thiab tsawg, thiab kev ua haujlwm yog txawv. Cov ntaub ntawv sib txawv yuav raug siv rau hauv cov xwm txheej sib txawv. Thaum xaiv cov ntaub ntawv, peb yuav tsum txiav txim siab seb cov khoom siv refractory twg haum rau peb tus kheej siv raws li peb qhov xwm txheej tiag tiag.
