Dab tsi yog qhov txawv ntawm cov refractory cib thiab insulation bricks?

Lub luag haujlwm tseem ceeb ntawm thermal rwb thaiv tsev bricks yog ua kom lawv sov thiab txo cov cua sov. Thermal rwb thaiv tsev bricks feem ntau tsis ncaj qha mus kov cov nplaim taws, thaum refractory bricks feem ntau ncaj qha kov cov nplaim taws. Refractory bricks feem ntau yog siv los tiv thaiv cov nplaim taws. Feem ntau muab faib ua ob hom, uas yog unshaped refractories thiab zoo li tus refractories. Unshaped refractory khoom: tseem hu ua castable, nws yog ib tug tov hmoov granule muaj li ntawm ntau yam aggregates los yog aggregates thiab ib los yog ntau tshaj binders. Nws yuav tsum tau tov nrog ib lossis ntau dua cov kua thiab sib tov sib npaug thaum siv. Nws muaj zog liquidity. Cov ntaub ntawv zoo li refractory: feem ntau ua cov cib refractory, cov duab uas muaj cov qauv kev cai, thiab nws tseem tuaj yeem ua tiav ib ntus raws li qhov xav tau thaum tsim thiab txiav.

Lub ntsiab sib txawv ntawm thermal rwb thaiv tsev bricks thiab refractory bricks yog raws li nram no:

1. Kev ua haujlwm thermal rwb thaiv tsev

Lub thermal conductivity ntawm thermal rwb thaiv tsev cib feem ntau yog 0.2-0.4 (qhov nruab nrab kub 350 ± 25 ° C) w / mk, thaum lub thermal conductivity ntawm refractory bricks yog siab tshaj 1.0 (qhov nruab nrab kub 350 ± 25 ° C) w / mk, thiab thermal rwb thaiv tsev cib tuaj yeem tau txais. Lub thermal rwb thaiv tsev kev ua tau zoo ntawm Refractory Brick yog zoo dua li ntawm refractory cib.

2. Refractoriness

Lub refractoriness ntawm rwb thaiv tsev cib feem ntau qis dua 1400 degrees, thaum lub refractoriness ntawm refractory bricks yog siab tshaj 1400 degrees.

3. Cov ceev

Rwb thaiv tsev cib feem ntau yog cov khoom siv hluav taws xob hnyav, nrog qhov ceev ntawm 0.8-1.0g / cm3 thiab qhov ceev ntawm cov cib refractory yog qhov tseem ceeb tshaj 2.0g / cm3.

Feem ntau hais lus, refractory bricks muaj lub zog txhua yam, lub neej ua haujlwm ntev, tshuaj lom neeg ruaj khov, tsis muaj tshuaj lom neeg nrog cov ntaub ntawv thiab kub kub ua haujlwm. Lub siab kub ua haujlwm kub tuaj yeem ncav cuag 1900 ℃. Nws yog tshwj xeeb tshaj yog haum rau kub thiab tsis kub hloov qhov cub, hloov kho, hydroconverters, desulfurization tso tsheb hlau luam thiab methanizers nyob rau hauv chemical fertilizer nroj tsuag kom disperse roj thiab kua, thiab txhawb, npog thiab tiv thaiv catalysts. Nws tseem tuaj yeem siv rau hauv cov qhov cub kub kub thiab cov khoom siv hluav taws xob hloov pauv hauv kev lag luam hlau thiab hlau.

Refractory bricks muaj qhov zoo ntawm kev kub siab, lub zog muaj zog, muaj kev sib tsoo tsis zoo, lub neej ntev, thiab cov khoom siv tsis ntev, thiab cov khoom siv tsis ntev. Nws yog ib qho kev sib tsoo nruab nrab haum rau ntau yam sib tsoo tshuab.

Refractory bricks yog txawv heev los ntawm thermal rwb thaiv tsev cib, thiab lawv siv ib puag ncig, Scope thiab muaj nuj nqi yog txawv. Cov khoom sib txawv yuav raug siv rau hauv ntau txoj haujlwm. Thaum xaiv cov ntaub ntawv, peb yuav tsum txiav txim siab seb cov khoom siv refractory puas haum rau peb tus kheej siv raws li peb qhov xwm txheej.
