Silica cib yog ib hom kua qaub-ntxuav refractory khoom raug rho tawm haujlwm kub nrog silica li raw khoom, txiv qaub mis nyuj, hlau nplai thiab pulp pov tseg kua li binder thiab mineralizer. Nws muaj zog tiv taus acid slag, tab sis muaj zog eroded los ntawm alkaline slag, thiab yog ib qho yooj yim rau puas los ntawm Al2O3, K2O, Na2O thiab lwm yam oxides, thiab muaj zoo kuj rau CaO, FeO, Fe2O3 thiab lwm yam oxides. Lub silica cib muaj qhov kub thiab txias, qhov ntim me me nthuav dav, thiab zoo thermal conductivity. Qhov seem expansion ua kom ntseeg tau tias cov masonry muaj cua nruj zoo thiab lub zog muaj zog. Tam sim no, nws tseem yog cov khoom siv hluav taws xob zoo rau coke qhov cub, iav rauv, moj tej tawg rauv kub blast rauv, nonferrous smelting thiab pickling steelmaking rauv.
Raws li cov txheej txheem tsim khoom, silica cib muab faib ua cov silica cib, high-density silica cib, siab thermal conductivity silica cib, thiab lwm yam.
Kev xaiv ntawm silica raw cov ntaub ntawv: cov ntsiab lus ntawm SiO2 yog siab, tsis tsawg tshaj li 96 feem pua, cov crystalline hais me me, qhov nthuav me me, thiab cov ntsiab lus impurity tsawg dua 4 feem pua. Kev hloov pauv thiab qib ntawm kev xoob ntawm silica thaum lub sij hawm cua sov txheej txheem muaj kev cuam tshuam loj rau kev tsim cov silica bricks. Kev hloov pauv ntawm silica feem ntau yog qhov laj thawj tseem ceeb rau kev tawg ntawm silica bricks thaum raug rho tawm haujlwm. Silica nrog loj crystalline hais nthuav dav dua thaum raug rho tawm haujlwm
Lub zog tsim ntawm silica cib yuav tsum tsis txhob tsawg dua 100-150Mpa, thiab qhov ceev ntawm cib dawb yuav tsum tswj ntawm 2.2-2.3g/cm3.
Cov silica cib raug rho tawm haujlwm hauv qhov chaw tsis muaj zog, qhov siab tshaj plaws tua hluav taws kub qis dua 1430 degree, thiab lub sij hawm txuag hluav taws xob txaus feem ntau hloov pauv ntawm 20-48 teev.
