Khoom Taw Qhia Ntawm Mullite Cib
High alumina refractory nrog mullite (Al2O3•SiO2) ua lub ntsiab crystalline theem. Feem ntau, cov ntsiab lus alumina nyob nruab nrab ntawm 65% thiab 75%. Ntxiv nrog rau mullite, cov ntsiab lus qis alumina kuj muaj me me ntawm iav theem thiab cristobalite; Cov ntsiab lus alumina siab dua kuj muaj cov ...
High alumina refractory nrog mullite (Al2O3•SiO2) ua lub ntsiab crystalline theem. Feem ntau, cov ntsiab lus alumina nyob nruab nrab ntawm 65% thiab 75%. Ntxiv nrog rau mullite, cov ntsiab lus qis alumina kuj muaj me me ntawm iav theem thiab cristobalite; Cov ntsiab lus alumina siab dua kuj muaj me me ntawm corundum. Siab refractoriness, mus txog 1790 degree lossis ntau dua. Load softening pib kub 1600 ~ 1700 degree. Compressive zog 70 ~ 260MPa ntawm chav tsev kub. Zoo thermal shock tsis kam.
Mullite cib yog ua los ntawm cov phaj corundum txawv teb chaws thiab siab purity fused fused corundum ua cov ntaub ntawv tseem ceeb, siv cov txheej txheem ultrafine hmoov ntxiv, los ntawm kev sib tov, ziab, molding, thiab firing nyob rau hauv high-temperature spindle kiln. Mullett cib yog dav siv nyob rau hauv residual-roj gasifier, thib ob-theem hloov dua siab tshiab rauv ntawm hluavtaws ammonia, carbon dub reactor thiab refractory kiln. Cov duab loj, lub cev thiab tshuaj index thiab kev pabcuam lub neej ntawm cov khoom ua tau raws li cov neeg siv khoom xav tau.
Muaj sintered mullite cib thiab fused mullite cib.
1. Sintered mullite cib yog ua los ntawm high bauxite clinker raws li lub ntsiab raw khoom, ntxiv me me ntawm av nplaum los yog raw bauxite raws li ib daim ntawv cog lus, los ntawm kev tsim thiab firing.
2. Fused mullite cib nrog alumina, muaj alumina thiab refractory av nplaum ua raw cov ntaub ntawv, ntxiv charcoal los yog coke nplua particles raws li txo tus neeg sawv cev, tom qab tsim siv txo fused txoj kev los tsim. Lub crystallization ntawm fused mullite yog loj dua li ntawm sintered mullite, thiab thermal shock kuj zoo dua li cov khoom sintered. Lawv qhov kub thiab txias kev ua tau zoo feem ntau yog nyob ntawm cov ntsiab lus ntawm alumina thiab qhov sib xws ntawm kev faib tawm ntawm mullite theem nrog iav.
Nws yog tsuas yog siv nyob rau hauv kub moj tej tawg rauv saum toj, moj tej tawg rauv lub cev thiab hauv qab, iav rauv regenerator, ceramic sintering kiln, lub kaum sab xis ntawm cov roj av cracking system, thiab lwm yam.
