Mullite Cib
Hais txog Mullite Bricks
Mullite bricks yog ib lub siab aluminium refractory nrog mullite raws li lub ntsiab siv lead ua theem.Feem ntau, cov ntsiab lus ntawm alumina yog nruab nrab ntawm 65% thiab 75%.Ntxiv rau mullite, cov zaub mov uas muaj cov ntsiab lus alumina qis kuj tseem muaj me me ntawm vitreous theem thiab cristobalite.Cov ntsiab lus alumina siab dua kuj muaj me me ntawm corundum.
Mullite bricks muaj lub siab refractoriness, uas tuaj yeem ncav cuag 1790 ° C.Load softening pib kub yog 1600 ~ 1700 ℃.Lub zog compressive ntawm chav tsev kub yog 70-260MPa.Zoo thermal shock tsis kam.
Muaj ob hom sintered mullite cib thiab fused mullite cib.
Sintered mullite cib yog ua los ntawm high-alumina bauxite clinker ua cov khoom siv tseem ceeb, ntxiv me me ntawm cov av nplaum los yog cov bauxite raw li cov ntaub ntawv, thiab raug tsim thiab raug rho tawm haujlwm.Fused mullite bricks yog ua los ntawm high bauxite, muaj alumina thiab refractory av nplaum, thiab charcoal los yog coke nplua particles yog ntxiv raws li ib tug txo tus neeg sawv cev.Tom qab molding, lawv yog tsim los ntawm kev txo electrofusion.
Lub crystallization ntawm fused mullite yog loj dua li ntawm sintered mullite, thiab nws cov thermal shock kuj zoo dua li cov khoom sintered.Lawv qhov kub thiab txias ua haujlwm feem ntau yog nyob ntawm cov ntsiab lus ntawm alumina thiab qhov sib xws ntawm kev faib tawm ntawm mullite theem thiab iav.
Mullite bricks yog tsuas yog siv rau kub moj tej tawg qhov cub sab saum toj, moj tej tawg rauv lub cev thiab hauv qab, iav rauv regenerator, ceramic kiln, lub kaum sab xis ntawm cov roj av cracking system, thiab lwm yam.
Hais txog Sillimanite
Cov sillimanite cib muaj qhov zoo thermal stability ntawm qhov kub thiab txias, tiv thaiv iav kua yaig, me me ua paug rau iav kua.
Feem ntau haum rau kev pub noj channel, pub tshuab, raj rub lub tshuab thiab lwm yam khoom siv hauv kev lag luam iav, uas tuaj yeem txhim kho cov khoom tsim tau zoo.
