Topower Rwb thaiv tsev mullite firebrick yog ib yam zoo ntawm cov ntaub ntawv zoo refractory rwb thaiv tsev rau kev tiv thaiv kub nrog cov yam ntxwv ntawm lub teeb yuag, tsis tshua muaj thermal conductivity, thermal rwb thaiv tsev thiab siab compression zog nyob rau hauv kub kub furnaces los yog kilns.
Kev tsim cov txheej txheem ntawm mullite rwb thaiv tsev cib
Rwb thaiv tsev Mullite bricks yog ib hom rwb thaiv tsev cib. Lawv yog cov khoom siv high-aluminium refractory nrog mullite (3Al₂O₃・2SiO₂) ua lub ntsiab siv lead ua theem. Cov ntsiab lus ntawm alumina dav dav yog nyob nruab nrab ntawm 65% thiab 75%, ntawm cov JM23 muaj kev ua haujlwm siab. Cov cib no tau siv dav hauv ntau yam kev lag luam vim nws qhov kub thiab txias tsis kam, zoo thermal poob siab, tsis tshua muaj thermal conductivity thiab zoo tshuaj stability, tshwj xeeb tshaj yog nyob rau hauv high-temperature furnaces nyob rau hauv cov hlau, iav, ceramics thiab lwm yam industries. Ntawm lawv, JM23 muaj tus nqi siab thiab siv dav.
Raws li lub siab zoo alumina refractory, zus tau tej cov mullite rwb thaiv tsev refractory cib txais zoo zoo thiab ntshiab raw cov ntaub ntawv, uas alumina account rau 42% - 72%. Ntawm lawv, cov uas muaj cov ntsiab lus alumina qis dua kuj muaj cov iav theem thiab cristobalite, thiab cov uas muaj cov ntsiab lus alumina siab dua kuj muaj corundum uas yog qib qib siab. Mullite insulating cib muaj siab refractoriness, uas tuaj yeem ncav cuag 1790 degree (3254℉). Thawj qhov kub thiab txias ntawm load softening yog 1600-1700 degree (2912-3092℉), thiab compressive zog ntawm chav tsev kub yog 70-260MPa. Cov ntsiab lus tseem ceeb ntawm mullite insulating cib yog sib xyaw mullite thiab bauxite nrog me me ntawm av nplaum.
Raws li ib tug series ntawm cov txheej txheem ntau lawm, topower mullite rwb thaiv tsev bricks yog los ntawm kev soj ntsuam xyuas kom zoo zoo.
Nws cov yam ntxwv tseem ceeb thiab qhov zoo muaj xws li:
Cov nyhuv thermal rwb thaiv tsev zoo: Nws muaj cov yam ntxwv thermal conductivity tsawg thiab tuaj yeem txo qhov kub poob.
Pom tseeb lub zog-txuag nyhuv: Tsawg kub yaj thiab tsis tshua muaj thermal conductivity ua kom nws khaws cov cua sov tsawg heev hauv kev ua haujlwm tsis sib xws.
Tsawg impurity cov ntsiab lus: Cov ntsiab lus ntawm oxides xws li hlau thiab alkali hlau yog tsawg heev, yog li cov refractoriness siab, thiab cov ntsiab lus txhuas siab ua rau nws muaj kev ua tau zoo hauv qhov chaw txo qis.
High kub compressive zog: xyuas kom meej lub zog thiab stability ntawm lub masonry.
Mullite rwb thaiv tsev firebricks feem ntau yog dawb thiab tuaj yeem hu ncaj qha rau cov nplaim taws. Lawv feem ntau yog siv rau hauv ob sab phlu thiab rwb thaiv tsev txheej ntawm industrial furnaces xws li sab saum toj ntawm kub moj tej tawg rauv, moj tej tawg rauv lub cev thiab hauv qab, iav melting rauv regenerator, ceramic sintering kiln, thiab lub kaum sab xis ntawm cov roj av cracking system.
