High quality mullite rwb thaiv tsev cibrefractory castable yog tsim los ntawm siab - lub zog mullite li aggregate, superfine hmoov thiab compound additives ntxiv. Nws muaj cov yam ntxwv ntawm siab refractoriness, siab zog, tsis tshua muaj thermal conductivity thiab tsawg bulk ceev, uas yuav txo tau lub thermal zog noj ntawm industrial furnaces thiab txo qhov hnyav ntawm lub qhov cub hauv ob sab phlu. Ntawm qhov siab - kub cov ntaub ntawv raw khoom, cov khoom siv raw hauv qab no tuaj yeem siv los ua cov khoom siv raw rau siab - kub castables siv siab tshaj 1200℃: ntxeem tau clinker los yog cov pob zeb porous xws li mullite, corundum, siab alumina, silica thiab magnesia khoom. Xws li castables tuaj yeem siv ncaj qha rau hauv ob sab ntawm cov cua sov ua haujlwm ntawm 1350 degree.
Mullite rwb thaiv tsev bricks yog siab alumina cib nrog mullite ua lub ntsiab theem. Al2O3 cov ntsiab lus feem ntau yog 40-70%. Dhau li ntawm mullite, tseem muaj me me iav theem thiab cristobalite. Lub teeb hnyav mullite cib tuaj yeem kov cov nplaim taws ncaj qha. Lawv tau dav siv los ua kev ua hauj lwm hauv ob sab phlu ntawm high temperature industrial furnace.
Raws li ntau qhov sib txawv, muaj lub teeb yuag mullite rwb thaiv tsev cib thiab siab ceev mullite rwb thaiv tsev cib. Raws li qhov sib txawv ntawm qhov kev pabcuam kub, muaj 1350 C, 1450 C, 1550 C mullite rwb thaiv tsev cib . 1550 C mullite rwb thaiv tsev cib feem ntau yog siv los ua cov kab ua haujlwm ntawm lub cub tawg vim muaj hluav taws kub.
Nta
1. Tsawg thermal conductivity, zoo thermal rwb thaiv tsev kev ua tau zoo
2. Tsawg thermal muaj peev xwm, zoo rau kev sib tshuam ntau lawm.
3. Tsawg cov ntsiab lus impurities: Tsawg Fe2O3 thiab alkali cov ntsiab lus, ua rau siab refractoriness.
4. Siab thermal crushing zog, refractoriness tuaj yeem ncav cuag 1790 degree. Refractoriness yog 1450-1600℃.Cold crushing zog yog 2-6 Mpa, thermal shock kuj zoo.
5. tuaj yeem txiav rau hauv cov duab tshwj xeeb, phim cov ntawv thov sib txawv.
Mullite rwb thaiv tsev bricksyog dav siv rau tawg rauv, kub moj tej tawg qhov cub, tej hub dov kilns, hluav taws xob ceramic tub rau khoom kiln, iav crucible, ua hauj lwm linings ntawm ntau yam hluav taws xob rauv thiab lwm yam. Lawv kuj siv raws li ru tsev ntawm kub moj tej tawg qhov cub, lub cev thiab hauv qab ntawm blast furnace, chamber ntawm iav rauv, ceramic sintering kiln, cracking system ntawm petrochemical kev lag luam thiab lwm yam.
