Khoom thiab kev siv ntawm mullite rwb thaiv tsev cib
Mullite rwb thaiv tsev cib hais txog ib yam khoom siab alumina refractory nrog mullite ua lub ntsiab crystalline theem. Mullite cib muaj lub siab refractoriness thiab tuaj yeem ncav cuag ntau tshaj 1790. Nws yog siv los tsim cov thermal rwb thaiv tsev txheej ntawm qhov kub kub qhov cub, rhaub thiab muaj qhov cub. Nws muaj qhov zoo ntawm qhov kub thiab txias tsis kam, kub stability thiab thermal conductivity ntawm qhov kub thiab txias, yog li nws yog feem ntau siv rau hauv cov tub ntxhais ntawm kub kub furnaces, xws li furnaces, nozzles, kub cua kub thiab roj ducts.
Qhov zoo ntawm mullite rwb thaiv tsev bricks yog nws qhov kub thiab txias stability, hnav tsis kam thiab corrosion kuj. Nws tseem tuaj yeem tuav nws cov qauv qub thiab kev ua haujlwm ntawm qhov kub thiab txias, tsis muaj deformation, tawg lossis shrinkage, thiab tuaj yeem tiv taus qhov yaig ntawm ntau yam tshuaj lom neeg. Tsis tas li ntawd, mullite rwb thaiv tsev cib kuj muaj cov thermal conductivity tsawg, uas tuaj yeem txo cov cua sov kom zoo thiab txhim kho lub zog ntawm lub cub tawg.
Nyob rau hauv kev siv tswv yim, mullite rwb thaiv tsev bricks yog dav siv nyob rau hauv ntau yam high-temperature furnaces, iav manufacturing, hlau thiab hlau smelting, tshuaj lom neeg kev lag luam thiab lwm yam teb. Nws tuaj yeem tsis tsuas yog ua kom muaj txiaj ntsig thiab ruaj khov ntawm cov txheej txheem tsim khoom, tab sis kuj tseem txhim kho qhov zoo thiab cov khoom tsim tawm. Tsis tas li ntawd, mullite rwb thaiv tsev cib kuj tau siv dav hauv aerospace, kev tsim tsheb thiab lwm yam kev lag luam los muab kev ntsuas hluav taws xob zoo rau cov khoom siv kub.
Nws yuav tsum raug sau tseg tias tseem muaj qee qhov kev txwv hauv daim ntawv thov ntawm mullite rwb thaiv tsev cib, xws li nws tsis tshua muaj zog dabtsi yog khoov thiab yooj yim rau kev puas tsuaj los ntawm kev cuam tshuam sab nraud thiab siab. Yog li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau kev tiv thaiv thaum siv kom tsis txhob muaj kev puas tsuaj rau sab nraud. Nyob rau tib lub sijhawm, rau kev tsim thiab tsim cov txheej txheem ntawm lub qhov cub kub, nws tseem yuav tsum tau ua cov khoom tsim nyog xaiv thiab kev teeb tsa raws li kev ua tau zoo ntawm mullite rwb thaiv tsev cib.
Feem ntau, Mullite rwb thaiv tsev cib yog ib yam ntawm lub teeb yuag rwb thaiv tsev refractory nrog zoo kub kub kev ua tau zoo thiab ntau yam kev siv. Nws cov yam ntxwv tseem ceeb ntawm kev ua tau zoo suav nrog kev kub siab ua haujlwm zoo, kub kub stability, hnav tsis kam thiab corrosion kuj. Hauv daim ntawv thov txheej txheem, mullite rwb thaiv tsev cib tuaj yeem ua kom cov txheej txheem ntau lawm thiab ruaj khov, txhim kho cov khoom zoo thiab cov khoom tsim tawm. Tib lub sijhawm, nws kuj tau siv dav hauv aerospace, tsheb tsim thiab lwm yam haujlwm. Txawm li cas los xij, nyob rau hauv tus txheej txheem ntawm kev siv, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau nws cov kev txwv thiab ua raws li kev tiv thaiv kev tiv thaiv.
