Cov tsos ntawm cov xim nthuav tawm los ntawm cov av nplaum castable tsis muaj dab tsi ua nrog nws cov khoom zoo.
Av nplaum castable yog qib qis castable thiab nws tau siv rau hauv cov kab hluav taws xob ntawm qhov kub hauv qab 1200 degree. Nws cov xim muaj feem xyuam nrog cov hmoov silicon ntxiv, cov xim ntawm silica fume yog qhov tsis tuaj yeem tswj tau, vim tias muaj ntau yam kev txiav txim siab xim, xim kuj tsis ruaj khov, yog tias cov xim nruj, yuav tsum ua kom meej meej, kom tsis txhob muaj qhov tsis tsim nyog. kev sib cav.
Cov xim ntawm micro-silica hmoov feem ntau muaj xim dawb, grey, grey, grey dub, dub thiab lwm yam. Muaj ntau ntau xim, feem ntau yog los ntawm kev tsim cov khoom siv hlau ntawm cov khoom siv raw thiab cov txheej txheem txiav txim siab, yog li txhua lub Hoobkas tsim cov silica fume yuav tsum yog qhov tshwj xeeb, hauv qee yam yuav tsum sib txawv.
Microsilica hmoov yog ib qho tseem ceeb raw khoom nyob rau hauv refractory castable. Tus nqi ntws ntawm castable tuaj yeem nce ntxiv los ntawm kev ntxiv silica hmoov rau castable. Silicon hmoov particle loj me me, spherical hais, yooj yim heev rau nkag mus rau qhov sib txawv me me ntawm castable, thiab ntxiv ntawm silicon hmoov muaj cov nyhuv txo cov dej zoo, tab sis kuj tuaj yeem txhim kho qhov ntom ntawm refractory castable, txo cov porosity, thiaj li. ua kom lub zog ntawm refractory castable zoo dua.
Nws yog unscientific los txiav txim qhov zoo ntawm av nplaum castable tsuas yog los ntawm cov tsos xim. Cov hmoov silicon yuav los ntawm cov tuam txhab sib txawv hauv cov khoom sib txawv yuav muaj xim sib txawv, tab sis nws tsis muaj dab tsi ua rau qhov zoo ntawm cov av nplaum castable.
Qhov zoo ntawm cov av nplaum castable muaj kev sib raug zoo nrog cov dej ntxiv, teem sijhawm, lub zog thiab ci. Yog tias dej ntau ntxiv thaum lub sij hawm tsim kho yog qhov tseem ceeb cuam tshuam rau nws qhov zoo, vim tias cov dej ntau dhau tau ntxiv thiab lub sijhawm teem sijhawm ntev, cov txheej txheem dej tom qab yuav muaj qee yam cuam tshuam, yog tias qhov kub kub ceev dhau, lossis qhov ci. lub sij hawm luv luv, nws yog tus yuam sij rau kev cuam tshuam qhov zoo ntawm castable.
Yog li ntawd, qhov zoo ntawm cov av nplaum castable muaj feem xyuam rau cov txheej txheem ntau lawm, kev tsim kho dej, teem sij hawm, thiab ci, tab sis tsis muaj dab tsi ua nrog cov tsos xim.
