Lub teeb yuag Silica rwb thaiv tsev cib txais yuav muab faib ua silica ore ua raw khoom. qhov tseem ceeb particle loj tsis ntau tshaj 1 hli, nyob rau hauv ntau tshaj 90% particle loj yog tsawg tshaj li 0.5 hli. silicate rwb thaiv tsev cib yog tsim los ntawm kev ntxiv cov khoom flammable nyob rau hauv lub nra hnyav los yog siv cov pa roj npuas los tsim cov qauv ntxeem tau los ntawm kev tua hluav taws, silicate rwb thaiv tsev cib kuj tuaj yeem ua rau cov khoom tsis raug hlawv.
Lub teeb yuag Silica rwb thaiv tsev cib muab cov ntaub ntawv raw thiab dej rau hauv cov khoom siv kneading raws li ib qho kev faib ua feem thiab ces kneaded rau hauv av, zoo li cov av nkos rau hauv bricks los ntawm molding los ntawm lub tshuab los yog manpower. Tom qab ntawd qhuav cov cib kom txog thaum cov dej seem tshuav qis dua 0.5%, uas tiv thaiv lub ntim nthuav tawm los ntawm kev hloov pauv siv lead ua SiO2 thiab tua cov cib zoo li qhov kub thiab txias.
