Taw qhia txog av nplaum Thermal rwb thaiv tsev Lub teeb yuag Refractory Cib

Clay-based heat-insulating lightweight refractory bricks yog cov cua sov-insulating refractory cib nrog 30% mus rau 48% AL2O3 cov ntsiab lus ua los ntawm cov av nplaum refractory ua cov khoom tseem ceeb. Cov txheej txheem ntau lawm txais cov txheej txheem hlawv-tawm ntxiv cov cim thiab cov txheej txheem ua npuas dej. Siv cov av nplaum refractory, ntab hlaws, thiab refractory av nplaum clinker ua raw cov ntaub ntawv, ntxiv binders thiab sawdust, batching, mixing, molding, drying, thiab firing kom tau ib tug tej yam ceev ntawm 0.3 ~ 1.5g / cm3. Cov zis ntawm cov av nplaum insulating cib nyiaj ntau tshaj ib nrab ntawm tag nrho cov zis ntawm insulating refractory bricks.

Raws li Suav tus qauv (GB 3994-1983), av nplaum rwb thaiv tsev cib muab faib ua NG-1.5, NG-1.3a, NG-1.3b, NG-1.0, NG-0.9, NG-0.8, NG-0.7, NG raws li mus rau lawv tej density. -0.6, NG—0.5, NG—0.4 10 qib.
