Kev faib tawm ntawm cov cib rwb thaiv tsev sib dua rau cov qhov cub iav 1

Cov cib rwb thaiv tsev sib dua rau cov qhov cub iav tuaj yeem muab faib ua 6 pawg raws li lawv cov khoom siv raw sib txawv. Cov uas siv dav tshaj plaws yog cov cib silica sib dua thiab cov cib diatomite. Cov cib rwb thaiv tsev sib dua muaj qhov zoo ntawm kev ua haujlwm rwb thaiv tsev zoo, tab sis lawv qhov kev tiv taus siab, kev tiv taus slag, thiab kev tiv taus thermal poob siab tsis zoo, yog li lawv tsis tuaj yeem sib cuag ncaj qha nrog cov iav yaj lossis nplaim taws.

1. Cov cib silica sib dua. Cov cib silica rwb thaiv tsev sib dua yog cov khoom siv rwb thaiv tsev uas ua los ntawm silica ua cov khoom siv tseem ceeb, nrog rau SiO2 cov ntsiab lus tsis pub tsawg dua 91%. Qhov ceev ntawm cov cib silica rwb thaiv tsev sib dua yog 0.9 ~ 1.1g / cm3, thiab nws cov thermal conductivity tsuas yog ib nrab ntawm cov cib silica ib txwm muaj. Nws muaj kev tiv thaiv thermal zoo, thiab nws qhov kub thiab txias softening hauv qab load tuaj yeem ncav cuag 1600 ℃, uas yog siab dua li ntawm cov cib av nplaum rwb thaiv tsev. Yog li ntawd, qhov kub ua haujlwm siab tshaj plaws ntawm cov cib silica rwb thaiv tsev tuaj yeem ncav cuag 1550 ℃. Nws tsis ntsws ntawm qhov kub siab, thiab txawm tias muaj kev nthuav dav me ntsis. Cov cib silica sib dua feem ntau yog tsim los ntawm crystalline Quartzite ua cov khoom siv raw, thiab cov tshuaj sib xyaw xws li coke, anthracite, sawdust, thiab lwm yam raug ntxiv rau hauv cov khoom siv raw los tsim cov qauv porous thiab txoj kev ua npuas roj kuj tseem siv tau los tsim cov qauv porous.
2. Cov cib diatomite: Piv nrog rau lwm cov cib rwb thaiv tsev uas tsis hnyav, cov cib diatomite muaj cov cua sov qis dua. Nws qhov kub ua haujlwm sib txawv nrog kev huv. Nws qhov kub ua haujlwm feem ntau qis dua 1100 ℃ vim tias qhov shrinkage ntawm cov khoom loj heev ntawm qhov kub siab. Cov khoom siv raw ntawm cov cib diatomite yuav tsum tau hlawv ntawm qhov kub siab dua, thiab silicon dioxide tuaj yeem hloov pauv mus ua quartz. Lime kuj tseem tuaj yeem ntxiv ua tus binder thiab mineralizer los txhawb kev hloov pauv ntawm quartz thaum hlawv, uas yog qhov zoo rau kev txhim kho qhov tiv taus cua sov ntawm cov khoom thiab txo qhov shrinkage ntawm qhov kub siab.
Tsab xov xwm tom ntej no peb yuav txuas ntxiv qhia txog kev faib tawm ntawmcib rwb thaiv tsev sib duarau cov qhov cub iav. Thov nyob twj ywm mloog!
