Dab tsi yog qhov sib txawv ntawm qib siab alumina refractory cib thiab av nplaum refractory cib?

Dab tsi yog qhov sib txawv ntawm qib siab alumina refractory cib thiab av nplaum refractory cib?

1. Cov tshuaj PH tus nqi ntawm cov av alumina refractory siab yog rau cov cib nruab nrab thiab alkaline refractory, thiab cov av nplaum ua rau cov cib cib ua rau nruab nrab thiab kua qaub refractory cib.

2. Ntxiv nrog rau qhov ua rau cua sov poob siab ntawm alumina refractory cib, lwm cov cib hluav taws kub hnyiab tsis zoo li cov av nplaum refractory cib. Feem ntau, hauv kev tsim cov kilns thiab lwm yam khoom siv cua sov, yog tias cov av nplaum tuaj yeem siv tau cov cib, cov av alumina siab tau siv rau kev ua masonry.

3. High alumina refractory bricks yog aluminium silicate refractory bricks nrog Al2O3 cov ntsiab lus ntau dua 48%. Cov av nplaum hluavtaws ua los ntawm cov khoom siv av nplaum nrog Al2O3 cov ntsiab lus ntawm 30% -40% txhuas cov khoom siv silicate.

4. Cov av cib muaj cov cua sov ua tau zoo thiab tiv taus cua txias thiab cua sov sai; qhov kub ntawm qhov kub ntawm alumina refractory cib nyob ntawm qhov ua haujlwm sintering ntawm cov khoom siv raw ntawm bauxite.

5. Qhov kub ua kom sov ntawm cov alumina refractory cib sib txawv nrog cov ntsiab lus ntawm Al2O3. Cov av nplaum hluavtaws hluavtaws muaj qhov kub ua kom sov qis, ntsws ntawm qhov kub siab, thiab muaj cua sov ua kom sov li 15% -20% qis dua cov cib silica.
