Corundum mullite cib

Cov khoom lag luam zoo: tiv taus kub, tiv taus xeb, tiv taus oxidation, ruaj ntseg thermal zoo, thiab hloov pauv qis.

Daim ntawv thov khoom: Feem ntau siv hauv kev lag luam petrochemical, loj thiab nruab nrab qhov hluavtaws ammonia gasifier thiab cov khoom siv sib nqus cov khoom siv hluav taws xob ua kom sov, cov khoom siv hluav taws xob kub kub ua haujlwm txhawb cov khoom siv, thiab lwm yam.

khoom piav qhia

Corundum thiab mullite cib yog ua los ntawm kev ua kom huv siab corundum thiab mullite ua raw khoom, ua los ntawm kev kub siab thiab raug rho tawm ntawm qhov kub. Cov khoom muaj cov yam ntxwv ntawm kev tiv thaiv kub, tiv taus xeb, tiv taus oxidation, ruaj ntseg thermal zoo, thiab hloov pauv qis.

Kev piav qhia ntawm corundum mullite cib:

1. Cov ntaub ntawv hnyav muaj qhov zoo sib xws, lub zog muaj zog siab, tiv taus ntau yam roj cua corrosive, zoo thermal poob siab ruaj khov, zoo thermal conductivity, thiab hnav tsis kam.

2. Cov ntaub ntawv hnyav muaj cov qauv sab hauv zoo, muaj zog khov, tiv taus xeb, tiv taus cua sov, tiv taus oxidation, ua haujlwm kub thiab ua kom muaj cua sov tsawg.
