Siab Purity Fused Mullite
Dec 21, 2023
Fused mullite yog ua los ntawm high-purity quartz xuab zeb thiab muaj alumina, thiab yog smelted nyob rau hauv ib tug super-loj hluav taws xob arc rauv. Nws muaj xim dawb, tsis tshua muaj carbon residue, zoo-tsim koob zoo li siv lead ua, thiab siab flexural zog. Nws muaj cov yam ntxwv ntawm kev nthuav dav, thermal stability Nws muaj kev ruaj ntseg zoo, siab load softening point, me me-kub creep tus nqi, siab hardness, thiab zoo tsis kam mus tshuaj corrosion. Nws yog dav siv nyob rau hauv iav kiln hauv ob sab phlu cib, loj ironmaking moj tej tawg rauv kub moj tej tawg rauv cib, ceramic kiln rooj tog, saggers, Shed panels, petrochemical thiab lwm yam industries yog raw cov ntaub ntawv rau high-qib refractory ntaub ntawv.
