Ceramic fiber ntau daim ntawv yog ib yam ntawm cov thermal rwb thaiv tsev ceramic fiber cov khoom uas zoo heev tsim nrog raw cov ntaub ntawv qib ceramic fiber nrog qis slag ntsiab lus los ntawm cov txheej txheem ntawm pulping, deslagging, pulp tov, fourdrinier forming, nqus dewatering, ziab, txiav thiab dov. uas tuaj yeem siv rau cov ntsaws ruaj ruaj, combustion chamber liners, kub sab saum toj linings
Ceramic fiber ntau daim ntawv muaj feem ntau ntawm purity alumino silicate fiber ntau thiab uas yog tsim los ntawm cov txheej txheem ntxuav fiber ntau. ceramic fiber paper manufacturing txheej txheem tswj cov ntsiab lus ntawm unfiberized txhaj tshuaj mus rau ib tug tsawg heev theem nyob rau hauv daim ntawv. Refractory ceramic fiber ntawv nta lub teeb yuag, qauv uniformity thiab tsis tshua muaj thermal conductivity, uas yog ib qho zoo meej tov rau kub rwb thaiv tsev, tshuaj corrosion kuj thiab thermal shock kuj.
Raws li kev pabcuam kub ceramic fiber ntau tuaj yeem muab faib ua ob hom:
Ceramic fiber ntau nrog 1260 ℃ kev pabcuam kub.
Ceramic fiber ntau nrog 1400 ℃ kev pabcuam kub.
