Ceramic fiber modules tam sim no dav siv nyob rau hauv ntau yam kilns thiab industrial furnaces. Lub realization ntawm thermal rwb thaiv tsev ntawm ceramic fiber modules mas yog nyob ntawm nws cov yam ntxwv ntawm tshav kub hloov lwm lub tsev.
Tom qab ntawd cov roj uas tsis muaj thermal conductivity nyob rau hauv qhov xwm txheej (tshwj tsis yog hydrogen) yog ib yam khoom uas tsis tshua muaj thermal conductivity thiab muaj peev xwm tsis tshua muaj cua sov hauv lub xeev zoo li qub. Lub thermal conductivity ntawm ceramic fibers yeej nyob ze rau cov roj. Qhov no yog vim hais tias ceramics fibers yog interwoven nrog cov khoom fibers, muaj roj, thiab muaj ib tug porosity ntawm 90%. Yam dab tsi cuam tshuam rau kev hloov hluav taws xob ntawm cov ntaub ntawv xws li ceramic fiber modules?
1. Cov nyhuv ntawm porosity
Cov khoom siv thermal rwb thaiv tsev muaj qhov porosity zoo dua, uas yog, qhov ntim ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom yog qhov zoo tshaj plaws hauv cov khoom siv no. Yog li ntawd, ceramic fiber module tau muab faib ua ntau qib raws li kev siv qhov kub thiab txias, thiab qhov ceev tau hloov kho raws li qhov ntau ntawm 210-260 raws li qhov siv tau.
2. Kev cuam tshuam ntawm huab cua
Qhov qis thermal conductivity ntawm ceramic fiber module yog raws li feem ntau gases, tab sis yog hais tias muaj high-kub gases xws li hydrogen los yog helium nyob rau hauv ib puag ncig, ceramic fiber ntau yuav tsis siv.
3. Kev cuam tshuam ntawm ntau qhov ntom ntom
Rau cov khoom siv ceramic, kom muaj cov thermal conductivity tsawg, qhov nyiam ntawm cov khoom siv fiber ntau yog 250kg / m3 lossis tsawg dua, thiab cov porosity yog siab dua 90%.
4. Lub hwj chim ntawm directionality
Nyob rau hauv txoj kev tsim ntawm ceramic fiber daim pam los yog ceramic fiber board, qhov ntev thiab dav kev taw qhia ntawm cheeb tsam yog lub ntsiab kev taw qhia. Ntxiv mus, lub thermal conductivity ntawm pem hauv ntej nto ntawm cov khoom fiber ntau yog me dua li ntawm sab saum toj. Yog li ntawd, sab nraum qab ntawm cov khoom fiber ntau yog nyob ze rau ntawm phab ntsa ntawm lub cub tawg thaum lub sij hawm daim ntawv thov, thiab pem hauv ntej nto yog ib tug high-temperature tiv tauj nto. Cov khoom siv fiber ntau tsis tuaj yeem ntsia tau rau ntawm phab ntsa ntawm lub qhov cub.
