Nyob rau lub Peb Hlis 245 daim ceramic fiber ntau yog ntim rau xa mus rau cov neeg siv khoom hauv Ixayees. Cov khoom zoo thiab tus nqi zoo thermal rwb thaiv tsev hauv Topower Refractory.
Ceramic fiber ntau, raws li cov khoom siv refractory, muaj qee yam thermal rwb thaiv tsev, thiab cov thermal rwb thaiv tsev cuam tshuam los ntawm thermal conductivity, yog li dab tsi yog qhov cuam tshuam rau nws cov thermal conductivity? Nov yog yam uas yuav tsum paub:
1. Khoom siv
Cov tshuaj nruab nrab txheej, cov qauv thiab kev sib sau ua ke ntawm aluminium silicate fiber. Thaum qhov ceev ntawm txhua yam ntawm cov khoom yog interphase, lub conductivity coefficient ntawm cov khoom uas muaj thermal conductivity kuj yog siab ceev: thermal conductivity feem ntau txo nrog qhov txo qis ntawm cov khoom ua haujlwm ceev, tab sis thaum txo qis rau qee qhov, nws nce. sai nrog qhov txo qis ntawm kev ua haujlwm ceev. Yog li ntawd, cov khoom siv thermal lub cev ntawm lub teeb yuag thermal rwb thaiv tsev cov ntaub ntawv ceramic fiber board yog tus cwj pwm los ntawm cov thermal conductivity me me thiab thermal conductivity loj.
Humidity: Cov conductance coefficient ntawm ceramic fiber ntau yuav txo qis tom qab nqus noo noo, thiab qhov kev sim qhia tau hais tias qhov txo qis los yog nce ntawm cov dej noo, cov conductance coefficient tuaj yeem nce lossis txo. Qhov no yog vim lub thermal conductivity nyob ntawm qhov sib piv ntawm thermal conductivity rau lub ntim kub muaj peev xwm, thiab ob qho tib si thermal conductivity thiab kub muaj peev xwm nce raws li cov dej ntsiab lus ntawm cov khoom nce. Tab sis tus nqi nce tsis zoo ib yam, uas txiav txim siab txoj cai ntawm kev hloov pauv ntawm cov conductivity coefficient.
2. Kub
Lub thermal conductivity ntawm aluminium silicate ceramic fiber ntau
feem ntau nce nrog qhov nce ntawm qhov kub thiab txias, tab sis qhov nce me me, tab sis lub zog tsis loj, feem ntau tsis suav nrog.
3. Heat flow kab cua sov ntws
Tej yam yooj yim thaum uas tig mus los yog perpendicular mus rau lub fiber extension kev taw qhia, siab thermal conductivity. Ceramic fiber ntau yog ua los ntawm fiber ntau los ntawm lub tshuab nqus tsev tsim staggered, tshav kub txaus yuav tsis txuas mus rau fiber ntau poob, yog li cov thermal conductivity yog me me, zoo thermal rwb thaiv tsev kev ua tau zoo.
Qhov tseem ceeb tshaj plaws indexes ntawm ceramic fiber paj rwb yog fiber ntau txoj kab uas hla thiab thermal stability. Ceramic fibers muaj ib txoj kab uas hla ntawm 24 microns. Cov fiber ntau zoo, me me ntom ntom, tsis tshua muaj thermal conductivity ntawm kev siv cov kub kub. Yog tias cov fiber ntau yog tuab thiab ntom, cov nyhuv ntawm daim ntawv thov tsis zoo tagnrho. Lub thermal stability ntawm fiber ntau yog qhov tseem ceeb dua. Tus nqi ntawm shrinkage kuj ncaj qha cuam tshuam rau thermal stability.
