Ceramic fiber board yog ua tiav los ntawm cov txheej txheem ntub dej nqus. Lub zog ntawm cov khoom no yog siab dua li daim pam fiber ntau thiab lub tshuab nqus tsev tsim muaj kev xav. Nws yog qhov tsim nyog rau qhov chaw kub kub uas cov khoom muaj qhov yuav tsum tau muaj zog steel.
01 Kub muaj qhov cuam tshuam ncaj qha rau cov thermal conductivity ntawm txhua yam ntawm ceramic fiberboard rwb thaiv tsev cov ntaub ntawv. Lub thermal conductivity ntawm cov ntaub ntawv nce nrog qhov nce ntawm qhov kub thiab txias.
02 Tag nrho cov khoom siv rwb thaiv tsev muaj cov qauv ntxeem tau, yooj yim nqus dej. Thaum cov dej noo ntau dua 5 feem pua -10 feem pua, cov dej noo ntawm cov khoom siv nyob rau hauv ib feem ntawm qhov chaw stomatal sau los ntawm huab cua, ua rau cov thermal conductivity nce ntau.
03 bulk ceev yog ib qho kev xav ncaj qha ntawm qhov porosity ntawm cov khoom, vim hais tias cov thermal conductivity ntawm cov roj theem feem ntau tsawg dua thermal conductivity ntawm cov khoom theem, yog li cov thermal rwb thaiv tsev ntawm cov khoom muaj ib tug loj porosity, uas yog ib tug ntau yam ntawm density. me me qhov ntom ntom. Feem ntau, nce porosity lossis txo qhov ntom ntom yuav ua rau txo qis hauv thermal conductivity.
04 Nyob rau hauv cov ntaub ntawv rwb thaiv tsev ntawm ceramic fiber board, feem ntau ntawm cov cua sov yog ua los ntawm cov roj nyob rau hauv lub pores. Yog li ntawd, cov thermal conductivity ntawm cov khoom siv thermal rwb thaiv tsev ntawm cov khoom feem ntau txiav txim siab los ntawm hom roj ntim. Yog hais tias helium los yog hydrogen tau sau rau hauv cryogenic engineering, nws tuaj yeem suav tias yog thawj qhov kev kwv yees kwv yees, thiab cov thermal conductivity ntawm thermal rwb thaiv tsev cov ntaub ntawv yog sib npaug rau cov gases, vim hais tias cov thermal conductivity ntawm helium thiab hydrogen kuj loj.
05 Qhov tshwj xeeb kub muaj peev xwm ntawm cov khoom siv thermal rwb thaiv tsev rau kev suav cov txheej txheem thermal rwb thaiv tsev hauv cov cua txias thiab cua sov ntawm qhov xav tau txias (los yog cua sov). Ntawm qhov kub thiab txias, qhov tshwj xeeb kub muaj peev xwm ntawm tag nrho cov khib nyiab sib txawv heev.
