microporous rwb thaiv tsev board, uas yog, nrog nanoparticles raws li cov tub ntxhais, yog tsim los ntawm refractory khoom hais, binders, thiab lwm yam. los ua ib tug nano-structure matrix. Cov khoom ntawm lub cev thiab tshuaj lom neeg ntawm ib qho me me ntawm nano-structure matrix dhau los ua qhov tseem ceeb hauv kev txiav txim siab kev ua haujlwm ntawm tag nrho cov khoom siv refractory. Lub thermal expansion thiab contraction sai los ntawm kev cuam tshuam tuaj yeem tiv thaiv qhov tsis sib xws ntawm thermal kev ntxhov siab hauv cov khoom siv refractory, yog li txhim kho cov spilling tsis kam, corrosion kuj thiab oxidation tsis kam ntawm cov khoom refractory.
Cov yam ntxwv ntawm microporous rwb thaiv tsev board
1. Tiv thaiv cov thermal txav ntawm cov roj molecules.
Raws li txoj kev xav ntawm molecular thermal motion, lub tshav kub hloov ntawm cov roj yog tsuas yog los ntawm kev sib tsoo ntawm cov molecules nrog ntau dua tshaj tawm nyob rau sab kub siab rau molecules nrog qis tshaj tawm nyob rau hauv qis kub sab, thiab maj mam hloov cov cua sov. Yog hais tias ib tug series ntawm cov teeb meem yog tsim nyob rau hauv cov kev taw qhia ntawm qhov kub thiab txias gradient, thiab qhov kev ncua deb ntawm lub barriers yog tsawg tshaj li qhov nruab nrab txoj kev ntawm cov pa roj molecules, thiab cov barriers raug kaw thiab ze rau lub tshuab nqus tsev qhov, lub thermal txav ntawm cov roj molecules yuav. tiv thaiv tau zoo.
2. Txo cov cua sov ua kom sov.
Lub thermal conductivity ntawm nanoporous silicon hmoov yog {{0}}}016~0.024 w/mk, thiab lub microporous rwb thaiv tsev board yog ib tug super thermal rwb thaiv tsev cov ntaub ntawv uas kuj tsis tshua muaj. thermal conductivity. Aluminium ntawv ci nrog lub thickness ntawm tsuas yog 6 ~ 10 nanometers muaj thermal conductivity ntawm 0.038 mus rau 0.042w / mk, uas yog ib tug zoo heev tshav kub insulating khoom.
3. Thaiv cov hluav taws xob hluav taws xob.
Lub microporous rwb thaiv tsev board yog tsim los ntawm nano-silica thiab txhuas ntawv ci. Cov txheej txheej aluminium ntawv ci ua lub luag haujlwm ntawm kev xav txog hluav taws xob hluav taws xob, thiab qhov kev xav tau siab dua 87 feem pua. Cov nyhuv ntawm tshav kub tawg.
