Nruab nrab ntawm 500 ℃ thiab 200 ℃, daim lev rwb thaiv cua sov uas tuab 1.5 hli txuas ntxiv ua haujlwm tau 20 feeb yam tsis muaj ntxhiab tsw.
Cov khoom siv tseem ceeb ntawm daim lev rwb thaiv cua sov no yogairgel, hu ua "tus vaj ntxwv ntawm kev rwb thaiv tshav kub", hu ua "cov khoom siv tshiab uas muaj ntau yam ua haujlwm uas tuaj yeem hloov lub ntiaj teb", yog qhov kev tsom mus rau thoob ntiaj teb rau thaj chaw tseem ceeb. Cov khoom no muaj cov thermal conductivity qis, tiv taus kub siab, ntau yam kev siv, feem ntau yog siv hauv kev lag luam aerospace, dav hlau thiab nkoj, tsheb ciav hlau ceev ceev, tsheb fais fab tshiab, kev lag luam tsim kho thiab kev rwb thaiv tshav kub hauv kev lag luam thiab lwm yam.
Muaj peb qho tseem ceeb ntawm kev ntsuam xyuas rauairgelnyob rau hauv kev ua lag luam: pH ruaj khov, kev rwb thaiv tsev thermal tas mus li thiab hydrophobicity tas mus li. Tam sim no, tus nqi pH ntawm cov khoom airgel tsim tawm tau ruaj khov ntawm 7, uas tsis yog corrosive rau cov hlau lossis cov ntaub ntawv raw. Hais txog cov khoom adiabatic tas mus li, tom qab ntau xyoo siv, kev ua tau zoo ntawm cov khoom yuav tsis raug txo ntau dua 10%. Piv txwv li, nyob rau hauv 650 ℃ kub ib puag ncig, kev siv tsis tu ncua thoob plaws hauv ib xyoos, tuaj yeem kav ntev li 20 xyoo. Hydrophobicity tas mus li ntawm 99.5%.
Cov khoom siv Aerogel, ntau yam khoom siv yooj yim, los ntawm cov khoom siv feem ntaucov ntaub pua plag iav, txuas ntxiv mus rau basalt, silica siab, alumina, thiab lwm yam, cov khoom siv tau los qhwv qhov kub qis tshaj plaws ntawm rho tawm 200 ° C LNG pipeline, kuj tseem siv tau rau kev sov tam sim ntawd ntawm ntau dua ib txhiab degrees Celsius supersonic aircraft engine rwb thaiv tsev, tab sis kuj siv tau rau hauv qhov chaw nqus tsev.
Nrog rau qhov nrov ntawm cov tsheb fais fab tshiab, nws qhib qhov chaw rau kev ua lag luam thermal pad. Tsuas yog 126 daim ntawmairgel, ib daim lev tiv thaiv cua sov tuaj yeem tsim los tiv thaiv kev khiav tawm ntawm cov roj teeb thiab hluav taws, tawm lub sijhawm muaj nqis rau cov neeg siv khiav dim.
