Nruab nrab ntawm 500 ℃ thiab 200 ℃, 1.5mm-tuab tshav kub-insulating lev txuas ntxiv ua haujlwm rau 20 feeb yam tsis muaj ntxhiab tsw.
Cov khoom tseem ceeb ntawm no tshav kub-insulating lev yogairgel, lub npe hu ua "tus huab tais ntawm cov rwb thaiv tsev kub", lub npe hu ua "cov khoom siv ntau yam khoom siv tshiab uas tuaj yeem hloov tau lub ntiaj teb", yog lub hom phiaj thoob ntiaj teb tsom rau thaj chaw thaj tsam ntawm kev sib tw. Cov khoom no muaj cov thermal conductivity tsawg, kub tsis kam, kev siv ntau yam, feem ntau yog siv hauv kev lag luam aerospace, aircraft thiab nkoj, high-speed rail, tshiab zog tsheb, kev tsim kho kev lag luam thiab kev lag luam pipeline rwb thaiv tsev thiab lwm yam teb.
Muaj peb yam kev ntsuam xyuas tseem ceeb rauairgelnyob rau hauv kev ua lag luam: pH stability, nruam thermal rwb thaiv tsev thiab nruam hydrophobicity. Tam sim no, tus nqi pH ntawm cov khoom tsim airgel yog stabilized ntawm 7, uas tsis corrosive rau hlau los yog raw cov ntaub ntawv. Hais txog cov cuab yeej adiabatic tas li, tom qab siv ntau xyoo, kev ua haujlwm ntawm cov khoom yuav tsis raug txo los ntawm ntau dua 10%. Piv txwv li, nyob rau hauv lub 650 ℃ kub ib puag ncig, ib xyoo puag ncig uninterrupted siv, yuav kav 20 xyoo. Sustained hydrophobicity ntawm 99.5%.
Airgel cov khoom, ntau yam ntawm cov ntaub ntawv yooj yim, los ntawm kev siv ntauiav fiber mats, txuas mus rau basalt, siab silica, alumina, thiab lwm yam, cov khoom siv tuaj yeem siv los qhwv qhov kub qis tshaj ntawm rho tawm 200 ° C LNG pipeline, kuj tuaj yeem siv rau qhov sov sov ntawm ntau tshaj ib txhiab degrees Celsius supersonic aircraft engine rwb thaiv tsev, tab sis kuj tuaj yeem siv rau hauv lub tshuab nqus tsev.
Nrog rau qhov muaj koob meej ntawm cov tsheb tshiab lub zog, nws qhib qhov chaw rau kev lag luam thermal pad. Tsuas yog 126 pieces ntawmairgel, lub tshav kub-insulating kev nyab xeeb lev tuaj yeem tsim los tiv thaiv thermal khiav thiab hluav taws kub hauv cov roj teeb, tawm hauv lub sijhawm muaj txiaj ntsig rau cov neeg siv kom dim.
