Cov ntaub ntawv tshiab series - pom lub zog loj ntawm airgel
Apr 04, 2018
Aerogel, tseem hu ua xerogel, tseem hu ua cov pa luam yeeb xiav lossis cov pa taws khov, muaj cov yam ntxwv ntawm qhov hnyav ultra-lub teeb, tsis tshua muaj thermal conductivity, siab thermal stability, siab adsorption, siab zog nqus, suab rwb thaiv tsev, thiab lwm yam. zoo ductility, tab sis kuj muaj cov khoom zoo heev ntawm breathability, hluav taws tsis kam, roj thiab dej nqus.
Muaj ntau hom aerogels, xws li: silicon-based aerogels, carbon-based aerogels, sulfur-based aerogels, thiab lwm yam, uas feem ntau yog silica aerogel. Aerogels feem ntau yog muab faib ua plaub txoj hauv kev: los ntawm cov yam ntxwv zoo li, lawv tuaj yeem muab faib ua thaiv, hmoov thiab zaj duab xis aerogels; los ntawm txoj kev npaj, lawv tuaj yeem muab faib ua aerogels, xerogels thiab cryogels; los ntawm qhov sib txawv Lub microstructure tuaj yeem muab faib ua microporous, mesoporous thiab mixed-porous aerogels. Aerogels kuj yog cov khib nyiab tsawg tshaj plaws hauv lub ntiaj teb thiab tau suav nrog hauv Guinness Phau Ntawv Cov Ntaub Ntawv Ntiaj Teb uas yog cov khoom siv hluav taws xob tshaj plaws. Txij li ntau tshaj 80 feem pua ntawm airgel yog huab cua, nws muaj kev ua tau zoo hauv thermal rwb thaiv tsev.
Cov khoom tam sim no ntawm airgel feem ntau suav nrog kev xav, pawg thawj coj saib, ntaub, ntawv, granule, hmoov thiab tshwj xeeb-zoo li tus, ntawm cov khoom, feem ntau ntawm cov khoom yog airgel khoom nrog thermal rwb thaiv tsev muaj nuj nqi. Nrog rau cov khoom zoo tshaj plaws, cov kev tshawb fawb ntawm aerogels hauv kev tshawb fawb kev tshawb fawb txuas ntxiv nthuav dav. Raws li qhov tshwm sim, tus naj npawb ntawm cov teeb meem ua tiav ntawm kev siv tswv yim tau maj mam nce. Nws muaj kev ua tau zoo heev hauv kev ua tub rog thiab pej xeem, thiab siv ntau yam lag luam. Ua zoo.
