Airgel fiberglass felt yog cov khoom siv rwb thaiv tsev thermal silica aerogel siv cov iav koob felt ua lub substrate. Cov yam ntxwv thiab kev ua tau zoo ntawm cov qauv me me ntawm airgel iav fiber lev feem ntau pom tseeb hauv cov khoom sib xyaw ua ke aerogel agglomerate tsim los ntawm kev sib xyaw ua ke ntawm fiber substrate thiab silica aerogel, muab tso rau hauv ntau lub micrometers nrog cov khoom siv fiber ua pob txha. Hauv cov qhov loj dua, qhov ceev tiag tiag yog 0.12 ~ 0.24g, cov thermal conductivity qis dua 0.025 W / m · K, lub zog compressive ntau dua 2mPa, qhov kub thiab txias siv tau yog -200 ~ 1000 ℃, qhov tuab yog 3 hli, 6 hli, Nws yog 10 hli loj, 1.5 meters dav, thiab 40 txog 60 meters ntev.

Airgel fiberglass lev muaj cov yam ntxwv ntawm kev mos mos, yooj yim txiav, qhov ceev qis, tsis muaj hluav taws kub, tag nrho hydrophobicity, thiab kev tiv thaiv ib puag ncig. Nws tuaj yeem hloov cov khoom siv iav fiber, cov khoom asbestos, cov khoom txhuas silicate thiab cov ntaub ntawv rwb thaiv tsev thermal ib txwm muaj nrog cov khoom rwb thaiv tsev thermal tsis zoo. Nws feem ntau yog siv Nws yog siv rau hauv cov kav dej kev lag luam, cov tso tsheb cia khoom, cov chaw ua haujlwm rauv taws, cov chaw tsim hluav taws xob, cov chaw cawm siav, cov nkoj tub rog bulkheads, cov kav dej faus ncaj qha, cov tes tsho rwb thaiv tsev thermal detachable, cov kav dej kub kub, cov khoom siv hauv tsev, hlau thiab hlau smelting cov hlau tsis yog ferrous thiab lwm yam rwb thaiv tsev thermal thiab cov teb refractory.

Qhov chaw siv ntawm cov kav dej rwb thaiv tsev yog qhov nyuaj heev, suav nrog kev rwb thaiv tsev sab hauv tsev, kev rwb thaiv tsev sab nraum zoov, thiab kev rwb thaiv tsev ncaj qha. Piv nrog rau kev rwb thaiv tsev sab hauv tsev thiab sab nraum zoov, kev siv cov khoom siv aerogel iav fiber lev hauv kev rwb thaiv tsev ncaj qha qhia txog cov yam ntxwv tshwj xeeb ntawm aerogel. Ua ntej tshaj plaws, qhov hydrophobicity ntawm aerogel xav tuaj yeem ua rau cov kav dej rwb thaiv tsev txheej tsis muaj dej, thiab tiv thaiv kev txo qis ntawm kev ua haujlwm rwb thaiv tsev los ntawm cov dej noo ntawm cov txheej rwb thaiv tsev. Tsis tas li ntawd, qhov hydrophobicity kuj muaj lub luag haujlwm tseem ceeb heev, uas yog los tiv thaiv kev sib xyaw ua ke los ntawm qhov sib txawv ntawm qhov kub thiab txias. Qhov porosity tso cai rau cov dej noo kom raug tso tawm hauv daim ntawv ntawm cov pa dej kom cov txheej rwb thaiv tsev qhuav. Raws li cov khoom tiv thaiv xeb thiab hluav taws-resistant ntawm cov fibers inorganic ib txwm muaj, aerogel iav fiber mats tau nruab nrog tag nrho. Airgel iav fiber xav yuav ua rau qhov chaw rwb thaiv tsev me dua, vim tias aerogel xav muaj kev ua haujlwm thermal zoo, yog li thaum cov nyhuv rwb thaiv tsev zoo ib yam, qhov tuab lossis qhov chaw ntawm aerogel xav txheej rwb thaiv tsev me dua, uas yog qhov tsim nyog dua rau kev faus ncaj qha. Hais txog kev tsim kho vaj tse rwb thaiv tsev, kev siv airgel xav kom ua tiav tib yam rwb thaiv tsev tuaj yeem txo qhov tuab ntawm cov txheej rwb thaiv tsev, uas txhais tau tias qhov ntau ntawm kev ua haujlwm hauv av thiab lub sijhawm tsim kho luv dua, thiab tus nqi ntawm ob qho kev txo qis no tuaj yeem them tag nrho kev siv airgel. Felt yog siv ua cov khoom siv rwb thaiv tsev los hloov tus nqi ntawm cov ntaub ntawv rwb thaiv tsev ib txwm muaj.

Qhov yooj yim ntawm kev tsim cov airgel fiber felt tuaj yeem txhim kho qhov ua tau zoo ntawm kev tsim kho. Tom qab cov airgel felt raug txiav rau hauv qee qhov loj me, nws yuav dov mus rau qee qib. Rau cov yeeb nkab rwb thaiv tsev, cov airgel felt raug txiav thiab muab tso ncaj qha rau ntawm cov yeeb nkab. Nws tuaj yeem ntsia thiab kho, thiab cov airgel felt yog lub teeb, muaj qee qhov nyuaj, thiab muaj qee qhov kev ywj pheej, tsis yooj yim tawg, thiab yooj yim heev rau txiav. Piv nrog rau kev tsim cov ntaub ntawv rwb thaiv tsev ib txwm muaj, kev ua haujlwm ntawm kev tsim kho tuaj yeem nce ntxiv ntau dua 30%, thiab nws kuj zam kev txhawj xeeb txog kev saib xyuas tom qab siv cov ntaub ntawv rwb thaiv tsev ib txwm muaj.
