Felt ya Airgel fiberglass ndi chinthu chotenthetsera kutentha cha silica aerogel chomwe chimagwiritsa ntchito glass needled felt ngati substrate. Makhalidwe ndi magwiridwe antchito a microstructure ya matiresi a galasi la airgel amawonekera makamaka mu tinthu tating'onoting'ono ta airgel agglomerate tomwe timapangidwa ndi kuphatikiza kwa fiber substrate ndi silica aerogel, tomwe timayikidwa mu ma micrometer ambiri okhala ndi fiber ngati mafupa. M'ma pores akuluakulu, kuchuluka kwenikweni ndi 0.12 ~ 0.24g, kutentha kwa mpweya kumakhala kotsika kuposa 0.025 W/m·K, mphamvu yopondereza ndi yayikulu kuposa 2mPa, kutentha komwe kumagwiritsidwa ntchito ndi -200 ~ 1000℃, makulidwe ndi 3 mm, 6 mm, Ndi kukula kwa 10 mm, m'lifupi mamita 1.5, ndi kutalika mamita 40 mpaka 60.

Mphete ya Airgel fiberglass ili ndi mawonekedwe ofewa, osavuta kudula, ofooka, osagwirizana ndi moto, osagwirizana ndi madzi, komanso kuteteza chilengedwe. Imatha kusintha zinthu zagalasi, zinthu za asbestos, zinthu za aluminiyamu silicate ndi zinthu zachikhalidwe zotetezera kutentha zomwe zimakhala ndi mphamvu zochepa zotetezera kutentha. Imagwiritsidwa ntchito kwambiri m'mapaipi a mafakitale, matanki osungiramo zinthu, malo opangira ng'anjo ya mafakitale, malo opangira magetsi, nyumba zopulumutsira anthu, malo osungiramo sitima zankhondo, mapaipi obisika mwachindunji, manja oteteza kutentha omwe amatha kuchotsedwa, mapaipi a nthunzi yotentha kwambiri, zipangizo zapakhomo, zitsulo zopanda chitsulo zosungunulira zitsulo ndi zina zotetezera kutentha ndi minda yotsutsa.

Malo ogwiritsira ntchito poteteza mapaipi ndi ovuta, kuphatikizapo kutchinjiriza mkati, kutchinjiriza kunja, ndi kutchinjiriza mapaipi molunjika. Poyerekeza ndi kutchinjiriza mapaipi m'nyumba ndi kunja, kugwiritsa ntchito zinthu zopangira matiresi agalasi a airgel mu kutchinjiriza mapaipi molunjika kukuwonetsa mawonekedwe odabwitsa a airgel. Choyamba, kutchinjiriza kwa aerogel felt kungapangitse kuti chitoliro cha mapaipi chisalowe madzi, ndikuletsa kuchepa kwa magwiridwe antchito oteteza chifukwa cha chinyezi cha chitoliro. Kuphatikiza apo, kutchinjiriza kwa madzi kulinso ndi ntchito yofunika kwambiri, yomwe ndi kupewa kuzizira komwe kumachitika chifukwa cha kusiyana kwa kutentha. Kutupa kwa madzi kumalola chinyezi kutuluka mu mawonekedwe a nthunzi yamadzi kuti chitolirocho chikhale chouma. Ponena za mphamvu zotsutsana ndi dzimbiri komanso zosagwira moto za ulusi wachikhalidwe wosapangidwa, matiresi agalasi a airgel ali ndi zida zonse. Chitoliro chagalasi cha airgel chimapangitsa kuti malo otetezera kutentha akhale ochepa, chifukwa aerogel felt imakhala ndi kutentha kwabwino, kotero pamene zotsatira zomwezo za kutchinjiriza zapezeka, makulidwe kapena malo a chitoliro cha aerogel felt ndi ochepa, omwe ndi oyenera kwambiri kubisa mwachindunji. Ponena za uinjiniya woteteza mapaipi, kugwiritsa ntchito mpweya woteteza kuti ukhale ndi mphamvu yoteteza yomweyi kungachepetse makulidwe a mpweya woteteza, zomwe zikutanthauza kuti kuchuluka kwa ntchito ya nthaka ndi nthawi yomanga zimafupikitsidwa, ndipo mtengo wa kuchepetsa kumeneku kungathe kuchepetsa kugwiritsa ntchito mpweya woteteza. Felt imagwiritsidwa ntchito ngati chinthu chotetezera kuti ilowe m'malo mwa mtengo wa zipangizo zachikhalidwe zotetezera.

Kusavuta kwa kapangidwe ka ulusi wa aerogel kungathandize kukonza bwino ntchito yomanga. Pambuyo poti aerogel felt yadulidwa kukula kwinakwake, imapindika mwachibadwa kufika pamlingo winawake. Pa kutchinjiriza mapaipi, aerogel felt imadulidwa ndikuyikidwa mwachindunji pa chitoliro. Ikhoza kuyikidwa ndikukhazikika, ndipo aerogel felt ndi yopepuka, ili ndi kuuma kwinakwake, ndipo ili ndi kusinthasintha kwinakwake, sikophweka kuswa, ndipo ndi yosavuta kudula. Poyerekeza ndi kapangidwe ka zipangizo zotchinjiriza zachikhalidwe, mphamvu yomanga imatha kuwonjezeka ndi kupitirira 30%, ndipo imapewanso nkhawa ndi kugwiritsa ntchito zipangizo zotchinjiriza zachikhalidwe pambuyo pokonza.
