Airgel fiberglass xav yog silica airgel composite thermal rwb thaiv tsev cov khoom siv iav koob xav tau raws li lub substrate. Cov yam ntxwv thiab kev ua tau zoo ntawm microstructure ntawm airgel iav fiber lev feem ntau tshwm sim hauv cov khoom sib xyaw airgel agglomerate uas tsim los ntawm kev sib xyaw ntawm fiber ntau substrate thiab silica aerogel, embedded nyob rau hauv ib tug loj tus naj npawb ntawm micrometers nrog fiber ntau li cov pob txha. Nyob rau hauv cov pores loj dua, qhov tseeb qhov ceev yog 0.12 ~ 0.24g, thermal conductivity yog qis dua 0.025 W / m·K, lub zog compressive ntau dua 2mPa, qhov ntsuas kub yog -200 ~ 1000 ℃, thickness yog 3 hli, 6 hli, Nws yog 105 hli nyob rau hauv qhov dav ntawm 4 meters, 1.

Airgel fiberglass lev muaj cov yam ntxwv ntawm softness, yooj yim txiav, tsawg ntom, inorganic hluav taws tsis kam, tag nrho hydrophobicity, thiab ib puag ncig tiv thaiv. Nws tuaj yeem hloov cov khoom siv iav fiber ntau, cov khoom lag luam asbestos, cov khoom siv txhuas silicate thiab cov khoom siv thermal rwb thaiv tsev uas tsis zoo thermal rwb thaiv tsev. Nws yog tsuas yog siv nyob rau hauv industrial pipelines, cia tso tsheb hlau luam, industrial furnace lub cev, fais fab nroj tsuag, cawm cabins, warship bulkheads, ncaj qha faus pipelines, detachable thermal rwb thaiv tsev lub tes tsho, high-temperature chav pipelines, cov khoom siv hauv tsev, hlau thiab hlau smelting non-ferrous hlau thiab lwm yam thermal rwb thaiv tsev teb.

Daim ntawv thov ib puag ncig ntawm cov raj xa dej rwb thaiv tsev yog qhov nyuaj, nrog rau cov rwb thaiv tsev sab hauv, rwb thaiv tsev sab nraum zoov, thiab cov hluav taws xob faus ncaj qha. Piv nrog rau cov rwb thaiv tsev sab hauv thiab sab nraum zoov, kev siv airgel iav fiber lev cov ntaub ntawv nyob rau hauv ncaj qha faus pipeline rwb thaiv tsev hais txog qhov txawv txawv nta ntawm aerogel. Ua ntej ntawm tag nrho cov, lub hydrophobicity ntawm lub airgel xav tau yuav ua rau cov yeeb nkab rwb thaiv tsev txheej waterproof, thiab tiv thaiv qhov txo ntawm rwb thaiv tsev kev ua tau zoo tshwm sim los ntawm noo noo ntawm rwb thaiv tsev txheej. Tsis tas li ntawd, hydrophobicity kuj tseem muaj lub luag haujlwm tseem ceeb, uas yog los tiv thaiv condensation los ntawm qhov sib txawv ntawm qhov kub thiab txias. Lub porosity tso cai rau cov dej ntws tawm hauv daim ntawv ntawm cov dej vapor kom cov txheej rwb thaiv tsev qhuav. Raws li kev tiv thaiv corrosion thiab hluav taws-resistant khoom ntawm cov tsoos inorganic fibers, airgel iav fiber mats yog tag nrho nruab. Airgel iav fiber ntau yuav ua rau qhov chaw rwb thaiv tsev me me, vim tias airgel xav tau zoo thermal conductivity, yog li thaum tib lub rwb thaiv tsev ua tiav, lub thickness los yog qhov chaw ntawm lub airgel xav rwb thaiv tsev txheej me me, uas yog tsim rau faus ncaj qha. Nyob rau hauv cov nqe lus ntawm pipeline rwb thaiv tsev engineering, kev siv ntawm airgel xav kom ua tau zoo tib yam rwb thaiv tsev nyhuv yuav txo tau lub thickness ntawm rwb thaiv tsev txheej, uas txhais tau hais tias tus nqi ntawm lub ntiaj teb ua hauj lwm thiab lub sij hawm ntawm kev tsim kho yog luv luv, thiab tus nqi ntawm ob qhov kev txo nqi tuaj yeem cuam tshuam tag nrho kev siv aerogel. Felt yog siv los ua cov khoom siv rwb thaiv tsev los hloov cov nqi ntawm cov khoom siv rwb thaiv tsev ib txwm muaj.

Qhov yooj yim ntawm kev tsim kho ntawm airgel fiber ntau tuaj yeem txhim kho kev ua haujlwm ntawm kev tsim kho. Tom qab lub airgel xav tau txiav mus rau hauv ib qho me me, nws yuav ib txwm dov mus rau ib qho degree. Rau cov yeeb nkab rwb thaiv tsev, lub airgel xav tau txiav thiab muab tso ncaj qha rau ntawm cov yeeb nkab. Nws tuaj yeem ntsia tau thiab ruaj khov, thiab cov airgel xav tau yog lub teeb, muaj qee qhov hardness, thiab muaj qee qhov kev hloov pauv, tsis yooj yim tawg, thiab yooj yim heev rau txiav. Piv nrog rau kev tsim cov khoom siv rwb thaiv tsev ib txwm muaj, kev tsim kho kev ua tau zoo tuaj yeem nce ntau dua 30%, thiab nws kuj tsis txhob txhawj txog kev kho tom qab siv cov khoom siv rwb thaiv tsev ib txwm muaj.
