Cov kauj ruam ntau lawm rau fiberglass airgel stitched combo lev

Aerogels muaj qhov ntom ntom tsawg kawg, muaj cov khoom lag luam zoo nkauj, cov khoom lag luam hluav taws xob, thiab cov khoom siv hluav taws xob zoo nkauj, cov khoom siv hluav taws xob ua tau zoo li cov khoom siv hluav taws xob ua cov khoom lag luam zoo li cov khoom siv.
Fiberglassairgel stitched combo lev feem ntau yog cov khoom siv rwb thaiv tsev ua los ntawm airgel thiab iav fiber ntau sib xyaw. Nws tsis tsuas yog khaws cov yam ntxwv ntawm cov thermal conductivity tsawg ntawm aerogel, tab sis kuj muaj cov yam ntxwv ntawm kev yooj yim thiab lub zog tensile siab, thiab yooj yim rau kev tsim.Piv nrog cov khoom siv rwb thaiv tsev, iav fiber ntau airgel xav tau ntau yam zoo ntawm thermal conductivity, mechanical zog, dej tsis kam, thiab hluav taws kub.
Nws tsuas yog muaj qhov cuam tshuam ntawm nplaim hluav taws, thermal rwb thaiv tsev, thermal rwb thaiv tsev, suab rwb thaiv tsev, kev poob siab, thiab lwm yam. Nws tuaj yeem siv los ua lub substrate rau thermal rwb thaiv tsev ntawm lub zog tshiab, tsheb qhov rooj vaj huam sib luag qab nthab cov ntaub ntawv, sab hauv kho kom zoo nkauj daim hlau, kev tsim kho, kev lag luam thiab lwm yam thermal rwb thaiv tsev, suab-absorbing thiab tshav kub-insulating cov ntaub ntawv, iav fiber ntau cov ntaub ntawv, thiab lwm yam. Substrate.
Cov kev npaj ntawm SiO₂ airgel composite cov ntaub ntawv feem ntau muaj xws li nyob rau hauv situ txoj kev, txoj kev soaking, tshuaj vapor permeation txoj kev, molding txoj kev, thiab lwm yam.
Cov txheej txheem ntau lawm ntawmfiberglass airgel levFeem ntau suav nrog cov kauj ruam hauv qab no:
① Cov iav fiber ntau pretreatment: Cov kauj ruam ua ntej ntawm kev ntxuav thiab ziab cov iav fiber ntau kom ntseeg tau qhov zoo thiab purity ntawm fiber ntau.
② Kev npaj ntawm airgel sol: Cov kauj ruam rau kev npaj airgel sol zoo ib yam li zoo tib yam airgel xav, piv txwv li silicon-derived compounds (xws li silica) yog tov nrog ib tug hnyav thiab rhuab los ua ib tug uniform sol.
③ Txheej fiber ntau: Cov iav fiber ntau daim ntaub los yog xov paj yog infiltrated thiab coated nyob rau hauv lub sol, kom cov fiber nyob rau hauv tag nrho kev sib cuag nrog lub airgel sol.
④ Gel tsim: Tom qab cov fiber ntau coated, nws yog gelatinized.Cov txheej txheem ntawm gelation siv tau cua sov, pressurization, los yog tshuaj crosslinking agents los txhawb kev tsim cov khoom gel qauv ntawm aerogel.
⑤ Kev tshem tawm cov kuab tshuaj: Zoo ib yam li cov txheej txheem tsim tawm ntawm kev xav dav dav, cov gel yuav tsum tau muab tshem tawm kom tsuas yog cov khoom siv airgel nkaus xwb hauv cov fiber ntau.
⑥ Kev kho cua sov: Lubfiberglass airgel levtom qab desolvation yog kho cua sov los txhim kho nws cov stability thiab mechanical zog.Qhov kub thiab lub sij hawm ntawm kev kho cua sov tuaj yeem hloov kho raws li cov kev cai tshwj xeeb.
⑦ Txiav / sib sau: Cov iav fiber ntau airgel xav tau tom qab kev kho cua sov tuaj yeem txiav thiab tsim kom tau txais cov duab thiab qhov loj me.
⑧ Kev kho deg (yeem): Raws li kev xav tau, qhov chaw ntawm fiberglass airgel lev tuaj yeem kho ntxiv, xws li txheej, npog lossis ua haujlwm, kom tau raws li cov kev xav tau tshwj xeeb.
