Cov kauj ruam tsim khoom rau fiberglass airgel stitched combo lev

Aerogels muaj qhov ceev tsawg heev, thaj chaw tshwj xeeb thiab porosity siab, uas qhia txog cov khoom siv optical, thermal, acoustic, thiab hluav taws xob tshwj xeeb, uas yuav muaj kev cia siab dav hauv ntau qhov chaw. Tam sim no, cov khoom lag luam airgel zoo tshaj plaws hauv ntiaj teb yog cov khoom zoo li ua los ntawm SiO₂ airgel thiab iav fiber composite.
FiberglassCov ntaub pua plag airgel xaws ua ke feem ntau yog cov khoom siv rwb thaiv tsev ua los ntawm airgel thiab iav fiber sib xyaw. Nws tsis tsuas yog khaws cov yam ntxwv ntawm kev ua kom sov qis ntawm airgel, tab sis kuj muaj cov yam ntxwv ntawm kev ywj pheej thiab lub zog tensile siab, thiab yooj yim rau kev tsim kho. Piv nrog cov ntaub ntawv rwb thaiv tsev ib txwm muaj, iav fiber airgel muaj ntau qhov zoo ntawm kev ua kom sov, cov khoom siv kho tshuab, kev tiv thaiv dej, thiab kev tiv thaiv hluav taws.
Nws feem ntau muaj cov teebmeem ntawm cov nplaim taws retardant, thermal rwb thaiv tsev, thermal rwb thaiv tsev, suab rwb thaiv tsev, poob siab nqus, thiab lwm yam. Nws tuaj yeem siv ua lub substrate rau thermal rwb thaiv tsev ntawm cov tsheb fais fab tshiab, lub qhov rooj tsheb vaj huam sib luag qab nthab cov ntaub ntawv, kho kom zoo nkauj sab hauv cov phaj kho kom zoo nkauj yooj yim, kev tsim kho, kev lag luam thiab lwm yam thermal rwb thaiv tsev, suab-nqus thiab cua sov rwb thaiv tsev cov ntaub ntawv, iav fiber reinforced yas composite cov ntaub ntawv, kev lag luam siab-kub lim cov ntaub ntawv, thiab lwm yam. Substrate.
Cov txheej txheem npaj ntawm SiO₂ aerogel composite feem ntau suav nrog txoj kev nyob rau hauv situ, txoj kev soaking, txoj kev tshuaj lom neeg pa permeation, txoj kev molding, thiab lwm yam. Ntawm lawv, txoj kev nyob rau hauv situ thiab txoj kev molding feem ntau yog siv los npaj cov khoom siv fiber-reinforced SiO₂ aerogel composite.
Cov txheej txheem tsim khoom ntawmfiberglass airgel levfeem ntau suav nrog cov kauj ruam hauv qab no:
① Kev kho ua ntej ntawm cov iav fiber: Cov kauj ruam ua ntej ntawm kev ntxuav thiab ziab cov iav fiber kom ntseeg tau tias qhov zoo thiab huv ntawm cov fiber.
② Kev npaj cov aerogel sol: Cov kauj ruam rau kev npaj cov airgel sol zoo ib yam li cov aerogel felt ib txwm muaj, piv txwv li cov tshuaj silicon-derived (xws li silica) yog sib xyaw nrog cov kuab tshuaj thiab cua sov kom tsim tau cov sol sib xws.
③ Txheej fiber: Cov ntaub iav fiber lossis xov paj yog infiltrated thiab coated hauv lub sol, yog li ntawd lub fiber yog nyob rau hauv tag nrho kev sib cuag nrog lub aerogel sol.
④ Gel tsim: Tom qab cov fiber yog coated, nws yog gelatinized. Txoj kev ntawm gelation siv tau cua sov, pressurization, lossis tshuaj crosslinking cov neeg sawv cev los txhawb kev tsim ntawm cov qauv gel khoom ntawm airgel.
⑤ Kev tshem tawm cov kuab tshuaj: Zoo ib yam li cov txheej txheem tsim khoom ntawm cov airgel dav dav, cov gel yuav tsum tau yaj kom tsuas yog cov qauv aerogel khov kho nyob hauv cov fiber.
⑥ Kev kho cua sov: Lubfiberglass airgel levtom qab desolvation yog cua sov kho kom txhim kho nws qhov ruaj khov thiab cov khoom siv kho tshuab. Qhov kub thiab lub sijhawm ntawm kev kho cua sov tuaj yeem hloov kho raws li qhov xav tau tshwj xeeb.
⑦ Txiav/ua: Cov iav fiber airgel uas xav tias tom qab kev kho cua sov tuaj yeem txiav thiab ua kom tau txais cov duab thiab qhov loj me uas xav tau.
⑧ Kev kho qhov chaw (xaiv tau): Raws li qhov xav tau, qhov chaw ntawm fiberglass airgel lev tuaj yeem kho ntxiv, xws li txheej, npog lossis ua haujlwm, kom tau raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb.
