Airgel, feem ntau hu ua "cua cua," yog paub rau nws ultra - porosity, thiab zoo heev thermal rwb thaiv tsev zog. Xyoo dhau los, cov khoom siv tshawb fawb tau hloov pauv hloov pauv loj dua rau cov ntaub ntawv sib xyaw rau cov ntaub ntawv hauv cov khoom siv hauv cov khoom siv hauv cov khoom siv hauv cov duab Qhov kev txhawj xeeb tseem ceeb hauv cov ntaub no yog yooj yim: Lawv puas tuaj yeem tswj cov rwb thaiv tsev thaum tau hnav, thiab siv neeg ruaj khov? Tsab ntawv no tshawb nrhiav cov qauv, kev ntsuas yooj yim, kev tsim khoom, siv cov ncauj lus siv, thiab yav tom ntej cov qauv ntawm cov pa roj cargel composite Fabrics.
Cov qauv yooj yim ntawm Airgel Composite Fabrics
Airgel Composite cov ntaub feem ntau muaj ntawm ob qho tseem ceeb: txheej airgel txheej thiab textile substrate. Lub airgel txheej muab cov rwb thaiv tsev thermal thiab kev ua tau zoo tshaj plaws, thaum lub textile acttrate pab txhawb kev kho tshuab thiab yooj. Raws li cov hom airgel thiab txoj kev koom ua ke, cov ntaub ntawv sib xws xws li:
Airgel Pam plam phibsab:Cov pam airgel yog cov qhaub cij ntawm ob textile txheej thiab tsau ntawm cov cua sov nias lossis cov nplaum. Thaum daim pam ib leeg yog nkaab
Airgel -} Coated ntaub:Airgel slurry yog txau los yog dipped mus rau cov ntaub saum npoo av, sib sau ib txheej insulating txheej. Cov ntaub tau muab cov ntaub nyias nyias yog qhov yooj yim tab sis muaj tsawg dua rwb thaiv tsev tuab, tsim nyog rau kev siv nrog cov cua sov thermal.
Airgel fiber ntau comprosite ntaub:Airgel hais tau sib xyaw nrog siab - lub zog wibers los tsim cov yarns, uas yog tom qab ntawd woven rau hauv ntaub. Airgel muaj nyob rau hauv micron - dized daim ntawv nyob rau hauv fiber network, muab cov zog hloov kho kom haum thiab tensile {3} Ib thaj chaw tsom xam nyob hauv kev tshawb fawb tam sim no.
Lub hom phiaj ntawm cov qauv no yog kom kov yeej lub ntsej muag brittleness ntawm airgel, uas ua rau cov foldable thiab bendable Foom thiab bendable Foom haum rau cov ntoo thiab cov chaw sib zog.
Kev ntsuas cov ntaub npuag hloov tau
Yooj yooj yim rau cov pa Airgel Composite Fabrics yog feem ntau ntsuas siv ntau qhov ntsuas:
Dabtsi yog khoov Tiffness:Ntsuas kev tawm tsam rau khoov hauv qab. Txo khoov pob tw teeb meem qhia tias softer, cov ntaub tau yooj yim dua.
Tensile lub zog thiab elongation:Muaj peev xwm tswj cov qauv thiab kev ncaj ncees nyob rau hauv ncab, tseem ceeb rau cov khaub ncaws sab nraum zoov lossis cov khaub ncaws tiv thaiv uas tau ua kom txav lossis kev ntxhov siab.
Fold Durability:Xyaum ua kom muaj kev thaiv kev ua haujlwm thiab cov qauv nyob hauv qab tom qab rov muab dua lossis dov. Saj zawg zog cov ntaub tuaj yeem tiv thaiv ntau pua ntawm cov quav tsis muaj kev ua kom tsis muaj kev cuam tshuam.
Thickness - rau - Qhov hnyav nyhav:Thinner Airgel Composite Fabrics feem ntau nthuav tawm kev hloov kho tau zoo thaum tseem insulating zoo.
Kev tshawb fawb qhia tau tias cov pam vov pam vov ua ke nrog cov pa roj carii ntawm 2-5 mm thiab cloft {} txaus rau cov khaub ncaws hnav thiab cov ntawv thov aerospace.
Kev tsim kho cov txheej txheem thiab lawv cov kev cuam tshuam rau kev hloov tau
Yooj nyob ntawm cov txheej txheem fabrication. Cov Ntsiab Lus Tseem Ceeb muaj:
Airgel particle loj thiab faib:Me me, tusyees faib ua kom tsawg dua brittleness thiab txhim kho txhua qhov hloov tag nrho. Cov khoom loj yog tus nquag ntes thaum khoov thaum khoov.
Textile Xaiv thiab Weave Hom:Knitted ntaub los yog elastic fibers yog softer thiab zoo dua haum rau kev ua raws lub cev lossis cov chaw sib xyaw ua kom nruj dua cov ntaub qhwv.
Composite Qauv:Thaum tshav kub kub nce rwb thaiv tsev rwb thaiv tsev ua tau zoo tab sis yuav txo qis yooj yim, whereas dipping kev muag khoom tab sis me ntsis qis qis thermal ua tau. Yuav tsum muaj daim ntawv thov kev xaiv.
Nto Kho:Kev hloov chaw lim dej lossis nano {-}}}}}}}}}}}}}}}}}}}}}} ure txhim kho kev ua tau zoo thiab txhim kho cov nplaum ntawm airgel thiab fibers.
Kev lag luam kev lag luam qhia tau hais tias 3-5 hli tuab watgel pam ua tiav tau qhov sib npaug ntawm cov hnab looj tes ua kom zoo tshaj plaws rau hnab looj tes, khau khiab, lossis lub teeb yuag.
Cov Ntawv Thov Siv
Cov Khaub Ncaws Sab Nraud Thiab Cov Iav
Airgel Composite cov ntaub yog siv dav hauv cov tsho ntxhua khaub ncaws, nce khaub ncaws, hnab looj tes, thiab khau khiab. Piv nrog tso ib txwm los yog rwb thaiv tsev polyester, airgel ntaub yog sib dua, sov, thiab ntau dua {1} tiv taus. Piv txwv li, Ncov Qaum Ntuj Ncaws Pob Ua Haujlwm Tshav Dav Hlau tuaj yeem muab ntau dua 30% qhov sov ntxiv thaum txo qhov hnyav, ua kom txav chaw rau kev tshawb nrhiav.
Aerospace Cov Ntawv Thov
Saj zawg zog, insulating airgel ntaub yog siv rau lub tshuab rwb thaiv tsev cav, cov chaw sib tw txheej, thiab foob pob ua ntxaij vab tshaus. Yooj yim ua kom muaj kev sib haum xeeb kom haum rau cov kab nkhaus ua rau muaj kev ntseeg siab nyob rau hauv kev co siab. NASA kev sim qhia qhov chaw sib haum nrog cov pa ua kom haum rau 40% sib zog dua li kev rwb thaiv tsev thaum xa cov kev ua tau zoo tshaj plaws.
TSEV THIAB MUAJ CAI RUAJ
Hauv kev tsim kho thiab kev lag luam, hloov kho cov pa hluav taws xob kho rau cov raj dej rwb thaiv tsev, boilers, thiab hluav taws kub {{} {} {tsis tiv taus khaub ncaws. Tsis zoo li cov panels rigid, lawv tuaj yeem khoov ib ncig thaj chaw tsis xwm yeem, txuag chaw thiab txo qhov chaw kub. Hauv kev tiv thaiv cov khaub ncaws, lawv muab kev nyab xeeb ntawm cua sov hauv high- qhov chaw ib puag ncig thaum tseem muaj kev hnav khaub ncaws zoo.
Cov Ntawv Thov Tawm
Nrog rau sawv ntawm cov khoom siv hluav taws xob hloov thiab cov khoom siv hnav tau zoo, cov tshuab hluav taws xob muaj peev xwm nyob hauv kev tiv thaiv roj teeb, thiab cov ntaub npog tiv thaiv. Lawv cov kev sib xyaw ua ke ntawm lub teeb ci, hloov tau yooj yim, thiab kev rwb thaiv tsev thermal ua rau lawv haum rau cov ntawv thov siab.
Kev kuaj cov qauv thiab kev tswjhwm zoo
Rau kev ua lag luam kev coj ua, kev sim ua ke thiab cov qauv tseem ceeb heev. Cov kev ntsuas raug xws li thermal conductivity (λ - tus nqi) nyob rau hauv compression, hydrostatic tsis kam rau cov coivit cov tshuaj, thiab cyclic sib xyaws / nkees sim. Tuam txhab uas ua haujlwm nrog cov tshuab hluav taws xob ua haujlwm feem ntau yuav tsum muaj:
Rov ua cov ntaub ntawv ua haujlwm thermal raws li qhov muaj tiag compression thiab khoov cov xwm txheej.Rwb thaiv tsev feem ntau hloov pauv thaum cov ntaub yog compressed (piv txwv li, hauv lub tsho hnab ris), yog li kev sim yuav tsum muaj kev sib tw kawg- siv.
Ntxuav thiab hnav kev sim ua tsis ntevRau cov ntawv thov hnav, vim tias kev tsim txiaj tuaj yeem txwv cov txheej txheej lossis cov nplaum ua ke.
Hluav Taws thiab Tshuaj Tsis Zooqhov twg tsim nyog (piv txwv li, kev lag luam ppe lossis aerospace).
Kev ntsuas cov khoom lag luam loj heev nyob rau hauv ntau production {{} kev ntsuas tuab, thiab ua kom zoo tshaj plaws rau cov neeg lag luam B2b
Saib xyuas, txij nkawm, thiab xaus {{0} Tus neeg siv cov lus qhia
Txhawm rau ua kom muaj kev ua haujlwm ntau lub neej, xaus -}}} cov neeg siv yuav tsum ua raws cov lus qhia yooj yim:
