Airgel board yog cov khoom siv high-tech nrog cov khoom sib txawv. Nws yog ua los ntawm cov tub ntxhais qub ua tub ntxhais, muaj ultra-qes ultra, siab porosity thiab zoo heev thermal rwb thaiv tsev kev ua tau zoo. Tsis zoo li ib txwm kos los yog gel-zoo li cov ntaub ntawv, tus qauv ntawm cov txheej txheem airgel yog ib qho qauv zoo tshaj plaws thiab kev ua haujlwm zoo. Vim nws cov rwb thaiv tsev zoo heev, compression tsis kam thiab nplaim retardant muaj peev xwm, airgel board tau siv hauv kev txuag hluav taws xob, ib puag ncig thiab ib puag ncig tshwj xeeb. Kab lus no yuav ua rau cov yam ntxwv tob tob, thov teb thiab yav tom ntej kev txhim kho ntawm cov txiaj ntsig zoo dua cov qauv zoo thiab muaj peev xwm ntawm cov ntaub ntawv tshiab no.

1. Cov ntsiab lus yooj yim ntawm cov khoom siv Airgel
Airgel yog cov khoom siv ntxeem tau npaj los ntawm cov txheej txheem tshwj xeeb uas muaj ntom ntom ntom thiab siab porosity. Raws li cov lus txhais ntawm cov ntaub ntawv thoob ntiaj teb, Airgel yog "cov ntaub ntawv ntxeem tau uas khaws cov pob txha pob txha pob khaus los ntawm kev ziab scening". Nws cov yam ntxwv tseem ceeb yog tias nws cov pob txha pob txha khaws cov roj ntau ntawm cov pa roj, uas ua rau muaj huab cua muaj roj dog dig thiab cov pa thermal zoo heev. Tsis zoo li cov khoom siv viscous lossis colloidal tsis muaj adaesion lossis fluidity, yog li muaj qhov sib txawv hauv lub xeev thiab kev npaj ua haujlwm. Hydrogel thiab silica gel yog colloidal tshuaj tsim los ntawm kev sib txuas dej los yog lwm cov huab cua, thiab cov khoom siv kom qhuav, thiab khaws cov qauv sib xyaw, khoom siv network.
Txawm li cas los xij, hauv qee qhov kev lag luam, Airgel koom ua ke nrog cov nplaum ua ke los tsim cov khoom siv sib xyaw ua ke, uas yuav ua rau muaj kev tsis nkag siab ntawm lub zog ntawm Airgel. Qhov tseeb, ua cov khoom siv khov kho, airgel tsis muaj viscosity los yog adhesion ua haujlwm ntawm cov khoom siv colroidal. Nkag siab qhov no yog qhov tseem ceeb rau kev thov zoo dua thiab kev loj hlob ntawm airgel tshuab.
2. Kev txheeb xyuas ntawm cov khoom siv
Cov ntaub ntawv viscous yog cov khoom siv semi-cov khoom siv uas cia siab rau cov kev sib txuam cov zog los tswj cov fluidity. Cov khoom siv viscous suav nrog epoxy resins, lub siab-rhiab cov nplaum, thiab cov khoom siv siab, thiab muaj peev xwm deform thiab tswj hwm ib qho cim nyob rau sab nraud. Nws cov cim taw qhia tseem ceeb suav nrog viscosity, thixotropy, uas cuam tshuam rau kev ua tau zoo ntawm ntau lub peev xwm sib txawv nrog lwm cov ntaub ntawv. Cov yam ntxwv ua no ua rau cov khoom siv viscous feem ntau siv nyob rau hauv cov ntawv thov xws li sib khi, txheej thiab tsev ntaub.
Airgel yog cov khoom siv khov kho cov khoom siv tsis zoo thiab cov hluav taws xob zoo nkauj heev thiab cov khoom siv hluav taws xob. Piv txwv li, Nano-nplai qhib-pore qauv ntawm polyurethane-based airgel zoo txwv kev kub, ua rau nws cov khoom siv rwb ua kom sov. Txawm li cas los xij, tsis zoo li viscous cov ntaub ntawv, aerogels tsis muaj adarsion. Nws cov cuab yeej ua haujlwm yog manifested raws li lub zog tawv nqaij, thiab lub zog compressive tom qab kev sib txawv ntau dua lossis sib sib zog nqus tau txawv ntawm cov gels Steptoelastic. Cov khoom saum npoo av tuaj yeem hloov kho lub zog saum npoo los ntawm hydrophobic lossis hydrophilic hloov kho, tab sis lawv tseem tsis tau muaj adhes-adhesiveness.
Qee cov pa hluav taws xob yuav siv cov nplaum ua kom raws li cov txheej txheem sib txuas, uas yuav ua rau pej xeem tsis nkag siab uas aerogels muaj cov khoom nplaum nplaum. Qhov tseeb, Aerogels lawv tus kheej tsis nplaum, thiab lawv cov haujlwm yog kev cuam tshuam hauv kev sib cais ntawm thermal thiab cov qauv nruj. Ib qho ntxiv, hauv kev txhim kho thaum ntxov, lub xeev theem nrab ntawm cov khoom siv sol-gel yuav raug yuam kev, ntxiv exacerbating rau cov khoom tsis to taub ntawm cov aerogels.
3. Kev txheeb xyuas cov ntawv teev cov lus qhia kev ua yeeb yam
Raug cov ntaub ntawv tsis yog cov nplaum
Daim ntawv thov ntawm Airgel nyob rau hauv ntau thaj teb tau tshawb xyuas tag nrho nws cov txiaj ntsig raws li cov khoom tsis muaj txiaj ntsig. Hauv kev ua haujlwm ntawm lub tsev rwb thaiv tsev, Airgel feem ntau tau tso rau hauv phab ntsa kab noj hniav ua ke, uas tuaj yeem txhim kho lub thermal rwb thaiv tsev ua haujlwm ntawm lub tsev tsis muaj tsev. Vim nws cov ultra-qes qis thiab zoo heev thermal rwb thaiv tsev ua haujlwm, txo lub zog noj, thiab txhim kho lub zog txuag ntawm lub tsev. Nyob rau hauv daim ntawv thov ntawm cov kav dej muaj kev lag luam, airgel tseem qhia nws cov yam ntxwv tsis yog adhesive. Lub tshuab luam yeeb ua kom prefabricated yog ntsia los ntawm cov kws kho mob SNAP-ntawm txoj kev. Lub airgel yog siv ua cov khoom siv thermal rwb thaiv tsev ntawm cov yeeb nkab thiab yog ncaj qha rau hauv cov plhaub av tsis muaj kev siv cov nplaum. Txoj kev teeb tsa no tsis yog tsuas yog siv tau yooj yim thiab txuag tau, tab sis kuj tseem yuav zam cov kev laus thiab ua rau cov khoom ua haujlwm tsis zoo.
Daim ntawv thov puas muaj cov nplaum
Txawm hais tias airgel nws tus kheej tsis muaj cov khoom nplaum muaj nplaum, nws cov ntawv thov sib txuas nrog cov nplaum hauv cov khoom sib xyaw qhia tau cov txiaj ntsig tshwj xeeb. Piv txwv li, hauv multure-txheej rwb thaiv tsev ntawm cov huab cua, Airgel muaj kev lom zem thiab txhuas ntawv los ntawm Silicone Helding los tsim cov txheej muaj zog thermal. Cov qauv no yuav ua tau zoo tiv thaiv ntau dua thaum muaj zog thiab lub zog ntawm cov ntawv sau ua ke hauv cov chaw muaj ib puag ncig. Tsis tas li ntawd, Aerogels tseem muaj dav nyob rau hauv thaj teb ntawm kev ua tshuaj pleev xim ua haujlwm. Los ntawm dispersing airgel hmoov nyob rau hauv ib phau ntawv no, ib qho kev sib cais thermal rwb thaiv tsev tuaj yeem npaj tau. Cov txheej no tsis yog muaj qhov zoo thermal rwb thaiv tsev zog, tab sis kuj tseem tuaj yeem ua raws li ntau qhov chaw kom muab kev tiv thaiv ntev ntev.
4. Xaus thiab Cov Lus Taw Qhia Qauv
Txhawm rau txhawb nqa cov ntawv thov ua qauv ntawm cov khoom siv Airgel thiab txhim kho cov kev lag luam zoo tshaj plaws ntawm "cov khoom siv ntshiab" thiab "cov ntaub ntawv ntshiab plaw" hauv kev tis npe ntawm cov ntaub ntawv. "Ntshiab Airgel" yog hais txog cov ntaub ntawv tsuas yog muaj airgel substrates, thaum "Airgel Composite" yog cov composites tsim los ntawm kev sib xyaw ua ke ntawm Airgel thiab lwm yam ntaub ntawv. Qhov kev sib cav no tuaj yeem pab cov neeg ua haujlwm ntawm kev lag luam yog qhov tseem ceeb ntawm Aerogels thiab zam cov kev siv rau kev sib koom tes nrog kev sib raug zoo thiab kev ruaj ntseg ruaj khov. Ib qho ntxiv, cov nplaum ntsuas cov qauv rau AEROGELS yuav tsum tau txhim kho. Nws raug nquahu kom txhim kho ASTM muaj cov kev xav tau uas twb muaj lawm thiab sab nraud sib cuam tshuam, suav nrog kev sib koom tes sab nraud, suav nrog kev ua kom ruaj khov, thiab kev ua haujlwm nyob rau hauv ib puag ncig ib puag ncig. Kev txhim kho ntawm cov qauv xeem no tuaj yeem muab cov kev siv protustre ntawm aerogels thiab txhawb lawv cov ntawv thov thoob plaws teb thiab txhawb nqa lawv cov ntawv thov thoob plaws teb thiab txhawb nqa lawv cov ntawv thov thoob plaws teb thiab txhawb nqa lawv cov ntawv thov thoob plaws teb thiab txhawb nqa lawv cov ntawv thov thoob plaws teb thiab txhawb lawv txoj kev tsim kho tshiab, Aerospace, Electronics, thiab lwm yam.
Raws li cov khoom tsis sib xws yog cov khoom siv ntom ntom nti thiab nws tsis tseem ceeb muaj cov nplaum nplaum ntawm cov khoom lag luam tsoos. Yog li ntawd, nyob rau hauv lub ntawv thov tiag tiag ntawm Aerogels, yog qhov yuav tsum tau ua haujlwm sib haum, nws yog feem ntau tsim nyog siv exogenous adhesives kom ua tiav nws. Nkag siab txog cov xeeb ceem tseem ceeb no pab zam kev to taub tsis muaj kev nkag siab txog kev tshawb fawb airgel, tso cai rau kev siv airgel hauv kev lag luam tsim qauv thiab engineering cov ntawv thov. Nrog kev txhim kho cov cuab yeej ua lag luam, kev sib koom ua ke hauv kev tsim kho kom zoo thiab txhawb nqa kev tiv thaiv kev noj qab haus huv thiab kev tiv thaiv ib puag ncig, cov khoom siv hluav taws xob ib puag ncig, cov khoom siv hluav taws xob thiab lwm thaj teb.
