Taw qhia rau Airgel
Aerogels yog ultralight ntxeem tau cov ntaub ntawv uas tau piav raws li “cov pa taws khov” los yog huab cua khov vim lawv cov tsos ethereal. Lawv tau tsim thawj zaug hauv 1931 los ntawm American chemist Samuel S. Kistler, leej twg tab tom sim hloov cov kua hauv gels nrog roj yam tsis muaj kev sib tsoo cov gel cov qauv. Aerogels yog tsim los ntawm ib lub network ntawm cov khoom sib txuas sib txuas hauv ib qho porous peb-dimensional matrix., uas yog puv nrog cua, muab lawv cov tsis tshua muaj ntom thiab siab porosity.
Cov yam ntxwv ntawm Airgel
Tsawg ceev: Aerogels tuaj yeem tsawg dua 3 mg/cm³, ua rau lawv ib yam ntawm cov khoom siv lightest paub.
Siab Porosity: Lawv feem ntau muaj ntau dua 95% porosity, nrog rau thaj tsam sab hauv loj heev.
Thermal rwb thaiv tsev: Vim lawv cov porosity siab thiab tsawg thermal conductivity, aerogels yog cov insulators zoo heev.
Suab Absorption: Lawv cov qauv ntxeem tau tso cai rau cov khoom zoo acoustic rwb thaiv tsev.
Optical Transparency: Qee cov aerogels, tshwj xeeb tshaj yog silica aerogels, tuaj yeem ua optically pob tshab, zoo ib yam li iav.
Mechanical Strength: Txawm yog lub teeb yuag, Qee cov aerogels tuaj yeem pom muaj zog txhua yam uas cuam tshuam rau lawv qhov hnyav.
Hydrophobicity: Qee cov aerogels tuaj yeem kho tau los ua dej-tiv taus, ua rau lawv haum rau ntau yam ib puag ncig.
Kev siv ntawm Airgel
Lub tsev rwb thaiv tsev: Airgel pam vov thiab panels yog siv rau lub zog txuag hluav taws xob lub tsev rwb thaiv tsev.
Aerospace Kev Lag Luam: Siv nyob rau hauv spacecraft rau lawv cov rwb thaiv tsev thiab lub teeb yuag zog, suav nrog cov ntaub thaiv cua sov thiab cov tsheb rov nkag.
Roj ntxuav: Hydrophobic aerogels tuaj yeem nqus cov roj tab sis tshem tawm cov dej, pab tau hauv kev ntxuav cov roj nchuav.
Catalysts: Hauv cov txheej txheem tshuaj, aerogels pab raws li kev txhawb nqa catalyst zoo vim lawv qhov chaw loj.
Khaub ncaws thiab khau: Siv rau hauv cov khaub ncaws ua haujlwm siab thiab khau rau kev rwb thaiv tsev thiab kev nplij siab.
Kev siv tub rog: Rau cov iav tiv thaiv thiab kev tiv thaiv ballistic vim lawv muaj peev xwm nqus tau.
Electronics: Raws li thermal barriers nyob rau hauv high-density hluav taws xob khoom siv los tiv thaiv overheating.

FAQs txog Airgel
Dab tsi yog lub ntiaj teb cov ntaub ntawv rau lub lightest airgel?
Lub lightest airgel ntawm cov ntaub ntawv yog aerographite, uas muaj ib tug ceev ntawm xwb 0.18 mg/cm³.
Yog airgel flammable?
Ntshiab silica airgel tsis yog flammable, tab sis aerogels ua los ntawm lwm cov ntaub ntawv tuaj yeem combustible nyob ntawm lawv cov muaj pes tsawg leeg.
Airgel tuaj yeem siv tau?
Recycling aerogels tuaj yeem nyuaj vim lawv cov khoom tshwj xeeb, tab sis kev tshawb fawb tseem tab tom tsim txoj hauv kev los rov ua dua cov ntaub ntawv no.
Airgel nqi npaum li cas?
Aerogels tuaj yeem kim, nrog cov nqi sib txawv nyob ntawm seb hom thiab ntau npaum li cas. Cov nqi tuaj yeem nyob ntawm kaum mus rau pua pua daus las ib cubic meter.
Dab tsi yog kev noj qab haus huv cuam tshuam nrog airgel?
Thaum aerogels feem ntau suav hais tias muaj kev nyab xeeb, Kev nqus plua plav thaum tuav tuaj yeem tsim teeb meem. Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum ua haujlwm nrog aerogels.
