Puas yog airgel pam rwb thaiv tsev?
Airgel Pam rwb thaiv tsev yog cov khoom siv siab heev uas tau txais txiaj ntsig zoo nyob rau xyoo tsis ntev los no vim nws cov khoom muaj txiaj ntsig tshwj xeeb. Paub txog nws lub teeb yuag thiab siab thermal kuj, airgel pamets yog siv nyob rau hauv ntau yam kev lag luam, kev lag luam, thiab cov chaw nyob. Cov pam vov no yog tsim los kom muaj cov khoom siv hluav taws kub ua haujlwm nyob hauv thaj chaw uas cov khoom siv rwb thaiv tsev. Kab lus no yuav tshawb txog cov yeeb yam tshwj xeeb ntawm cov pa pam vov, nws hom, thiab kev siv, nrog rau cov ntaub ntawv sib piv nrog lwm cov ntaub ntawv rwb thaiv tsev.
Ib daim pam airgel yog qhov siab -}} {Airged Silica Airgel nyob rau hauv ib tug fiber ntau matrix, xws li fiberglass. Cov qauv no muab cov rauv thaiv kom zoo tshaj plaws vim yog cov cua sov ua rau nws muaj zog heev, thaum muaj hluav taws xob ruaj khov, hloov tau, thiab tuav tau yooj yim. Cov pam vov no yog siv rau hauv cov ntawv thov uas xav tau qhov chaw muaj tsawg thiab muaj kev ua tiav, suav nrog cov kav dej, aerospace, thiab vaj tse.
Cov lus qhia rau Airgel Pam Rwb Thaiv Tsev
Cov pam airgel yog tsim los ntawm cov khoom siv cua, cov khoom siv lub teeb uas feem ntau hu ua "haus luam yeeb" khov thiab ntsej muag pob tshab. Cov ntaub ntawv yog feem ntau tsim ntawm silica, tab sis lwm cov tebchaw xws li carbon, polymer, thiab hlau oxides kuj tseem tuaj yeem siv los txhim kho nws cov kev ua tau zoo. Airgel nws tus kheej tau tsim thawj zaug thaum xyoo 1930, tab sis nws tsuas yog nyob rau hauv cov kev siv rwb thaiv tsev xws li airgel pam.
Cov pam vov no yog qhov hloov tau, lub teeb yuag, thiab tuaj yeem tuaj yeem ua kom yooj yim rau hauv ntau yam duab, ua rau lawv xav tau ntau yam kev xav tau. Airgel Pam Rwb thaiv tsev muaj cov tsis muaj tsuas yog thermal kuj tab sis tseem tseem ceeb zoo nyob rau hauv cov nqe lus {} kev txuag, hluav taws kub ib puag ncig.
Cov yam ntxwv tseem ceeb ntawm cov rwb thaiv tsev Pam rwb thaiv tsev
Siab Thermal Kuj:Airgel yog ib qho zoo tshaj plaws thermal insulators paub rau tus txiv neej. Nrog lub thermal conductivity li 0.015 w / mk, pam vov pam vov muab cov tshuaj tiv thaiv tshav kub kub thaum tswj cov tuab. Qhov no ua rau lawv zoo tshaj plaws rau cov ntawv thov uas seem tsis tshua muaj lossis qhov chaw uas cov khoom siv tuab rwb thaiv tsev yuav tsis muaj peev xwm.
Kev nthuav dav thiab hloov tau:Cov pam airgel yog lub teeb yuag heev, feem ntau uas tsuas yog ib feem ntawm cov ntaub ntawv rwb thaiv tsev. Txawm hais tias lawv lub teeb pom kev zoo, lawv tseem muab cov khoom lag luam insulating zoo. Qhov yooj yooj yim ntawm airgel pam mas tso cai rau lawv tau siv nyob rau hauv ntau hom ntawv, txawm tias qhwv li luam yeeb, los yog koom rau hauv cov ntaub ntawv tsim tsev.
Hluav Taws Kub:Ib qho ntawm cov khoom seem ntawm cov pam vov yog lawv cov hluav taws kub -} tiv taus cov khoom. Lawv tuaj yeem tiv taus qhov kub heev, feem ntau txog 1200 degree, tsis tas yuav poob lawv cov peev txheej insulating. Qhov no ua rau lawv xaiv tau zoo rau kev lag luam uas muaj kev kub ntxhov yog qhov kev txhawj xeeb, xws li hauv Aerospace, roj thiab roj av.
Eco - Tus phooj ywg:Cov pam airgel tau txiav txim siab ntau ib puag ncig ib puag ncig piv rau cov ntaub ntawv rwb thaiv tsev ib txwm muaj. Lawv lub teeb yuag txo qhov xav tau rau cov khoom loj ntawm cov khoom, thiab ntau lub aerogels yog tsim kev siv cov txheej txheem ua kom ruaj ntseg. Tsis tas li ntawd, Airgel qhov tsis- pakic thiab tsis {{}}}}}} kev noj qab haus huv rau ob qho tib si ntawm ib puag ncig thiab kev noj qab haus huv.
Cov Ntawv Thov Uas Muaj Rwb Thaiv Tsev Airgel Rwb Thaiv Tsev
Cov pam airgel tau siv nyob rau hauv ntau hom kev lag luam thiab cov ntawv thov vim lawv cov khoom tshwj xeeb. Qee qhov kev siv feem ntau suav nrog:
Aerospace thiab aviation:Cov pam vov dav hlau tau siv dav dav hauv nkoj dav dav thiab aviation los muab cov cua sov rwb thaiv tsev rau cov twj paj nruag thiab cov khoom sib xyaw ua kom sov. Lawv lub peev xwm los tiv thaiv ntau thaum tswj qhov hnyav yog qhov tseem ceeb rau cov ntawv thov no.
Roj thiab roj Kev Lag Luam:Nyob rau hauv cov roj thiab roj sector, airgel pam vov yog siv los tswj kav dej, tso tsheb hlau luam, thiab cov hlab ntsha hauv chaw hnyav. Lawv cov thermal zoo heev kom ntseeg tau tias cov txheej txheem yog tswj xyuas ntawm qhov kev pom kub zoo, tiv thaiv kev kub ceev lossis tsis xav tau kub.
Kev tsim kho thiab architecture:Hauv tsev thiab kev tsim kho, cov pam airgel yog siv rau ob qho duab thermal thiab acoustic rwb thaiv tsev. Lawv tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas muaj qhov chaw tsawg, xws li hauv siab-}}}} Retrofitates cov qauv qub. Lawv cov ntaub ntawv slim tso cai rau kev muaj siab tshaj plaws uas tsis muaj chaw sib cuam tshuam.
Kev Lag Luam Automotive:Cov pam airgel tau siv nyob rau hauv kev lag luam hauv tsheb, tshwj xeeb hauv kev ua haujlwm siab rau lub tsheb uas txo qhov hnyav thaum muaj kev kub ntxhov. Lawv feem ntau tau thov rau kev kaw cov tshuab, cov cav cav, thiab lwm thaj chaw raug cov huab cua txias.
Muab cov pam vov plob nrog lwm cov ntaub ntawv rwb thaiv tsev
Thaum sib piv cov pam airgel rau lwm cov ntaub ntawv rwb thaiv tsev feem ntau siv, ntau qhov sib txawv tseem ceeb sawv tawm:
Fiberglass rwb thaiv tsev:Fiberglass yog ib qho siv rwb thaiv tsev cov ntaub ntawv uas ib txwm siv vim nws cov nyiaj pheej yig thiab yooj yim ntawm kev teeb tsa. Txawm li cas los xij, nws yog bulizier dua li lub airgel thiab tsis muaj cov theem tib yam ntawm thermal kuj. Cov pam vov yog qhov sib zog nqus thiab sib dua tshaj cov fiberglass, ua rau lawv zoo tagnrho rau kev siv thiab qhov hnyav yog nyob ntawm tus nqi.
Cov Nkawv Cov Tsiaj:Cov ntaub plaub pob zeb yog lwm cov ntaub ntawv rwb thaiv tsev siv ntau, tshwj xeeb tshaj yog hauv cov ntawv thov kev lag luam. Thaum nws yog hluav taws kub - tiv taus, nws yog qhov hnyav dua thiab tuab dua cov pam airgel. Ib qho ntxiv, cov ntaub plaub hauv av muaj qis dua thermal conductivity, lub ntsiab lus nws tsis yog ua kom muaj txiaj ntsig raws li cov huab cua ua rau muaj kev tiv thaiv kub.
Tsuag npuas pw rwb thaiv tsev:Tsuag npuas ua npuas ncauj yog nrov rau nws lub peev xwm los nthuav dav thiab sau qhov khoob thiab voids nyob rau ntau yam kev siv. Txawm li cas los xij, tshuaj tsuag ua npuas dej tuaj yeem ua tau zoo dua nyob rau hauv kub heev thiab yuav tsis muaj tib lub ntev- loadity li airgel. Cov pam vov plev, ntawm qhov tod tes, muaj ntau dua resilient mus rau qhov ntsuas kub tshaj thiab muab cov khoom lag luam zoo dua nyob rau lub sijhawm.
