Cov kws tshawb fawb los ntawm University of Bath hauv tebchaws United Kingdom tau tshawb pom tias kev tshem tawm airgel hauv cov qauv honeycomb ntawm lub tshuab dav hlau tuaj yeem ua tiav cov suab nrov txo.Cov qauv zoo li Merlinger ntawm cov khoom siv airgel no yog lub teeb heev, uas txhais tau hais tias cov khoom siv no tuaj yeem siv los ua ib qho insulator nyob rau hauv lub cav compartment ntawm lub dav hlau uas yuav luag tsis cuam tshuam rau tag nrho qhov hnyav.
Tam sim no, University of Bath hauv UK tau tsim cov khoom siv graphene lub teeb heev, graphene oxide-polyvinyl cawv aerogel, hnyav tsuas yog 2.1 kilograms ib cubic meter, uas yog cov khoom siv hluav taws xob zoo tshaj plaws puas tau tsim.
Cov kws tshawb fawb hauv tsev kawm ntawv ntseeg tias cov khoom siv no tuaj yeem txo cov suab nrov ntawm lub cav thiab txhim kho cov neeg caij tsheb.Nws tuaj yeem siv los ua cov khoom siv insulating hauv cov tshuab dav hlau kom txo cov suab nrov ntau li 16 decibels, yog li ua rau lub tshuab dav hlau emit 105 Lub decibel roar poob ze rau lub suab ntawm lub tshuab ziab khaub ncaws.Tam sim no, pab pawg tshawb fawb tab tom sim thiab ua kom zoo dua cov khoom siv no kom muab cov cua sov zoo dua, uas yog qhov zoo rau kev siv roj thiab kev nyab xeeb.
Cov kws tshawb fawb uas tau coj txoj kev tshawb fawb kuj tau hais tias lawv tau ua tiav cov khoom siv tsawg tsawg los ntawm kev siv cov kua ua ke ntawm graphene oxide thiab polymer.Cov khoom siv tawm tshiab no yog cov khoom siv ruaj khov, tab sis muaj huab cua ntau, yog li tsis muaj qhov hnyav lossis kev txwv kev ua haujlwm ntawm kev nplij siab thiab suab nrov.Thawj qhov tseem ceeb ntawm pab pawg tshawb fawb yog koom tes nrog cov koom tes hauv aerospace los sim cov txiaj ntsig ntawm cov khoom siv no ua cov khoom siv suab nrov rau cov tshuab dav hlau.Thaum pib, nws yuav raug siv rau hauv thaj chaw aerospace, tab sis nws kuj tseem siv tau rau ntau qhov chaw xws li tsheb thiab tsheb thauj mus los thiab kev tsim kho.Nws kuj tseem siv tau los ua cov vaj huam sib luag rau cov nyoob hoom qav taub lossis lub cav tsheb.Pab neeg tshawb fawb cia siab tias cov airgel no yuav nkag mus rau theem siv hauv 18 lub hlis.
