Cov kws tshawb fawb los ntawm University of Bath hauv tebchaws United Kingdom tau pom tias kev dai airgel rau hauv cov qauv honeycomb ntawm lub cav dav hlau tuaj yeem ua tiav qhov txo qis suab nrov. Cov qauv zoo li Merlinger ntawm cov khoom siv airgel no yog lub teeb heev, uas txhais tau tias cov khoom siv no tuaj yeem siv ua cov khoom rwb thaiv tsev hauv lub cav ntawm lub dav hlau uas yuav luag tsis muaj kev cuam tshuam rau tag nrho qhov hnyav.
Tam sim no, University of Bath hauv UK tau tsim cov khoom siv graphene uas sib dua heev, graphene oxide-polyvinyl alcohol aerogel, hnyav tsuas yog 2.1 kilograms ib lub cubic meter, uas yog cov khoom siv rwb thaiv suab nrov tshaj plaws uas tau tsim.
Cov kws tshawb fawb ntawm lub tsev kawm ntawv ntseeg tias cov khoom siv no tuaj yeem txo qhov suab nrov ntawm lub cav dav hlau thiab txhim kho kev nplij siab ntawm cov neeg caij tsheb. Nws tuaj yeem siv ua cov khoom siv rwb thaiv tsev hauv cov cav dav hlau kom txo qhov suab nrov txog li 16 decibels, yog li ua rau cov cav dav hlau tso tawm 105. Lub suab nrov ntawm lub decibel poob ze rau lub suab ntawm lub tshuab ziab plaub hau. Tam sim no, pab pawg tshawb fawb tab tom sim thiab txhim kho 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 no kuj tau hais tias lawv tau ua tiav tsim cov khoom siv uas tsis muaj zog heev los ntawm kev siv cov kua ua ke ntawm graphene oxide thiab polymer. Cov khoom siv tshiab no yog cov khoom siv khov kho, tab sis muaj ntau huab cua, yog li tsis muaj qhov hnyav lossis kev txwv kev ua haujlwm zoo hauv kev nplij siab thiab suab nrov. Lub hom phiaj thawj zaug ntawm pab pawg tshawb fawb yog koom tes nrog cov neeg koom tes hauv aerospace los sim cov nyhuv ntawm cov khoom siv no ua cov khoom siv rwb thaiv suab rau cov cav dav hlau. Thaum pib, nws yuav raug siv rau hauv thaj chaw aerospace, tab sis nws kuj tseem siv tau rau ntau lwm qhov chaw xws li tsheb thiab kev thauj mus los hauv hiav txwv thiab kev tsim kho. Nws kuj tseem siv tau los ua cov vaj huam sib luag rau cov dav hlau helicopters lossis cov cav tsheb. Pab pawg tshawb fawb xav tias cov airgel no yuav nkag mus rau theem siv hauv 18 lub hlis.
