Hauv lub ntiaj teb niaj hnub no, kev tsim cov ntaub ntawv tshiab ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam. Ib qho kev tsim kho tshiab zoo li no yog cov iav hollow microspheres, kuj hu ua cov npuas iavCov khoom me me no, nrog lawv cov yam ntxwv tshwj xeeb thiab kev siv, tau txais kev saib xyuas zoo thiab kwv yees tias yuav muaj yav tom ntej zoo hauv ntau qhov chaw.
Cov iav me me uas muaj qhov khoob yog cov khoom siv uas tsis hnyav, siv tau ntau yam, thiab muaj cov yam ntxwv zoo heev rau kev rwb thaiv tsev vim lawv cov qauv khoob. Cov iav me me no, feem ntau yog li ntawm 1 txog 100 micrometers hauv qhov loj me, yog ua los ntawm kev txhaj roj lossis pa rau hauv cov iav uas kub. Yog li ntawd, cov iav khov kho nrog lub hauv paus khoob, tsim cov iav me me no nrog cov yam ntxwv zoo heev.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov iav hollow microspheres yog lawv qhov ceev qis heev. Nrog rau qhov ceev qis li 0.2 grams ib cubic centimeter, cov microspheres no tuaj yeem txo qhov hnyav ntawm cov ntaub ntawv yam tsis muaj kev cuam tshuam rau lub zog lossis kev ncaj ncees. Cov yam ntxwv no ua rau lawv zoo tagnrho rau kev tsim cov ntaub ntawv sib dua hauv kev lag luam xws li aerospace, automotive, thiab kev tsim kho.
Hauv kev lag luam aerospace, qhov twg qhov hnyav txo qis yog qhov tseem ceeb, cov iav microspheres hollow pom lawv daim ntawv thov hauv ntau yam khoom. Los ntawm kev koom ua ke cov microspheres no rau hauv cov ntaub ntawv aerospace, cov chaw tsim khoom tuaj yeem ua tiav qhov hnyav txo qis yam tsis muaj kev cuam tshuam rau qhov zoo thiab kev ua tau zoo. Qhov no ua rau kev siv roj zoo dua, muaj peev xwm thauj khoom ntau dua, thiab kev txuag nqi tag nrho.
Kev lag luam tsheb yog lwm qhov kev lag luam uas tau txais txiaj ntsig los ntawm kev koom ua ke ntawm cov iav microspheres hollow. Los ntawm kev koom ua ke cov microspheres no rau hauv cov khoom siv tsheb xws li lub cev vaj huam sib luag, cov khoom sab hauv, thiab txawm tias cov log tsheb, cov chaw tsim khoom tuaj yeem ua tiav qhov hnyav txo qis thiab tom qab ntawd txhim kho kev siv roj. Tsis tas li ntawd, cov microspheres no tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov ntaub ntawv, ua rau lawv ruaj khov thiab tiv taus kev hnav thiab rhuav.
Kev tsim kho yog lwm qhov chaw uas cov iav me me uas tsis muaj qhov rais qhia tau tias muaj peev xwm loj heev. Los ntawm kev ntxiv cov iav me me no rau hauv cov ntaub ntawv cementitious, xws li cov pob zeb ua vaj tse, cov chaw tsim khoom tuaj yeem tau txais cov ntaub ntawv tsim kho uas tsis hnyav nrog cov khoom rwb thaiv tsev zoo heev. Qhov no pab txhawb rau kev siv hluav taws xob zoo, txo cov pa roj carbon dioxide, thiab kev ruaj khov ntawm cov tsev.
Cov kev cia siab ntawm kev loj hlob ntawm cov iav hollow microspheres tsis yog tsuas yog siv rau cov lag luam no xwb. Muaj kev txaus siab rau kev siv lawv hauv cov chaw xws li kev khawb roj thiab roj av, kev kho mob, thiab txawm tias cov xim thiab cov txheej txheem. Hauv kev lag luam khawb roj thiab roj av, cov microspheres no tuaj yeem siv los txo qhov ceev ntawm cov kua dej drilling, txhim kho kev ua haujlwm zoo thiab kev ua haujlwm ntawm cov txheej txheem drilling. Hauv kev kho mob, cov iav hollow microspheres raug tshawb nrhiav ua cov kab ke xa tshuaj thiab rau cov ntaub so ntswg engineering daim ntawv thov, vim lawv cov biocompatibility thiab cov khoom tso tawm tswj. Tsis tas li ntawd, hauv ntiaj teb ntawm cov xim thiab cov txheej txheem, cov microspheres no txhim kho cov khoom xws li thermal rwb thaiv tsev, kev cuam tshuam tsis kam, thiab kev txhim kho cov qauv.
Raws li qhov kev thov rau cov khoom siv uas tsis hnyav, tsis ua rau ib puag ncig puas tsuaj, thiab siv hluav taws xob tsawg zuj zus, cov iav microspheres uas tsis muaj qhov khoob yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau no. Lawv cov yam ntxwv tshwj xeeb, suav nrog qhov ceev tsawg, cov khoom rwb thaiv tsev, thiab kev hloov pauv tau yooj yim, ua rau lawv yog qhov kev cia siab rau cov neeg tsim kho tshiab thiab cov chaw tsim khoom hauv ntau qhov chaw. Nrog kev tshawb fawb thiab kev txhim kho tas mus li, peb tuaj yeem cia siab tias yuav pom kev nce qib ntxiv thiab kev siv cov iav microspheres uas yuav hloov pauv kev lag luam thiab pab txhawb rau yav tom ntej uas ruaj khov dua.
Hauv kev xaus lus, kev cia siab ntawm kev loj hlob ntawm cov iav hollow microspheres muaj kev cia siab zoo kawg li. Cov khoom me me no muaj cov yam ntxwv tshwj xeeb uas ua rau lawv zoo tagnrho rau kev siv hauv aerospace, automotive, kev tsim kho, thiab lwm yam. Nrog lawv lub peev xwm los txo qhov hnyav yam tsis muaj kev cuam tshuam lub zog, txhim kho cov khoom rwb thaiv tsev, thiab muab kev siv hluav taws xob zoo, cov iav microspheres hollow tau npaj los hloov pauv ntau yam kev lag luam. Thaum kev tshawb fawb thiab kev txhim kho txuas ntxiv mus, peb tuaj yeem cia siab tias yuav muaj kev nce qib zoo siab thiab kev tshawb nrhiav ntxiv txog lawv lub peev xwm, thaum kawg pab txhawb rau yav tom ntej ntsuab thiab ruaj khov dua.
