Zirconia nanopowder: ib qho khoom siv tshiab rau "qab" 5g xov tooj txawb

Tau qhov twg los: Science thiab thev naus laus zis txhua hnub: Cov ib txwm ua ntawm cov khib nyiab alkaline uas yog qhov nyuaj los kho cov pa phem, ua rau ib puag ncig ib puag ncig. High-zog pob milling yog lub zog txuag thiab cov khoom siv muaj peev xwm txhim kho cov kev cog lus ntawm 5g thev naus laus zis, ntse xov tooj yog nyob ntsiag to hloov lawv tus kheej "khoom siv". 5G Kev sib txuas lus siv lub spectrum saum toj 3 gigahertz (GHz), thiab nws millimeter villowength yog heev. Yog tias 5G lub xov tooj txawb siv cov hlua hluav taws xob hlau, nws yuav cuam tshuam rau lossis thaiv cov teeb liab. Yog li ntawd, cov khoom siv ceramic nrog cov yam ntxwv ntawm tsis muaj teeb meem shielding, siab tawv, muaj zog los ua ib qho kev xaiv tseem ceeb rau cov tuam txhab xov tooj ntawm tes nkag rau hauv 5g era. Bao Jinexiao, tus xibfwb ntawm sab hauv Mongolia University of Science rau Smart Inorganic cov khoom siv thim rov qab xav tau kev hloov kho sai. Wang Sikai, General Tus Tswj Xyuas ntawm Sab Hauv Tebchaws Mongolia Jingtao Kev Tshawb Fawb Txog Kev Lag Luam Hauv Ntiaj Teb, Lub Chaw Haujlwm Hauv Ntiaj Teb Kev siv thev naus laus zis ntau kuj tau nyiam ntau xim.as cov ntaub ntawv tshiab cov ntsiab lus tseem ceeb, cov ntaub ntawv ua haujlwm zoo nkauj thiab cov khoom siv polymonia ceramic thiab lwm cov khoom siv rau cov khoom sib xyaw. Raws li cov qauv kev ua si, zirconia cov khoom lag luam zoo li lub zog, kev kho mob hauv ntiaj teb, thiab lub zog kho mob tau ntau dua li xyoo, thiab cov khoom siv hluav taws xob tau txais kev tsim kho mobile "Cov kev ua yeeb yam ntawm cov kab ke zirconia ncaj qha yog tsim kev npaj cov hmoov loj, yog li kev txhim kho cov khoom tseem ceeb tshaj plaws hauv kev npaj cov khoom tseem ceeb, yog li kev txhim kho cov khoom tseem ceeb tshaj plaws Ntsuab lub zog loj pob pob milling txoj kev kawm yog heev nrhiav tau tom qab los ntawm cov kws tshaj lij. Kev tsim cov zirconia nano-hmoov feem ntau yog siv cov khoom siv tsis zoo thiab cov hmoov av uas tsis tshua muaj txiaj ntsig zoo los kho cov khoom siv Nws yuav ua rau muaj kuab paug loj thiab ua kom puas tsuaj rau lub ecological ib puag ncig. "Raws li kev sojntsuam, nws yuav siv li 50 tons dej los tsim ib qho ton ntawm cov dej khib nyiab, thiab kev kho kom zoo dua thiab kev kho kom zoo tshaj plaws." Wang Sikai tau hais. Nrog kev txhim kho ntawm kev tiv thaiv ib puag ncig txoj cai lij choj, cov khoom lag luam npaj nyuaj thiab tsis muaj txiaj ntsig los tsim kho cov thev naus laus zis ntawm zirconia nano-hmoov. "Tawm ntawm cov keeb kwm no, nws tau dhau los ua cov kev tshawb fawb qhib los npaj cov txheej txheem zirconia-cov khoom siv hluav taws xob ntau dua tom qab los ntawm cov voj voog science." Bao Jin tus tshiab. High-zog pob milling hais txog kev siv tshuab hluav taws xob kom ntxias cov tshuaj lom neeg thiab cov khoom siv ua kom zoo nkauj, yog li los npaj cov khoom tshiab. Raws li cov thev naus laus zis tshiab, nws tuaj yeem pom tseeb txog kev ua kom muaj zog, txhawb nqa cov khoom xa tawm ntawm cov hmoov av, txhim kho cov khoom sib xyaw, txhawb nqa cov khoom sib xyaw thiab kev txhim kho cov khoom siv hluav taws xob tsawg, txhawb nqa cov khoom sib xyaw thiab kev sib cais ntawm cov ntaub ntawv. Nws yog lub zog-txuag thiab cov khoom siv tau zoo tshaj plaws nrog kev muaj kev lag luam zoo tswv yim tsim cov tshuab tsim muaj xim ceramics. Hauv kev ua lag luam thoob ntiaj teb, cov khoom siv zirconia-hmoov hmoov tau nkag mus rau theem ntawm kev tsim kev txhim kho kev lag luam. Wang Sikai hais qhia cov neeg tshaj tawm: "Cov chaw tsim khoom zoo li no yog cov khoom siv hluav taws xob zoo nkauj heev. muaj nce xyoo dhau los, yog li nws yog qhov nrawm dua thiab tsim cov kev tshawb fawb me me thiab cov khoom siv hauv ntiaj teb no thiab ntau dua. Kev lag luam, zirconia nanopowder tau npaj los ntawm high zog pob milling tau zoo li qub, uas tsis muaj kuab paug, uas tsis muaj nqi thiab zoo bramility. "Bao Xin tau hais. Cov thev naus laus zis tsis tuaj yeem ua tau tsuas yog ua tau raws li cov hmoov 5G xov tooj, cov khoom siv hluav taws xob, ceramic pob ntau yam xws li ceracic freaters xws li cerium oxide composite noj. Raws li tus kheej-tsim cov xim xim, cov kws qhia txuj ci kev lag luam ceramic los ntawm cov qauv hluav taws xob tsis muaj kev cuam tshuam nrog cov khoom siv hluav taws xob tsis zoo "Lub qub particle me me ntawm cov xim tsis tshua muaj zog pom kev ua haujlwm ntawm cov khoom siv hluav taws xob zoo nkauj heev xws li muaj peev xwm ua tau zoo dua qub Hardness. "Wang Sikai tau hais.
