Zirconia Nanopowder: Ib yam khoom tshiab rau "tom qab" 5G xov tooj ntawm tes

Tau qhov twg los: Kev Tshawb Fawb thiab Tshuab Txhua Hnub: Cov txheej txheem kev tsim cov zirconia hmoov yuav tsim cov khoom pov tseg ntau, tshwj xeeb tshaj yog cov dej tsis tshua muaj siab alkaline uas nyuaj rau kev kho, ua rau muaj kuab paug loj heev. High-zog pob milling yog lub zog-txuag thiab txuag cov khoom siv thev naus laus zis, uas tuaj yeem txhim kho lub compactness thiab dispersibility ntawm zirconia ceramics thiab muaj ib tug zoo kev lag luam daim ntawv thov prospect.With lub advent ntawm 5G technology, ntse xov tooj yog ntsiag to hloov lawv tus kheej "khoom siv. ”. 5G kev sib txuas lus siv lub spectrum saum toj no 3 gigahertz (Ghz), thiab nws millimeter wavelength yog luv heev. Yog tias 5G lub xov tooj ntawm tes siv lub dav hlau hlau rov qab, nws yuav cuam tshuam nrog lossis tiv thaiv lub teeb liab. Yog li ntawd, cov ntaub ntawv ceramic nrog cov yam ntxwv ntawm tsis muaj teeb liab thaiv, siab hardness, kev nkag siab zoo thiab kev ua haujlwm zoo thermal nyob ze rau cov ntaub ntawv hlau tau maj mam dhau los ua qhov kev xaiv tseem ceeb rau cov tuam txhab xov tooj ntawm tes kom nkag mus rau 5G era. Bao Jinxiao, tus xibfwb ntawm Inner Mongolia University of Science thiab Technology, tau hais rau cov neeg sau xov xwm tias yog cov khoom siv tseem ceeb hauv cov khoom siv tsis yog hlau, cov ntaub ntawv ceramic tshiab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov khoom siv hauv xov tooj ntawm tes. ceev ceev. Wang Sikai, tus thawj coj ntawm Inner Mongolia Jingtao Zirconium Industry Co., Ltd. (tom qab no hu ua Jingtao Zirconium Kev Lag Luam), tau hais rau tus neeg sau xov xwm tias raws li cov ntaub ntawv tshaj tawm los ntawm Counterpoint, lub koom haum tshawb fawb thoob ntiaj teb, lub ntiaj teb kev xa khoom ntawm smartphone yuav. ncav cuag 1.331 billion units hauv 2020. Nrog rau kev thov ntau ntxiv rau zirconia ceramics siv hauv xov tooj ntawm tes backboards, nws R & D thiab kev npaj thev naus laus zis kuj tau txais kev nyiam ntau. hnyav ua haujlwm ib puag ncig uas cov ntaub ntawv hlau, cov ntaub ntawv polymer thiab feem ntau lwm cov ntaub ntawv ceramic tsis muaj peev xwm. Raws li cov txheej txheem, cov khoom siv zirconia ceramic tau siv rau hauv ntau qhov kev lag luam xws li lub zog, aerospace, machinery, tsheb, kev kho mob, thiab lwm yam, thiab lub ntiaj teb txhua xyoo noj yog tshaj 80,000 tons.With lub advent ntawm 5G era, ceramic li muaj qhia tau zoo dua thev naus laus zis hauv kev ua lub xov tooj ntawm tes backboards, thiab zirconia ceramics muaj qhov kev loj hlob dav dua. "Qhov kev ua tau zoo ntawm zirconia ceramics ncaj qha nyob ntawm qhov kev ua tau zoo ntawm cov hmoov, yog li txhim kho cov txheej txheem kev tswj hwm ntawm cov hmoov ua haujlwm siab, Nws tau dhau los ua qhov txuas tseem ceeb tshaj plaws hauv kev npaj zirconia ceramics thiab kev txhim kho cov khoom siv zirconia ceramics. "Wang Sikai hais ncaj ncees. Green high-zog pob milling txoj kev yog heev nrhiav tom qab los ntawm cov kws txawj. Kev tsim khoom hauv tsev ntawm zirconia nano-hmoov feem ntau siv cov txheej txheem tshuaj ntub dej, thiab tsis tshua muaj lub ntiaj teb oxide yog siv los ua stabilizer los tsim zirconia nano-hmoov.Cov txheej txheem no muaj cov yam ntxwv ntawm cov peev txheej loj thiab zoo sib xws ntawm cov khoom siv tshuaj lom neeg, tab sis qhov tsis zoo yog hais tias ib tug loj npaum li cas ntawm cov pov tseg yuav raug tsim nyob rau hauv cov txheej txheem ntau lawm, tshwj xeeb tshaj yog ib tug loj npaum li cas ntawm low-concentration alkaline khib nyiab uas yog ib qho nyuaj rau kho, thiab yog hais tias tsis kho kom raug, nws yuav ua rau muaj kuab paug loj thiab puas rau lub ecological ib puag ncig. "Raws li kev tshawb fawb, nws yuav siv li ntawm 50 tons ntawm dej los tsim ib tuj ntawm yttria-stabilized zirconia ceramic hmoov, uas yuav tsim tau ib tug loj npaum li cas ntawm cov dej khib nyiab, thiab cov rov qab thiab kho cov dej khib nyiab yuav ua rau kom tus nqi ntau lawm. "Wang Sikai hais. Nrog rau kev txhim kho ntawm Tuam Tshoj txoj cai tiv thaiv ib puag ncig, cov tuam txhab npaj zirconia nano-hmoov los ntawm cov txheej txheem ntub dej tau ntsib cov teeb meem uas tsis tau muaj dua.Yog li ntawd, yuav tsum tau tsim kom muaj kev npaj ntsuab thiab cov nqi qis ntawm zirconia nano-hmoov. "Raws li cov keeb kwm yav dhau los no, Nws tau dhau los ua qhov kev tshawb fawb hotspot los npaj zirconia nano-hmoov los ntawm kev huv thiab qis zog siv cov txheej txheem ntau lawm, ntawm cov uas lub zog siab pob milling txoj kev yog qhov feem ntau nrhiav tom qab los ntawm kev tshawb fawb thiab thev naus laus zis. "Bao Jin's novel. High-lub zog pob milling yog hais txog kev siv lub zog ntawm lub zog los txhawb cov tshuaj lom neeg los yog ua kom muaj kev hloov pauv ntawm cov qauv thiab cov khoom ntawm cov khoom, thiaj li npaj cov ntaub ntawv tshiab. Raws li cov cuab yeej tshiab, Nws tuaj yeem txo qis cov tshuaj tiv thaiv kev ua kom lub zog, ua kom zoo dua cov nplej loj, ua kom zoo dua qhov kev faib tawm ntawm cov hmoov hmoov, txhim khu kev sib txuas ntawm cov substrates, txhawb cov diffusion ntawm cov khoom ions thiab induce low-temperature chemical reactions, yog li txhim kho cov compactness thiab dispersibility ntawm cov ntaub ntawv. Nws yog ib qho kev txuag hluav taws xob thiab kev siv cov khoom siv tau zoo nrog cov ntawv thov kev lag luam zoo.Unique colouring mechanism tsim cov yeeb yuj ceramics. Hauv kev lag luam thoob ntiaj teb, zirconia nano-hmoov cov ntaub ntawv tau nkag mus rau theem ntawm kev tsim kho kev lag luam. Wang Sikai hais rau cov neeg sau xov xwm: "Nyob rau hauv cov teb chaws tsim thiab cheeb tsam xws li Tebchaws Meskas, Western Europe thiab Nyij Pooj, cov nplais ntawm zirconia nano-hmoov yog loj thiab cov khoom specifications kuj ua tiav. Tshwj xeeb tshaj yog Asmeskas thiab Nyij Pooj cov tuam txhab ntau lub teb chaws, Nws muaj kev sib tw zoo hauv patent ntawm zirconia ceramics. Raws li Wang Sikai, tam sim no, Tuam Tshoj tus tshiab ceramic manufacturing kev lag luam yog nyob rau hauv ib theem ntawm kev loj hlob sai, thiab qhov kev thov rau ceramic hmoov yog nce xyoo los ntawm lub xyoo, yog li nws yog ntau thiab ntau ceev los tsim cov txheej txheem zus tau tej cov nanometer zirconia tshiab. Hauv ob xyoos dhau los, Qee lub koom haum tshawb fawb hauv tsev thiab cov lag luam kuj tau pib tshawb fawb ntawm nws tus kheej thiab tsim zirconia nano-hmoov, tab sis feem ntau ntawm kev tshawb fawb thiab kev loj hlob tseem nyob rau theem ntawm kev sim me me hauv kev sim, nrog cov zis me me. thiab ib qho ntau yam. Nyob rau hauv qhov project ntawm "Xim Rare Earth Zirconia Nanopowder" siv los ntawm Ceramic Zirconia Kev Lag Luam, zirconia nanopowder tau npaj los ntawm lub zog siab pob milling solid-state cov tshuaj tiv thaiv txoj kev. -agglomerated grain hmoov nrog qhov loj ntawm 100 nanometers tuaj yeem tau txais, uas tsis muaj kuab paug, tsis tshua muaj nqi thiab zoo batch stability. " Bao Xin hais. Kev npaj thev naus laus zis tuaj yeem ua tsis tau tsuas yog ua tau raws li cov kev xav tau ntawm 5G xov tooj ntawm tes ceramic backboard, thermal barrier txheej cov ntaub ntawv rau aviation turbine xyaw, ceramic pob, ceramic riam thiab lwm yam khoom, tab sis kuj tuaj yeem nrov thiab siv rau hauv kev npaj ntau cov hmoov ceramics xws li raws li cerium oxide composite hmoov npaj. Raws li tus kheej-tsim xim txheej txheem, pab pawg neeg ntawm Ceramic Zirconium Kev Lag Luam tau txais cov txheej txheem sib xyaw ua ke thiab cov txheej txheem sib xyaw rau cov xim tsis qhia cov hlau ions ntxiv los ntawm cov txheej txheem optimization.Lub zirconia ceramics npaj los ntawm txoj kev no tsis tsuas yog muaj xim saturation thiab zoo. wettability, tab sis kuj tsis cuam tshuam rau cov khoom qub ntawm zirconia ceramics. "Qhov loj me me ntawm cov xim tsis tshua muaj ntiaj teb zirconia hmoov ua raws li cov thev naus laus zis tshiab yog nanometer, uas muaj cov yam ntxwv ntawm cov khoom me me, kev ua haujlwm siab sintering, qis sintering kub thiab lwm yam. Piv nrog rau cov txheej txheem tsim khoom ib txwm muaj, kev siv hluav taws xob dav dav yog txo qis.Production efficiency thiab ceramic processing yield tau zoo heev. Cov khoom siv ceramic siab heev npaj los ntawm txoj kev no muaj cov khoom zoo xws li lub zog siab, siab toughness thiab siab hardness. "Wang Sikai hais.
