Qhia Txog Kev Tshawb Fawb Tom Qab Cerium Oxide: Yuav Ua Li Cas Nws Thiaj Ua Tau Qhov Zoo Tshaj Plaws Ntawm Qhov Chaw Atomic
Hauv kev lag luam niaj hnub no, kev ua tiav cov iav du thiab du yog qhov tseem ceeb rau kev ua kom muaj kev ua haujlwm zoo tshaj plaws. Hauv plawv ntawm cov txheej txheem no yog cerium oxide (CeO₂) polishing hmoov [1], ib qho khoom siv tseem ceeb rau kev ua kom iav zoo nkauj, muaj nqis rau nws cov khoom tshwj xeeb. Nws qhov tseem ceeb tsis yog nyob rau hauv nws qhov kev ua haujlwm zoo tshaj plaws xwb tab sis kuj nyob rau hauv nws lub peev xwm los ua tiav qhov tseeb ntawm qhov chaw nanoscale, ua raws li cov kev cai nruj los ntawm cov iav tiaj tus mus rau cov iav tsom iav aerospace.
Cov Ntsiab Cai Txog Kev Tshawb Fawb: Yuav Ua Li Cas Cerium Oxide Pab Kom Tshem Tawm Cov Khoom Siv Atomic-Level
Qhov zoo tshaj plaws ntawm cerium oxide polishing hmoov yog vim nws cov yam ntxwv tshwj xeeb ntawm lub cev thiab tshuaj lom neeg. Lub cev, cov hmoov cerium oxide zoo muaj qhov sib npaug ntawm qhov loj me ntawm cov khoom me me hauv qab micron (feem ntau nrog D50 hauv qhov ntau ntawm 0.3-1.5μm) thiab qhov nyuaj siab (kwv yees li 7 ntawm Mohs scale). Cov yam ntxwv ntawm cov qauv no tso cai rau nws tsim ntau txhiab lab qhov me me thaum lub sijhawm polishing, ua rau yooj yim txawm tias qhov puas ntawm qhov chaw iav.
Qhov tseem ceeb tshaj plaws, nws txoj kev txhuam tshuaj lom neeg suav nrog kev tsim cov txheej txheem hloov pauv los ntawm Ce-O-Si kev sib txuas tshuaj lom neeg ntawm cerium oxide thiab qhov chaw ntawm silicate iav hauv qab kev siab thiab kev sib txhuam. Cov txheej txheem hloov pauv no tau tsim thiab tshem tawm tas li los ntawm kev txiav tshuab, ua tiav kev tshem tawm cov khoom siv atomic. Qhov kev ua haujlwm sib xyaw ua ke ntawm cov khoom siv thiab tshuaj lom neeg no ua rau muaj kev tshem tawm cov khoom siv ntau dua thiab txo qhov puas tsuaj ntawm qhov chaw piv rau kev txhuam tshuab huv.
Kev Ua Haujlwm Txog Kev Siv Tshuab: Kev Ntsuas Qhov Zoo ntawm Cerium Oxide Polishing Powder
Cov ntsuas kev ntsuas tseem ceeb rau kev ntsuam xyuas cov hmoov txhuam cerium oxide tsim ib qho kev ua haujlwm zoo:
Cov Khoom Siv Oxide Tsis Tshua Muaj (REO) thiab Cerium Oxide Purity: Cov hmoov txhuam hniav zoo yuav tsum muaj REO ≥ 90%, kom ntseeg tau tias muaj kev sib xws thiab ruaj khov ntawm cov tshuaj txhuam hniav.
Kev Faib Qhov Loj ntawm Cov Khoom Me Me: D50 (qhov loj ntawm cov khoom me me nruab nrab) thiab D90 (qhov loj ntawm cov khoom me me uas pom muaj 90% ntawm cov khoom me me) ua ke txiav txim siab qhov kev ua kom raug polishing; rau kev ua kom pom tseeb optical polishing, D50 ≤ 0.5μm thiab D90 ≤ 2.5μm yog qhov yuav tsum tau ua, qhia txog kev faib me me.
Kev Ruaj Ntseg ntawm Kev Ncua: Cov khoom zoo yuav tsum tswj kev ncua ruaj khov rau 60-80 feeb hauv cov tshuaj txhuam kom tsis txhob txhuam tsis sib npaug vim muaj kev sib xyaw.
Cov ntsuas no ua ke tsim cov qauv ntsuam xyuas kev ua tau zoo rau cov hmoov txhuam ceria, uas cuam tshuam ncaj qha rau cov txiaj ntsig kawg ntawm kev txhuam.
Daim Ntawv Thov: Txij Li Txhua Hnub Iav Mus Rau Kev Siv Tshuab Tshiab
Kev siv tshuab polishing cerium oxide tau nkag mus rau ntau qhov chaw lag luam niaj hnub no:
Kev Lag Luam Zaub thiab Optoelectronic: Nws yog ib qho tseem ceeb rau kev siv rau kev txhuam ITO conductive iav, ultra-thin npog iav, thiab cov kua siv lead ua zaub vaj huam sib luag, ua tiav sub-nanometer roughness yam tsis ua rau puas ITO zaj duab xis.
Cov Cuab Yeej Siv Tau: Siv rau hauv kev ua cov khoom sib txawv xws li cov iav, cov prisms, thiab cov lim dej kho qhov muag, cerium Oxide yog qhov tshwj xeeb tshaj yog rau kev ua kom raug ntawm cov iav kho qhov muag tshwj xeeb, xws li iav flint, txo lub sijhawm polishing los ntawm 40% -60%.
Kev Tsim Khoom Siv Siab Tshaj Plaws: Hauv kev tsim cov khoom siv kho qhov muag ultra-precision xws li semiconductor silicon wafers, spacecraft observation windows, thiab laser gyroscope mirrors, high-purity nano cerium oxide (purity ≥ 99.99%, particle size ≤ 0.3μm) tuaj yeem ua tiav qhov tiaj tiaj ntawm qhov chaw atomic.
Kev Kho Kom Zoo Nkauj thiab Kev Ua Yeeb Yam: Siv rau hauv kev kho kom zoo nkauj ntawm cov khoom kim heev xws li cov pob zeb cuav, cov khoom siv tes ua siv lead ua, thiab cov ntsej muag saib siab heev, nws xa cov teebmeem pom tseeb thiab tsis muaj khawb.
Txij li qhov ci ntsa iab ntawm cov ntxaij vab tshaus smartphone mus rau qhov tseeb ntawm cov iav tsom iav hauv qhov chaw, cerium oxide polishing hmoov tau ua tiav kev nce qib tseem ceeb hauv kev pom ntawm tib neeg los ntawm nws txoj haujlwm hauv lub ntiaj teb me me. Cov thev naus laus zis no, uas muab kev tshawb fawb txog cov ntaub ntawv, kev sib txuas lus, thiab kev ua haujlwm raug, txuas ntxiv thawb cov kev txwv ntawm kev kho qhov chaw iav. Txhua qhov kev sib cuam tshuam me me thaum lub sijhawm polishing qhia txog yuav ua li cas cov khoom ntuj ntawm cov khoom siv tuaj yeem hloov pauv mus rau hauv lub zog uas hloov peb qhov kev pom.
