Chiyambi ndi Kugwiritsa Ntchito Cerium Oxide
I. Chidule cha Zamalonda
Cerium oxide (CeO₂), yomwe imadziwikanso kuti cerium dioxide,ndi oxide wa cerium, wokhala ndi mawonekedwe achikasu mpaka oyera. Monga woyimira wofunikira wa mankhwala a rare earth, cerium oxide imagwiritsidwa ntchito kwambiri popukuta magalasi, kuyeretsa utsi wa magalimoto, ziwiya zamagetsi, mphamvu zatsopano ndi zina chifukwa cha mawonekedwe ake apadera a mankhwala ndi mphamvu zake zoyambitsa. Malo ake osungunuka ndi pafupifupi 2400℃, ali ndi kukhazikika kwabwino kwa mankhwala, sasungunuka m'madzi, ndipo amatha kukhalabe olimba pansi pa kutentha kwakukulu komanso malo amphamvu ophikira.
Mu mafakitale opanga,cerium oxideNthawi zambiri imachotsedwa ku mchere wokhala ndi cerium (monga fluorocarbon cerium ore ndi monazite) ndipo imapezeka kudzera mu leaching ya acid, kuchotsa, kupopera, calcination ndi njira zina. Malinga ndi kuyera ndi kukula kwa tinthu, imatha kugawidwa m'magulu opukutira, magulu ofunikira, magulu amagetsi ndi zinthu za nano-grade, zomwe nano cerium oxide yoyera kwambiri ndiye chinthu chofunikira kwambiri pakugwiritsa ntchito zinthu zapamwamba.
II. Zinthu Zogulitsa
Kuchita bwino kwambiri popukuta:Cerium oxideIli ndi luso lopukuta lamakina, lomwe lingachotse msanga zolakwika pamwamba pa galasi ndikukongoletsa mawonekedwe ake.
Mphamvu yamphamvu ya redox: Kusintha kosinthika pakati pa Ce⁴⁺ ndi Ce³⁺ kumapatsa ntchito yapadera yosungira ndi kutulutsa okosijeni, makamaka yoyenera kuchitapo kanthu.
Kukhazikika kwamphamvu kwa mankhwala: Sikophweka kuchitapo kanthu ndi ma acid ndi ma base ambiri, ndipo kumatha kugwira ntchito bwino ngakhale zinthu zitavuta.
Kukana kutentha kwambiri: Kusungunuka kwambiri komanso kukhazikika kwa kutentha kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa kutentha kwambiri komanso zinthu zamagetsi.
Kukula kwa tinthu tomwe timatha kusinthidwa: Kukula kwa tinthu ta chinthucho kumatha kusinthidwa kuchokera ku micron kupita ku nanometer kuti tikwaniritse zosowa zosiyanasiyana zamafakitale.
III. Malo ofunikira kwambiri
1. Galasi ndi kupukuta kwa kuwala
Ufa wopukuta wa Cerium oxide ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito pokonza magalasi amakono. Mphamvu yake yamakina imatha kuchotsa mikwingwirima yaying'ono ndikupanga mawonekedwe agalasi. Amagwiritsidwa ntchito makamaka pa:
Kupukuta mafoni ndi zowonetsera za makompyuta;
Kupukuta bwino magalasi apamwamba a kuwala ndi magalasi a kamera;
Kukonza pamwamba pa zowonetsera za LCD ndi magalasi a TV;
Kukonza zinthu mwanzeru pogwiritsa ntchito galasi ndi magalasi owoneka bwino.
Poyerekeza ndi zipangizo zachikhalidwe zopukutira iron oxide, cerium oxide ili ndi liwiro lopukuta mofulumira, kuwala kwapamwamba, komanso nthawi yayitali yogwirira ntchito.
2. chothandizira utsi wa galimoto
Cerium oxide ndi gawo lofunika kwambiri mu ma catalyst a magalimoto atatu. Imatha kusunga ndikutulutsa mpweya bwino, kusintha kwa carbon monoxide (CO2), nitrogen oxides (NOₓ) ndi hydrocarbons (HC), motero imachepetsa kutulutsa mpweya woipa kuchokera ku utsi wa magalimoto ndikukwaniritsa miyezo yokhwima kwambiri ya chilengedwe.
3. Ma cell atsopano amphamvu ndi mafuta
Nanocerium oxide imatha kusintha kwambiri mphamvu ya mabatire komanso kulimba kwake ngati ma electrolyte kapena zinthu zina zomwe zili mu ma cell amafuta olimba a oxide (SOFC). Nthawi yomweyo, cerium oxide imasonyezanso magwiridwe antchito abwino kwambiri m'magawo a hydrogen catalytic decomposition ndi zowonjezera za lithiamu-ion batteries.
4. Zida zamagetsi ndi zowonjezera zagalasi
Monga chinthu chofunikira kwambiri pa zinthu zamagetsi, cerium oxide ingagwiritsidwe ntchito popanga ma capacitor, ma thermistors, zinthu zosefera za kuwala, ndi zina zotero. Ikawonjezeredwa pagalasi, imatha kutenga nawo mbali pakuchotsa utoto, kuwonjezera mawonekedwe, komanso kuteteza UV, ndikuwonjezera kulimba ndi mawonekedwe agalasi.
5. Zodzoladzola ndi zinthu zoteteza
Tinthu tating'onoting'ono ta nanocerium oxide timatha kuyamwa kuwala kwa ultraviolet ndipo nthawi zambiri timagwiritsidwa ntchito mu zodzoladzola zoteteza ku dzuwa ndi zinthu zosamalira khungu. Tili ndi ubwino wokhala ndi kukhazikika kwa zinthu zachilengedwe ndipo sitingamwe mosavuta ndi khungu. Nthawi yomweyo, timawonjezeredwa ku zokutira za mafakitale kuti tiwonjezere kukana dzimbiri komanso mphamvu zoletsa ukalamba.
6. Kulamulira zachilengedwe ndi mankhwala oyambitsa mankhwala
Cerium oxide imagwira ntchito yofunika kwambiri pakuyeretsa mpweya wotayidwa m'mafakitale, kusungunuka kwa zinyalala ndi madera ena. Mphamvu yake yayikulu yosinthira zinthu imapangitsa kuti igwiritsidwe ntchito kwambiri m'njira monga kusweka kwa mafuta ndi kupanga mankhwala.
IV. Chitukuko cha chitukuko
Ndi chitukuko chachangu cha mphamvu zatsopano, magetsi, kuteteza chilengedwe ndi mafakitale ena, kufunikira kwacerium oxideikupitiriza kukula. Malangizo akuluakulu a chitukuko mtsogolomu ndi awa:
Nano- ndi high-performance: kukonza malo enieni a pamwamba ndi momwe cerium oxide imagwirira ntchito kudzera mu nanotechnology.
Zipangizo zopukutira zobiriwira komanso zosawononga chilengedwe: kupanga ufa wopukutira wosawononga kwambiri komanso wobwezeretsa bwino zinthu kuti zigwiritsidwe ntchito bwino.
Kukula kwa mphamvu zatsopano: Pali chiyembekezo chachikulu pamsika wa mphamvu ya haidrojeni, maselo amafuta, ndi zinthu zosungira mphamvu.
Kubwezeretsanso zinthu: Kulimbikitsa kubweza ufa wopukuta zinyalala ndi chothandizira utsi kuti muchepetse zinyalala za zinthu.
V. Mapeto
Chifukwa cha ntchito yake yabwino kwambiri yopukuta, ntchito yake yothandiza komanso kukhazikika, cerium oxide yakhala chinthu chofunikira kwambiri pokonza magalasi, kukonza utsi wa magalimoto, zoumba zamagetsi zamagetsi ndi mafakitale atsopano amphamvu. Chifukwa cha kupita patsogolo kwa ukadaulo komanso kukula kwa kufunikira kwa mafakitale obiriwira, kuchuluka kwa momwe cerium oxide imagwiritsidwira ntchito kudzakulitsidwa kwambiri, ndipo mtengo wake wamsika ndi kuthekera kwake kopanga zinthu zidzakhala zopanda malire.
