Kev siv Cerium Oxide
Cerium Oxide, tseem hu ua Ceria, yog dav siv hauv iav, ceramics thiab catalyst manufacturing. Hauv kev lag luam iav, nws raug suav tias yog iav polishing tus neeg saib xyuas zoo tshaj plaws rau kev kho qhov muag polishing. Nws kuj yog siv los decolorize iav los ntawm kev khaws cov hlau hauv nws lub xeev ferrous. Lub peev xwm ntawm Cerium-doped iav los thaiv lub teeb ultraviolet yog siv hauv kev tsim cov iav kho mob thiab lub qhov rais aerospace. Nws kuj tseem siv los tiv thaiv cov polymers los ntawm kev tsaus ntuj hauv lub hnub ci thiab txhawm rau txo cov xim ntawm cov iav TV. Nws yog siv rau cov khoom siv kho qhov muag los txhim kho kev ua haujlwm. High purity Ceria kuj siv nyob rau hauv phosphors thiab dopant rau siv lead ua.
Cerium oxide, tseem hu ua ceria, yog ib qho kev sib xyaw ua ke ntawm cov ntsiab lus cerium thiab oxygen nrog cov tshuaj formula CeO2. Nws yog lub teeb daj lossis dawb hmoov, kuj ruaj khov nyob rau hauv ib txwm muaj. Cerium oxide muaj ntau yam kev siv, suav nrog:
1. Catalyst: Cerium oxide yog siv los ua ib qho catalyst hauv ntau cov txheej txheem kev lag luam, xws li hauv kev lag luam automotive rau catalytic converters kom txo cov emissions thiab rau zus tau tej cov roj hluavtaws.
2. Polishing tus neeg saib xyuas: Cerium oxide yog siv los ua polishing tus neeg saib xyuas rau iav thiab lwm yam ntaub ntawv. Nws zoo heev ntawm smoothing ntxhib nto thiab tshem tawm khawb.
3. Fuel additive: Nws tuaj yeem siv los ua cov khoom siv roj ntxiv los txhawb kev ua kom huv thiab ua kom muaj roj ntau dua.
4. Kev lag luam iav: Cerium oxide yog siv hauv kev lag luam iav los tsim cov iav zoo vim tias nws tuaj yeem ua rau cov iav refractive thiab txhim khu kev ruaj ntseg ntawm iav.
5. Solar cell ntau lawm: Cerium oxide yog siv los ua cov khoom siv rau kev tsim cov hnub ci. Zuag qhia tag nrho, cerium oxide muaj ntau daim ntawv thov thiab nws yog ib qho tseem ceeb nyob rau hauv ntau yam lag luam vim nws cov yam ntxwv tshwj xeeb.
6.siv raws li iav decolorizing tus neeg saib xyuas thiab cov iav polishing hmoov. Kuj tseem siv los ua cov khoom siv raw hauv kev ua hlau cerium. High purity Cerium dioxide yog ib qho tseem ceeb heev nyob rau hauv daim ntawv thov ntawm tsawg ntiaj teb cov ntaub ntawv fluorescent
