Daim Ntawv Thov ntawm Creium oxide
Creium ox oxide, tseem hu ua Ceria, yog qhov sib txuas ua ke ntawm cov ntsiab lus cerium thiab oxygen nrog tshuaj lom neeg CEO2. Nws yog lub teeb daj daj lossis dawb hmoov, kwv yeesvmob ruaj khov nyob rau hauv ib txwm muaj. Creium Oxide muaj ntau cov ntawv thov, suav nrog:
1. Carealyst: Cov roj ntsha cerium yog siv los ua cov txheej txheem ntawm ntau cov txheej txheem muaj, xws li nyob rau hauv kev lag luam tsheb catissions kom txo cov pa hluav taws xob catisetions.
2. Cov neeg sawv cev polishing: CineCium oxide yog siv los ua polishing tus neeg sawv cev rau iav thiab lwm yam khoom siv. Nws yog qhov ua tau zoo ntawm kev ntxhib cov chaw thiab tshem cov khawb.
3. Roj Additive: Nws tuaj yeem siv los ua roj av ntxiv los txhawb cov tshuaj ntxuav kom huv thiab ntau dua cov roj.
4. Kev lag luam iav: Cov pa yeeb nkab tau siv rau hauv cov iav iav tsim cov iav zoo vim tias nws tuaj yeem nce cov teeb meem tsis tuaj yeem thiab txhim kho lub durability ntawm lub khob.
5. Hnub ci Cell Ntau Lawm: CATINE OXIDE siv los ua cov khoom siv txheej rau kev tsim khoom ntawm cov hlwb solar. Zuag qhia tag nrho, caleium oxide muaj ntau cov ntawv thov thiab nws yog ib qho kev sib xyaw ua ke hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb.
6.uilation raws li cov iav decolorizing tus neeg sawv cev thiabKhob Polishing HmoovCov. Kuj tseem siv los ua cov khoom siv raw ua hauv kev ua hlau cerium. Kev Purity High Cerium Dioxide yog qhov tseem ceeb hauv cov ntawv thov tsis tshua muaj lub ntiaj teb fluorescent
