Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooCerium Carbonate Loj Me Me.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Cerium Carbonate Loj Me Me tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Cerium Carbonate Loj Me Me tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomCerium Carbonate Loj Me Me ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalyst rau kev lag luam tshuaj lom neeg: Cov khoom loj cerium carbonate yog cov khoom siv tseem ceeb rau kev npaj cov tshuaj catalysts peb txoj kev tso pa tawm hauv tsheb. Los ntawm kev kub siab calcination, nws tuaj yeem hloov mus ua cerium oxide nrog lub peev xwm cia oxygen siab, yog li ua kom zoo txhawb cov tshuaj catalytic purification ntawm carbon monoxide, hydrocarbons, thiab nitrogen oxides.

Tus Neeg Sawv Cev Tshem Tawm Phosphorus Zoo: Raws li qhov sib raug zoo ntawm cerium ions thiab phosphate ions, cov khoom loj cerium carbonate tuaj yeem siv ua tus neeg sawv cev tshem tawm phosphorus rau kev kho dej thiab kho cov dej eutrophic. Nws cov khoom loj ua rau muaj kev ua haujlwm zoo dua hauv kev siv, pab txhawb kev sib cais thiab rov qab tau, thiab txo qhov kev sib sau ua ke ntawm phosphorus hauv cov dej khib nyiab mus rau qib qis heev (piv txwv li, txij li 0.55 mg-P / L rau≤0.03 mg-P/L).

Cov Khoom Siv Ua Los Ntawm Av nplaum thiab Cov Khoom Siv Ua Kom Sib Txhuam: Cov cerium carbonate loj yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv ua los ntawm av nplaum tshwj xeeb (xws li cov khoom siv ua los ntawm av nplaum hluav taws xob) thiab cov hmoov ua kom sib txhuam zoo. Nws cov khoom me me dua pab ua kom tiav qhov chaw ua kom sib txhuam du, uas yog qhov tseem ceeb hauv kev ua kom sib txhuam tshuaj lom neeg (CMP) ntawm cov iav kho qhov muag thiab cov wafers semiconductor. Nws kuj tseem siv tau ua cov khoom ntxiv rau hauv cov hlau nplaum tawv kom txhim kho kev ua tau zoo ntawm cov khoom.

Cov tshuaj synthesis intermediates: Raws li ib qho tseem ceeb precursor rau cerium compounds, cov cerium carbonate loj-grained yog siv los synthesize ntau yam cerium ntsev (xws li cerium nitrate, cerium chloride, thiab lwm yam) thiab thaum kawg los npaj cov siab-purity cerium oxide. Los ntawm kev tswj hwm nruj me ntsis cov xwm txheej nag (xws li qhov concentration ntawm cov kua tsis tshua muaj av, qhov kub ntawm cov tshuaj tiv thaiv, thiab lub sijhawm laus), qhov loj me ntawm cov khoom tuaj yeem hloov kho tau (qhov loj me ntawm cov khoom nruab nrab D50 tuaj yeem ncav cuag kwv yees li 150μm), ua tau raws li cov kev cai tshwj xeeb ntawm ntau daim ntawv thov downstream rau qhov loj me ntawm cov khoom siv raw.
