Ua kom Alumina Siv rau Kev Kho Dej
Kev Taw Qhia Txog Khoom
Cov khoom no yog ib yam khoom dawb, kheej kheej uas muaj qhov ntxeem tau nrog cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis yaj hauv dej thiab ethanol. Qhov loj me ntawm cov khoom yog sib npaug, qhov chaw du, lub zog kho tshuab siab, lub peev xwm nqus dej noo tau zoo thiab lub pob tsis tawg tom qab nqus dej.
Qhov loj me ntawm cov khoom me me tuaj yeem yog 1-3 hli, 2-4 hli / 3-5 hli lossis me dua xws li 0.5-1.0 hli. Nws muaj thaj chaw sib cuag loj dua nrog dej thiab thaj chaw tshwj xeeb siab dua 300m² / g, nws muaj ntau cov microspores thiab tuaj yeem ua kom muaj zog adsorption thiab muaj peev xwm defluorination ntau rau fluorinnion hauv dej.
Alumina rau hydrogen peroxide muaj ntau cov capillary channels thiab thaj chaw loj, uas tuaj yeem siv ua adsorbent, desiccant thiab catalyst. Tib lub sijhawm, nws kuj tau txiav txim siab raws li polarity ntawm cov khoom adsorbed. Nws muaj kev sib raug zoo rau dej, oxides, acetic acid, alkali, thiab lwm yam. Activated alumina yog ib hom micro-water tob desiccant thiab adsorbent rau adsorbing polar molecules. .
Nyob rau hauv qee qhov kev ua haujlwm thiab kev rov ua dua tshiab, nws qhov tob ziab yog siab txog qhov kub ntawm cov dej noo hauv qab -40 ℃, thiab nws yog ib qho desiccant zoo rau kev ziab tob ntawm cov dej me me. Nws yog dav siv rau hauv kev ziab roj thiab kua theem ntawm kev lag luam petrochemical, kev ziab ntawm kev lag luam textile, kev lag luam tsim oxygen thiab cua ntsuas tsis siv neeg, kev nqus siab hauv kev lag luam sib cais cua, thiab lwm yam. Vim yog qhov kub siab ntawm cov txheej adsorption monomolecular, nws yog qhov tsim nyog heev rau cov khoom siv rov ua dua tshiab tsis muaj cua sov. Alumina rau hydrogen peroxide yog cov khoom me me dawb nrog qhov loj me sib xws, nto du, lub zog kho tshuab siab thiab hygroscopicity muaj zog. Nws yog ua los ntawm alumina siab-purity los ntawm kev npaj kev tshawb fawb thiab kev ua tiav catalytic. Nws tuaj yeem siv ua cov tshuaj fluoride tshem tawm rau cov dej fluoride siab, ua rau nws yog cov tshuaj molecular adsorbent nrog thaj chaw loj heev. Thaum tus nqi pH thiab alkalinity ntawm cov dej nyoos qis, lub peev xwm tshem tawm fluorine siab, ntau dua 3.0mg / g. Nws tuaj yeem siv rau kev tshem tawm fluorine, tshem tawm arsenic, dej phwj decolorization thiab deodorization ntawm dej haus thiab cov khoom siv kev lag luam.

Daim Ntawv Thov/Ntim Khoom
Nws siv tau ua tus neeg sawv cev defluorination rau dej. Tshwj xeeb tshaj yog thaum tus nqi PH thiab alkalinity ntawm cov dej yog qhov tsis sib xws, qhov ntim defluorination tuaj yeem siab dua 4.0mg / g. Nws tuaj yeem siv los tshem tawm arsenic hauv cov dej haus.
25kg hnab ntaub/25kg ntawv nruas/200L hlau nruas lossis ib tus neeg siv khoom thov.
