Activated Alumina Rau Kev Kho Dej
Khoom Taw Qhia
Cov khoom yog cov khoom siv dawb, kheej kheej kheej kheej nrog cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab, insoluble hauv dej thiab ethanol. Qhov loj me me yog qhov sib xws, qhov saum npoo yog du, lub zog ntawm lub zog yog siab, lub peev xwm ntawm cov dej nqus dej muaj zog thiab lub pob tsis sib cais tom qab nqus dej.
Qhov loj me me tuaj yeem yog 1-3mm, 2-4mm / 3-5mm lossis txawm me me xws li 0.5-1.0mm.Nws muaj qhov sib cuag loj dua nrog cov dej thiab thaj chaw tshwj xeeb saum npoo siab tshaj 300m² / g, nws muaj qhov loj ntawm microspores thiab tuaj yeem ua kom muaj zog adsorption thiab siab defluorination ntim rau fluorinnion hauv dej.
Alumina rau hydrogen peroxide muaj ntau txoj hauv kev capillary thiab thaj chaw loj, uas tuaj yeem siv ua adsorbent, desiccant thiab catalyst. Nyob rau tib lub sijhawm, nws kuj tau txiav txim siab raws li qhov 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-dej sib sib zog nqus desiccant thiab adsorbent rau adsorbing polar molecules. .
Nyob rau hauv qee qhov kev ua haujlwm thiab kev tsim kho dua tshiab, nws qhov tob kom qhuav yog siab npaum li cov dej lwg taw tes hauv qab -40 ℃, thiab nws yog cov khoom siv tau zoo rau kev ziab ntawm cov dej sib sib zog nqus. Nws yog dav siv nyob rau hauv roj thiab kua theem ziab ntawm petrochemical kev lag luam, ziab ntawm textile kev lag luam, oxygen ntau lawm kev lag luam thiab tsis siv neeg ntsuas cua, siab viav vias adsorption nyob rau hauv huab cua sib cais kev lag luam, thiab lwm yam. yog heev haum rau heatless regeneration li. Alumina rau hydrogen peroxide yog dawb kheej kheej porous hais nrog cov khoom me me, du nto, siab txhua yam muaj zog thiab muaj zog hygroscopicity. Nws yog ua los ntawm high-purity alumina los ntawm kev npaj thiab catalytic tiav. Nws tuaj yeem siv los ua cov tshuaj fluoride tshem tawm rau cov dej muaj fluoride siab, ua rau nws cov molecular adsorbent nrog rau thaj tsam loj loj. Thaum pH tus nqi thiab alkalinity ntawm cov dej nyoos tsawg, lub peev xwm tshem tawm fluorine yog siab, ntau dua 3.0mg / g. Nws tuaj yeem siv rau kev tshem tawm fluorine, tshem tawm arsenic, dej phwj decolorization thiab deodorization ntawm cov dej haus thiab cov khoom lag luam.

Daim ntawv thov / ntim
Nws tuaj yeem siv los ua tus neeg sawv cev defluorination rau dej. Tshwj xeeb tshaj yog thaum tus nqi PH thiab alkalinity ntawm cov dej yog loner, qhov ntim defluorination tuaj yeem siab dua 4.0mg / g. Nws tuaj yeem siv los tshem tawm arsenic hauv cov dej haus.
25kg woven hnab / 25kg ntawv board nruas / 200L hlau nruas los yog ib tus neeg thov.
