Impregnated activate carbon yog ib cov khoom ua haujlwm uas txhim kho adsorption kev ua tiav los ntawm kev hloov kho tshuaj lom neeg. Nws cov txheej txheem ntau lawm feem ntau muaj plaub kauj ruam tseem ceeb: Kev hloov kho raw, impregnation hloov kho, kom qhuav thiab ua kom qhuav, thiab kev sim tshuaj, thiab kev sim tshuaj.
Thaum lub sij hawm ua cov khoom siv ua tiav, nws yog ib qho tsim nyog los tshuaj ntsuam xyuas cov pa roj carbon monoxide nrog ntau dua li 800mg / g thiab thaj chaw tshwj xeeb ntawm> 1000m² / g. Tom qab cov hmoov tshauv yog muab tshem tawm los ntawm cov kua qaub ntxuav, nws tau ntxuav nrog dej kom txog thaum nruab nrab thiab qhuav rau cov ntsiab lus noo noo ntawm tsawg dua 3%. Hauv Impregnation Cov theem hloov kho, cov kev daws teeb meem sib txawv tau npaj raws li daim phiaj thov: rau alkaline impregnation, 20% -40% kua roj yog siv; Acidic Ipric impregation siv tau 40% -60 phosphoric kua qaub; Txog cov laj thawj tshwj xeeb xws li desulfurization, poov tshuaj iodide ntxiv.
Sib tov cov pa roj carbon nrog cov kua tsis sib xws hauv 1: 1 txog 1: 3, thiab do ntawm 60-80℃rau 1-3 teev kom tiav cov impregnation. Tom qab, ua ntej kom qhuav ntawm 100-120℃thiab cremation nyob rau hauv ib qho inert cua ntawm 130-180℃rau 1-2 teev yog nqa tawm. Txhawm rau txhim kho kev ua tau zoo, lub mesoporous qauv tuaj yeem ua kom tau thiab ua kom nrov los ntawm chav ntawm 800-900 degree.
The finished products need to be tested for indicators such as iodine value and methylene blue adsorption value. For desulfurization products, the H₂S penetration capacity (>30% wt) tseem yuav tsum tau sim. Cov ntaub ntawv no muaj VOCs raug tshem tawm ntawm ntau tshaj 95% hauv kev kho cov roj uas muaj kuab lom roj thiab cov ntawv tshaj tawm tshiab ntawm 99.2% rau cov ntaub ntawv pov tseg hauv electroplating wastewater. Nws yog cov khoom siv ua haujlwm tseem ceeb hauv kev tswj hwm ib puag ncig.
