Decoloring Tus neeg saib xyuasyog ib qho tshuaj siv los tshem tawm cov xim ntawm ib yam khoom. Nws cov txheej txheem ua haujlwm yog ua tiav los ntawm cov tshuaj tiv thaiv tshuaj, adsorption lossis flocculation. Raws li nws cov txheej txheem, tus neeg sawv cev decoloring tau muab faib ua oxidation decoloring tus neeg sawv cev, tus neeg sawv cev decoloring thiab flocculation decoloring tus neeg sawv cev.
- Oxidation decolorizers siv cov khoom muaj zog oxidizing xws li hydrogen peroxide thiab chlorine kom hnov mob nrog pab pawg xim thiab ua kom lawv cov qauv molecular, yog li tshem tawm cov xim.
- Adsorption decolorizer, zoo li cov pa roj carbon monoxide lossis active aluminium oxide, yog tsim los adsorb xim xim hauv cov dej khib nyiab los ntawm nws tus kheej cov qauv ntxeem tau kom tshem tawm chroma.
- Raws li ob hom decolorizers no muaj qee qhov kev txwv, flocculation decolorizers tau dhau los ua cov khoom tseem ceeb ntawm decolorization.
Flocculation decolorizers yog cationic polymer tebchaw nrog ntau lub zog xws li decolorization, flocculation, thiab COD decomposition. Lawv hnov mob nrog cov xim xim hauv cov dej khib nyiab, feem ntau yog los ntawm hluav taws xob nruab nrab, hydrogen bonding, adsorption bridging thiab lwm yam txheej txheem, los tsim cov flocculants ruaj khov uas raug tshem tawm los ntawm nag lossis daus.
Vim nws txoj kev ua tau zoo heev, decolorizer yog dav siv hauv textile, ntawv ua, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.
Textile thiab Dyeing Industry
Nyob rau hauv cov txheej txheem ntawm textile printing thiab dyeing, vim muaj ntau yam dyes thiab complex txheej txheem, cov dej khib nyiab feem ntau muaj ntau cov xim uas nyuaj rau degrade. Txawm hais tias acidic, alkaline lossis disperse dyes, peb cov decolorizer tuaj yeem ua tiav cov nyhuv decolorization zoo los xyuas kom meej cov qauv tso tawm.
Kev lag luam ntawv
Papermaking wastewater yog ib qho tseem ceeb ntawm cov dej paug, feem ntau los ntawm ntau theem ntawm cov txheej txheem tsim ntawv, suav nrog cov dej dub los ntawm pulping, bleaching dej khib nyiab, thiab dej dawb los ntawm daim ntawv rhiav. Lawv muaj ntau cov kuab paug thiab tshem tawm cov khib nyiab, thiab muaj COD siab heev. Decolorizers yog siv los kho cov dej khib nyiab los ntawm kev sib sau cov khib nyiab thiab cov khoom zoo rau hauv flocs, ua kom yooj yim rau cov txheej txheem decolorization.
Lwm Cov Kev Lag Luam
Ntxiv nrog rau kev lag luam textile thiab ntawv, decolorizers kuj tau siv dav hauv kev kho dej khib nyiab ntawm number case, tawv, roj hmab, tshuaj thiab lwm yam lag luam.
Muaj decoloring tus neeg saib xyuas ua lub luag haujlwm tseem ceeb hauv kev kho dej, uas tuaj yeem tsis tsuas yog tshem tawm cov xim hauv dej, tab sis kuj txhim kho cov dej zoo. Yog xav paub ntxiv, txais tos hu rau peb. Peb muaj ntau xyoo ntawm kev koom tes nrog ib tug xov tooj ntawm dej decoloring neeg sawv cev manufacturers kom paub meej cov khoom zoo thiab cov nqi sib tw.
