Cov pa roj carbon activated lossis activated charcoal yog ib qho ntawm cov khoom siv dav tshaj plaws hauv kev lag luam kho dej, uas feem ntau yog ua los ntawm cov hmoov thiab granular. Cov ntawv thov tseem ceeb ntawm cov pa roj carbon activated yog cais cov pigments, tsw, saj thiab chlorine los ntawm cov dej hauv cov khoom noj thiab tshuaj lom neeg kev lag luam, thoob dej yug ntses, hauv tsev.
Vim tias cov txheej txheem ua kom muaj zog yog cov txheej txheem microscopic, uas yog, qhov yaig ntawm ntau cov molecular carbides yog taw tes yaig, ua rau muaj ntau qhov me me ntawm cov pa roj carbon activated.
Lub hom phiaj tseem ceeb ntawm kev siv cov pa roj carbon activated hauv kev lag luam khoom noj yog tshem tawm cov xim thiab lawv cov precursors, kho cov tshuaj tsw qab, deodorize, tshem tawm cov colloids, tshem tawm cov khoom uas cuam tshuam crystallization, thiab txhim kho cov khoom ruaj khov.
Kev siv cov activated carbon hauv decolorization
Qab Zib decolorization yog daim ntawv thov qub tshaj plaws ntawm cov pa roj carbon activated. Nyob ib ncig ntawm lub xyoo pua 18th, pob txha charcoal twb tau siv rau decolorization nyob rau hauv kev lag luam qab zib, thiab txij li thaum lub xyoo pua 20th, pob txha charcoal tau maj mam hloov los ntawm activated carbon.
Cov kua qab zib muaj ntau yam xim, xws li melanin, caramel, thiab hlau complex, ntawm cov uas melanin muaj feem cuam tshuam rau cov xim muaj nuj nqis ntawm cov suab thaj. Cov pa roj carbon activated muaj cov qauv tsim cov pore zoo nrog coexisting macropores, mesopores, thiab micropores, uas ua rau nws tshem tawm ntau yam xim, thiab nws cov nyhuv adsorption ntawm cov xim dub zoo li cov tshuaj tshwj xeeb, ua rau nws siv dav.
Ntxiv nrog rau decolorization, cov pa roj carbon activated tseem tuaj yeem tshem tawm cov colloid thiab nquag impurities nyob rau saum npoo ntawm cov kua qab zib, yog li txhawm rau ua kom lub ntsej muag nruj ntawm cov kua qab zib, txo cov viscosity, txo cov npuas dej thaum lub sij hawm evaporation, txhim kho kev ceev ceev, thiab txhim kho cov nyhuv sib cais ntawm cov suab thaj siv lead ua thiab molasses.
Ob lub hmoov activated carbon thiab granular activated carbon yuav siv tau rau qab zib decolorization.
Powdered activated carbon muaj thaj tsam loj ntawm ib chav tsev ntim thiab tuaj yeem ua tiav hauv lub sijhawm luv luv, ua kom yooj yim rau kev hloov pauv hauv cov khoom siv tshuaj. Kev ua haujlwm feem ntau tsis sib xws thiab muaj qhov ntsuas me me.
Granular activated carbon tuaj yeem sau rau hauv kab adsorption rau kev ua haujlwm tas mus li thiab tuaj yeem rov ua dua los ntawm kev tsim dua tshiab, ua rau nws tsim nyog rau kev tsim khoom loj. Qhov zoo ntawm cov kua qab zib kho los ntawm txoj kev no yog qhov sib xws thiab tuaj yeem txo cov nqi tsim khoom.
Cov ntaub ntawv ua kom cov pa roj carbon activated muaj cov teebmeem tshwj xeeb rau kev ua kom huv ntawm huab cua vim lawv cov qauv tshwj xeeb, tab sis kuj tseem yuav muaj qhov sib txawv ntawm cov khoom sib txawv thiab qhov ntau thiab tsawg. Tiv tauj peb thiab peb yuav muab cov khoom tsim nyog rau koj.
