Hmoovactivated carbon(PAC) thiab granular activated carbon (GAC) yog ob hom activated carbon siv nyob rau hauv ntau yam dej thiab dej khib nyiab kev siv, nrog rau lwm yam lag luam xws li huab cua purification, zaub mov, thiab tshuaj. Lawv txhua tus muaj tib yam khoom siv yooj yim - cov pa roj carbon activated, muab los ntawm cov pa roj carbon ntau xws li txiv maj phaub plhaub, ntoo, lossis thee - tab sis lawv lub cev, kev siv, thiab cov txiaj ntsig sib txawv.
1. Particle loj:
PAC: PAC muaj cov hmoov av ua kom cov pa roj carbon zoo, feem ntau yog qhov loj ntawm 5 txog 50 microns (μm). Vim nws qhov me me me me, nws muaj thaj chaw siab heev uas sai sai nqus cov pa paug.
GAC: GAC, ntawm qhov tod tes, muaj cov khoom loj dua, feem ntau yog qhov loj ntawm 0.2 mus rau 5 millimeters (mm). Piv rau PAC, GAC muaj thaj tsam qis dua ntawm ib chav tsev tab sis raug dej rau lub sijhawm ntev dua vim nws qhov loj me me.
2. Deg cheeb tsam thiab adsorption muaj peev xwm:
PAC: Vim nws qhov loj me me, PAC muaj qhov tshwj xeeb ntawm thaj chaw ntau dua ib chav tsev piv rau GAC. Qhov no ua rau nws muaj txiaj ntsig tshwj xeeb ntawm kev tshem tawm me me thiab yaj cov kab mob xws li cov organic molecules thiab qee cov hlau hnyav.
GAC: GAC muaj thaj chaw tshwj xeeb qis dua ib chav tsev, tab sis nws ua rau qhov no nrog lub ntim loj dua. Nws yog feem ntau siv los tshem tawm cov khoom loj dua, colloids thiab cov kab mob microorganisms, thiab adsorb gases thiab vapors.
3. Lub sijhawm tiv tauj:
PAC: PAC muaj qhov nrawm nrawm nrawm vim nws qhov loj me me. Nws feem ntau yog siv rau cov txheej txheem ceev ceev adsorption thiab qhov twg yuav tsum tau siv sijhawm luv luv.
GAC: GAC muaj lub sijhawm sib cuag ntev dua nrog cov kua lossis roj nws ua haujlwm, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom qeeb dua, cov txheej txheem adsorption ntau dua.
4. Daim ntawv thov:
PAC: PAC feem ntau yog siv hauv kev kho dej hauv nroog kom tshem tawm cov teeb meem organic, saj thiab tsw ntxhiab, thiab qee yam khoom paug. Nws kuj tseem siv rau hauv kev lag luam xws li kev kho dej khib nyiab thiab kev tswj huab cua.
GAC: GAC muaj ntau yam kev siv, suav nrog kev kho dej hauv nroog, kho dej hauv av, kev kho dej khib nyiab, huab cua purification thiab vapor theem adsorption txheej txheem. Nws yog ntau yam thiab tuaj yeem kho tau ntau yam kab mob.
5. Recycling thiab pov tseg:
PAC: PAC feem ntau suav hais tias yog ib qho khoom siv ib zaug thiab feem ntau muab pov tseg tom qab siv vim tias nws cov khoom zoo yog qhov nyuaj rau rov tsim kho kom zoo.
GAC: GAC tuaj yeem rov tsim dua los ntawm ntau txoj hauv kev, xws li kev ua kom sov lossis tshuaj lom neeg, uas tuaj yeem ua kom nws lub neej muaj txiaj ntsig thiab txo qhov xav tau kev pov tseg. Qhov kev muaj peev xwm rov tsim dua tshiab ua rau GAC qhov kev xaiv ruaj khov dua hauv qee yam kev siv.
6. Nqi:
PAC: Ntawm chav tsev, PAC feem ntau siv nyiaj ntau dua li GAC, tab sis tej zaum yuav xav tau kev hloov ntau zaus, ua rau cov nqi khiav hauj lwm ntev dua.
GAC: GAC tej zaum yuav muaj tus nqi pib ntau dua, tab sis tuaj yeem ua rau cov nqi txuag lub sij hawm vim nws cov khoom siv dua tshiab thiab kev ua neej ntev.
Hauv cov ntsiab lus, kev xaiv ntawm PAC thiab GAC nyob ntawm cov ntawv thov tshwj xeeb, dej zoo, thiab cov hom phiaj kho. PAC yog qhov tsim nyog rau kev nqus sai ntawm cov kab mob me me, thaum GAC muab sijhawm sib cuag ntev dua thiab siv tau ntau yam rau ntau yam kev siv. Qhov kev txiav txim siab no yuav tsum txiav txim siab txog yam xws li qhov yuav tsum tau muaj ntawm thaj chaw, lub sijhawm tiv tauj, muaj peev xwm rov tsim dua tshiab, thiab tag nrho cov nqi
