Kev yuav khoom ntawm cov pa roj carbon activated yuav tsum tau ua tib zoo xav txog ntau yam los xyuas kom meej qhov kev xaiv ntawm cov khoom tsim nyog. Xaiv txoj cai activated carbon yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam rau qhov kawg ntawm daim ntawv thov. Cov pa roj carbon activated tsis yog homogeneous khoom; nws qhov kev ua tau zoo sib txawv heev nyob ntawm cov khoom siv raw, kev tsim khoom, thiab lwm yam. Yog li, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov xwm txheej tshwj xeeb ntawm daim ntawv thov thiab lub hom phiaj cov pa phem kom ua tiav qhov zoo tshaj plaws sib npaug ntawm tus nqi thiab kev ua haujlwm.
Lub hauv paus tseem ceeb uas yuav tsum xav txog hauv kev yuav khoom ntawm cov pa roj carbon activated yog lub hom phiaj ntawm daim ntawv thov. Cov pa roj carbon activated feem ntau yog siv rau adsorbing impurities nyob rau hauv gaseous los yog kua theem, tab sis cov hom phiaj nyob rau hauv txawv scenarios yog txawv kiag li. Xws li, yog tias nws yog siv rau kev kho dej, lub hom phiaj yog tshem tawm cov tshuaj chlorine seem, txhim kho saj thiab xim, thiab tom qab ntawd particle-raws li cov pa roj carbon activated ua los ntawm qib siab -cov thee lossis txiv maj phaub plhaub feem ntau yog qhov kev xaiv zoo, vim nws cov qauv pore tsim tshwj xeeb yog zoo ntawm adsorbing me me molecules ntawm cov organic tshuaj hauv dej. Txawm li cas los xij, yog tias lub hom phiaj yog los ntxuav cov huab cua thiab adsorb volatile organic tebchaw xws li formaldehyde thiab benzene, ces txiv maj phaub-raws li lossis ntoo-raws li cov pa roj carbon monoxide yuav muaj qhov zoo dua, vim nws muaj cov qauv microporous nplua nuj, uas yog tsim nyog rau kev ntes cov roj molecules. Rau kev lag luam tshwj xeeb xws li kub refining, muaj qhov yuav tsum tau muaj zog thiab adsorption yam ntxwv, thiab tshwj xeeb almond plhaub carbon los yog thee -raws li carbon yuav raug xaiv. Yog li ntawd, kom paub meej tias "qhov twg nws siv thiab nws tshem tawm dab tsi" yog thawj kauj ruam.
Tom qab txiav txim siab cov kev taw qhia dav dav, qhov ntsuas lub cev thiab tshuaj lom neeg ntawm cov pa roj carbon activated nws tus kheej dhau los ua tus yuam sij rau kev tshuaj ntsuam. Nyob rau hauv cov nqe lus ntawm lub cev daim ntawv, muaj mas hmoov activated carbon thiab granular activated carbon. Powdered activated carbon yog haum rau cov xwm txheej uas xav tau sai sai adsorption thiab ib qho ntxiv - lub sij hawm ntxiv, xws li kev kho dej thaum muaj xwm txheej ceev lossis ua ib qho ntxiv hauv cov txheej txheem ntws, tab sis nws tsis tuaj yeem rov qab siv dua hauv lub txaj ruaj khov. Granular activated carbon yog tsim los tsim ib lub txaj adsorption ruaj khov rau kev nruam los yog ib nrab - tsis tu ncua dynamic filtration, feem ntau pom muaj nyob rau hauv tsev purifiers los yog industrial filtration devices. Nws qhov zoo dua yog tias nws tuaj yeem rov ua dua thiab muaj lub neej ua haujlwm ntev dua. Ntau nyob rau hauv - qhov ntsuas qhov tob suav nrog tus nqi iodine, carbon tetrachloride adsorption tus nqi, thiab methylene xiav tus nqi, uas feem ntau sawv cev rau lub peev xwm adsorption ntawm cov pa roj carbon activated rau txawv - cov pa phem molecular. Piv txwv li, tus nqi iodine siab feem ntau txhais tau hais tias kev ua haujlwm zoo tshaj plaws rau cov khoom me me (xws li cov tshuaj chlorine residual); thaum tus nqi methylene xiav tuaj yeem cuam tshuam zoo dua nws cov peev xwm adsorption rau cov khoom loj dua (xws li qee cov dyes, organic tshuaj). Cov kev ntsuas tsis zoo no yog lub hauv paus tseem ceeb rau kev txiav txim siab qhov zoo ntawm cov pa roj carbon activated.
Thaum kawg, kev lag luam thiab kev nyab xeeb hauv kev yuav khoom siv hluav taws xob kuj tseem yog qhov tseem ceeb. Thaum ua tau raws li cov kev xav tau ntawm kev ua tau zoo, nws yuav tsum tau ua tib zoo xav txog cov nqi tsev, hloov zaus, thiab kev siv hluav taws xob los ntawm kev ua haujlwm tsis zoo thoob plaws hauv lub neej. Nyob rau tib lub sijhawm, kev nyab xeeb yog qhov tseem ceeb heev, tshwj xeeb tshaj yog thaum siv hauv cov dej haus lossis kev ua zaub mov, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom lag luam uas ua raws li cov khoom noj muaj feem xyuam - qib kev nyab xeeb, xyuas kom lawv tsis muaj cov khoom tsis zoo thiab tsis tso cov khoom tsis zoo rau cov dej uas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. Kev xaiv lub luag haujlwm yog txhawm rau nrhiav qhov chaw ruaj khov tshaj plaws ntawm kev ua haujlwm, nqi, thiab kev nyab xeeb. Los ntawm qhov kev ntsuam xyuas zoo li no, peb tuaj yeem phim qhov "tsim nyog" hom ntawm cov pa roj carbon activated rau cov kev xav tau tshwj xeeb, tso cai rau nws cov kev ua tau zoo tshaj plaws.
