Muab xam los ntawm huab hwm coj, qhov nruab nrab tib neeg yog ua los ntawm 18.5% carbon. Yog tias koj tsis suav nrog oxygen, koj muaj cov pa roj carbon ntau dua li lwm cov khoom. Cov pa roj carbon kuj tseem siv zog rau peb lub ntiaj teb los ntawm cov thee thiab roj thiab nws yog ib qho ntawm cov lim dej zoo tshaj plaws uas peb muaj. Yog tsis muaj cov pa roj carbon, lub neej yuav zoo nkauj sib txawv, lossis ntau dua, tej zaum yuav tsis muaj nyob.
Tib neeg tau pom ntau txoj hauv kev los siv cov pa roj carbon monoxide kom haum peb cov kev xav tau ntau, suav nrog kev lim dej.
Ib qho kev tshawb pom tseem ceeb tshaj plaws uas peb tau ua yog tias ua rau thaj tsam ntawm cov pa roj carbon ntau ntxiv - ua kom nws - ua rau nws zoo dua ntawm kev kho dej. Peb kuj tau kawm tias impregnating carbon nrog lwm cov ntsiab lus tuaj yeem pab tshem tawm cov kab mob tshwj xeeb, xws li cov lim dej ua kom muaj pa.
Activated Carbon yog dab tsi?
Cov pa roj carbon activated, los yog activated charcoal, yog cov pa roj carbon monoxide kho kom ua kom nws qhov chaw loj tuaj. Nrog rau thaj tsam ntau dua, cov pa roj carbon activated tuaj yeem nqus cov kab mob ntau dua li qhov nws ua tau. Qee qhov xwm txheej, cov tshuab lim dej lim dej muaj ntau dua 4,200 square metres ntawm thaj chaw ib gram.
Cov pa roj carbon activated tuaj yeem tsim los ntawm cov khoom siv cua sov super zoo li ntoo, fibers, thiab thee yam tsis muaj oxygen. Nws tau sov dua zaum ob hauv qhov chaw oxygenated thaum raug nitrogen lossis argon.
Qhov no tshwj xeeb, ob-kauj ruam kev kub hnyiab ua rau cov pa roj carbon ntau ntxeem tau, uas ua rau nws nce qhov chaw. Raws li cov dej hla dhau thiab nyob ib ncig ntawm qhov ntxeem tau ntawm cov pa roj carbon activated, ntau cov kab mob kis tau mus rau hauv thiab kaw, tawm hauv koj lub tshuab nqus dej.
Cov pa roj carbon activated tau siv dav vim tias nws pheej yig thiab muaj ntau, nws yooj yim heev hauv txoj kev nws ua haujlwm, thiab nws zoo heev ntawm kev tshem tawm qee yam kab mob xws li chlorine, uas ua rau koj cov dej tsis zoo.
Ib qho ntawm feem ntau siv ntau yam hauv cov lim dej yog txiv maj phaub plhaub carbon.
Cov kab mob dab tsi puas ua kom cov pa roj carbon lim dej tshem tawm?
Cov txiaj ntsig ntawm activated carbon lim yog tias lawv tshem tawm lossis txo ntau yam kab mob los ntawm cov dej haus. Cov no suav nrog:
Chlorine
Cov tshuaj chlorine yog cov tshuaj tua kab mob ntau tshaj plaws siv hauv cov dej hauv pej xeem. Thaum nws yog qhov zoo heev ntawm kev tua cov kab mob hauv koj cov dej, nws tuaj yeem qhuav koj cov tawv nqaij thiab ua rau koj cov dej saj thiab tsw zoo li lub pas dej da dej. Nws kuj tsim cov tshuaj tua kab mob txaus ntshai byproducts.
Chloramines
Cov tshuaj tua kab mob no yog tsim los ntawm kev sib xyaw chlorine thiab ammonia. Nws yog feem ntau siv hauv cov kav dej hauv nroog vim tias nws kav ntev dua li cov tshuaj chlorine. Zoo li chlorine, chloramines tuaj yeem ua rau tawv nqaij khaus thiab teeb meem ua pa thiab ua rau cov khoom siv organic hauv dej los tsim cov tshuaj tua kab mob phem xws li trihalomethanes.
Trihalomethanes (THMs)
Cov tshuaj sib xyaw no tuaj yeem tsim tau thaum siv cov tshuaj chlorine thiab chloramines los tua cov dej. THMs tau txuas mus rau ntau yam teeb meem kev noj qab haus huv, suav nrog mob qog noj ntshav thiab teeb meem kev loj hlob. activated carbon media tshem tawm trihalomethanes thiab lwm yam tshuaj tua kab mob byproducts.
Hydrogen sulfide
Yog tias koj tau xav paub tias yog vim li cas dej zoo tsw tsw phem, hydrogen sulfide yog koj cov lus teb. Cov roj no uas tsw zoo li cov qe lwj tuaj yeem ua rau koj cov kav hlau thiab cov khoom siv.
Tshuaj tua kab thiab tshuaj tua kab mob
Cov tshuaj txaus ntshai no feem ntau ua rau cov khoom siv dej hauv pej xeem thiab ntiag tug vim lawv tau siv ntau heev hauv kev ua liaj ua teb thiab kev tu nyom. activated carbon media pab koj tshem tawm ntau cov tshuaj phem no los ntawm koj cov dej.
Hlau thiab manganese
Cov hlau no ua rau koj cov khaub ncaws thiab khoom siv thiab tuaj yeem txhaws koj cov kav dej. Yog tias koj muaj dej tawv, cov zaub mov no tuaj yeem ua rau nws tsis zoo. Qhov tseeb, yog tias koj tuaj yeem tshem tawm cov hlau ua ntej nws tsoo koj cov dej softener, koj tuaj yeem ua kom nws ua tau zoo thiab txuag tau qee cov nyiaj ntsev.
Volatile Organic Compounds (VOCs)
Cov no yog cov tshuaj organic uas tuaj yeem evaporate rau hauv huab cua ntawm chav tsev kub. VOCs yog nyob rau hauv kev lag luam thiab cov khoom siv hauv tsev, thiab lawv tuaj yeem cuam tshuam kev noj qab haus huv tsis zoo nrog rau lub sijhawm ntev. Qee qhov VOCs uas tau txais cov pa roj carbon tshem tawm yog:
- Benzene: Lub npe hu ua carcinogen no yog cov kua tsis muaj xim uas siv los tsim cov yas, hluavtaws fibers, thiab roj hmab. Kev raug ntau ntau tuaj yeem ua rau muaj ntau yam teeb meem kev noj qab haus huv.
- Toluene: Kev raug Toluene tuaj yeem ua rau muaj teeb meem kev noj qab haus huv xws li mob taub hau thiab kiv taub hau. Cov tshuaj tsis muaj xim tsis muaj xim no yog siv rau hauv kev tsim cov roj av, cov kuab tshuaj, thiab lwm yam khoom lag luam.
- Xylene: Ib qho nyuaj-rau-nrhiav cov kuab tshuaj uas siv los tsim cov roj hmab thiab cov yas, kev raug xylene tuaj yeem ua rau mob taub hau, kiv taub hau, thiab lwm yam teeb meem kev noj qab haus huv.
- Trichlorethylene (TCE): Lwm yam tsis muaj xim muaj kuab tshuaj, TCE yog siv los tsim cov tub yees, cov nplaum, thiab lwm yam khoom lag luam. Kev raug TCE tuaj yeem ua mob rau koj lub siab thiab lub raum thiab ua rau mob qog noj ntshav.
- Perchlorethylene (PCE): PCE yog cov kua tsis muaj xim uas siv los ua cov kuab tshuaj ntxuav qhuav thiab lwm yam khoom lag luam. Kev cuam tshuam rau PCE tuaj yeem ua rau lub siab thiab lub raum puas, thiab nws tau txuas rau mob qog noj ntshav.
- Dichlorobenzene: Zoo ib yam li lwm tus hauv daim ntawv teev npe no, raug rau dichlorobenzene tuaj yeem ua rau mob taub hau, kiv taub hau, thiab ntau yam teeb meem kev noj qab haus huv. Dichlorobenzene yog cov kuab tshuaj tsis muaj xim thiab deodorizer siv nyob rau hauv mothballs thiab mildew tswj cov khoom.
Raws li koj tuaj yeem pom, cov txiaj ntsig ntawm cov lim dej ua kom muaj pa roj carbon monoxide tau dhau los ua qhov kev txhim kho saj. Qhov tshwj xeeb lim xov xwm no kuj txhim kho koj cov dej zoo.
Cov txiaj ntsig ntawm Activated Carbon Lim yog dab tsi?
Peb twb tau tham txog ntau yam txiaj ntsig ntawm activated carbon lim. Nov yog ob peb yam ntxiv vim li cas lawv thiaj nrhiav tau:
- Tsis muaj tshuaj lom neeg: Cov pa roj carbon activated siv adsorption es tsis txhob siv tshuaj los muab cov dej huv rau koj.
- Kev txhim kho saj: Tsis muaj leej twg xav kom lawv cov dej saj zoo li lub pas dej da dej lossis cov kav dej qub. Activated carbon dej lim tshem tawm cov khoom tsis zoo xws li chlorine, chloramines, sediment, hlau, thiab manganese.
- Ntau yam: Cov pa roj carbon activated tshem tawm ntau yam impurities los ntawm koj cov kais dej thiab ua haujlwm zoo nrog rau lwm cov xov xwm lim dej thiab cov thev naus laus zis.
- Pheej yig: Nws Nws yog qhov pheej yig dua kom tau txais tag nrho lub tsev lim uas siv cov pa roj carbon activated dua li rov qab osmosis.
