Nyob rau hauv lub kaum sab xis pom, kev tiv thaiv ntawm purity yog nyob ntsiag to. Tsis muaj suab nrov, tseem nyob txhua qhov chaw - qhov no yog lub luag haujlwm ntawm kev lim dej. Raws li kev ua haujlwm ntawm tsev neeg cov pa roj carbon activated, lim cov pa roj carbon monoxide tau dhau los ua ib feem tseem ceeb ntawm kev lim dej, kev kho cua, thiab kev tiv thaiv ib puag ncig vim nws cov qauv pore meej thiab lub cev muaj zog adsorption muaj peev xwm. Nws tsis yog ostentatious, tab sis nws txhais lub zog ntawm "moistening yam ntsiag to" nrog nws lub zog.
Filtering charcoal tsis yog cov pa roj carbon zoo tib yam, tab sis muaj kev ua haujlwm siab - cov khoom adsorbent refined los ntawm cov txheej txheem xws li siab - kub ua kom kub thiab kev hloov kho. Nws cov micropores sab hauv yog ntom, nrog rau thaj chaw tshwj xeeb ntawm ntau txhiab square metres ib gram, zoo li suav tsis txheeb cov "cov hlau nplaum", raug ntes cov pa phem hauv dej thiab huab cua. Txawm hais tias nws yog cov tshuaj chlorine uas nyob hauv cov kais dej, formaldehyde thiab benzene gases tso tawm los ntawm kev kho kom zoo nkauj hauv tsev tshiab, lossis cov organic volatile compounds hauv kev lag luam emissions, lim carbon tuaj yeem cuam tshuam lawv, tsim thawj kab ntawm kev tiv thaiv rau ib puag ncig noj qab haus huv.
Hauv kev teeb tsa hauv tsev, lim charcoal yog siv dav hauv cov dej purifiers, central water purification systems, and air purifiers. Nws tsis tsuas yog txhim kho cov saj ntawm cov dej haus, tab sis kuj txo qhov kev noj cov tshuaj phem. Nyob rau hauv kev lag luam sector, lim charcoal lub luag hauj lwm tseem ceeb tshaj: kev lag luam xws li tshuaj, khoom noj khoom haus, thiab chemicals cia siab rau lim carbon rau decolorization, purification, thiab tso pa roj kev kho mob los xyuas kom meej cov khoom muaj kev ruaj ntseg thiab emission qauv. Cov ntaub ntawv sib txawv ntawm cov pa roj carbon lim dej yog tsim rau cov khoom siv sib txawv kom ua tau zoo, tsis muaj zog, thiab ua haujlwm ntev - lub neej ua haujlwm.
Dab tsi yog qhov qhuas tshaj yog tias lim charcoal muaj cov yam ntxwv txuas ntxiv mus. Tom qab siab - qhov kub thiab txias los yog hluav taws xob cua sov kho dua tshiab, nws lub peev xwm adsorption tuaj yeem rov qab mus rau ntau dua 80%, txo cov nqi siv thiab cov peev txheej pov tseg, raws li lub tswv yim ntawm kev lag luam ntsuab.
Los ntawm qhov pom tseeb ntawm cov dej ntws mus rau qhov tshiab ntawm kev ua pa ntawm huab cua, lim charcoal tiv thaiv kab hauv qab ntawm lub neej niaj hnub nrog kev ntsiag to tsis tau ruaj khov. Nws tsis yog tus protagonist nyob rau hauv lub tsom teeb, tab sis kev txhawb siab tshaj plaws tom qab lub ntiaj teb huv si.
