Qhov sib txawv tseem ceeb ntawm cov pa roj carbon dub thiab cov pa roj carbon activated yog qhov sib piv ntawm thaj chaw-rau-ntim ntawm cov pa roj carbon dub yog qis dua li cov pa roj carbon activated.
Ob leeg cov pa roj carbon dub thiab cov pa roj carbon activated yog cov ntaub ntawv tseem ceeb ua cov tshuaj adsorbing. Lawv muaj thaj chaw siab siab piv rau lawv qhov ntim, uas tso cai rau cov khoom nqus tau ntau npaum li nws tuaj yeem ua tau. Peb hu lawv paracrystalline carbon compounds.
Carbon Black yog dab tsi?
Carbon dub yog ib qho adsorbing tus neeg sawv cev uas tsim los ntawm kev ua tsis tiav ntawm cov khoom siv roj av hnyav. Muaj ob peb subtypes ntawm carbon dub, nrog rau acetylene dub, channel dub, rauv dub, teeb dub, thiab thermal dub. Cov khoom siv roj av hnyav uas tuaj yeem siv los ua qhov chaw tsim cov pa roj carbon dub yog FCC tar, thee tar, ethylene cracking tar, thiab lwm yam. Txawm li cas los xij, cov khoom siv no yuav tsum tsis txhob tsis meej pem nrog soot.
Daim duab 01: Carbon Dub
Carbon dub tsuas muaj cov pa roj carbon atom xwb. Nws tshwm raws li cov hmoov dub. Xyaum, cov hmoov no yog insoluble hauv dej. Cov molar loj ntawm carbon dub yog 12 g / mol. Txhua hom carbon dub muaj chemisorbed oxygen complexes. E.g. carboxylic, quinonic, lactonic, thiab lwm yam. Cov complexes yog nyob rau saum npoo ntawm carbon dub hais. Nyob ntawm cov xwm txheej thiab cov txheej txheem tsim khoom, cov qib ntawm cov complexes ntawm particle nto txawv. Cov tebchaw saum npoo no suav hais tias yog hom tsis hloov pauv. Tsis tas li ntawd, cov pa roj carbon dub yog cov khoom siv tsis zoo vim nws cov ntsiab lus tsis hloov pauv.
Ntxiv mus, muaj ntau daim ntawv thov ntawm carbon dub. Nws yog ib qho tseem ceeb ntawm cov khoom siv ntxiv dag zog. Nws yog siv los ua cov khoom siv ntxiv rau cov log tsheb thiab lwm yam khoom siv roj hmab. Tsis tas li ntawd, nws yog siv los ua cov xim xim hauv cov xim, yas, number case, thiab lwm yam. Cov pa roj carbon dub uas muaj cov zaub hauv paus muaj txiaj ntsig zoo li cov xim zaub mov.
Dab tsi yog Activated Carbon?
Activated carbon yog ib qho adsorbing tus neeg sawv cev uas tau muab los ntawm charcoal. Yog li ntawd, nws tseem hu ua activated los yog active charcoal. Cov khoom no yog ua los ntawm cov pa roj carbon atoms thiab nws muaj qhov siab heev ntawm qhov chaw-rau-ntim piv. Nws muaj cov pores tsawg uas ua rau thaj tsam ntawm cov khoom, tso cai rau nws adsorb cov ntaub ntawv ntau npaum li nws ua tau.
Daim duab 02: Ua kom cov pa roj carbon monoxide
Muaj ntau siv cov pa roj carbon activated. Nws yog ib qho tseem ceeb hauv methane thiab hydrogen gas cia, huab cua purification vim nws muaj peev xwm adsorption, hnyav rov qab, decaffeination, kub purification, hlau extraction, kho tshuaj lom thiab overdose tej yam kev mob, nyob twj ywm theem rau chromatographic sib cais cov tswv yim, thiab lwm yam.
Qhov txawv ntawm Carbon Dub thiab Activated Carbon yog dab tsi?
Qhov sib txawv tseem ceeb ntawm cov pa roj carbon dub thiab cov pa roj carbon activated yog qhov sib piv ntawm thaj chaw-rau-ntim ntawm cov pa roj carbon dub yog qis dua li cov pa roj carbon activated. Peb hu lawv paracrystalline carbon compounds. Tsis tas li ntawd, carbon dub yog tsim los ntawm kev ua tsis tiav ntawm cov khoom siv roj av hnyav thaum cov pa roj carbon activated yog tsim los ntawm charcoal.
Hauv qab infographic qhia txog qhov sib txawv ntawm cov pa roj carbon dub thiab cov pa roj carbon activated.
Summary – Carbon Black vs Activated Carbon
Ob leeg cov pa roj carbon dub thiab cov pa roj carbon activated yog ib qho tseem ceeb ua cov tshuaj adsorbing. Qhov sib txawv tseem ceeb ntawm cov pa roj carbon dub thiab cov pa roj carbon activated yog qhov sib piv ntawm thaj chaw-rau-ntim ntawm cov pa roj carbon dub yog qis dua li cov pa roj carbon activated. Peb hu lawv ua paracrystalline carbon compounds.
