Qhov sib txawv tseem ceeb ntawm acetylene dub thiab carbon dub yog acetylene dub yog tau los ntawm thermal decomposition ntawm acetylene, whereas carbon dub yog tsim los ntawm tsis tiav combustion ntawm hnyav roj av compounds.
Carbon dub yog ib qho tseem ceeb adsorbing tus neeg sawv cev. Acetylene dub yog ib hom carbon dub uas txawv ntawm lwm hom carbon dub khoom nyob ntawm qhov chaw tsim khoom.
Acetylene Dub yog dab tsi?
Acetylene dub yog hom carbon dub. Nws yog tau los ntawm acetylene thermal decomposition txheej txheem. Hom carbon dub no yog purified heev, thiab nws kuj yog ib yam khoom uas tsis tshua muaj conductive. Yog li ntawd, nws yog ib qho tseem ceeb heev rau kev tsim cov hlwb qhuav, hluav taws xob cables, cov khoom siv silicon, thiab lwm yam. Peb tuaj yeem siv acetylene dub los hloov cov roj carbon dub.
Carbon Black yog dab tsi?
Carbon dub yog ib qho inorganic compound uas tsim los ntawm kev ua tsis tiav ntawm cov khoom siv roj av hnyav. Nws yog ib qho adsorbing tus neeg sawv cev. Muaj ob peb subtypes ntawm carbon dub xws li acetylene dub, channel dub, rauv dub, teeb dub, thiab thermal dub. Cov khoom siv roj av hnyav yog qhov muaj txiaj ntsig zoo rau kev tsim cov khoom siv no. Piv txwv li, FCC tar, thee tar, ethylene cracking tar, thiab lwm yam. Txawm li cas los xij, cov khoom no yuav tsum tsis txhob tsis meej pem nrog soot.
Daim duab 01: Qhov tshwm sim ntawm Carbon Black
Carbon dub tsuas muaj cov pa roj carbon atoms xwb, thiab cov khoom no zoo nkaus li cov hmoov dub. Xyaum, cov hmoov no tsis yaj hauv dej. Txij li thaum tsuas muaj cov pa roj carbon atoms nyob rau hauv cov compound no, molar mass ntawm carbon dub yog 12 g / mol. Txhua hom carbon dub muaj chemisorbed oxygen complexes. E.g. carboxylic, quinonic, lactonic, thiab lwm yam. Peb tuaj yeem soj ntsuam cov complexes ntawm cov pa roj carbon dub. Raws li cov tshuaj tiv thaiv kab mob thiab cov txheej txheem tsim khoom, cov qib ntawm cov complexes ntawm particle nto txawv. Cov complexes saum npoo no feem ntau 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 haum.
Muaj ntau yam kev siv tseem ceeb ntawm carbon dub. Piv txwv li, nws yog ib qho tseem ceeb raws li cov khoom siv txhawb zog. Nws yog ib qho tseem ceeb ua ib qho kev txhawb nqa rau cov log tsheb thiab lwm yam khoom siv roj hmab. Ntxiv rau qhov ntawd, nws yog ib qho tseem ceeb raws li cov xim xim hauv cov xim, yas, number case, thiab lwm yam. Cov pa roj carbon dub uas muaj cov zaub hauv paus yog siv los ua cov xim zaub mov.
Qhov txawv ntawm Acetylene Dub thiab Carbon Dub yog dab tsi?
Carbon dub yog ib qho tseem ceeb adsorbing tus neeg sawv cev. Acetylene dub yog ib hom carbon dub uas txawv ntawm lwm hom carbon dub cov khoom nyob ntawm qhov chaw tsim khoom. Raws li nws lub npe qhia, lub hauv paus ntawm acetylene dub yog acetylene thaum lub hauv paus ntawm carbon dub yog hnyav roj av khoom. Yog li ntawd, qhov sib txawv tseem ceeb ntawm acetylene dub thiab carbon dub yog acetylene dub yog tau los ntawm thermal decomposition ntawm acetylene whereas carbon dub yog tsim los ntawm tsis tiav combustion ntawm cov roj av hnyav. Txawm li cas los xij, peb tuaj yeem siv acetylene dub los hloov cov pa roj carbon dub.
Hauv qab infographic qhia txog qhov sib txawv ntawm acetylene dub thiab carbon dub.
Summary – Acetylene Black vs Carbon Black
Carbon dub yog ib qho tseem ceeb adsorbing tus neeg sawv cev. Acetylene dub yog ib hom carbon dub uas txawv ntawm lwm hom carbon dub cov khoom nyob ntawm qhov chaw tsim khoom. Qhov sib txawv tseem ceeb ntawm acetylene dub thiab carbon dub yog tias acetylene dub yog tau los ntawm thermal decomposition ntawm acetylene whereas carbon dub yog tsim los ntawm tsis tiav combustion ntawm hnyav roj av tebchaw.
