Activated Carbon vs Charcoal
Carbon nyob txhua qhov chaw. Muaj ntau lab lub tebchaw, uas yog tsim los ntawm carbon. Peb tuaj yeem hais tias, carbon yog lub hauv paus rau peb lub cev, cov nroj tsuag thiab microorganisms. Tsis tas li ntawd, lawv muaj nyob rau hauv xwm, nyob rau hauv ntau hom, xws li graphite, pob zeb diamond, charcoal thiab lwm yam.
Charcoal
Charcoal muaj cov ntsiab lus carbon. Carbonic tebchaw muaj ntau nyob rau hauv cov nroj tsuag, tsiaj txhu thiab lwm yam kab mob nyob. Yog li ntawd, thaum lawv tuag, cov carbonic compounds yog thaum kawg hloov mus rau lwm cov carbonic compounds. Charcoal yog ib qho ntawm cov khoom no. Thaum dej thiab lwm yam khoom tsis hloov pauv tau raug tshem tawm los ntawm cov khoom sib txuas carbonic, cov khoom tsim tawm yog charcoal. Charcoal yog nyob rau hauv daim ntawv, thiab nws muaj ib tug tsaus grey xim. Nws muaj tshauv; Yog li ntawd, charcoal tsis muaj carbon nyob rau hauv nws daim ntawv ntshiab. Charcoal yog tsim los ntawm pyrolysis. Qhov no yog ib txoj hauv kev, qhov twg cov ntaub ntawv organic yog decomposed ntawm qhov kub thiab txias thaum tsis muaj oxygen. Yog li ntawd, cov tshuaj muaj pes tsawg leeg thiab lub cev theem ntawm cov teeb meem yuav hloov sai heev. Piv txwv li, los ntawm cua sov ntoo peb tuaj yeem tau charcoal. Muaj ob peb hom charcoal. Lawv muaj raws li nram no.
• pob charcoal
• Extruded charcoal
• Japanese charcoal
• Briquettes
Cov charcoal ua cov hmoov tshauv tsawg, thiab nws yog tsim los ntawm cov khoom siv ntoo. Extruded charcoal yog tsim los ntawm cov cav ntoo, uas tau raug extruded los ntawm cov ntoo hauv av los yog cov ntoo carbonized. Briquettes yog tsim los ntawm cov saw plua plav thiab lwm yam ntoo los ntawm cov khoom siv los ntawm kev sib khi. Japanese charcoal tsis muaj pyroigneous acid vim tias nws raug tshem tawm hauv cov txheej txheem charcoal. Hom charcoal no tsis tsim cov ntxhiab tsw lossis pa taws thaum hlawv. Muaj peb hom Japanese charcoal li dawb charcoal, Ogatan thiab dub charcoal. Muaj ntau yam kev siv rau charcoal. Nws muaj keeb kwm ntev; txij thaum ntxov tshaj plaws, charcoal tau siv los ua roj. Txawm niaj hnub no nws yog siv los ua roj tseem ceeb hauv tsev thiab kev lag luam. Charcoal tuaj yeem tsim hluav taws xob kub vim tias cov hluav taws kub kub kub. Charcoal kuj ntxiv rau hauv av kom txhim kho cov av zoo. Hauv tshuaj, charcoal yog siv los kho mob plab. Txawm hais tias muaj ntau yam kev siv, kev tsim hluav taws xob muaj kev cuam tshuam tsis zoo rau ib puag ncig. Qhov no yog ib qho kev hem thawj rau hav zoov vim tus nqi ntawm deforestation nce siab nyob rau hauv cov cheeb tsam uas tsim charcoal.
Activated carbon
Activated carbon tseem hu ua activated charcoal. Thaum tsim cov pa roj carbon activated, charcoal yog kho nrog oxygen. Thaum charcoal qhib, nws yog ua tiav nyob rau hauv ib txoj kev los ua kom cov porosity. Vim li no, cov pa roj carbon activated yuav muaj thaj chaw loj, uas tuaj yeem nqus cov khoom zoo. Qhov no feem ntau nce nws cov txiaj ntsig zoo li cov lim dej. Yog li, cov pa roj carbon activated feem ntau yog siv hauv cov lim dej, hauv cov txheej txheem tshuaj purification, thiab tshuaj. Thaum peb siv lawv, cov impurities zoo li sib sau ua ke hauv cov pa roj carbon monoxide. Yog li qhov tsis zoo ntawm kev siv qhov no yog qhov lawv ua tsis tau zoo thaum peb siv lawv.
Qhov txawv ntawm Activated Carbon thiab Charcoal yog dab tsi?
• activated carbon yog tsim los ntawm charcoal.
• Charcoal yog tsim thaum tsis muaj oxygen. Txhawm rau tsim cov pa roj carbon activated, charcoal yog kho nrog oxygen.
• Cov pa roj carbon activated muaj txiaj ntsig ntau dua li cov lim dej, qhov charcoal tseem ceeb dua li roj.
