Tsawg tshauv thee activated carbon yog ib hom activated carbon uas yog tsim los ntawm tsawg tshauv thee. Cov pa roj carbon activated yog cov khoom ntxeem tau uas feem ntau siv los tshem cov impurities ntawm cov pa roj thiab cov kua dej, xws li dej thiab cua.
Cov hmoov tshauv tsawg yog ib hom thee uas muaj cov hmoov tshauv tsawg. Tshauv yog cov inorganic residue uas tshuav tom qab cov thee hlawv. Cov hmoov tshauv qis yog qhov tsim nyog rau kev tsim cov pa roj carbon activated vim tias nws tsim cov pa roj carbon nrog cov qib siab purity thiab qib qis ntawm impurities.
Tsawg tshauv thee activated carbon feem ntau yog siv nyob rau hauv ntau yam kev siv, nrog rau kev kho dej, huab cua purification, thiab gas sib cais. Nws qhov chaw siab tshaj plaws thiab cov qauv ntxeem tau ua rau nws muaj txiaj ntsig zoo rau ntau yam kab mob, xws li cov organic sib txuas, cov hlau hnyav, thiab chlorine.
Kev tsim cov hmoov tshauv qis qis ua kom cov pa roj carbon feem ntau cuam tshuam nrog cov txheej txheem ntawm carbonization, ua kom, thiab purification. Thaum lub sij hawm carbonization, cov thee yog rhuab nyob rau hauv qhov tsis muaj huab cua los hloov nws mus rau hauv cov khoom uas nplua nuj carbon. Tom qab ntawd cov pa roj carbon activated yog tsim los ntawm kev ua kom cov pa roj carbonized nrog cov pa roj lossis tshuaj lom neeg, uas tsim cov qauv ntxeem tau. Thaum kawg, cov activated carbon yog purified kom tshem tawm tej impurities seem.
Cov pa roj carbon activated yog ib daim ntawv uas muaj cov pa roj carbon ntau, uas yog tsim los ntawm kev kho ntau yam ntaub ntawv carbonaceous xws li thee, txiv maj phaub plhaub, ntoo, thiab peat nrog chav lossis tshuaj.
Coal activated carbon yog tsim los ntawm kev xa cov thee mus rau cov txheej txheem kub kub hu ua activation. Thaum lub sijhawm txheej txheem no, cov thee tau rhaub hauv qhov muaj cov pa oxidizing, xws li cua lossis chav, los tsim cov pores me me hauv cov khoom. Cov pores no ua rau thaj tsam ntawm cov thee, tso cai rau nws mus rau adsorb ntau yam ntawm impurities thiab cov kab mob.
Nyob rau hauv cov ntsiab lus, thee activated carbon yog ib tug ntxeem tau carbon cov ntaub ntawv uas ua los ntawm cov thee rau high-temperature activation, uas ho nce nws nto thiab adsorption muaj peev xwm.
