Technology
Cov series ntawm activated carbo yog tsim los ntawm cov thee.
The activated carbon txheej txheem yog ua tiav los ntawm kev siv ib qho kev sib xyaw ua ke ntawm cov kauj ruam hauv qab no:
1.) Carbonization: Cov khoom siv nrog cov ntsiab lus carbon yog pyrolyzed ntawm qhov kub ntawm 600-900 ℃, thaum tsis muaj oxygen (feem ntau nyob rau hauv inert cua nrog gases xws li argon los yog nitrogen).
2.) Ua kom muaj zog / Oxidation: Cov khoom siv raw lossis cov khoom siv carbonised raug oxidizing cua (carbon monoxide, oxygen, lossis chav dej) ntawm qhov kub siab tshaj 250 ℃, feem ntau nyob rau hauv qhov kub ntawm 600-1200 ℃.
