Coal activated carbon yog dab tsi?

Cov pa roj carbon activated tau tsim cov qauv pore, kev ua haujlwm zoo adsorption, muaj zog txhua yam, yooj yim rau rov tsim dua tshiab, tus nqi qis thiab lwm yam ntxwv; Nws yog siv rau purification ntawm cov pa roj, pov tseg roj kho, purification ntawm industrial thiab domestic dej, hnyav rov qab thiab lwm yam.
Khoom Taw Qhia
Coal-based activated carbon siv cov thee zoo li cov khoom siv raw, thiab tsim los ntawm cov txheej txheem xws li carbonization → txias → ua kom → ntxuav. Nws cov tsos yog feem ntau dub cylindrical activated carbon, amorphous thee-based granular activated carbon, tseem hu ua cov pa roj carbon tawg. Cylindrical activated carbon tseem hu ua columnar carbon, uas feem ntau yog ua los ntawm hmoov raw cov ntaub ntawv thiab binders los ntawm kev sib tov, extrusion molding, thiab ces carbonization, ua kom thiab lwm yam txheej txheem. Powdered activated carbon plus binder kuj tuaj yeem raug extruded.
