Kev taw qhia thiab kev faib tawm ntawm cov pa roj carbon activated

Cov pa roj carbon activated, tseem hu ua activated charcoal, yog cov khoom siv ntuj tsim los yog hluavtaws uas tau dhau los ua cov txheej txheem los ua kom nws qhov chaw ntog thiab porosity, tso cai rau nws kom nqus tau zoo thiab lim ntau yam impurities thiab tshuaj. Cov pa roj carbon activated yog siv rau ntau yam kev siv, suav nrog dej thiab huab cua purification, deodorization, thiab ua ib qho adsorbent hauv ntau cov txheej txheem kev lag luam.

Cov pa roj carbon activated tuaj yeem muab faib ua ntau hom raws li lawv qhov chaw, khoom, thiab txheej txheem tsim khoom. Feem ntau hom activated carbon muaj xws li:

1. Coal-Based Activated Carbon: Coal-based activated carbon yog tsim los ntawm cov thee los ntawm cov cua sov ntawm qhov kub thiab txias thaum tsis muaj oxygen. Nws muaj qhov chaw siab tshaj plaws thiab muaj peev xwm adsorption siab, ua rau nws zoo tagnrho rau kev siv xws li kev kho dej, hnyav rov qab, thiab huab cua purification.

2. Txiv maj phaub Plhaub-Based Activated Carbon: Txiv maj phaub plhaub-raws li tshuab txais carbon yog tsim los ntawm txiv maj phaub plhaub, uas yog rhuab nyob rau hauv high kub nyob rau hauv lub xub ntiag ntawm chav. Nws muaj microporosity siab thiab yog siv rau cov ntawv thov xws li huab cua purification, dej kho, thiab roj theem adsorption.

3. Wood-Based Activated Carbon: Ntoo-raws li activated carbon yog tsim los ntawm cua sov ntoo ntawm qhov kub thiab txias nyob rau hauv lub xub ntiag ntawm ib tug activating neeg sawv cev. Nws muaj peev xwm adsorption siab thiab siv rau hauv daim ntawv thov xws li roj theem adsorption, decolorization, thiab qab zib refining.

4. Lignite-Based Activated Carbon: Lignite-based activated carbon yog tsim los ntawm lignite thee los ntawm carbonization thiab activation. Nws muaj cov nqi tsim khoom tsawg thiab feem ntau yog siv rau kev kho dej thiab decolorization.

Hauv kev xaus, activated carbon yog ntau yam khoom siv uas muaj ntau yam kev siv hauv ntau yam lag luam. Nws yog ib qho khoom siv tseem ceeb hauv cov txheej txheem ntawm kev ntxuav lossis ntxuav cov kua thiab roj los ntawm kev tshem tawm cov impurities, cov pa phem thiab cov pa phem. Paub txog ntau yam ntawm cov pa roj carbon activated tuaj yeem coj koj xaiv cov khoom siv zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb.
