Cov yam ntxwv thiab cov khoom ntawm cov activated carbon sib txawv

Cov pa roj carbon activated yog cov khoom siv adsorption nrog zoo adsorption muaj peev xwm thiab tsis tu ncua. Qhov sib txawv tseem ceeb ntawm cov pa roj carbon activated sib txawv nyob hauv lawv cov khoom siv raw, kev npaj, thiab cov khoom adsorption.

1. Cov khoom siv sib txawv: Cov khoom siv raw ntawm cov khoom sib txawv ntawm cov tshuab txais carbon feem ntau yog ntoo, thee, asphalt, txiv maj phaub plhaub, chaff, txiv hmab txiv ntoo plhaub, thiab lwm yam. Muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg ntawm activated carbon npaj los ntawm cov khoom sib txawv.

2. Cov kev npaj sib txawv: Muaj ntau txoj hauv kev los npaj cov pa roj carbon activated sib txawv, suav nrog cov txheej txheem ntawm lub cev, cov txheej txheem tshuaj thiab cov txheej txheem physicochemical. Cov txheej txheem kev npaj sib txawv tuaj yeem cuam tshuam rau cov qauv pore thiab cov khoom saum npoo ntawm cov pa roj carbon activated.

3. Cov qauv pore sib txawv: Cov pa roj carbon activated sib txawv muaj qhov sib txawv ntawm qhov pore qauv qhov ntau thiab tsawg, cov duab, thiab qhov pore faib ntom ntom, suav nrog micropores, mesopores, thiab macropores. Cov qauv pore sib txawv muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm adsorption ntawm cov pa roj carbon activated.

4. Cov khoom sib txawv adsorption: Cov pa roj carbon activated sib txawv muaj cov khoom sib txawv adsorption rau cov khoom sib txawv. Piv txwv li, qee cov pa roj carbon activated muaj peev xwm adsorption zoo dua rau cov khoom siv hauv cov pa roj, thaum lwm tus muaj cov nyhuv adsorption zoo dua rau cov hlau hnyav ions hauv cov tshuaj aqueous.

Zuag qhia tag nrho, sib txawv activated carbons ua txawv thiab muaj ntau yam kev siv. Nyob rau hauv daim ntawv thov, nws yog ib qhov tsim nyog los xaiv qhov tsim nyog activated carbon raws li cov kev xav tau tshwj xeeb.

Cov pa roj carbon activated yog cov khoom siv adsorption zoo heev. Raws li lub hauv paus, txoj kev kho mob thiab kev siv cov pa roj carbon activated, nws cov yam ntxwv thiab cov khoom kuj txawv, feem ntau suav nrog cov ntsiab lus hauv qab no:

1. Cov porosity siab: Lub porosity ntawm cov pa roj carbon activated feem ntau yog siab heev, uas tuaj yeem ncav cuag ntau dua 1000m³ / g. Cov qauv ntxeem tau no yog ib qho ntawm cov laj thawj tseem ceeb rau nws qhov kev ua tau zoo adsorption.

2. Muaj zog adsorption: Cov pa roj carbon activated muaj qhov loj heev thiab qhov pore sib txawv, yog li nws tuaj yeem nqus tau ntau yam organic tshuaj, gases thiab impurities hauv cov kua dej. Qhov no muaj zog adsorption kuj yog ib qho tseem ceeb vim li cas activated carbon yog dav siv.

3. Kev ruaj ntseg tshuaj zoo: Cov pa roj carbon activated muaj cov tshuaj lom neeg zoo, feem ntau tsis yooj yim rau decompose, insoluble hauv dej thiab ntau cov kuab tshuaj organic, thiab yuav tsis degrade vim ya raws los yog tawg, thiab tuaj yeem siv rau hauv ib puag ncig sib txawv.

4. Kev lag luam: Cov pa roj carbon activated yog tus nqi qis, cov khoom siv tau yooj yim thiab yog li ib qho ntawm cov ntaub ntawv xaiv hauv ntau daim ntawv thov kev lag luam.

5. Cov yam ntxwv ntawm qhov sib txawv: Vim muaj qhov sib txawv ntawm cov pa roj carbon activated, nws lub cev thiab tshuaj lom neeg kuj sib txawv. Piv txwv li, wood-based activated carbon muaj qhov chaw me me thiab qhov pore loj, thiab yog tsim rau decolorization, deodorization, thiab kev kho dej ntshiab; thaum cov pa roj carbon monoxide muaj qhov chaw siab thiab qhov porosity, thiab yog tsim rau cov pa roj adsorption, catalyst carriers, thiab lwm yam teb; mixed activated carbons yog tsim los ntawm Kev Npaj los ntawm kev sib tov ntau yam khoom siv raw, nws muaj qhov zoo ntawm qhov dav adsorption ntau thiab kev kho kom zoo, thiab yog siv dav hauv kev kho dej, kev kho roj khib nyiab, kev kho dej hauv tsev thiab lwm yam haujlwm.

Feem ntau hais lus, activated carbon muaj ntau yam khoom xws li adsorption, sib cais, thiab purification. Nws cov khoom thiab cov yam ntxwv sib txawv vim yog yam xws li qhov chaw, kev siv thev naus laus zis, qhov pore loj faib, thiab lwm yam, yog li nws yuav tsum xaiv cov pa roj carbon activated tsim nyog raws li cov kev xav tau tshwj xeeb.
