Kev ntsuas dej adsorption
Dej adsorption tuaj yeem muab faib ua dej zoo li qub adsorption thiab dynamic dej adsorption.Static dej adsorption,txhais tau tias nyob rau hauv cov mob ntawm ib tug tej yam kub thiab humidity ib puag ncig, Tom qab ncav cuag dynamic equilibrium, lub adsorbed dej cov ntsiab lus ntawm cov adsorbent, uas nyob rau hauv lub tshuab kev ua tau zoo yog cov ntaub ntawv ntawm kev ua hauj lwm tas li,cov ntaub ntawv dej zoo li qub adsorption ntau dua,lub dew point ntawm lub export gas kev ua tau zoo yuav zoo dua.
Dynamic water adsorption yog hais txog tus nqi adsorption ntawm adsorbent adsorbed dej nyob rau hauv airflow mus rau lub txaj nkag, uas yog, thaum adsorbing dej nyob rau hauv lub airflow, qhov hnyav ntxiv tom qab ncav cuag lub dew point.Vim yog qhov sib txawv ntawm kev ua haujlwm thiab cov qauv, cov dej lwg taw tes yogkuj txawv.Tab sis tib yam li cov dej zoo li qub adsorption,ob leegof dej adsorption yog siab dua, qhov zoo dua qhov adsorption kev ua tau zoo ntawm cov khoom.
Kev tsom xam ntawm thaj chaw saum npoo
Qhov chaw saum npoo ntawm ib chav tsev loj ntawm cov khoom, uas cuam tshuam nrog kev ua haujlwm adsorption.Qhov loj dua qhov chaw tshwj xeeb, qhov loj dua qhov theoretical contact nto nrog airflow, kom lub adsorption ceev nrawm dua thiab cov adsorption muaj zog dua.
In tusdaim ntawv thovntawm lub tshuab ziab khaub ncaws, qhov saum npoocheeb tsamntawm cov adsorbentntau dua,, qhov loj dua qhov kev sib cuag nrog cov airflow thiab qis dua cov dej lwg.Feem ntau hais lus, rau txhua txhua 100m2 / g nce hauv thaj chaw tshwj xeeb, tus nqi adsorption nce 5-10% hauv RH60% ib puag ncig txheeb ze.
Pore volume tsom xam
Yog tias koj saib nyob rau hauv lub tshuab tsom, koj yuav pom tias cov alumina activated muaj ntau qhov micro-pores, uas yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov khoom ntxeem tau adsorbent lossis catalyst.Lub ntim ntawm micro-pore nyob rau hauv lub adsorbent yog hu ua pore muaj peev xwm, uas yog tus nqi muab tau los ntawm lub saturation adsorption ntim, uas yog, npaum li cas ntim ntawm adsorbent yuav tuav lub adsorbent, yog li qhov loj pore muaj peev xwm, qhov zoo dua.Lub pore ntim yuav tsum tau rau activated alumina yog ntau dua los yog sib npaug rau 0. 35 cm³ / g nyob rau hauv tus qauv kab.
