Cov khoom ntxeem tau adsorbent yog cov khoom siv uas muaj peev xwm ua tau zoo adsorb qee yam ntawm cov roj los yog kua, uas muaj cov cheeb tsam loj, tsim cov pore thiab cov qauv saum npoo, thiab muaj peev xwm adsorption muaj zog rau adsorbates.Adsorbents feem ntau tsis muaj tshuaj lom neeg nrog adsorbates thiab nruab nrab. , ua rau lawv yooj yim los tsim thiab yooj yim rau regenerate.Lawv muaj zoo heev adsorption thiab mechanical zog.
Lub peev xwm adsorption ntawm ib qho adsorbent feem ntau yog los ntawm nws qhov porosity thiab ntau qhov chaw ua haujlwm adsorption tsim los ntawm nws qhov chaw siab tshwj xeeb.Thaum tag nrho cov chaw nquag hauv cov adsorbent tau nyob, nws lub peev xwm adsorption ncav cuag saturation.Yog tias cov adsorbate nyob hauv qhov chaw nquag, cov txheej txheem no thim rov qab thiab hu ua adsorbent saturation.Nws yuav tsum tau cua sov, depressurization, thiab lwm txoj hauv kev tsim kho kom rov qab ua haujlwm adsorption ntawm cov adsorbent uas twb muaj lawm;Yog tias cov khoom siv nyob hauv qhov chaw adsorption tsis yog adsorbate, tab sis lwm yam khoom uas nyuaj rau tshem tawm ntawm qhov chaw adsorption, qhov adsorption yog irreversible thiab cov adsorbent siv tsis tau dua.Qhov tshwm sim no hu ua adsorbent lom.
Lub peev xwm adsorption ntawm adsorbents muaj qhov txwv siab, thiab cov adsorbents sib txawv muaj qhov sib txawv ntawm cov dej.Piv txwv li, calcium chloride desiccants tuaj yeem nqus dej noo los ntawm ib puag ncig thiab maj mam yaj nyob rau hauv cov av ib txwm muaj, tab sis soaking ncaj qha rau hauv dej tsuas yog yaj ncaj qha thiab tsis tuaj yeem "ntub" cov dej noo;Ordinary silicone gel muaj cov nyhuv zoo hauv adsorbing noo noo nyob rau hauv high humidity ib puag ncig, tab sis soaking nyob rau hauv dej yuav ua rau kom cov dej ntau dhau thiab sai sai, ua rau tawg;5A molecular sieve tuaj yeem cais cov nitrogen thiab dej vapor hauv huab cua, tab sis nws muaj peev xwm adsorption muaj zog tshwj xeeb rau cov dej.Nyob rau hauv high humidity ib puag ncig, nws sai absorbs dej thiab saturates, heev cuam tshuam rau kev sib cais efficiency ntawm nws rau lwm yam khoom.
