Porous adsorbent katundu!

Porous material adsorbent ndi chinthu cholimba chomwe chimatha kutulutsa bwino zinthu zina kuchokera ku gasi kapena madzi, zomwe zimakhala ndi malo akuluakulu enieni, mawonekedwe a pore oyenera komanso mawonekedwe apamwamba, komanso mphamvu zogwiritsira ntchito adsorbates. , kuzipangitsa kukhala zosavuta kupanga komanso zosavuta kuzipanganso. Iwo ali kwambiri adsorption ndi makina katundu.

Kuthekera kwa ma adsorbent makamaka kumachokera ku porosity yake komanso kuchuluka kwa malo omwe amatsatsa omwe amapangidwa ndi malo ake apamwamba kwambiri. Pamene malo onse omwe akugwira ntchito mu adsorbent ali otanganidwa, mphamvu yake ya adsorption imafika pa machulukitsidwe. Ngati adsorbate ikugwira malo omwe akugwira ntchito, njirayi imasinthidwa ndikutchedwa adsorbent saturation. Zimafunikira kutentha, kupsinjika maganizo, ndi njira zina zotsitsimutsa kuti abwezeretse ntchito ya adsorption ya adsorbent yodzaza kale; Ngati chinthu chomwe chikukhala pamalo otsatsa sichinthu chotsatsa, koma zinthu zina zomwe zimakhala zovuta kuzichotsa pamalopo, ma adsorption ndi osasinthika ndipo adsorbent sangathe kugwiritsidwanso ntchito. Chodabwitsa ichi chimatchedwa adsorbent poisoning.

Kuthekera kwa adsorbents kumakhala ndi malire apamwamba, ndipo ma adsorbents osiyanasiyana ali ndi kulolerana kwamadzi kosiyana. Mwachitsanzo, calcium chloride desiccants imatha kuyamwa chinyezi kuchokera ku chilengedwe ndikusungunula pang'onopang'ono pansi pa chinyezi chachibadwa, koma kulowa m'madzi mwachindunji kumangosungunuka mwachindunji ndipo sikungathe "kulanda" chinyezi; Gelisi wamba wa silikoni amakhala ndi zotsatira zabwino pakutulutsa chinyezi m'malo achinyezi, koma kuviika m'madzi kungayambitse kuyamwa kwamadzi mopitilira muyeso komanso mwachangu, zomwe zimapangitsa kusweka; 5Sieve ya molekyulu imatha kulekanitsa nayitrogeni ndi nthunzi wamadzi mumlengalenga, koma imakhala ndi mphamvu yamphamvu kwambiri yolumikizira madzi. M'malo achinyezi kwambiri, imatenga madzi mwachangu ndikudzaza, zomwe zimakhudza kwambiri kulekanitsa kwake kwazinthu zina.
