Izakhiwo ze-adsorbent ezinezimbotshana!

I-Porous material adsorbent iyinto eqinile engakhanga ngokuphumelelayo izingxenye ezithile zegesi noma uketshezi, ezinendawo enkulu ethize engaphezulu, ukwakheka kwezimbotshana ezifanele kanye nesakhiwo esingaphezulu, kanye nomthamo oqinile wokukhangisa wama-adsorbates. , okwenza kube lula ukuwenza futhi kube lula ukuwenza kabusha. Banezakhiwo ezinhle kakhulu ze-adsorption kanye nemishini.

Umthamo we-adsorption we-adsorbent uvela ikakhulukazi ekuqineni kwayo kanye nenani elikhulu lamasayithi okukhangisa akhiqizwa indawo yayo ephezulu ethile. Uma wonke amasayithi asebenzayo ku-adsorbent esetshenziswa, umthamo wayo we-adsorption ufinyelela ekugcwalisweni. Uma i-adsorbate ithatha amasayithi asebenzayo, le nqubo iyabuyiselwa emuva futhi ibizwa ngokuthi i-adsorbent saturation. Kudinga ukushisisa, ukucindezelwa, nezinye izindlela zokukhiqiza kabusha ukuze ubuyisele ukusebenza kwe-adsorption ye-adsorbent esivele igcwele; Uma into ehlezi endaweni ye-adsorption ingeyona i-adsorbate, kodwa ezinye izinto okunzima ukuzikhipha endaweni ye-adsorption, i-adsorption ayikwazi ukuhlehliswa futhi i-adsorbent ayikwazi ukusetshenziswa futhi. Lesi simo sibizwa nge-adsorbent poisoning.

Umthamo we-adsorption we-adsorbents unomkhawulo ophezulu, futhi ama-adsorbents ahlukene anokubekezela okuhlukile kwamanzi. Isibonelo, ama-desiccants e-calcium chloride angakwazi ukumunca umswakama emvelweni futhi ancibilike kancane kancane ngaphansi kwezimo ezivamile zomswakama, kodwa ukucwilisa ngokuqondile emanzini kuzoncibilika ngokuqondile futhi akukwazi "ukubamba" umswakama; Ijeli ye-silicone evamile inomphumela omuhle ekukhangiseni umswakama ezindaweni ezinomswakama ophezulu, kodwa ukucwiliswa emanzini kungabangela ukumuncwa kwamanzi ngokweqile nokushesha, okuholela ekuqhekekeni; 5Isisefo samamolekyuli singahlukanisa initrogen nomhwamuko wamanzi osemoyeni, kodwa sinamandla okukhangisa amanzi anamandla. Ezimweni ezinomswakama ophezulu, imunca ngokushesha amanzi futhi igcwale, kube nomthelela omubi ekusebenzeni kahle kwayo kokuhlukaniswa kwezinye izinto.
