Amathiphu Okuthenga Izisefo Zemolekyuli

Indlela Isisefo Semolekyuli Esebenza Ngayo

Izinto ezisetshenziswa esisefweni samangqamuzana ezimboni zinezimbotshana ezincane ezifanayo. Lapho ezinye izinto zihlangana nesisefo samangqamuzana, ama-molecule anosayizi ofanele ukungena ezimbotsheni azokhangiswa. Ama-molecule amakhulu kakhulu ukuthi angalingana ngeke. Izisefo zamangqamuzana zisebenza ezingeni le-microscopic, ngakho-ke ubukhulu bawo bulinganiswa ngama-angstrom. Osayizi bembotshana 3Å kanye no-4Å bazokhangisa amanzi kuyilapho osayizi abakhulu besusa ama-hydrocarbon amakhulu.

I-Molecular Sieve Materials

Ngomqondo oqinile wesayensi, ama-desiccant desiccant amaningi emvelo afana nejeli ye-lime, ubumba ne-silica nawo asebenza ngokusefa amangqamuzana omhwamuko wamanzi, kodwa amasefa amangqamuzana okuhweba enziwe ngama-synthetic crystalline aluminosilicates. Ngokungafani nama-desiccants atholakala emvelweni, ukulawulwa kosayizi we-pore ngesikhathi sokukhiqiza kukhiqiza izici ezikhethiwe ze-adsorption.

Izinzuzo Zezihlungi Ze-Molecular

Izisefo zamangqamuzana ngokuvamile zikhangisa amanzi ngokushesha kakhulu kunamanye ama-dryer air desiccant futhi zinganciphisa umswakama emazingeni aphansi kakhulu kunejeli ye-silica evamile. Futhi zisebenza kangcono kunama-desiccants emvelo wezinhlelo zokusebenza ezedlula izinga lokushisa elivamile legumbi. Uma esetshenziswe kahle, angasebenza ngempumelelo ekwehliseni ama-molecule amanzi aphansi njenge-1ppm ezitsheni ezikhethekile noma abe ngu-10% womswakama ohlobene emaphaketheni.

Ukungalungi kwama-Sieves we-Molecular

Amanani aphakeme kunezinye izinhlobo ze-desiccant dehumidification; nokho, izisefo zamangqamuzana nazo zisebenza kahle kakhulu. Izindleko zangempela ngeyunithi ngayinye kanye nenani lokugcina kuzoncika kwezinye izici ezifana nevolumu ezosuswa umswakama kanye nezinga lokomisa elidingekayo. Izisefo zamamolekyuli, ngenkathi zigunyazwe ukuthi zisetshenziswe nemithi e-Europe, azikagunyazwa i-FDA ngokudla noma kwemithi e-US.

Izisefo zamangqamuzana zinamandla amakhulu kanye namazinga okukhangisa, ngisho nasemazingeni okushisa aphakeme. Yiwo kuphela ama-desiccant akhetha usayizi wamangqamuzana.

Ukukhiqizwa Kabusha Nokusetshenziswa Kabusha Kwezisefo Zemolekyuli

Nakuba ezinye izisefo zamangqamuzana ezisusa utshwala nama-hydrocarbon anephunga elimnandi zisebenzisa ingcindezi ukuze zikhiqize kabusha isisefo, izisefo zamangqamuzana ezisetshenziselwa ukukhangiswa kwamanzi ngokuvamile zivuselelwa ngokufudumeza. Ngezinjongo eziningi zezimboni, lawa mazinga okushisa asukela ku-250° ukuya ku-450°F, afana nezilungiselelo zokushisa zokubhaka kuhhavini wasekhishini ojwayelekile.
