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.
