Mazano eKutenga Masefa eMolecular

Mashandiro Anoita Sefa Yemamorekuru

Izvo zvinoshandiswa muindasitiri yemamorekuru sieve ine madiki mayunifomu pores. Kana zvimwe zvinhu zvasangana nesefa yemamorekuru, mamorekuru ari saizi yakakodzera kukwana mumapores anozoshambadzirwa. Mamorekuru akakurisa kuti akwane haaite. Masefa mamorekuru anoshanda pamwero wemicroscopic, saka saizi yawo inoyerwa mumangstroms. Pore ​​size 3Å uye 4Å anoshambadza mvura ukuwo mahombe achibvisa mahydrocarbons akakura.

Molecular Sieve Zvishandiso

Mupfungwa yesainzi, akawanda echisikigo desiccant dehumidifiers serimu, ivhu uye silica gel anoshandawo nekusefa mamorekuru emhute yemvura, asi ekutengesa mamorekuru sieve anogadzirwa nesynthetic crystalline aluminosilicates. Kusiyana nema desiccants anowanikwa mumasikirwo, kutonga kwehukuru hwepore panguva yekugadzira kunoburitsa yakasarudzika adsorption maitiro.

Zvakanakira zveMolecular Sieves

Masieves emu molecular anowanzo sveta mvura nekukurumidza kupfuura mamwe ma desiccant air dryer uye anogona kuderedza hunyoro kusvika kumazinga akaderera ayo akajairwa silica gel. Iwo zvakare anoshanda zvakanyanya kupfuura echisikigo desiccants kune maapplication anopfuura yakajairika tembiricha yekamuri. Kana akashandiswa nemazvo, anogona kushanda mukudzikisa mamorekuru emvura akadzika se1ppm mumidziyo ine hunyanzvi kana 10% hunyoro hwehukama mukurongedza.

Zvakaipa zveMolecular Sieves

Mitengo yakakwirira kudarika mamwe maitiro e desiccant dehumidification; zvisinei, ma molecular sieves anoshandawo zvakanyanya. Iwo chaiwo mitengo payuniti uye kukosha kwekupedzisira kunotsamira pane zvimwe zvinhu zvakaita sevhoriyamu yekubviswa humidified uye nhanho yekuoma inodiwa. Masefa emorekuru, nepo akatenderwa kushandiswa nemishonga muEurope, haana kubvumidzwa neFDA zvechikafu kana mishonga muUS.

Masefa emamorekuru ane hunyanzvi hwekugona uye mazinga eadsorption, kunyangwe pakakwirira tembiricha. Ndivo chete desiccant iyo inosarudza yekukura kwema molecular.

Kuzvarwa patsva uye Kushandiswazve kweMolecular Sieves

Nepo mamwe masefa emamorekuru anobvisa madoro nemahydrocarbon anonhuwirira anoshandisa kudzvanya kuti agadzirise sefa, masefa emamolecular anoshandiswa pakuita mvura-adsorption anowanzo kuvandudzwa nekudziya. Nokuda kwezvinangwa zvakawanda zvemaindasitiri, tembiricha idzi dzinobva pa250° kusvika 450°F, zvakafanana netembiricha yekubikira yevheni yekicheni yakajairwa.
