Isebenza njani iSieve yeMolekyuli
Izinto ezisetyenziswa kwi-industrial molecular sieve zineepores ezincinci ezifanayo. Xa ezinye izinto zidibana ne-molecular sieve, iimolekyuli ezinobungakanani obufanelekileyo ukuba zingene kwi-pores ziya kubhengezwa. Iimolekyuli ezinkulu kakhulu ukuba zingalingana aziyi. Iisefu ze-molekyuli zisebenza kwinqanaba le-microscopic, ngoko ke ubukhulu babo bulinganiswa kwii-angstroms. Iisayizi zePore 3Å kunye ne-4Å ziya kubhengeza amanzi ngelixa iisayizi ezinkulu zisusa iihydrocarbons ezinkulu.
Izixhobo zeSieve yeMolekyuli
Ngokwengqiqo engqongqo yesayensi, uninzi lwendalo lwe-desiccant desiccant dehumidifiers njengekalika, udongwe kunye nejeli ye-silica nazo zisebenza ngokuhluza iimolekyuli zomphunga wamanzi, kodwa iisefu zemolekyuli zentengiso zenziwe nge-synthetic crystalline aluminosilicates. Ngokungafaniyo ne-desiccants efunyenwe kwindalo, ukulawulwa kobukhulu be-pore ngexesha lokwenziwa kuvelisa iimpawu ezikhethiweyo ze-adsorption.
Izinto eziluncedo kwiiSieves zeMolekyuli
I-molecular sieves idla ngokukhawuleza amanzi ngokukhawuleza kunezinye i-desiccant dryer kwaye inokunciphisa umswakama ukuya kumanqanaba aphantsi kakhulu kwijeli ye-silica. Zikwasebenza ngakumbi kune-desiccants yendalo yezicelo ezidlula ukushisa kwegumbi eliqhelekileyo. Xa zisetyenziswe ngokufanelekileyo, zinokusebenza ekunciphiseni iimolekyuli zamanzi ziphantsi njenge-1ppm kwizikhongozeli ezikhethekileyo okanye kwi-10% yomswakama onxulumene nokupakishwa.

Ukungalungi kweeSieves zeMolekyuli
Amaxabiso aphakamileyo kunezinye iindlela ze-desiccant desiccant dehumidification; nangona kunjalo, iisefu zemolekyuli nazo zisebenza ngakumbi. Iindleko ezichanekileyo ngeyunithi nganye kunye nexabiso lokugqibela liya kuxhomekeka kwezinye izinto ezifana nomthamo oza kuncitshiswa kunye nenqanaba lokomisa elifunekayo. Izisefu zeemolekyuli, ngelixa zivunyiwe ukuba zisetyenziswe kunye namayeza eYurophu, azikavunywa yi-FDA malunga nokutya okanye amayeza e-US.
Izisefu zemolekyuli zinesakhono esigqwesileyo kunye namazinga e-adsorption, nakumaqondo obushushu aphezulu. Zizo kuphela i-desiccant ekhethiweyo kwisayizi ye-molecular.
Ukuhlaziywa kunye nokuSetyenziswa kwakhona kweeSieves zeMolekyuli
Ngelixa ezinye iisefu zemolekyuli ezisusa i-alcohols kunye ne-aromatics hydrocarbons zisebenzisa uxinzelelo ukuvuselela i-sieve, iisefu zemolekyuli ezisetyenziselwa ukubhengezwa kwamanzi zihlala zivuselelwa ngokufudumeza. Kwiinjongo ezininzi zemizi-mveliso, la maqondo obushushu aqala malunga ne-250 ° ukuya kwi-450 ° F, afana nemimiselo yokushisa yokubhaka kwi-oven yasekhitshini eqhelekileyo.
