3A Molecular Sieve
-
Dej Caw Dej hauv Distillation Ntauwd / Desiccant / Adsorbent / Hollow iav molecular sieve
Molecular sieve 3A, tseem hu ua molecular sieve KA, nrog rau qhov aperture ntawm li 3 angstroms, tuaj yeem siv rau ziab cov roj thiab cov kua dej nrog rau lub cev qhuav dej ntawm hydrocarbons.Nws kuj tseem siv dav rau kev ziab kom tiav ntawm roj av, tawg gases, ethylene, propylene thiab natural gases.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm molecular sieves yog feem ntau cuam tshuam nrog qhov pore loj ntawm molecular sieves, uas yog 0.3nm / 0.4nm / 0.5nm feem.Lawv tuaj yeem nqus cov pa roj molecules uas nws txoj kab uas hla molecular me dua qhov pore loj.Qhov loj ntawm qhov loj ntawm qhov pore loj, qhov muaj peev xwm adsorption ntau dua.Qhov pore loj txawv, thiab cov khoom uas lim thiab sib cais kuj txawv.Hauv cov ntsiab lus yooj yim, 3a molecular sieve tuaj yeem tsuas yog adsorb molecules hauv qab 0.3nm, 4a molecular sieve, cov adsorbed molecules kuj yuav tsum tsawg dua 0.4nm, thiab 5a molecular sieve yog tib yam.Thaum siv los ua desiccant, molecular sieve tuaj yeem nqus tau txog 22% ntawm nws tus kheej qhov hnyav hauv cov dej noo.
