4A molecular sieve & 13X molecular sieve

4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O₃
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm molecular sieve yog feem ntau cuam tshuam nrog qhov pore loj ntawm molecular sieve, uas tuaj yeem nqus cov pa roj molecules uas nws txoj kab uas hla ntawm lub pore me dua qhov pore loj, thiab qhov loj dua qhov pore loj, lub peev xwm adsorption loj dua. Qhov loj ntawm qhov aperture txawv, thiab cov khoom lim tau txawv. 4a molecular sieve, cov adsorbed molecules kuj yuav tsum tsawg dua 0.4nm
4A molecular sieves feem ntau yog siv los ua kom qhuav cov pa roj thiab ntau yam tshuaj lom neeg thiab cov kua dej, cov tub yees, tshuaj, cov ntaub ntawv hluav taws xob thiab cov khoom tsis zoo, ua kom huv argon, thiab cais cov methane, ethane thiab propane. Feem ntau yog siv rau kev ziab kom qhuav ntawm cov pa roj thiab cov kua dej xws li cua, nkev roj, hydrocarbons thiab refrigerants; Kev npaj thiab purification ntawm argon; Static drying ntawm cov khoom siv hluav taws xob thiab cov khoom siv perishable; Dehydrating agents nyob rau hauv cov xim, polyesters, dyes thiab coatings.

13X hom molecular sieve, tseem hu ua sodium X hom molecular sieve, yog ib qho alkali hlau silicaluminate, muaj qee yam alkaline, belongs rau cov chav kawm ntawm cov khoom hauv paus.
Nws cov tshuaj formula yog Na2O·Al2O3·2.45SiO2·6.0H20,
Nws qhov pore loj yog 10A thiab nws adsorbs ib qho molecule ntau dua 3.64A thiab tsawg dua 10A
13x yog siv rau hauv:
1) Gas purification nyob rau hauv cov huab cua sib cais cov khoom kom tshem tawm cov dej thiab carbon dioxide.
2) Kev ziab thiab desulfurization ntawm cov pa roj ntsha, roj av liquefied thiab kua hydrocarbons.
3) General gas tob kom qhuav. 13X hom molecular sieve, tseem hu ua sodium X hom molecular sieve, yog ib qho alkali hlau silicaluminate, muaj qee yam alkaline, belongs rau cov chav kawm ntawm cov khoom hauv paus.
