Molecular sieve lub cev qhuav dej yog cov tshuaj muaj txiaj ntsig zoo rau cov kuab tshuaj kom qhuav, dav siv hauv tshuaj, tshuaj, petrochemical, thiab hluav taws xob kev lag luam. Nws ua kom cov dej noo tshem tawm mus rau qib ppm yam tsis qhia impurities.
Molecular sieves yog crystalline aluminosilicates nrog cov pore sib txawv ntawm 3Å txog 10Å (0.3–1.0 nm). Hauv cov txheej txheem ziab kom qhuav, lawv ua haujlwm los ntawm kev tshem tawm qhov loj me thiab polar adsorption. Cov dej molecules (~ 2.75Å) yooj yim nkag mus rau hauv lub qhov hws thiab muaj zog adsorbed, thaum loj dua cov kuab tshuaj molecules dhau los, ua rau kom huv thiab ua kom lub cev qhuav dej.
Hom Molecular Sieves rau Solvent Drying
3A Molecular Sieve (3Å)
Zoo tagnrho rau cov kuab tshuaj polar xws li ethanol, methanol, thiab acetonitrile. Feem ntau siv hauv roj ethanol lub cev qhuav dej kom ua tiav txog 99.995% purity.
4A Molecular Sieve (4A)
Ib qho kev xaiv ntau yam rau cov kuab tshuaj kom qhuav, suav nrog THF, DMF, dichloromethane, thiab cov kuab tshuaj tsw qab. Siv dav hauv lithium roj teeb electrolyte hnyav kom qhuav, qhov chaw noo noo yuav tsum qis dua 20 ppm.
5A Molecular Sieve (5Å)
Haum rau hydrocarbons xws li n-hexane, cyclohexane, thiab kerosene. Pab txhim kho kev noj zaub mov zoo thiab tiv thaiv cov kab mob hauv qab.
13X Molecular Sieve (10Å)
Tsim los kom qhuav qhuav ntawm cov molecules loj thiab siab - cov kuab tshuaj boiling xws li hnyav aromatics thiab aviation roj.
Vim li cas thiaj xaiv Molecular Sieve Dehydration?
Piv nrog rau cov txheej txheem ziab khaub ncaws, molecular sieve dehydration muaj:
Ultra-qe noo noo (ppm ntau)
Tsis muaj tshuaj lom neeg
Regeneable thiab reusable
Stable ntev - kev ua tau zoo
Xaus
Xaiv txoj cai molecular sieve (3A, 4A, 5A, los yog 13X) ua kom cov kuab tshuaj kom qhuav kom zoo, txo cov kuab tshuaj poob, thiab txo cov nqi khiav lag luam, ua rau nws cov kev daws teeb meem zoo tshaj plaws rau cov txheej txheem dej qhuav niaj hnub no.
