4A
Siv:
Feem ntau siv rau qhov tob ntawm huab cua qhuav, roj, alkanes, roj refrigerant thiab kua; Argon roj ua thiab ntxuav, ntim tshuaj, cov khoom siv hluav taws xob thiab cov khoom hloov pauv tau zoo li qub thiab qhuav; Ua tus neeg sawv cev dehydrating hauv xim, txheej, roj.
Kev Ua Tau Zoo:
Lub 4A molecular sieve muaj qhov loj li 4A, nws nqus tau dej, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene thiab propylene, thiab tsis muaj qhov loj tshaj 4A molecular sieve (xws li propane). Qhov kev xaiv ntawm kev nqus dej zoo dua li lwm cov molecular sieve, thiab yog ib hom molecular sieve loj tshaj plaws hauv kev lag luam.

5A
Siv:
Siv loj hauv kev nqus cua siab, kev ntxuav cua kom qhuav thiab carbon dioxide.
Kev Ua Tau Zoo:
5A molecular sieve bore diameter yog 5A, tuaj yeem nqus tau txhua yam molecular uas bore diameter tsis loj dua qhov no, feem ntau yog siv rau hauv heterogeneous hydrocarbon sib cais, siab viav vias nqus sib cais, tag nrho nqus dej thiab dioxide. Raws li 5A molecular sieve daim ntawv thov ntawm kev lag luam yam ntxwv, peb tsim cov nqus siab dua thiab nqus sai dua 5A molecular sieve, tshwj xeeb tshaj yog siv rau hauv siab viav vias nqus, tuaj yeem hloov kho rau txhua yam ntawm qhov loj me ntawm oxygen, hydrogen, carbon dioxide thiab lwm yam roj siab viav vias nqus khoom siv, yog cov khoom zoo hauv kev lag luam siab viav vias nqus.
