Khoom Taw Qhia
4A molecular sieve yog hais txog sodium A - hom silica aluminium, uas tuaj yeem nqus tau qhov tseem ceeb ntawm cov molecules hauv qab 4A.Nws tuaj yeem siv los nqus dej, carbon dioxide, cawv, olefins, thiab lwm yam. Peb 4A molecular sieve muaj qhov sib xws ntawm qhov channel, nqus dej loj, nrawm dua adsorption thiab qis dua qhov kub thiab txias.

Nco tseg: Cov saum toj no yog cov ntaub ntawv raug. Peb kuj tuaj yeem tsim raws li cov neeg siv khoom thov.
Daim ntawv thov tseem ceeb ntawm 4A molecular sieve
- Sib sib zog nqus ziab ntawm huab cua, nkev roj, alkane, tub yees thiab lwm yam roj thiab kua
- Kev npaj thiab purification ntawm argon
- Static ziab ntawm cov tshuaj ntim khoom, cov khoom siv hluav taws xob thiab cov khoom puas tsuaj
- Siv los ua tus neeg ua kom lub cev qhuav dej hauv cov xim, roj thiab coatings
Cov khoom ntim thiab khaws cia
Ntim: Hlau nruas / ntawv nruas / aluminium foil hnab los yog raws li tus neeg thov kev thov.
Cia: Tsis txhob damping thiab tej yam adsorption ntawm dej los yog organic tshuaj ua ntej siv. Txwv tsis pub nws yuav tsum tau regenerated.
FAQ
1.Yuav ua li cas yog 4A molecular sieve regenerated?
Lub peev xwm adsorption tuaj yeem rov tsim dua los ntawm thermal regeneration:
Txoj kev pa: Qhia cov cua qhuav los yog nitrogen ntawm 250-350℃thiab cua sov rau 4-6 teev;
Lub tshuab nqus tsev rov tsim dua: Kev sib xyaw nrog lub tshuab nqus tsev (tsawg dua 10 kPa) ntawm 150-250℃yields zoo dua;
Tom qab rov tsim dua tshiab, nws yuav tsum tau txias sai sai thiab kaw cia kom tsis txhob rov-hydration.
Lus Cim: Yog tias muaj kab mob los ntawm cov roj stains lossis cov kuab tshuaj organic, nws yuav ua rau lub cev tsis ua haujlwm tas mus li thiab nyuaj rau kev rov tsim dua tshiab.
2.Can 4A molecular sieves adsorb carbon dioxide?
Tseeb. Lub dynamic txoj kab uas hla ntawm CO₂ yog kwv yees li 3.3 Å, uas yog me dua lub pore txoj kab uas hla ntawm 4 Å (4.2 Å). Yog li ntawd, nws tuaj yeem ua tau zoo adsorbed. Cov cuab yeej no ua rau nws nquag siv rau:
Kev tshem tawm carbon dioxide los ntawm cov pa roj;
Tshem tawm CO₂ impurities hauv cov txheej txheem tsim khoom argon;
Kev lim dej hauv cov chaw kaw (xws li submarines, dav hlau.
