Sefa ye4A molecular & sefa ye13X molecular

4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O ₃
Nheyo yekushanda kwesefa yemamorekuru inonyanya kuenderana nehukuru hwemaburi esefa yemamorekuru, ayo anogona kunyudza mamorekuru egasi ane dhayamita yemamorekuru idiki pane saizi yemaburi, uye saizi yemaburi yakakura, kugona kwemushonga kunowedzera. Saizi yemusuwo yakasiyana, uye zvinhu zvakaseferwa zvakasiyana. 4a sefa yemamorekuru, mamorekuru akanyudzwa anofanirawo kunge ari pasi pe0.4nm
4A molecular seeves inonyanya kushandiswa kuomesa gasi rechisikigo nemagasi akasiyana-siyana emakemikari nezvinwiwa, mafiriji, mishonga, data remagetsi nezvinhu zvinoputika, kuchenesa argon, nekuparadzanisa methane, ethane nepropane. Inonyanya kushandiswa pakuomesa magasi nezvinwiwa zvakaita semhepo, gasi rechisikigo, mahydrocarbon nemafiriji; Kugadzirira nekucheneswa kweargon; Kuomesa zvinhu zvemagetsi nezvinhu zvinoora; Zvinobvisa mvura mumapendi, mapolyester, madhayi uye machira.

Sefa yemhando ye13X, inozivikanwawo sesefa yemhando yesodium X, isimbi yealkali silicaluminate, ine alkaline yakati, uye iri muboka rezvigadziko zvakasimba.
Fomura yayo yemakemikari ndeye Na2O· Al2O3·2.45SiO2·6.0H20,
Saizi yepore yayo i10A uye inosveta chero molekyuru yakakura kupfuura 3.64A uye iri pasi pe10A
Iyo 13x inonyanya kushandiswa mu:
1) Kuchenesa gasi muchishandiso chekuparadzanisa mhepo kubvisa mvura nekabhoni dhayiokisaidhi.
2) Kuomesa uye kubvisa sarufa yegasi rechisikigo, gasi repetroleum rakanyungudutswa uye mahydrocarbon emvura.
3) Kuomesa kudzika kwegasi. Sefa yemhando ye13X, inozivikanwawo sesefa yemhando yesodium X, isimbi yealkali silicaluminate, ine alkaline yakati, iri muboka rezvigadziko zvakasimba.
