3Sefa yemamorekuru

3A molecular sieve is alkali metal aluminate, dzimwe nguva inonziwo 3A zeolite molecular sieve.

Zita reChirungu: 3A Molecular Sieve
Silika / aluminium chiyero: SiO2 / Al2O3≈2
Inoshanda pore saizi: inenge 3A (1A = 0.1nm)

Nheyo yekushanda yemamorekuru sieve inonyanya kuenderana nesaizi yepore ye molecular sieve, zvichiteerana 0.3nm/0.4nm/0.5nm, vanogona kushambadza mamorekuru egasi ane dhayamita yemolecular idiki pane saizi yepore, uye yakakura saizi yepore, iyo yakakura iyo adsorption capacity. Saizi yeaperture yakasiyana, uye zvinhu zvakasefa zvakasiyana. Mumashoko akareruka, 3a molecular sieve inogona kungoshambadza mamorekuru pazasi 0.3nm.

3A molecular sieve ine saizi yepore ye3A, iyo inonyanya kushandiswa kushambadza mvura, uye haishambadzi chero molecule ine dhayamita inodarika 3A. Zvinoenderana nehunhu hwekushandiswa kwemaindasitiri, iyo molecular sieve ine kukurumidza adsorption kumhanya, nguva yekuzvarwa patsva, kupwanya simba uye anti-kusvibisa kugona, izvo zvinovandudza mashandisiro ekushandisa kwema molecular sieve uye inowedzera hupenyu hwesevhisi ye molecular sieve. Iyo inodiwa adsorption zvinhu pakuomeswa kwakadzika, kunatsa uye polymerization yegasi-chimvura chikamu mupetroleum nemakemikari indasitiri.
