3A sefa yemamorekuru

3A molecular seeve ialkali metal aluminate, dzimwe nguva inonziwo 3A zeolite molecular seeve.

Zita reChirungu: 3A Molecular Seeve
Chiyero cheSilica / aruminiyamu: SiO2/ Al2O3≈2
Saizi yepore inoshanda: inenge 3A (1A = 0.1nm)

Nheyo yekushanda kwesefa yemamorekuru inonyanya kuenderana nehukuru hwepore yesefa yemamorekuru, zvichiteerana 0.3nm/0.4nm/0.5nm, inogona kunyudza mamorekuru egasi ane dhayamita yemamorekuru idiki pane saizi yepore, uye saizi yepore yakakura, kugona kwemushonga kunowedzera. Saizi yeporeru yakasiyana, uye zvinhu zvakaseferwa zvakasiyana. Muchidimbu, sefa yemamorekuru ye3a inogona kunyudza mamorekuru ari pasi pe0.3nm chete.

3A molecular sese ine saizi ye3A, iyo inonyanya kushandiswa kunyudza mvura, uye hainyudze chero molecular ine dhayamita yakakura kupfuura 3A. Zvichienderana nehunhu hwekushandiswa kwemaindasitiri, molecular sese ine kukurumidza kunyudza, nguva yekuvandudzwa, simba rekupwanya uye kugona kudzivirira kusvibiswa, izvo zvinovandudza kushanda zvakanaka kwemolecular sese uye zvinowedzera hupenyu hwebasa remolecular sese. Chinhu chinodiwa chekunyudza kuti kuome zvakanyanya, kunatswa uye kupometa gas-liquid phase muindasitiri yepetroleum nemakemikari.
