3A molecular sieve

Sifet ɗin kwayoyin halitta na 3A aluminate ne na ƙarfe na alkali, wani lokacin ana kiransa sifet ɗin kwayoyin halitta na 3A zeolite.

Sunan Turanci: 3A Molecular Sieve
Rabon silica / aluminum: SiO2/Al2O3≈2
Girman rami mai inganci: kimanin 3A (1A = 0.1nm)

Ka'idar aiki na sieve na ƙwayoyin halitta tana da alaƙa da girman ramin sieve na ƙwayoyin halitta, bi da bi 0.3nm/0.4nm/0.5nm, suna iya ɗaukar ƙwayoyin iskar gas waɗanda diamita na ƙwayoyin halitta ya fi ƙanƙanta da girman ramin, kuma girman ramin ya fi girma, ƙarfin shawa ya fi girma. Girman buɗewar ya bambanta, kuma abubuwan da aka tace sun bambanta. A taƙaice, sieve na ƙwayoyin halitta na 3a zai iya ɗaukar ƙwayoyin halitta ne kawai ƙasa da 0.3nm.

Sifet ɗin kwayoyin halitta na 3A yana da girman ramin 3A, wanda galibi ana amfani da shi don shaƙar ruwa, kuma baya shaƙar kowace kwayar halitta mai diamita fiye da 3A. Dangane da halayen aikace-aikacen masana'antu, sifet ɗin kwayoyin halitta yana da saurin shaƙarwa, lokutan sake farfaɗowa, ƙarfin niƙawa da ikon hana gurɓatawa, wanda ke inganta ingancin amfani da sifet ɗin kwayoyin halitta kuma yana tsawaita rayuwar sifet ɗin kwayoyin halitta. Yana da kayan shaƙar da ake buƙata don bushewa mai zurfi, tsaftacewa da kuma polymerization na matakin iskar gas-ruwa a masana'antar mai da sinadarai.
