3A gwangwani kwayoyin

3A kwayoyin sieve ne alkali karfe aluminate, wani lokacin kuma shi ake kira 3A zeolite kwayoyin sieve.

Sunan Ingilishi: 3A Molecular Sieve
Silica / aluminum rabo: SiO2 / Al2O3≈2
Girman pore mai inganci: kusan 3A (1A = 0.1nm)

Ka'idar aiki na sieve kwayoyin yawanci yana da alaƙa da girman pore na sieve na ƙwayoyin cuta, bi da bi 0.3nm/0.4nm/0.5nm, suna iya tallata ƙwayoyin iskar gas waɗanda diamita na ƙwayoyin cuta ya fi girman pore, kuma mafi girman girman pore, ya fi girma ƙarfin adsorption. Girman budewar ya bambanta, kuma abubuwan da aka tace sun bambanta. A cikin sassauƙan kalmomi, 3a ƙwanƙwasa ƙwayar ƙwayar cuta zai iya jujjuya ƙwayoyin da ke ƙasa da 0.3nm.

3A molecular sieve yana da girman rami na 3A, wanda galibi ana amfani da shi don shayar da ruwa, kuma baya shayar da kowane kwayar halitta mai diamita fiye da 3A. Dangane da halaye na aikace-aikacen masana'antu, ƙwayar ƙwayar ƙwayar cuta tana da saurin adsorption da sauri, lokutan sabuntawa, murƙushe ƙarfi da ikon hana gurɓataccen gurɓataccen abu, wanda ke haɓaka ƙimar amfani da keɓaɓɓen ƙwayar ƙwayar ƙwayar cuta kuma yana haɓaka rayuwar sabis na sieve kwayoyin. Yana da mahimmancin kayan talla don bushewa mai zurfi, tsaftacewa da kuma polymerization na lokaci na ruwa-ruwa a cikin man fetur da masana'antun sinadarai.
