采用二次生长法在管状莫来石载体外表面制备了NaA分子筛膜。载体表面对制得的NaA分子筛膜的质量有明显的影响。比较了浸渍法、摩擦法和摩擦-浸渍法三种晶种对NaA分子筛膜质量的影响。浸涂处理可以在载体表面的平坦区域提供均匀分布的种子，但对凹陷和针孔的覆盖较差。然而，用种子膏摩擦处理可以优先将种子提供到缺陷中，但在平坦区域上的覆盖不均匀。复合接种法优于前两种接种法，制得的膜性能好，重复性好。
NaA zeolite membranes were prepared by secondary growth on the outer surface of tubular mullite supports. Support surface was found to have obvious effect on the quality of as-made NaA zeolite membranes. Three seeding methods were compared for the quality of as-made NaA zeolite membranes, which included dip-coating, rubbing, and the combination of rubbing and dip-coating. The dip-coating treatment could provide well-distributed seeds on flat area of support surface, but poor coverage on dents and pinholes. Rubbing treatment with seed paste, however, could preferentially provide seeds into the defects but non-uniform coverage on the flat area. The combined seeding approach was better than the former two seeding methods, which produced high performance membranes with high reproducibility.
