【摘要】 以PVC/PMMA合金为膜材料 ,研制出了具有非对称断面结构的微滤膜。经优化后膜的平均孔径为 0 .18-9.2 8μm ,在 0 .1MPa操作压力下膜的纯水通量可高达 2 2 0 0 0L/m2 ·h。对影响膜结构与性能的若干因素也进行了探讨。更多还原

【Abstract】 Asymmeric PVC/PMMA alloy microfiltration membranes were prepared via phase inversion.The membranes optimized have average pore size of 0.18-9.28 μm with the highest pure water flux of 22 000 L/m 2·h under pressure of 0.1 MPa. Effect of some factors on membrane structure and performance was studied.更多还原
