| 摘 要： | 在低压醋酸纤维素一丙酮－甲酰胺反渗船舶这膜铸膜液体体系中，加入二氧六环使膜具有较小的初始平均孔径和较窄的孔径分布，二氧六环起到了调节高分子网络尺寸变小和均一化的作用。在１．０ＭＰａ下进料液浓度为１０００ｍｇ／Ｌ时，膜对Ｎａ２ＳＯ４、ＭＧＳＯ４分离率〉９６％，对ＮａＣｌ为８０％，Ｃ（ＮＯ２）２为８０％，ＭｇＣｌ２为７９％。平均透水率〉１．２５ｍｌ／ｃｍ＾２．ｈ适用于中低盐度水的脱盐软化。

| Abstract: | Dioxane affects the dimension of the high molecular network when it is added to CA acetone formamhide solution, i.e. the initial average pore size of the membrane becomes small and the pore size distribution narrow. Typical CA acetone formamide dioxane low pressure RO membrane has salt rejection >96% for MgSO 4 and Na 2SO 4, >80% for MgCl 2 and flux>1 25ml/cm 2.h at 1.0MPa and solution concentration 1000mg/L. |
