补充资料:醋酸纤维素膜
分子式:
CAS号:
性质:把纤维素乙酰化后,可以得到各种黏度等级的用于制备分离膜的醋酸纤维素膜材料,醋酸纤维素分离膜具有较好的分离性能,合理的耐氯性,而且成本低,所以至今仍用来制备反渗透膜、超滤膜、微孔滤膜和电泳膜等。但是由于醋酸纤维素反渗透膜脱盐率低于芳香聚酰胺类复合膜,使用压力也高,易被微生物水解,耐酸碱性差,不耐压,不耐温等缺点,因而单醋酸纤维素膜和二醋酸纤维素膜已较少使用。现在用二醋酸纤维素(CA)和三醋酸纤维素(CTA)按一定比例混合制成卷式和中空纤维反渗透膜,在硝酸纤维素和二醋酸纤维素的支撑膜上,复合以40~80nm的三醋酸纤维素反渗透膜等,由于其耐氯性和反渗透性能有提高,及其价格较低,至今仍是与复合反渗透膜同时销售的主要产品。醋酸纤维素超滤膜和微孔膜,常用作人工肾膜。
