补充资料:电解食盐水溶液离子膜电解槽所用的膜材料之一
分子式:
CAS号:

性质:又称全氟羧酸-磺酸复合离子膜  Rf-COOH-Rf-SO3H  电解食盐水溶液离子膜电解槽所用的膜材料之一。使用时,将较薄的羧酸层面向阴极,较厚的磺酸层面向阳极,因而兼有羧酸膜和磺酸膜的优点。由于Rf-COOH层的存在,可阻挡氢氧离子返迁移到阳极室,确保了高的电流效率(96%),因Rf-SO3层的电阻低,能在高电流密度下运行,且阴极液可用盐酸中和,产品氯气中氧含量低,氢氧化钠浓度可达33%~35%。可在全氟磺酸膜上涂敷一层全氟羧酸的聚合物,或是将磺酸膜和羧酸膜进行层压,或是采用化学方法处理而制得的复合膜。现以采用化学方法处理者质量最佳。
