通过对钠离子在高吸水性树脂吸水过程中的迁移行为的研究,得出:在树脂吸水过程中,钠离子会发生迁移或者说被氢离子交换,不会一直处于树脂网络中,但最终钠离子又回到网络中。钠离子这一行为决定了树脂的吸水过程。又通过不同水环境(一个是静止状态的去离子水,一个是流动状态的去离子水)的吸水过程的考察,进一步阐述和证实了钠离子的行为对高吸水性树脂吸水过程的影响。
Through the study of the migration behavior of sodium ions in the process of water absorption of superabsorbent polymer, it is concluded that during the absorption of resin, sodium ions will migrate or be exchanged by hydrogen ions and will not always stay in the resin network. However, the final sodium The ions are back in the network. This behavior of sodium ion determines the resin’s water absorption process. The effect of sodium ion on the water absorption process of superabsorbent polymer was further elaborated and confirmed through the investigation of water absorption process in different water environments (one is de-ionized water in quiescent state and the other is deionized water in flowing state).
