针对传统电解加工存在的易造成环境污染等问题,本文提出使用纯水作为电解液的新思路,并将磺酸型阳离子交换树脂用金属离子改性后,在电解加工间隙进行填料。通过测量电流-电压特性曲线,研究了离子交换树脂对水解离的作用。实验结果表明:借助离子交换树脂用纯水作为电解加工的电解液具有可行性;树脂经与其亲和力较弱的阳离子改性后,强化了其催化解离纯水的能力,而用与其亲和力较强的阳离子改性后则表现较差。但进行负载修饰时,溶液中金属离子的浓度可能会影响到树脂上活性亲水位点的数量,而温度对树脂的催化性能具有一定的影响。
Aiming at the problems such as environmental pollution caused by traditional electrolytic processing, this paper proposes a new idea of using pure water as electrolyte and the sulfonic acid cation exchange resin is modified with metal ions to fill in the electrolytic process gap. The effect of ion exchange resin on the dissociation of water was investigated by measuring the current-voltage characteristic curve. The experimental results show that the use of pure water as ion exchange resin for electrolytic processing is feasible; the resin is modified by its weak affinity with cationic to strengthen its ability to catalyze the dissociation of pure water, while its affinity with strong The cationic modified poor performance. However, during loading modification, the concentration of metal ions in the solution may affect the amount of active hydrophilic sites in the resin, and the temperature has a certain influence on the catalytic performance of the resin.
