electric resistance 托福

PVC, Teflon and fluorion diaphragm were found to be better than glass as materials of diaphragm cell for their advantages in corrosion resistance as well as less electric resistance.

以聚氯乙烯、聚四氟乙烯和全氟离子隔膜为材料套管式隔膜电解槽具有隔膜亲水性强、电阻小、耐碱腐蚀、耐高铁氧化等优点，与平板式隔膜电解槽采用普通玻璃和高硼硅玻璃相比是更加理电化学合成高铁电解槽及隔膜材料。
