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、聚四乙烯全隔膜为材料的套管式隔膜电解槽具有隔膜亲水性强、电阻小、耐碱腐蚀、耐铁酸盐氧化等优点，与平板式隔膜电解槽采用的普通玻硼硅玻相比是更加理想的电化学合成铁酸盐的电解槽及隔膜材料。
