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为材料的套管式隔电解槽具有隔性强、电阻小、耐碱腐蚀、耐高铁酸盐优点，与平板式隔电解槽采用的普通玻璃和高硼硅玻璃相比是更加理想的电学合成高铁酸盐的电解槽及隔材料。
