富液式隔板与普通隔板性能对比

Comparison in performance between flooded separator and common separator

通过对富液式隔板与普通AGM隔板性能的研究发现,富液式隔板与普通AGM隔板的浸酸失重,最大孔径、孔率、吸酸高度等物理性能基本没有差别,而两种隔板的基重、回弹性、可压缩率、抗拉强度、吸酸值等存在一定的差别。两种隔板组装成VRLA电池后,电池的某些性能相差较大(尤其电池的气体复合效率)。VRLA电池采用富液式隔板组装,可以在不影响电池的气体复合效率的前提下,适当增加电池的灌酸量从而提高电池的初期性能;并且可以解决VRLA电池的电解液提前"干涸"的问题,并延长电池的浮充使用寿命。通过增加电池灌酸量试验,发现电池灌酸量应该控制在合适的范围才能确保电池的气体复合效率。

The physical properties, such as the weight loss, the maximal pore size, the porosity, the height of acid absorption, etc, of folded separator are mostly similar to those of common AGM separator according to the study on the comparison in performance between them. However, there are differences between their basic weight, elasticity, compressibility, tensile strength and acid absorption value. Some performance of the valveregulated leadacid (VRLA) batteries assembled with the two separators has great difference, especially the gasrecombination efficiency. The initial performance of the VRLA battery assembled with folded separator is improved by increasing the amount of acid properly while the gasrecombination efficiency is not influenced. Moreover, the problem of electrolte dryout is solved and the floating serve life is extended by using the flooded separator. The acid amount in VRLA battery should be controlled in appropriate range in order to ensure the gasrecombination efficiency.
