关于蓄电池正极板添加剂

目前对正极添加剂使用方面相当慎重，成熟的发孔剂有SiO2、K2SO4海泡石粉（精制白蟹）等，一般用量0.02％-0.1％。导电剂有石墨、碳纤维等，用量在0.1%-0.3%范围。最新采用镀锡的微珠玻璃，既发孔又导电，效果显著。这些添加剂，特别是负极膨胀剂，其中有机膨胀剂在铅青中会对铅膏相组成产生影响。活性物质的脱落是可以抑制的，采用强化剂与完善固化工艺可以实现。但必须注意负极膨胀剂硫酸钡绝对不容许混人正极，因为PbO2的结构在硫酸钡存在下会迅速被破坏。

Use aspect equal circumspect to the cathode additive currently, the mature hair bore has SiO2, and the K2 SO4 sea bubble stone powder(is refined white crab)...etc., general the dosage is 0.02%-0.1%.Conduct electricity to there are graphite, and carbon fiber...etc., the dosage is in 0.1%-0.3% scopes.Lately adopt tin-plating tiny bead glass, since the hair bore conducts electricity again, the effect shows Zhao.These additive, especially anode inflation, among them, the organic inflation is green in the lead in will mutually constitute creation influence to the lead cream.The sheding off of activity material can repress, the adoption enhances and perfect solid chemical engineering skill to carry out.But have to notice an anode inflation the sulfuric acid barium absolutely allow of no Xu Hun Ren's cathode, because the structure of the PbO2 exists in the sulfuric acid barium under will quickly be broken.  http://www.dc3688.com
