蓄电池铅粉的特性

出于对铅酸蓄电池经济与技术方面的考虑，今天世界铅酸蓄电池工业几乎全部应用氧化铅粉作涂膏式极板与管式极板。基本的物理化学性质都与氧化铅粉的属性有关：a . PbO （氧化铅）所含的晶体变种（晶体类型）; b ．化学组成．c ．密度（真实密度、捣实密度、视密度）; d ．吸水量与吸酸值；e ．粒径大小与分布；f ．比表面积；9 ．孔隙度；h ．原料铅纯度与掺杂。
上述参数对控制生产过程的某些特性是重要的。主要目的是得到性能稳定的适合各个工艺过程与制造工序所必需的特性（化学组成、视密度、酸值及吸水量），另外一些特性（铅粉的晶体变种、粒子大小、孔隙度、比表面），对电池的寿命、容量产生直接影响并对电池性能产生最终影响。
测定铅粉特性相当重要，特别是对样品分析的可重复性。在大量样品中取样，在分析前必须考虑会改变铅粉性状的因素，比如铅粉样品暴露在大气中或潮湿气体里是不合适的。

Proceed from sour storage battery economy and the consideration of technique to the lead, the lead sour storage battery industry in world almost and all applies to oxidize ceruse to make the apply ointment type pole plank and the tube type pole plank today.The basic physical chemistry properties all have something to do with oxidizing the attribute of ceruse:a .The crystal mutation(crystal type) contained by PbO(plumbic oxide);B.the chemistry constitute. c.density;(true density and Dao solid density, see density)D.absorb water quantity with absorb a sour value;E.grain path size with distribute;F.accumulate than the surface;9.hole degree;H.raw material lead pure degree with blend.
The above-mentioned parameter is important to some characteristics of control production line.Main purpose is get a function stability of suit each craft process and manufacturing work preface the essential characteristic(the chemistry constitute, sees a density, sour value and absorbs water quantity), moreover some characteristics(the sub- size, hole degree of the crystal mutation, grain of ceruse, ratio surface), directly influence to combine to produce the end influence on battery function to the life span, capacity creation of battery.
Measurese ceruse characteristic equal importance, especially analyze to the sample of re-usable.Take a sample in a great deal of sample, at analytical ex- have to consider the factor that will change a ceruse form, for example the ceruse sample exposes in the atmosphere or isn't suitable in damp air.
