存放时间过长的散装极板在装配前,必须用钢丝刷轻轻地刷极板表面的灰尘和氧化层,然后再用毛刷刷几遍,方可装配使用。同时,应注意不能把刚出厂不久的新极板同存放时间过长的极板混合装配使用。装有这种极板的蓄电池在配制电解液时,应比正常的电解液比重有所减小。这是因为极板存放时间过长,其表面落有灰尘并且受潮和接触空气生成氧化层,即使用钢丝刷和毛刷刷过,也难以刷净。如果采用的电解液比重和正常情况一样,相对来说就显得 Bulk plates that are stored for long periods of time must be gently brush-ed with dust and oxide on the surface of the plates before they are assembled, and then brush several times before being assembled. At the same time, care should be taken that new plates that have not been released from the factory should not be mixed with plates that have been stored for too long. Battery equipped with such a plate in the preparation of electrolyte, should be reduced than the normal proportion of electrolyte. This is because the plates are stored for too long and their surfaces are dusty and damp and come into contact with air to form an oxide layer, which is hard to clean even with brush brushes and brushes. If the electrolyte used and the proportion of the same as normal, relatively speaking, it appears
