摘　　要：针对正生极板生产过程中出现的异常“黑芯”现象,使用XRD、分析化验等手段分析“黑芯”正生极板铅膏的物相组成,游离铅含量的变化和分布趋势等。结果表明,生极板温度和湿度过高时,铅膏中的游离铅不能充分氧化,导致单质铅过多,在极板外观上呈现出“黑芯”。We analyzed the abnormal phenomenon of"black core"in the production process of punched unformed positive plate,and investigated the phase composition,change and distribution trend of free lead content of lead paste of"black core"punched unformed positive plate by means of XRD and chemical analysis.The results show that the free lead in the lead paste can’t be fully oxidized when the temperature and humidity of the punched unformed positive plate are too high,resulting in too much elemental lead,showing an abnormal appearance of"black core".
