华运软管泵在新能源锂电行业中的应用

锂电池主要由正极材料、负极材料、电解液、隔膜四大部分组成。锂电池在原料制备阶段的浆料输送、后期的废液污水处理上都广泛使用软管泵。

一:正极材料制备阶段:软管泵在此环节中可应用于原料/辅料投加泵,帮助溶剂、粘接剂等液体添加剂输送至混合釜;将原料泵送至混合釜。

二、正负极涂布/拉浆:由于用于涂布的混合浆液有一定温度,粘度2000~8000cps左右,需要低起泡输送,并需具有耐酸性,软管泵可很好地符合这些工艺要求,应用于浆料输送中,将混合后的正极/负极材料泵送至涂布机或暂存罐。

三、组装化成:电池生产中的组装化成需要将半成品的正负极制片与隔膜进行组装,注入电解液,并根据电池不同种类进行封装。组装化成阶段的电解液灌注量非常小,定量要求高;电解液的腐蚀性对接液部件的材质有一定要求;并且上料要求低起泡、避免产生过大剪切力。软管泵在此最典型的应用是电解液上料。上料泵可用于配套与灌注机上,或单独作为工艺泵选购与产线上。

四、锂离子电池和蓄电池的生产过程中均会会产生重金属、酸液等污水,紧随其后的污水处理也是电池行业非常重要的一个环节。废水处理的多个环节可以用到软管泵。


华运软管泵广泛运用于:

硫酸镍、氢氧化钠、上清液输送;

各种粘合剂、溶剂介质输送;

各种浆料输送;

污水处理中的压滤机供料、加药等;
