| 摘 要： | 活性二氧化锰生产过程中锰粉焙烧工艺对产品性能的影响较大 ,通过控制转化温度和保温时间均导致不同的焙烧效果。实验结果表明 ,焙烧充分时 ,产品的MnO2 百分含量会有所提高 ,但堆实密度会有所下降 ;焙烧不足时 ,产品的放电性能较差 ,焙烧产物的w(Mn4+ ) /w (Mn2 + )值接近 1时 ,活性锰放电性能比较理想 ,而焙烧过度时 ,产品的性能反而下降。

| Abstract: | The influence of manganese powder baking on the performances of activated chemical manganese dioxide (ACMD) was studied. The experiment results showed that with enough baking, the MnO 2 % of the product increased, but the tap density decreased; when the value w(Mn 4+ )/w(Mn 2+ )of baked manganese powder was about 1, the performances of ACMD were best. |
