本文介绍了在ＵＪ５２多量限电位差计中用ＬＭ３９９代替锌汞电池的电路和方法。
Improvement study of the quality of mercury-free battery zinc powder;
提高无汞电池锌粉质量的研究
R&D and industrialization of mercury-free R20S & R14S batteries;
无汞锌锰糊式电池的研发及产业化
The homemadematerials and fittings,such as zinc-powder,electrolytic man-ganese dioxide(EMD),separate paper and current collector for mercury-freealkaline Zn/MnO 2 battery were described.
重点叙述了无汞碱性锌锰电池用锌粉、电解二氧化锰、隔膜纸和铜钉等国产材料和配件的试验情况,并与国外进口材料作了对比分析;分析结果表明:国产优质无汞碱锰电池专用电解二氧化锰(EMD)产品的质量已达到了日本同类产品水平,但锌粉、隔膜、铜钉等与国外同类产品相比仍有差距,需要大家共同努力攻关,达到降低无汞碱锰电池成本、提高国际竞争能力之目的。
