| 目的 分析塑料弹药箱产生凝露的原因， 并寻找消除方法。方法 分别采用3种消除凝露的方法：改进箱口密封形式 （方法A）； 改进箱口密封形式， 箱内放置防潮剂 （方法B）； 改进箱口密封形式， 箱内放置防潮剂， 而且产品、 包装材料去湿处理 （方法C）， 然后在交变湿热环境下测量、 评估塑料箱内的温湿度变化。结果 采取3种措施后， 20 ℃时的箱内平均湿度： 方法A达85%， 并持续增加； 方法B至72%左右达到平衡； 方法C维持在51%左右。结论 封装时对产品、 包装材料进行去湿处理， 箱内放置防潮剂， 并改进箱口密封形式， 可阻隔外界空气的渗漏， 长期维持箱内相对湿度为50%左右， 可有效减少凝露的产生， 保证弹药的贮存质量。 |

| The aim of this work was to analyze the causes for condensation generated in plastic crates of ammunition, and explore approaches to eliminating condensation. In alternating hot and humid environment, temperature and humidity changes in the plastic crates were measured and evaluated after the implementation of the following methods to eliminate condensation, improved sealed form of caisson(method A), improved sealed form of caisson and placed moisture agent in the crates(method B), improved sealed form of caisson, placed moisture agent in the crates and reduced the moisture content in the products pre-packaged and the packaging material (method C). After taking the three measures, the average humidity at 20 ℃： A reached 85%, and continued to increase; B reached the balance point of 72%; C maintained at about 51%. Therefore, reducing the moisture content in the packaging material and products pre-packaged, placing moisture agent in the crates and improving the sealed form of caisson, could block the outside air leakage, maintain the relative humidity level of 50% in the caisson for a long time, which could effectively reduce the generation of condensation, and guarantee the quality of ammunition during storage. |
