| 摘 要： | 运用红外光谱法(IR)分析了某种贮存十年弹药中引信锈蚀产物、贮存一年的紫色发烟弹"鼓气"气体产物、模拟紫色发烟弹长贮过程材料化学结构的变化。结果表明,某引信失效的主要原因是弹药中炸药组分聚醋酸乙烯酯降解为醋酸,醋酸扩散至引信内部导致金属材料的腐蚀。紫色发烟弹失效的主要原因是其中的NaHCO3加速碱性玫瑰精分解产生"鼓气"和使用变色的失效。根据分析结果提出了引信和发烟弹的失效机理和延缓失效的措施。

| Abstract: | Infrared spectroscopy technique was used to analyse the corrosion products from certain ammunition exploder stored for 10 years,"blast gas" from smoke composition stored for 1 year and chemical structure change of materials in smoke composition simulatedly stored for years.The results show that,the main reason for the ammunition exploder falure is that PVAC is degraded to HAc,and HAc diffuses to exploder inside leading to its corrosion.The main reason for the smoke composition falure is that NaHCO3 accelerates Rhodamine B Extra decomposition and releases gas.Failure mechanism of certain ammunition and smoke composition and prevention failure measurements were proposed. |
