摘要:

研究了硝酸铵在在100～150 ℃之间热分解的机理和影响因素,并定量分析了使系统活化的物质和稳定剂的作用.研究结果表明:水分、硝酸、硫酸、磷酸可降低系统的热稳定性,其质量含量达0.5%可以使硝酸铵感应期缩短50%以上;添加3%氧化锌和氢氧化铝能够有效抑制分解反应;对于碳酸钙和氯化钾,只有当质量含量达到15%时,分解反应不再进行;尿素是一种良好的硝酸铵稳定剂,在130 ℃,含量1%即可抑制分解反应.

Abstract:

The mechanism and influencing factors of thermal decomposition of ammonium nitrate between 100~150 °C were studied, and the effects of substances and stabilizers that activated the system were quantitatively analyzed. The results show that moisture, nitric acid, sulfuric acid and phosphoric acid can reduce the thermal stability of the system, and its mass content of 0.5% can shorten the induction period of ammonium nitrate by more than 50%. The addition of 3% zinc oxide and aluminum hydroxide can effectively inhibit the decomposition reaction; For calcium carbonate and potassium chloride, the decomposition reaction is no longer carried out only when the mass content reaches 15%; Urea is a good ammonium nitrate stabilizer, which can inhibit the decomposition reaction at 130 °C at 1% content.
