Safety Assessment of a Gas Generating Chemicals for Air Bags

本文采用热分析、燃烧量热法和燃速测定法对气囊用气体发生剂叠氮化钠及其氧化剂混合物进行了安全性评价。(1)研究了粒度、结晶度、气氛、湿度和老化等因素对叠氮化钠热反应的影响，并在有关刊物上发表了有关结果（叠氮化钠的热分析：危险材料学报，出版中），还研究了叠氮化钠的机械力化学，并发表了结果研究了叠氮化钠及其与氧化剂的混合物的等温分解反应，得到了分解反应的速率方程和动力学参数。

Safety assessment of sodium azide and its mixtures with oxidizing agents, which are a gas generating chemicals for air bags, was carried out by thermal analysis, combustion calorimetry and burning rate measurement and the followingresults wereobtained.(1) Effect of some factors on the thermal reactivity of sodium azodeThe effect of particle size, crystallinity, atmosphere, moisture and aging on the thermal reaction of sodium azide was studied and the results were published in the related jurnal(Thermal analysis of sodium azide : Jurnal of Hazardous Materials, in press), Mechanochemistry of sodium azide was also studied and he resaults were published (Mechnochemistry of sodium azide : J.Explosie society of JAPAN, Vol.55, 4(1994)).The isothermal decomposition of sodium azide and its mixture with oxidizing agents was studied, and the rate equation and kinetic parameters for decomposition were obtained.
