烟花爆竹用氧化剂的研究进展

在调查研究的基础上,分析、总结、研讨用于烟花爆竹的氧化剂的历史、现状及发展方向。分析和讨论氯酸盐类、高氯酸盐类、硝酸盐类以及金属氧化物等氧化剂的物化性质、燃爆性能及各自用于烟火剂的优缺点。研究指出:将不同类型的氧化剂复合使用,当选择的组分及搭配的比例合适时,不仅能使各种氧化剂充分发挥其优点,而且还将产生一些新的实际的性能。同时提出:复合氧化剂是配制燃放效果好、安全性能高、价格低廉的烟花爆竹氧化剂的发展方向。

Research and Progress of Oxidants Used in Fireworks and Firecrackers

The history,actuality and development of oxidants used in fireworks and firecrackers are summarized and discussed based on investigation.The physical and chemical features of chlorate,high chlorate,nitrate and metallic oxides are analyzed;and their advantages and disadvantages are also discussed.The results show that the compounds of inhomogeneous oxidants have some new and actual capabilities if their components and proportion are appropriate.Finally it is pointed out that compound oxidants are the development trend of oxidants used in fireworks and firecrackers.
