引燃式烟雾剂的配制及应用研究

Study on the Compounding and Application of Kindled Smoke Generator

目的：探讨防制卫生害虫的引燃式烟雾剂配制方法及应用。方法：根据引燃式烟雾载药技术原理和经济简便的原则，实验研究合理的配制方法及杀虫效果。结果：以敌敌畏、木屑、氯酸钾、硫酸铵和白陶土为原料，按比例配制的烟雾剂，易点燃，无明火，残渣无余火，燃烧最高温度２６８～２９０℃，杀虫剂成烟率９５％以上，９０℃以下不自燃。０．２ｇ／ｍ３熏杀淡色库蚊，杀灭率１００％；３～５ｇ／ｍ３现场灭蟑螂，对日本大蠊及美洲大蠊杀灭率达９０％～９５％以上。结论：该烟雾剂配方合理，配法简便，使用方便，效果显著。

Objective:To probe into the compounding method and application of kindled smoke generator.Method:We studied the reasonable compounding method and the effect according to the technical principle of kindled smokecarryinginsecticide and the principle of thrifty and simplicity.Result:The compounded smoke generator was easy to be kindled,and can not spontaneously ignite below 90℃.Its highest temperature of combustion was 268℃-290℃.The smoke generating rate of insecticide was above 95%.The leftovers have not remained fire.With 0.2g/m3 smoke generator,the killing rate of Culex pipiens pallens was 100%.With 3-5 g/m3 smoke generator,the killing rate of Periplaneta japonica and Periplaneta americana were above 90-95%.Conclusion:These data indicate that this smoke generator has reasonable prescription,simple compounding method,and remarkable effect.
