目的 :探讨引燃式灭蟑烟雾剂的发烟效果评价指标及其最优配方。方法 :根据引燃式灭蟑烟雾剂的技术指标与经济简便原则 ,推断烟剂发烟效果评价指标 ,以及利用正交设计方法筛选出烟剂最优配方。结果 :以引芯点燃难易程度、有无明火、有无喷射状、平均发烟时间 (s/ 10 .0 g)、落下灰颗粒数 (颗 / 0 .2mm× 0 .2mm)及其分布均匀性 (颗粒分布变异系数表示 )等为发烟效果评价指标 ,考虑各评价指标的权重 ;遵照正交设计原理〔1〕,推断出烟剂最优配方。按最优配方配制的烟雾剂 ,用引芯易引燃、无明火、发烟较缓和、速度适宜 (约 30～ 5 0s/ 10g)、残渣无余火 ,燃烧完全 ;落下灰分散度较好 ,颗粒 ≤ 15 μm占5 0 .8% (以数量百分比计 ,下同 )、≤ 30 μm占2 6 .4%、>30 μm占 2 2 .8% ;成本相对较低廉 ,较经验配方节省约 10 %。结论 :该烟雾剂评价指标客观确切 ,灵敏度高 ,经济 ,简单易行 ,符合烟雾剂技术指标和实际应用要求 ,在此筛选标准下配制的灭蟑烟雾剂 ,发烟效果良好 ,配制简便 ,使用方便、经济 ,值得推广
Objective: To discuss the evaluation index and the optimal formulation of the smoking effect of ignition cockroach aerosol. Methods: According to the technical index of pilot cockroach cockroach aerosol and simple and economic principle, the evaluation index of smoking cockroach effect was deduced, and the optimum formula of tobacco smoke was screened by orthogonal design. Results: In order to ignite the ignition easy degree, with or without fire, with or without jetting, the average smoke time (s / 10. 0 g), the number of ash particles falling (/0.2mm × 0.2mm) and its distribution Uniformity (particle distribution coefficient of variation expressed), etc. as the evaluation index of smoking effect, consider the weight of each evaluation index; follow the orthogonal design principle 〔1〕, inferred the optimal formulation of smoke. The aerosol prepared by the optimal formula is easy to ignite with igniter, no open flame and smoky, with suitable speed (about 30 ~ 50s / 10g) Particles ≤ 15 μm accounted for 58.0% (in percentage by number, the same below), ≤ 30 μm accounted for 26.4%,> 30 μm accounted for 22.8%; the cost was relatively low, which was less than the empirical formula 10%. Conclusion: The aerosol evaluation objective is objective and accurate, high sensitivity, economic, simple and easy, in line with the technical indicators and practical application requirements of aerosol agent. The cockroach aerosol formulated under this screening standard has good smoking effect, simple preparation, Convenient, economical and worth promoting
