气溶胶灭火剂的配方及优化设计的研究

文章为了研究气溶胶灭火剂在工程应用中的灭火能力及所遇到的腐蚀问题,采用对比实验方法对K型和S型的气溶胶灭火剂的配方进行了研究。主要选择了以锶盐为主、钾盐为辅的氧化剂,设计并优化了几种配方。结果表明:从灭火效能、喷射时间、Cu板颜色变化等性能参数可以看出,当Sr(NO3)2与KNO3的比值在1.4～5.0范围内效果最好,灭火效能为95 g/m3,喷射时间为42 s,且Cu板没有明显地变绿,既保证了气溶胶的灭火能力,又较好地解决了腐蚀性的问题。

Research on the Formulation of Aerogel Extinguisher and the Optimization Design

In order to study the fire extinguishing capacity and the corrosion problem of the fire extinguishing aerosols in engineering application, experimental comparison for the formulation of the fire extinguishing aerosols between K type and S type was carried out in this paper. Taking strontium salt as the main oxidant and potassium salt as the supplement, several formulations were designed and optimized. From the results of the extinguishing concentration, spray time, Cu beard color change and other performance parameters, it can be seen that the best performance is obtained when the ratio of Sr（ NO3 ） 2 to KNO3 is 1.4 ： 5.0. Its fire extinguishing efficiency is 95 g/m3, spray time is 42 s, and Cu board has no obvious turned green, which not only ensures the aerosol extinguishing ability, but also provides a good way to solve the corrosion problem.
