摘　　要：根据泡沫降尘技术对泡沫降尘剂的要求,采用泡沫扫描仪和沉降方法,研究了4种活性试剂在不同浓度时的起泡性能、润湿性能和泡沫稳定性。试验结果表明:L3的起泡性能最好,SD12的润湿性最优,AP的半衰期最短。综合考虑降尘泡沫的性能要求,SD12最适宜用作泡沫降尘剂,或进行复配以提高其性能,泡沫降尘剂的最优添加浓度为0.5%。According to the requirements for foaming agents used in foam dust control technology,foamscan and settling methods were taken to study the foaming and wetting properties and foam stability of four kinds of surfactants at different concentrations. The experimental results show that the foaming performance of L3 is the best, the wetting property of SD12 is optimal, and the foam half-life time of AP is the shortest. Considering the requirements for foam properties, SD12 is the most suitable surfactant used as foaming agent for dust control, or improving its properties through compound method.The optimal adding concentration of foaming agent is 0.5%.
