摘要： 新型干水灭火剂具有灭火高效、清洁环保等特点，集合了水基灭火剂和干粉灭火剂的优势，为应对随社会发展不断出现的新火灾场景提供了更多的选择。通过对比不同固液配比制备的硫酸铵干水粉体的粒径分布和流动性，发现在转速3 000 r/min，搅拌时间6 min 时，1∶13 的固液配比制备的干水粉体更适合用作灭火剂。然后进行了不同释放压力工况下的灭火实验，通过对比9 组实验的实验现象和实验数据，发现在0.6～0.7 MPa的充装压力下，其灭火效率最佳。

Abstract: The new- type dry-water fire extinguishing agent has the characteristics of high efficiency, cheap and environmental protection. It combines the advantages of aqueous fire extinguishing agent and dry powder fire extinguishing agent. It will provide more choices for dealing with the new fire scenarios emerging with the development of society. By comparing the particle size distribution and fluidity of modified ammonium sulfatedry- water powder prepared by different solid-liquid ratio, it is found that the dry-water powder prepared with 1∶13 solid-liquid ratio can meet the requirements of fire extinguishing agent well at the speed of 3 000 r/min and stirring time of 6 min. Then, the fire extinguishing experiments under different release pressure conditions were carried out. By comparing the experimental phenomena and experimental data of nine groups of experiments, it is found that the best fire extinguishing efficiency is obtained under the filling pressure of 0.6～0.7 MPa.
