摘要： 设计并制备了包覆功能性化学灭火组分的系列干水灭火剂，研究了不同功能性化学灭火组分对干水灭火剂松密度和在高压下结构稳定性的影响。结果表明，干水灭火剂的松密度为0.348 0~0.437 3 g/mL；150 μm以下的干水灭火剂具有较好的耐压性能；不同灭火组分的加入对干水灭火剂颗粒的耐压性能没有明显影响，但凝胶剂的加入能够显著提高干水灭火剂的结构稳定性，使其在高压下保持原有稳定结构。研究结果对干水灭火剂的推广使用具有重要意义。

Abstract:

A series of dry water fire extinguishing agents coated with functional chemical fire extinguishing components are designed and prepared, and the effects of different functional chemical fire extinguishing components on the bulk density and structural stability of dry water fire extinguishing agents under high pressure are studied. The results show that the bulk density of dry water fire extinguishing agent is 0.348 0 ~ 0.437 3 g/mL; dry water fire extinguishing agent below 150 μm has better pressure resistance; the addition of different fire extinguishing components has no obvious influence on the pressure resistance, but the addition of gelling agent can significantly improve the structural stability of the dry water fire extinguishing agent, so that it can maintain the original stable structure under high pressure. The research results are of great significance to the promotion and use of dry water extinguishing agents.
