摘要/Abstract

摘要：

干水（dry water）是微水滴颗粒被纳米级疏水性二氧化硅颗粒包覆层封装形成的、整体呈固体粉末状的粉体材料，其颗粒内含水量可高达98%，内部水分可以通过高温蒸发和外力挤压作用释放出来，是很有潜力的特种灭火新型材料。干水灭火剂的核心是功能性化学灭火组分，本文设计并制备了包覆不同功能性化学灭火组分的系列干水灭火剂，并测定表征了所制备干水灭火剂的粒径分布、流动性与保水性，研究了不同功能性化学灭火组分对干水灭火剂储运性能的影响。结果表明，不同功能性化学灭火组分的加入能够在一定程度上提高干水材料颗粒的流动性和保水性，其中磷酸二氢铵干水的流动性最优，氯化钠干水的保水效果最好。研究对干水灭火剂的制备、储运与使用具有重要意义。

Abstract:

Dry water is a powder material formed by encapsulating micro-water droplets by a coating layer of nano-level hydrophobic silica particles. The overall water content in the particles can be as high as 98%, and the internal water can pass through. High-temperature evaporation and external force squeeze released, which is a new type of special fire-fighting material with great potential. The core of dry water fire extinguishing agent is functional chemical fire extinguishing components. In this paper, a series of dry water fire extinguishing agents coated with functional chemical fire extinguishing components are designed and prepared, and the particle size distribution, fluidity and water retention of the agent are measured and characterized, Studied the effect of different functional chemical fire extinguishing components on the storage and transportation performance of dry water fire extinguishing agent. The results show that the different functional chemical fire extinguishing components can improve the fluidity and water retention of dry water material particles to a certain extent. Among them, ADP-DW has the best fluidity and NaCl-DW has the best water retention effect. The research is of great significance to the preparation, storage, transportation and use of dry water fire extinguishing agents.

Key words: dry water, fire extinguishing component, fluidity, water retention
