摘要
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. © 2021, Chemical Industry Press Co., Ltd.. All rights reserved.
