Research progress in preparation and application of hydrogel fire extinguishing agent
This article provides a comprehensive review of the research progress on hydrogel fire extinguis-hing agent from the aspects of synthesis and application scenarios both domestically and internationally.The extinguishing mechanism of hydrogel fire extinguishing agent is introduced.Based on their main syn-thesis materials,hydrogel fire extinguishing agent can be classified into starch-based,cellulose-based,chi-tosan-based,organic synthetic polymer-based,and other natural substance-derived categories,each of which is elaborated upon in detail.Furthermore,the feasibility of applying these fire extinguishing agent in various fire scenarios,including coal mine fires,liquid fires,forest fires,building fires,and lithium battery fires,is analyzed.The future development trends of hydrogel fire extinguishing agent are outlined,provi-ding valuable insights for subsequent research and applications.
