摘要：

This work explores the feasibility of using chitosan (CS)-sodium alginate (SA) crosslinking gel to reinforce dry water (DW) composites. The stability and fire extinguishing efficiency of the DW powder are investigated. Compared to ordinary DW material, water loss rate of the modified DW composite is decreased, and its pressure resistance and stability are significantly increased. Moreover, it possesses higher fire extinguishing efficiency than conventional dry powder. Fire extinguishing mechanism and gel formation mechanism are proposed. The improvement in stability has great significance for the storage and transportation of DW materials. These results demonstrate the ability to create a fully green and renewable crosslinking gel capable of endowing high stability to DW material. This work provides a novel solution to improve the stability of DW materials, which will have great application prospect in fire suppression of some flammable hazardous chemicals.
