摘　　要：介绍茧覆惰化材料的抑爆原理以及抑爆性能测试平台的搭建。设计试验模拟危险化学品泄漏,通过喷洒一定配比的试验药剂,对比不同浓度的茧覆材料溶液对甲烷稀释吸收的情况,验证茧覆材料的抑爆性能。结果显示新型茧覆惰化材料包裹危险物质分子形成化学茧,降低空气中危险物质浓度,其抑爆能力优于普通水基灭火剂且远远优于纯水。The explosion-suppression principle and building ex- plosion-suppression performance platform were introduced. Hazardous of chemical leaking process was simulated. The ex- plosion-suppression performance of cocooning material was proved by adding different amount of cocooning material into water spray extinguishing system and testing the effect of ab- sorbing hazardous chemicals. Experiment results showed that cocooning material could reduce concentration of hazardous chemicals by wrapping hazardous chemicals to form chemical cocoons. The new cocooning material had excellent performance in explosion suppression, better than common water-based fire extinguishing agent and pure water.
