森林防火避火罩的研制

Development of Forest Fire Shelters

森林防火避火罩是由金属铝箔与玻璃纤维织物经黏合剂复合的材料制成。采用稳定度高、受热面小,冷却性能好的三角形结构设计,具有反热辐射、耐高温等技术性能。当扑火人员被林火围困时,进入避火罩中能防止火场高温辐射对人体的伤害,同时也起到隔绝热气流和烟尘的作用,并能呼吸到清洁的空气,保护使用者的人身安全。

Forest fire shelters are composite materials made of metal foil and glass fabrics by means of adhesive. A triangular structural design featuring high stability, small heating surface and excellent cooling performance is adopted to allow the shelters to have such technical performance of anti- thermal radiation and high-temperature resistance. When forest firefighters are trapped in a forest fire ,the fire shelters can prevent the high temperature radiation at the fire scene from causing damage to human bodies, and at the same time they can isolate hot air stream and smoke and allow firefighters to breath fresh air, ensuring their personal safety.
