摘要/Abstract

摘要： 为定量分析爆炸冲击波载荷下防爆膜对中空玻璃的防护效果,对贴膜和未贴膜的中空玻璃进行爆炸对比试验。通过调整爆距和药量获得不同爆炸载荷下玻璃的破碎状态,并根据压力传感器测量的爆炸冲击波超压值,得到贴膜与未贴膜中空玻璃破碎的临界超压值。结果表明:中空玻璃粘贴防爆膜能有效降低贴膜一侧玻璃碎片所造成的伤害,并能显著提高中空玻璃破碎的临界超压值;背爆面贴膜的中空玻璃防爆性能大于迎爆面贴膜的防爆性能;在玻璃上直接粘贴防爆膜不能完全发挥防爆膜的防护效果。

Abstract: In order to quantitatively analyze protection effects of explosion-proof film on insulating glass under explosion shock wave load, comparative experiments of insulating glass with and without film were carried out. Broken states of glass under different explosive loads were obtained by adjusting burst distance and explosive charge, and threshold overpressure values of broken insulating glass with and without film were obtained according to overpressure values of explosion shock wave measured with pressure sensor. The results show that explosion-proof film can effectively reduce damage to glass side which has film on it and increase threshold overpressure value of glass fragmentation. Explosion-proof capability of glass with film back to explosion wave front is greater than that with film face to the front, and it cannot give full play to its protective effects if explosion-proof film is pasted on glass directly.

Key words: explosion-proof film, insulating glass, glass fragment, threshold overpressure value, explosion-proof capability
