Abstract

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
