摘要

对三种尺寸的双层中空玻璃破裂行为进行研究,分析了迎火面和背火面玻璃重要测点的温度、裂纹形态及破裂时间等参数。得到迎火面玻璃温度与时间符合三次函数的走向,背火面玻璃温度与时间符合二次函数的走向。玻璃首次破裂时间随着玻璃面积的增大而减小。介绍了实验过程和相关步骤,得出相应结论,有助于了解双层中空玻璃的火灾属性。
        The fracture behavior of hollow glass with three dimensions was studied. The temperature, crack pattern and rupture time of the important measuring points in the fire face and the back fire face of the glass were analyzed. The temperature and time of the fire face were consistent with the direction of cubic function; the temperature and time of the back face were consistent with the direction of quadratic function. The first crack time of glass decreased with the increase of glass area. The experiment process and relevant steps were introduced,and the corresponding conclusions were obtained so as to help to understand the fire behavior of double glazing hollow glass.
