Why is the curtain wall glass so easy to blast?

Why is the curtain wall glass so easy to blast? Hot summer weather and high temperatures, coupled with extreme weather such as typhoons and heavy rains, can easily cause the glass curtain wall to burst. In addition to glass breakage caused by impurity nickel sulfide and glass breakage caused by thermal stress, we also analyzed it based on the cause of thermal stress. The thermal stress of glass rupture caused by thermal stress is an important reason for the rupture of glass curtain wall. There are many reasons why the glass curtain wall is heated, but the main heat source is sunlight. When the sun shines on the surface of the glass curtain wall, the glass will expand due to heat. If the glass is uniformly heated, the edges of the glass and the center of the glass will expand uniformly at the same time. However, if the edges of the glass and the glass are heated unevenly, tensile stress will be generated in the glass. When cracks or small cracks appear on the edge of the glass, these defects are easily affected by thermal stress. As the temperature difference increases, thermal stress causes a gradual increase in cracks, which eventually leads to glass breakage. Both winter and summer are the seasons when the glass curtain wall explodes, while the south is mainly in summer. If the outdoor temperature is very high, the indoor air conditioner is very low, and some curtains are folded together, it is easy to make the outside of the glass become unevenly heated and cold, which may cause self-explosion.
