1. The poor quality of the glass itself is one of the causes of glass self-explosion, such as poor flatness of the glass, uneven thickness, and slag inclusions in the glass. Under the sun, the thermal effect is not uniform, resulting in cracking and self-explosion.

2. When manually cutting the glass, the edge of the cut glass must be straight and smooth, and defects such as chipping, flank, and chipping are not allowed. It is necessary to ensure that the periphery of the glass is not used in the state of disability, otherwise the self-explosion point is easily generated at the edge of the glass.
3. In order to reduce the hard-to-hard contact when the glass is installed, the lower end of the glass cannot fall directly on the aluminum alloy frame, otherwise the glass is easily self-explosive due to thermal expansion. There should be elastic fixed blocks under the glass. The placement position is generally 1/4 of the edge of the glass. At least two spacers should be placed. The number of spacers should be determined by the width of the glass. The underside of the glass is in elastic contact with the aluminum frame, and the glass can be freely stretched and contracted when it is inflated and contracted, thereby reducing self-explosion. At the same time, the periphery of the glass should be sealed with a material with good elasticity. The periphery of the glass and the aluminum frame should have a gap of about 4 to 7 mm, which is not in direct contact, and the peripheral gap is uniform. The glass perimeter and the aluminum frame are sealed with a glass sealant with good elasticity, which is better than the hard rubber strip inlay between the inner and outer sides of the glass edge and the aluminum frame. In reality, many large-area glass are too tightly packed with hard rubber strips around the edges of the glass, and the glass blew itself due to thermal stress.
4. The aluminum frame with glass inlay can not guarantee the geometric precision. The aluminum frame is twisted unevenly, bent and deformed, and the glass is bent and stressed, which is easy to cause thermal stress to self-explosion. The installation standard must be strictly implemented in the installation of glass.
5. The choice of glass thickness is very important, considering not only the wind load but also the thermal stress. If the glass area is large and the thickness is small, the glass is resistant to bending and thermal stress, and is easily bleed. The selection of the thickness of the glass curtain wall glass must be calculated. The stress on the glass in the same area of ​​the lower layer and the upper layer is very different. In particular, the thermal expansion coefficient of coated glass is much larger than that of ordinary glass, and thermal stress is more obvious. Some manufacturers and designers do not consider thermal stress in the glass calculation to cause self-explosion of the glass. Generally, the relationship between the thickness, aspect ratio and maximum area of ​​coated glass, some coated glass manufacturers, gives a relationship ratio, which is only for reference. Due to the different use of glass, the area should be adjusted, and the calculation should be taken as the standard. Glass thickness, aspect ratio, glass maximum area, glass thickness, aspect ratio, glass maximum area: 6mm1:3 or less, 2.5m2 or less, 8mm1:3 or less, 4m2 or less, more or less, causing cracking of the glass curtain wall If you want your glass curtain wall to be safe, you have to pay attention to any of them.
