Analysis of the Cause of the Self-explosion of the Aluminum-panel Metal Curtain Wall-WJW Aluminum Supplier Aluminum

The poor quality of the glass itself is one of the reasons for the self -explosion of the glass, such as the flatness difference, uneven thickness, air bubble residue in the glass, etc. The doors and windows are composed of the panel and support structure system (supporting device and support system), and the main structure of the main body structure Compared with a certain displacement or deformation ability, and does not bear the role of the main structure. Under the irradiation of sunshine and uneven heat, doors and windows curtain walls will cause self -explosion.

When artificially cut glass, the edge of the cut glass must be lubricated and straight, and there are disadvantages such as collapse, teeth, and collapse. In order to reduce hard contact, the lower end of the glass cannot fall directly on the aluminum alloy border, otherwise the glass will easily explode under thermal expansion. There should be an elastic fixed pad under the glass, placed separately on the edge of the glass separately, at least two pads, the number of pads should be dependent according to the width of the glass. Make the glass in elastic contact under the aluminum frame. The glass can be freely expanded when the glass is hot and contracted, and the self -explosion can be reduced. At the same time, the glass must be sealed with elastic data. The gap around the glass and the aluminum frame should be left with a gap of about 47mm. Do not contact directly, and the gaps around are even. Glass perimeter and aluminum frames are sealed with elastic glass sealing, and the effect is better than the hard glue band inlaid with the gap between the inside and outside of the glass edge and the gap between the aluminum frame and the glass edge. In fact, many large -scale glass is embedded too tightly because the hard tape was used around the glass, and the glass exploded by itself because of thermal stress.

Inlaid glass aluminum frames cannot guarantee how much accuracy is. The aluminum frames are unevenly distorted, bending and deformation, and glass tortuous, which can easily cause thermal stress to explode. Installing glass must be strictly reached to construction standards.

The choice of glass thickness is very important. It must not only consider wind load, but also consider thermal stress. The building curtain wall is composed of a support structure system and panel. Compared with the main structure, it can have a certain displacement ability, and the external protective structure or decorative structure of the main structure does not share the main structure. The curtain wall consists of a structural frame and inlaid plate, which does not bear the load and role of the main structure. If the glass area is large, the thickness is small, the glass is resistant to twists and the heat resistance, so it is easy to explode by itself. The choice of glass thickness of the glass curtain wall must be calculated, and the glass force in the same area of low -level and high -rise is very different. In particular, the thermal expansion coefficient of coating glass is much longer than a single glass, and the thermal stress is more obvious. Some manufacturers and designers do not consider thermal stress in the calculation of glass, causing the glass to explode. The thickness of the thickness and length and width ratio of individual coating glass is related to the maximum area. Some coating glass manufacturers give a
