As a unique design in modern curtain wall building, glass curtain wall not only embodies the best combination of architecture and aesthetic structure design, but also perfectly embodies the various functions of glass. Such as the transparency of the glass curtain wall, through the glass line of sight to achieve the best, the field of vision to achieve the largest, so that the building internal and external environment is interlinked, and so on. The glass curtain wall has good technical performance, the glass curtain wall support components are processed carefully, the surface is smooth and has a good sense of technology and art, which can adapt to any geometric shape, produce rich changes in the building shape. It can fully reflect the imagination and creativity of designers. At present, one of the biggest highlights of the use of glass curtain wall is the use of various energy-saving curtain wall glass; it greatly reduces the energy consumption of buildings. However, in the past period of time, many architectural projects have been plagued by the glass curtain wall, some design, material selection, unreasonable construction of the glass curtain wall, because of its glass broken, glass falling, water leakage and other problems, the community has been widely concerned.
Glass curtain wall due to a variety of unreasonable application, easy to cause a lot of problems, such as tempered glass self-implosion rate is too high, structural adhesive failure, poor fire performance, glass curtain wall support structure failure and glass curtain wall fixed device failure and so on.
There are many reasons for glass breakage. First of all, the glass breakage caused by impurity nickel sulfide and thermal stress is analyzed and demonstrated.
A glass burst caused by an impurity nickel sulfide
Nickel sulfide is an inevitable harmful impurity in the glass production process. Nickel sulfide itself has no damage to the glass, but when the glass of curtain wall containing nickel sulfide is installed, due to the rise of external temperature, resulting in small changes in the volume of nickel sulfide, resulting in small cracks in the glass. These cracks through the tempered glass tension layer after the release of internal energy, resulting in glass breakage.
The solution is to start from the source. curtain wall suppliers should monitor the whole process of glass manufacturing and minimize the contact between nickel-containing materials and glass raw materials. Secondly, for the curtain wall glass after the installation of monitoring, there are foreign photographic detection of nickel sulfide impurities in the presence of technology.
