When the public debate over the safety of glass curtain wall gradually subsided, the industry has not stopped discussing the safety and energy-saving performance of glass curtain wall.
At the Peak Forum on Safety and Energy Conservation of Building Glass sponsored by China Building Glass and Industrial Glass Association and co-sponsored by China Huihua Glass Co.,Limited, some experts said that the self-explosion of tempered glass could not be avoided, but the self-explosion rate of glass could be reduced to one thousandth by using new products such as ultra-white glass, which fundamentally solved the problem of self-explosion of glass curtain wall.
Professor Zhao Xi'an, an expert of the Aluminum Door, Window and Curtain Wall Committee of China Building Metal Structure Association, said that the probability of glass curtain wall self-explosion did not increase significantly, and there was no "hidden danger of high-rise building safety" problem, so the society need not worry.
The self-explosion of tempered glass caused by impurities in raw materials and production is an unavoidable problem both at home and abroad. At the same time, from the perspective of such a huge area of glass curtain wall in China, the safety accidents of glass curtain wall are still rare, not to mention the fatal accidents.
hhglass, an expert of China Building Glass and Industrial Glass Association and director of engineering glass technology of Nanbo Group, pointed out that although the self-explosion of tempered glass can not be avoided, the self-explosion rate of homogeneous glass and ultra-white glass produced by special technology can be greatly reduced. "Normal white glass has a self-explosion rate of 3 -5. Ultra-white glass is a kind of highly transparent low iron glass. Because of less impurities, the self-explosion rate can be reduced to less than 0.1 and the delivery time is short, and the production cost is lower than homogeneous tempered glass."
An Overview of Shanghai Lujiazui
Glass curtain wall is the best choice for the outer envelope of super high-rise buildings. Glass curtain wall has the characteristics of light weight, high strength and beautiful appearance. Glass curtain wall is used in super high-rise buildings, especially those over 400 meters. Ultra white glass is the best choice for glass curtain wall panel. Many super high-rise buildings, including Shanghai Central District, have used ultra white glass.
