玻璃幕墙使城市的高层建筑外观光彩夺目,美丽无比。但是幕墙玻璃如粘结不牢,就会对街道上的行人及车辆构成威胁。所以幕墙玻璃用的硅酮结构密封胶(以下简称结构胶)的质量关系着人民生命财产的安全。 一、我国玻璃幕墙发展迅速,结构胶用量骤增 玻璃幕墙是悬挂在主体建筑结构上的外墙围护构件,分层承载安装,靠结构胶粘结力使玻璃附着在外墙铝合金结构框架上。玻璃幕墙是集建筑功能和建筑艺术于一体的新型墙体,它除了满足建筑物的围护作用和要求(防止风雨、保持温度、控制噪音和污染)外,也使建筑物富有光质感。因此玻璃幕墙在很短的时间内便风
Glass curtain walls make the city’s high-rise buildings look dazzling and beautiful. However, if the curtain wall glass is not firmly bonded, it will pose a threat to pedestrians and vehicles on the street. Therefore, the quality of the silicone structural sealant used for curtain wall glass (hereinafter referred to as structural adhesive) is related to the safety of people’s lives and property. 1. The rapid development of glass curtain walls in China and the sudden increase in the amount of structural glue The glass curtain wall is an external wall retaining member suspended on the main building structure. It is installed in layers, and the glass is attached to the outer wall aluminum alloy structural frame by the adhesive force of the structural adhesive. . Glass curtain wall is a new type of wall that integrates building function and architectural art. It not only meets the building’s enclosing function and requirements (prevents wind and rain, maintains temperature, controls noise and pollution), but also makes buildings rich in light texture. Therefore, the glass curtain walls wind in a short time
