建筑幕墙上玻璃风化的分析与对策

Analysis and countermeasures of glass weathering on building curtain wall

玻璃风化是由玻璃原料配方、生产工艺、构造措施及使用环境等因素引起的,严重影响建筑外观效果,目前除了更换玻璃别无他法,且不能从根源上彻底消除,分析建筑幕墙玻璃风化的案例和工艺,研究幕墙层间阴影盒设计与玻璃风化的关联和机理,可为材料选型、构造设计、生产加工、现场安装等提供参考。

Glass weathering is caused by glass raw material formula,production technology,construction measures and useful environment,etc.It seriously affects the appearance of the building.At present,there is no other way except to replace the glass,and it cannot be completely eliminated from the root.This paper analyzes the cases and technology of glass weathering of building curtain wall,and studies the relationship and mechanism between shadow box design between curtain wall layers and glass weathering,so as to provide reference for material selection,structure design,production and processing,and site installation.
