建筑的外装饰大量采用干挂天然花岗岩,此类石材沙眼和裂隙比较丰富,吸水率较大,按规范要求外墙石材在出厂时都已做到六面防护处理,在表面形成避水层,可在实际应用中,经过处理的石材表面还会出现难以清除的水斑污染。文章阐述了如何从多角度预防外幕墙干挂石材遭遇结露水的浸渗,最大程度防止花岗岩石材面层水斑污染的出现。
A large number of exterior decoration of the building with dry hanging natural granite, such travertine trachoma and fissures are abundant, greater water absorption, according to the specifications of the external wall stone at the factory have done six protection treatment, the formation of the surface of the water-resistant layer, In practical applications, the treated stone surface will appear difficult to remove water stains pollution. This article elaborates how to prevent the external wall dry-hanging stone from being exposed to dew water infiltration from various angles and to prevent the occurrence of water spot pollution on the surface of granite stone to the greatest extent.
