(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

       介紹了單元式玻璃幕墻、框架式玻璃幕墻、石材幕墻以及鋁板幕墻工程中丁基防水嵌縫膠的設計和應用特點,對幕墻工程中中空玻璃粘結尺寸過小、設計用膠執行標準不當、中空玻璃內滲油、丁基防水嵌縫膠老化等用膠常見問題進行了分析,并提出了相應的處理方法。

       幕墻素有“建筑衣服”之稱,通過幕墻,我們把建筑之美更具體地展現在世人面前。作為建筑外圍護結構,幕墻為建筑分隔了室內外空間,并從初始的避風擋雨發展成為一道滿足室內舒適性的構造層次。

       丁基防水嵌縫膠是建筑幕墻發展中不可或缺的材料,它是連接幕墻面材各個板塊的橋梁,也是保證幕墻具有良好氣密性和水密性的法寶。

       幕墻種類眾多,現選取單元式玻璃幕墻、框架式玻璃幕墻、石材幕墻與鋁板幕墻來介紹丁基防水嵌縫膠的應用。

       單元式玻璃幕墻解決漏水問題,宜采用“等壓原理”。幕墻產生漏水現象,必須有3個條件:一是有水存在,如下雨或清洗幕墻用水;二是存在水可通過的通道;三是存在能使水運動的動力(有6種—重力、動量、表面張力、毛細現象、氣流和壓力差)。

       壓力差是造成大部分幕墻接縫漏水的主要原因,幕墻室外水分,不論是雨水或清洗幕墻用水,進人室內,除了必須要有破口或裂縫存在外,還必須要求室外壓力比室內壓力大。如果室內壓力等于室外壓力,或者大于室外壓力,即使有破口或裂縫存在,水分也不會進人室內。一般傳統的防水方式是設法在接縫處減少可能發生的開口,如用各種丁基防水嵌縫膠對接縫進行密封堵塞。為單元式幕墻橫向防水節點示意圖,圖2為單元式幕墻防水三維節點示意圖。http://www.www.sunsage.net/
