(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.

防水和粘结施工等方面，本文就其在混股土防水谁工中的应用进行总结云以期为令后类似工聚氨酯密封胶是一种新型粘接材料，具有良好的耐候性、水密、气密性、防水效果好等诸多优点，广泛应用于沉降缝和变形缝的密封、防水施工，以及金属或玻璃的气密、水密嘟由密粘结施工等方面。

施工准备叶基层修整、清扫--1填塞背衬材料卜卜贝占防污条一卜涂底涂料，混料弓装注胶枪并嵌填一够平压光升除防污条、清理缝边叶养护(衬做保护层)。

聚氨酯密封胶由A组份(白色基膏)和日组份(黑色硫化膏)组成，其掺加比例为A:B二100:8-100:12，气温高时适当减少B组份用量，反之增加用量，但不宜加量过多，以防固化过快而影响粘结弓虽度，甚至反硫化。配制好的聚氨酯密封胶活险期一般为1-8小时。

应在底涂料涂刷后的千燥期内进行，了影交过早会因等待底涂料干燥而缩短聚氨酯密封胶的有效使用期，甚至固化失效而造成浪费;过晚会拖延工时。;翩交宜采用机械搅拌，将A, B组份倒入搅拌桶内，插入电动搅拌器低速、自上而下进行搅拌。每搅拌2-3min停一下，用刮刀将粘附在底、壁上的材料刮至)混合料中重新搅拌直至均匀。交采用人工弓昆合时，可将A.B两组份倒在玻璃板上，用批刀来回批抹直至均匀。搅拌均匀的混合料应颜色一致、无色差，检查方法:用腻子刀将混合料在平面上刮薄，如无不同颜色的斑点或条纹，即拌匀。

将中间带有出胶孔和推力杆的压胶盘里入搅拌好的胶面上。取下枪管前、后螺盖，枪口对润到交盘出胶口，手握枪管和推力杆，用力下压，将胶注入枪管至灌满，安装枪管前、后螺盖，完成装枪。www.sdyuantai.com
