(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.

由于不同化学结构的聚氨酯密封胶老化程度具有差异性，所以PU聚氨酯密封胶老化到一定时间后，拉伸模量就会到达最大值，其余种类的聚氨酯密封胶达到一定时间后，拉伸模量也会出现最大值，这与内部结果的交联密度有关。聚氨酯密封胶在工程应用中的对比研究。

将位于上海某海港基地的装配式建筑用作研发中心;这座建筑是以绿色节能的方式建造的，共建成3座建筑示范楼。将PU聚氨酯密封胶、PC910聚氨酯密封胶、SMP651聚氨酯密封胶、SMP652聚氨酯密封胶4种聚氨酯密封胶分别应用到装配式建筑外墙保温板接缝中，根据不同类型聚氨酯密封胶的内部结构，对聚氨酯密封胶在接缝中的性能开展长期试验及观察研究。

聚氨酯密封胶在接缝中的施工

设定在装配式建筑外墙保温板外侧水平、竖直缝中进行聚氨酯密封胶防水封堵操作，令外墙保温板的侧壁保持整洁、干燥。在施工前检查所需材料性能、质量及配合比，使外墙保温板接缝能够牢固粘接，不容许存有缺陷;

令装配式建筑外墙的外侧竖缝与水平线之间的注胶宽度、厚度符合设定接缝条件，待外墙保温板接缝固定后校核，再利用聚氨酯密封胶对接缝嵌填。主要流程为:放人泡沫棒，最后再向缝隙中打胶。在施工期间，外墙的防水空腔不能填补，同时聚氨酯密封胶在注胶时要保证表明是光滑的，不能出现裂缝。那么泡沫棒、聚氨酯密封胶注胶、修胶过程如图1所示。http://www.sdyuantai.com/
