(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.

硅烷改性聚氨酯密封胶在装配式建筑外墙保温板接缝封胶完成后，要对封胶后的外墙面进行淋水、喷水操作，观察喷水后的墙面，检验墙面缝隙中是否有出现渗漏的情况。

基于以上操作，获取硅烷改性聚氨酯密封胶在装配式建筑中的效果对比，具体如表4所示。

根据表4硅烷改性聚氨酯密封胶应用效果对比结果，得知PC910硅烷改性聚氨酯密封胶与SMP651硅烷改性聚氨酯密封胶的应用性能最佳;而PU硅烷改性聚氨酯密封胶的应用性能最差，可以判断PC910硅烷改性聚氨酯密封胶与SMP651硅烷改性聚氨酯密封胶更适用于装配式建筑外墙保温板接缝密封下程。

由于硅烷改性聚氨酯密封胶的化学结构不同，导致硅烷改性聚氨酯密封胶的注胶结果差，针对这一问题，提出装配式建筑外墙保温板接缝用硅烷改性聚氨酯密封胶研究。该方法根据硅烷改性聚氨酯密封胶的粘接性及耐老化性能开展了测试分析，获取各个硅烷改性聚氨酯密封胶的性能结果，基于测试的硅烷改性聚氨酯密封胶性能结果将硅烷改性聚氨酯密封胶在实际建筑工程中应用，最终通过施工结果得出更适用于装配式建筑外墙保温板接缝密封工程的硅烷改性聚氨酯密封胶。

渠道衬砌u土裂缝的危害很大，影响到况凝土结构安全和通水运行的使用功能程实例，介绍了禾用双组分硅烷改性聚氨酯硅烷改性聚氨酯密封胶处理裂缝的施工工艺和技术要求，这次实践证明，这是一，缩短了结构的使用寿命。本文结合工种行之有效的裂缝处冶方法。

传统的密封材料耐候性差，易老化。或与材料结合变形不同步易脱落、使得工程耐久性不符合要求、加固使用周期变短。增加了维修成本。而有一些耐久的有机密封材料，在使用过程中会产生污染及毒害也不能满星工程需要。

双组分聚疏硅烷改性聚氨酯密封胶克服了传统密封材料的不足是一种国际、国内最领先的新型防水刊料。是建设部推广应用的新型建材。它外观细腻。是一种均匀的膏状物或粘稠物。也称双组分聚硫密封膏其以液态聚硫像胶为主要基料、添加多种化学助剂。经特殊高分子材料合成工艺制作而成，常温下能够自硫化交联聚合。主液态聚硫橡胶分子末端具有一H基、分子涟具有一55-键，固化主要以金属过氧物为卞。两个b分按给定的比例混合。常温卜能固化形成橡胶状弹性体。作为防水密封材料逐渐被泛应用于土木建筑工程、受到人们的青睐二它具有以下优点。http://www.sdyuantai.com/
