(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.

通过硅烷改性聚氨酯密封胶在外窗结构和中空玻璃中的应用研究以及对外窗节能效果的分析，说明选用合适的硅烷改性聚氨酯密封胶可以加强外窗结构的气密性。提高中空玻璃的质量，从而实现外窗的节能。

建筑节能是落实我国节能减排政策的重要内容之一，而门窗节能则是提高我国建筑节能的关键所在。加强外窗结构的密封性。采用节能的中空玻璃，是实现外窗节能的重要技术途径。

外窗是通过玻璃传导。辐射热量与透过存在的缝隙对流热量而产生热损失的，节能则可以从窗型。玻璃。窗框三个方面入手采取措施，通过对热的对流。传导和辐射这)种热交换进行有效的阻断达到节能的目的。这其中硅烷改性聚氨酯密封胶起着十分重要的作用，其在建筑外窗节能中的应用主要有两个方面:一是对外窗进行密封处理;二是用于中空玻璃。

民用建筑热工设计规范。(gYF/(DPfII)规定犷建筑物外部窗户的气密性等级不应低于现行国家标准建筑外窗空气渗透性能分级及其检测方法。规定的III级水平，这相当于要求窗户每米缝长的空气渗透量。保证外窗结构密封性的关键是选择合适的密封材料，一般可从以下两个方面加以考虑。

铝合金门窗验收标准要求:门窗关闭后各配合处无缝隙。不透气。不透光，密封面上的密封条处于压缩状态。这就要求所使用的硅烷改性聚氨酯密封胶条具有较高的复原性和位移补偿能力。所谓复原性是指受外界应力变形后可恢复原状的程度;位移补偿能力是指随接头的变形而变形，却不会从基材脱离的能力。选用的硅烷改性聚氨酯密封胶条须能适应接缝受到压力或拉力时所产生的位移以及基材受热时的膨胀和受冷时的收缩。

合适的硅烷改性聚氨酯密封胶条是外窗气密性和水密性的保证，较常用的是硫化橡胶类硅烷改性聚氨酯密封胶条三元乙丙橡胶等和热塑性弹性体类硅烷改性聚氨酯密封胶条热塑性硫化胶。聚氨醋热塑性弹性体。其中iuJl和ruw等耐候性好的胶条是比较理想的处理外窗密封用的胶条。http://www.sdyuantai.com/
