(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.

节能建筑是建设节约型社会的需要。目前我国建筑能源消费已占总能源的27 %，既有的400亿平方米建筑基本是高能耗建筑，48%的建筑在冬冷夏热地区，保温隔热水平低，外墙散热量为国外1. 5一2. 2倍，冷风渗透量是国外的3一6倍。窗在房屋建筑能耗中比例最大，热损失占总量的40%。根据我国建筑节能法规要求，节能的一个重要措施是用中空玻璃逐步成为窗用玻璃的主体。目前我国中空玻璃产量约2 000万平方米(15年前为50万平方米)，主要用于公用工程和商用建筑。按照我国每年房屋门窗的新建增长量1.5亿平方米推测，2015年我国中空玻璃产量(包括建筑、车辆、冷藏设备等用量)将达到9 000万平方米，如果包括用于冷风渗透密封，包括硅酮型产品在内相关聚氨酯密封胶用量将增长5倍以上。由于建筑结构的变化和新型建材的应用，建筑接缝位移量显得更加突出，接缝不密封或密封失当造成渗漏已引起人们的关注，据统计近年来建筑工程质量投诉50%涉及渗漏，其中外墙渗漏约占40%，有人称“十缝九漏”可能过分，但建筑接缝必须用耐候性聚氨酯密封胶嵌填密封，变形缝、伸缩缝必须用位移能力优良的聚氨酯密封胶已逐渐成为业内的共识，将为聚氨酯聚氨酯密封胶的发展提供更大的市场。

具有重要地位的钢结构建筑突出了密封防腐蚀的要求。以彩色钢板建筑屋面和外墙为例，为保证建筑使用寿命和功能质量，规范规定接缝防水、防腐密封用聚氨酯密封胶每平方米消耗约o. s公斤。按照目前实用面积推算，总用胶量应在2万吨以上，但实际用量尚未达到设计水平。聚氨酯聚氨酯密封胶具有开发这一市场的前景。www.sdyuantai.com
