(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.

公司研制了一种用于法兰连接的弹性密封垫片，其端面涂布了厌氧胶，该垫片由支承底片和由刚性弹性体材料制备的垫圈构成，其两面是由较柔软的材料制成的环形增强条，旨在防止硅烷改性聚氨酯密封胶被挤出。

厌氧硅烷改性聚氨酯密封胶在汽车工业、农业、电子工业、机器制造业、仪表制造业，特别是在高真空、高压、高温差条件下使用的设备上获得了广泛应用，其密封质量可靠，节省材料和劳动力，成型过程的机械化、自动化程度高。

公司生产的双组份硅烷改性聚氨酯密封胶，适用于密封面间隙尺寸可变的可卸式固定连接的密封。

公司生产的单组份固化型硅烷改性聚氨酯密封胶，硅烷改性聚氨酯密封胶用红外线固化-25s后即不再流动，然后靠湿气固化。变成具有弹性的类橡胶状物。

总之，硅烷改性聚氨酯密封胶的密封性能，不仅取决于其本身的性能，而且还取决于一整套的结构和工艺等综合因素的影响:连接件的工作条件(温度、压力，密封介质的性能，工作寿命，是否存在振动、变形，冲击负荷作用等);整体连接或配件的结构(构形，几何尺寸，配合精度，表面特性等);制造和装配的工艺性能(表面处理方法及特性，加工精度，与最佳工艺条件的匹配，密封顺序、与计算温度和压力相对应的使用参数，检验周期等);在密封区内，硅烷改性聚氨酯密封胶的化学反应过程(一定结构胶膜的形成，因变形引起的几何形状的变化等)。

因此，只有根据被密封面的密封条件，密封结构、环境条件的要求，正确地选择硅烷改性聚氨酯密封胶的类型、品牌和密封工艺才能获得稳定、可靠、使用寿命长的密封效果。www.sdyuantai.com
