(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.

再粘结试片制备方法如下:切取既有的聚氨酯密封胶，用刀具将其切割成表4中6LJ06B号所述宽厚尺寸，长为a8的试样，用聚氨酯密封胶(最大强度口重新粘结制得型片，聚氨酯密封胶再粘结层总厚度小于G4必要时可采用底涂增强粘结面的粘结性能，如图G所示。建筑用聚氨酯密封胶中规定，在标准试验条件温度(BMB，相对湿度下养护B(拉伸粘结性实验采用万能拉力试验机进行测试。结果与讨论不同宽口厚尺寸对聚氨酯密封胶拉伸粘结性的影响;宽度尺寸变化对聚氨酯密封胶性能的影响取养护P的试片，将同尺寸同条件下的试片测试结果取平均值，处理结果如表M图BflM所示。

从图B和图M可以看出，与其他M组相比，P组试片宽度和厚度尺寸较大，最大强度及最大强度伸长率明显偏小，这说明该宽度和厚度是不合适的，也不符合聚氨酯密封胶胶缝设计要求口在CM组中，厚度不变时，聚氨酯密封胶试片最大强度随宽度变化有一些变化，但变化不明显，其中a组极差最大，为但厚度不变时，聚氨酯密封胶试片最大强度伸长率随宽度变化较大，其中a组极差最大。厚度尺寸变化对聚氨酯密封胶性能的影响取养护%的试片，将同尺寸同条件下的试片测试结果取平均值，处理结果如表翎图。http://www.sdyuantai.com/
