(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.

表示不同半径下的轴向压缩距离和径向位移之间的关系，可知开孔半径为3,5 mm时硅烷改性聚氨酯密封胶胶筒最先与内滑套接触，此时的轴向压缩距离分别为30.9,31.1mm，结合压缩行程曲线可以自主规划压缩行程，在最安全的状态下达到施工压力，安全生产。从图可以得出，3一5 mm为最佳开孔半径范围，但也应根据实际情况合理选择硅烷改性聚氨酯密封胶胶筒开孔半径的范围。

提出一种无限级键槽式固井滑套和与之配套的梭镖，基于橡胶热疲劳老化力学性能实验，建立梭镖硅烷改性聚氨酯密封胶胶筒三维数值模型，研究了防突环结构参数和硅烷改性聚氨酯密封胶胶筒结构参数等敏感性参数对其密封性能的影响规律，得出以下结论:

(1)综合考虑塑性变形和后续溶解对密封性能的影响，防突环的材料选用镁铝合金材料，防突环的开槽数为4、防突环数量为2时密封效果最好。

(2)硅烷改性聚氨酯密封胶胶筒长度将对密封压力产生显著的影响。随着中间硅烷改性聚氨酯密封胶胶筒长度的增加，最小密封压力整体呈先增大后减小的趋势，综合考虑固井滑套的实际应用需求，建议中间硅烷改性聚氨酯密封胶胶筒的长度为125 mm。

(3)硅烷改性聚氨酯密封胶胶筒的不同开孔形状会对硅烷改性聚氨酯密封胶胶筒密封性能产生显著的影响。综合考虑密封压力、加工性能以及经济性等，半圆形开孔的密封效果最佳。开孔半径也会对密封压力产生影响，当半圆形开孔半径为3一5 mm时密封压力高，密封效果最好。http://www.sdyuantai.com/
