(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.

由圖可得到2種密封結構MS密封膠膠筒組與井壁間的接觸力，如表所示。與常規結構相比，新型密封結構各MS密封膠膠筒與中心管間的平均接觸壓力有很大提高，其中上MS密封膠膠筒接觸壓力提高了62.84%，中膠筒提高了82. 73 %，下MS密封膠膠筒提高了73. 87%。由此可見，新型密封結構大大提高了MS密封膠膠筒組與中心管間的接觸壓力，保證了MS密封膠膠筒組的密封性能，在一定程度上對防止出現滲漏起了重要作用。

MS密封膠膠筒硬度的影響

封隔器MS密封膠膠筒的硬度范圍一般為IRHD 60一95，在上防凸環向下加載位移32 mm，研究不同硬度下常規和新型密封結構MS密封膠膠筒組與井壁間的接觸壓力分布情況，結果如圖所示。

可以看出:在受到大小為32 mm的相同位移載荷條件下，2種MS密封膠膠筒組的接觸壓力整體分布趨勢基本一致;隨著硬度的增大，接觸壓力均增大，其中常規密封結構MS密封膠膠筒的最大接觸壓力從1 MPa增大到5 MPa，而新型密封結構MS密封膠膠筒的最大接觸壓力從1. 5MPa增大到7. 8 MPa;新型密封結構各MS密封膠膠筒的平均接觸壓力始終大于常規密封結構。

摩擦因數的影響

受井下復雜情況的影響，摩擦因數的選取比較困難。設定MS密封膠膠筒與井壁的摩擦因數戶為0. 1一0. 7，研究了向下加載犯軸向位移載荷條件下2種密封結構MS密封膠膠筒組與井壁的接觸壓力分布，結果如圖所不。http://www.kubee.cn/
