(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.

根據MS密封膠的材料、結構和加速試驗的相關參數，可確定退化模型中的部分參數值如表3所示，模型中的隨機參數Z、ZZ，比例系數Z、Z，接觸周長的均值#，和標準差擴散系數的均值#，和標準差，初始彈性應力，勃度系數X，密封性能參數R、以及活化能E為待估參數。基于粒子群算法精度高、優化速度快等優點，此處采用粒子群算法對模型參數進行估計。首先，建立一個適應度函數為式中，y(;一12,...,N)為樣品在第;次測試時的實測值均值;夕為樣品在第;次測試時的氣體泄漏率擬合值;N為樣品測試次數。將試驗數據和模型代入下式所示的粒子群算法中進行運算:次迭代后參數走粒子群中粒子d的估計結果;cv)為第次迭代時參數走粒子群中粒子d的數值變化量;為加速因子;V為0一1之間的隨機數;p為參數h粒子群中粒子d搜索到的最優值;p為參數走粒子群中所有粒子搜索到的最優值。

求得待估參數后，分別單獨對每個樣品進行參數估計并得到對應的1,和Y值，根據下式即可得到接觸周長和擴散系數的標準差和為樣品的數量;二、廠為第r個樣品的參數估計值甲為參數估計值的均值。經過多輪迭代即可估算出所需未知參數的值，如表4所示。http://www.qiquanonline.com/
