              (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.

                     自由體積均隨之升高。且在相同溫度下,自由體積大小順序均為:MS密封膠/白油>MS密封膠/甲基硅油>MS密封膠/雙端乙烯基硅油。此外,自由體積越大,越有利于分子鏈的運動和伸展,故白油容易發生擴散。同時從圖巧中可以看出,隨著溫度升高,各混合體系的自由體積分數均增大。這說明溫度的升高使增塑劑分子的運動能量提高,與MS密封膠分子間的距離增加,增加了分子的運動空間,從而更有利于分子發生擴散。此外,在相同溫度下,自由體積分數的大小順序也均為:MS密封膠/白油>MS密封膠/甲基硅油>MS密封膠/雙端乙烯基硅油。

                     綜合以上兩方面分析:隨著溫度升高,MS密封膠與增塑劑分子間的相互作用減弱,使增塑劑擴散能力增強。且隨著溫度的升高,各混合體系內的自由體積及自由體積分數均隨之增加,這為增塑劑分子的擴散提供了有效的運動空間,因此使增塑劑更易在體系中發生擴散。

                     各混合體系隨增塑劑含量變化的自由體積及自由體積分數,如圖16所示。

                     由圖16可知:隨著增塑劑含量的增加,各混合體系的自由體積和自由體積分數均隨之升高。在相同條件下,體系的自由體積及自由體積分數的大小順序均為:MS密封膠/白油>MS密封膠/甲基硅油>MS密封膠/雙端乙烯基硅油。這說明增塑劑含量的升高不僅使增塑劑分子鏈本身更易伸展和轉動,而且為增塑劑分子增加了有效運動空間。http://www.caffertyclinic.com/
