(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.

通过Atom Volumes & Sunaces程序计算了3种温度对体系的自由体积、占有体积及自由体积分数的影响丁基防水嵌缝胶/白油、丁基防水嵌缝胶/甲基硅油、丁基防水嵌缝胶/双端乙烯基硅油共混体系随温度变化的自由体积、占有体积及自由体积分数，如图巧所示。

由图巧可知:随着温度的升高，3种混合体系的混合体系在温度为298 K、探针半径为1人时的自由体积及自由体积分数。丁基防水嵌缝胶/白油、丁基防水嵌缝胶/甲基硅油、丁基防水嵌缝胶/双端乙烯基硅油的自由体积和自由体积分数，如图14所示。

由图14可知:丁基防水嵌缝胶/白油体系的自由体积和自由体积分数均最大，说明白油在混合体系中具有更大的相对运动空间，从而为白油的扩散提供了有利条件。而丁基防水嵌缝胶/双端乙烯基硅油混合体系的自由体积和自由体积分数始终是最小的，丁基防水嵌缝胶/甲基硅油混合体系的自由体积分数居中。因此，结合上节相容性优劣分析:分子间的相互作用及分子运动空间大小均导致了白油增塑剂的扩散系数最大，而双端乙烯基硅油的扩散系数最小。通过Atom Volumes & Sunaces程序计算了3种温度对体系的自由体积、占有体积及自由体积分数的影响丁基防水嵌缝胶/白油、丁基防水嵌缝胶/甲基硅油、丁基防水嵌缝胶/双端乙烯基硅油共混体系随温度变化的自由体积、占有体积及自由体积分数，如图巧所示。
