(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.

建筑的保温性能对于提高室内舒适度、降低能源消耗至关重要。在幕墙中，聚氨酯密封胶作为连接和密封材料，其性能直接影响幕墙的整体保温效果。本工作采用单一变量试验方法，研究建筑幕墙密封用多孔硅酮聚氨酯密封胶的制备及保温性能，以期探索多孔硅酮聚氨酯密封胶的热传导特性，提高幕墙的整体保温性能。

多孔硅酮聚氨酯密封胶制备

多子L硅藻土预处理

多孔硅藻土作为制备多孔硅酮聚氨酯密封胶的关键材料，需进行预处理才能获得较好的应用效果，其预处理步骤如下。

(1)准备原料:主要原材料为多孔硅藻土，辅助材料包括聚丙烯纤维等。

(2)粉磨和分级:将多孔硅藻土进行粉磨，得到粒径较小的多孔硅藻土粉末，然后进行分级处理，收集一定粒径范围的多孔硅藻土分别收集。

(3)除杂:通过物理或化学方法去除多孔硅藻土中的杂质，如铁、钙等离子。

(4)活化:通过化学或物理方法对多孔硅藻土进行活化处理，以提高其吸附性能和离子交换能力。

(5)干燥:将处理后的多孔硅藻土进行干燥，使用减水剂去除其中的水分。

(6)包装:将预处理后的多孔硅藻土进行包装，以备后用。http://www.sdyuantai.com/
