(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.

Information

    在使用MS密封胶前,应该核查本年度全性能合格的报告和胶复检报告。复检内容包括:MS密封胶的硬度和23℃拉伸粘结性。

    1)各类密封胶与不同基材的粘结情况

    ①硅酮类与玻璃、铝材和石材粘结效果较好,适用于玻璃、石材幕墙。

    ②聚氨醋类与水泥砂浆板、石材的粘结效果较好,适用于水泥砂浆板块间和石材间的缝隙密封。

    ③聚硫类与玻璃粘结效果较好,适用于中空玻璃的二道密封。

    ④丙烯酸醋类与水泥砂浆板粘结程度相对于其他材料要好,适用于水泥砂浆板间的密封。

    2)幕墙工程中所用的MS密封胶和石材用密封胶应该与MS密封胶相同,增加相容性试验检测。

    3)从检测角度看各类密封胶的污染性。当用密封胶在石材之间、水泥砂浆板块之间密封时,大都存在着对基材污染的问题。聚氨醋类密封胶和丙烯酸类密封胶对基材污染程度较小,而MS密封胶污染程度较大。在石材幕墙应用中,MS密封胶应该使用石材专用MS密封胶,而不宜使用MS密封胶。虽然MS密封胶在检测中能得出无污染的结果,但是由于检测标准存在一些问题,使得在实际工程中用MS密封胶作为石材间密封材料时,经过一段时间后仍然会出现污染现象。www.sdyuantai.com
