(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.

施工前的检查确认施工条件、接缝的尺寸、是否有缺陷等。被粘基材的清洁、干燥确认被粘基材表面是否干燥，为防止粘结失败对表面的油渍、污垢等等必须用溶剂进行两布擦拭法进行清洁。通常使用的溶剂为甲苯、二甲苯、丁酮，如须溶解涂面时则使用正己烷。衬垫材料(背衬材料、双面胶条等)的填装固定硅烷改性聚氨酯密封胶的尺寸，对于填缝深度不足的情况下，底部须张贴隔离衬垫以防止三面粘结。防污条的粘贴防止防污条陷入被粘面。底漆的涂布底漆涂布厚度适中、均匀不要遗留残料;确保底漆要求的干燥时间的，并在规定时间填充硅烷改性聚氨酯密封胶。对于双组分的硅烷改性聚氨酯密封胶必须对其组分配比进行检测具体方法可用固化时间(很多资料上介绍的扯断时间)与供应商材料的说明对比来判断。施打硅烷改性聚氨酯密封胶一定要将填充缝隙填满硅烷改性聚氨酯密封胶，在修整接缝前借助外力将硅烷改性聚氨酯密封胶向接缝内压实，确保硅烷改性聚氨酯密封胶与被粘结面的充分接触。在结构胶施工时，同时可以进行同批被粘材料的粘结，为粘结检验准备样件。修饰施打硅烷改性聚氨酯密封胶完成后应立即修整接缝，修整时须使修整压力均匀沿一个方向一次完成;然后迅速除去防污条，防止防污条被粘于硅烷改性聚氨酯密封胶或基材之上。

对于耐候硅烷改性聚氨酯密封胶应避开施工现场灰尘较大的交叉施工时期;对于结构硅烷改性聚氨酯密封胶的养护，尤其对单组分结构硅烷改性聚氨酯密封胶应有一能保证环境温度、湿度场所，在冬季较为寒冷地区尤为重要。综合检查检查的重点是硅烷改性聚氨酯密封胶对被粘基材的粘结性。方法可进行单元抽检，也可对粘结检验准备的样件进行粘结检验。以上通用施工程序对建筑幕墙用的耐候硅烷改性聚氨酯密封胶、结构硅烷改性聚氨酯密封胶都适用，更为重要的是按照该程序建立质量的控制系统，方能有效的完成预期的施工质量。真正施工时，对现场施打硅烷改性聚氨酯密封胶后的环境因素的风险分析、高素质施工人员的培训材料供应商最终的技术支持也是非常重要的。http://www.sdyuantai.com/
