                (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.

                       現有建筑幕墻工程質量驗收規范中對硅烷改性聚氨酯密封膠的驗收,通過型式檢驗報告、強制性認證產品的認證標識、進口材料的商檢證明對生產企業的能力進行了確認,對相關產品的質量有了一定的評估;對相關試驗的材料進行見證取樣,確保復驗試驗所用的材料與工程實際所用材料一致,保證了復驗試驗結果的有效性。該驗收方法將硅烷改性聚氨酯密封膠的質量分為材料性能和應用性能兩部分,通過硅酮結構硅烷改性聚氨酯密封膠的邵氏硬度、標準條件拉伸粘結性項目對硅酮結構硅烷改性聚氨酯密封膠的材料性能進行評價、驗收;通過硅酮結構硅烷改性聚氨酯密封膠、硅酮建筑硅烷改性聚氨酯密封膠同實際工程用基材的粘結性和同附件的相容性項目對硅烷改性聚氨酯密封膠的應用性能進行了評價(粘結性項目確定與基材是否粘結良好,相容性項目確定相關附件對硅烷改性聚氨酯密封膠性能是否有影響)。而在進行粘結性試驗時,采用標準基材做標準條件拉伸粘結性試驗(用實際工程用基材進行標準拉伸粘結性試驗,能更好地評判基材和硅烷改性聚氨酯密封膠的粘結質量,但考慮到實際工程中所用的基材種類繁多、形狀也各不相同,試件制備比較困難,可操作性不強);采用實際工程用基材與硅烷改性聚氨酯密封膠進行粘結性試驗;采用實際工程用附件與硅烷改性聚氨酯密封膠進行相容性試驗,形成了一個比較完整、可操作性強的幕墻硅烷改性聚氨酯密封膠粘結系統質量控制體系(圖1)。www.qiquanonline.com
