(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.

采用上述工程中使用的質保25年的丁基防水嵌縫膠制成的試樣,在該工程外的其他深圳地區進行同樣的自然老化對比試驗,試驗持續40個月,歷次性能測試結果見表2和圖4。
分析表2和圖4中的結果可以發現,質保25年的丁基防水嵌縫膠在40個月的持續曝曬和自然老化試驗過程中,拉伸粘結強度同樣保持在0.99--1.14MPa之間上下浮動,相對標準偏差僅5.3%,拉伸粘結強度基本保持不變;斷裂伸長率在老化初期略有增加,3.5個月時增加到380%,隨后保持在380%-428%之間上下浮動,相對標準偏差9.0%,仍算穩定。對比試驗中丁基防水嵌縫膠的性能變化趨勢與實際工程中丁基防水嵌縫膠的性能變化趨勢基本一致?梢酝茢,在深圳亞熱帶季風氣候條件下,質保25年的丁基防水嵌縫膠具有優異的耐久穩定性。
采用上述工程中使用的質保25年的丁基防水嵌縫膠制成的試樣,在鄭州地區(溫帶季風氣候)進行同樣的自然老化對比試驗,試驗持續42個月,歷次性能測試結果見表。
分析表3和圖5中的結果可以發現,質保25年的丁基防水嵌縫膠在42個月的持續曝曬和自然老化試驗過程中,拉伸粘結強度始終保持在1.001.13MPa之間上下浮動,相對標準偏差僅5.3%,拉伸粘結強度基本保持穩定;斷裂伸長率在老化初期略有上升,3.5個月時增加到351%,之后一直保持在351%-415%之間上下浮動,相對標準偏差僅6.4%,斷裂伸長率亦基本穩定。由此可以推斷,在鄭州溫帶季風氣候條件下,質保25年的丁基防水嵌縫膠同樣具有較優的耐久穩定性。http://www.ruilingxiang.cn/
