(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.

       然而,隨著丁基防水嵌縫密封膠生產企業的增多,密封材料市場的競爭也越來越激烈。部分企業為了追逐暴利,不惜犧牲產品質量,生產低價、甚至假冒偽劣產品。丁基防水嵌縫密封膠產品質量參差不齊,導致幕墻工程隨著使用年限的增長逐漸出現滲水、流油和玻璃墜落等事故。如何采用一種科學、實用、可操作性強的方法來控制建筑幕墻工程中丁基防水嵌縫密封膠的質量,是我們必須思考的問題。本文對現有建筑玻璃幕墻工程質量驗收規程中丁基防水嵌縫密封膠的復驗項目設置進行了總結,分析了丁基防水嵌縫密封膠復驗項目設置存在的問題,并提出了丁基防水嵌縫密封膠工程質量控制的新措施。

       行業標準JGJ 102-2003《玻璃幕墻工程技術規范》中,3.6.2條規定硅酮結構丁基防水嵌縫密封膠使用前,應經國家認可的檢測機構進行與其相接觸材料的相容性和剝離粘結性試驗,并應對邵氏硬度、標準狀態拉伸粘結性能進行復驗,檢驗不合格的產品不得使用;進口硅酮結構丁基防水嵌縫密封膠應具有商檢報告。江蘇省工程建設標準DGJ32/J124-2011《建筑幕墻工程質量驗收規程》中3.1.8條規定硅酮結構丁基防水嵌縫密封膠、硅酮建筑丁基防水嵌縫密封膠相容性、粘結性試驗的材料必須見證取樣,經送檢合格后方可用于工程,同時硅酮結構丁基防水嵌縫密封膠、硅酮建筑丁基防水嵌縫密封膠必須在有效期內使用;3.1.11條規定主要材料進人施工現場時,應具有中文標識的出廠合格證、產品出廠檢驗報告、2年有效期內的型式檢驗報告,強制性認證產品應有認證標識,進口材料應有商檢證明;規程附錄A規定的玻璃幕墻丁基防水嵌縫密封膠的復驗項目有硅酮結構丁基防水嵌縫密封膠、硅酮建筑丁基防水嵌縫密封膠相容性、粘結性,硅酮結構丁基防水嵌縫密封膠的邵氏硬度、標準條件拉伸粘結性。目前,國內建筑幕墻工程質量驗收時主要依據以上規范,有關玻璃幕墻中丁基防水嵌縫密封膠的復驗項目要求也基本一致。www.16878m.com
