(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.

      GB/T14683-2017《硅酮和改性硅酮建筑硅烷改性聚氨酯密封膠》標準于2017年9月7日發布,于2018年8月1日實施。標準首次將改性硅酮建筑硅烷改性聚氨酯密封膠(MS)的性能單列作了要求,并對其中的應力緩和型硅烷改性聚氨酯密封膠的性能表征、技術指標及試驗方法進行了規定。本文介紹了該標準中應力緩和型硅烷改性聚氨酯密封膠產品的概況、性能表征、術語和定義、驗證試驗及結果分析等。GB/T 14683-2017《硅酮和改性硅酮建筑硅烷改性聚氨酯密封膠》標準于2017年9月7日發布,于2018年8月1日實施。標準首次將改性硅酮建筑硅烷改性聚氨酯密封膠(MS )的性能單列作了要求,并對其中的應力緩和型硅烷改性聚氨酯密封膠的勝能表征、技術指標及試驗方法進行了規定。

       工業化生產的裝配式預制混凝土外掛墻板(在日本稱為窯業板)施工后由于受到干縮的影響,導致板塊之間的接縫擴大,接縫中的硅烷改性聚氨酯密封膠將長期受到拉應力的作用,嚴重影響接縫密封的耐久性。為了減緩接縫干縮位移對硅烷改性聚氨酯密封膠本體和粘結界面的應力,提高接縫密封的耐久性,有關方面研制出了用于此類接縫的具有應力緩和性能的建筑硅烷改性聚氨酯密封膠,即本標準中規定的R類(應力緩和型)建筑硅烷改性聚氨酯密封膠。http://www.16878m.com
