(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.

       隨著玻璃幕墻使用年限的增長,中空玻璃內部流油污染的現象時有發生,且成逐年增加的趨勢。出現上述現象絕大部分是由于工程中使用了劣質的硅烷改性聚氨酯密封膠。這些劣質的硅烷改性聚氨酯密封膠中加人了大量白油等低分子烴類化合物,在滲透壓作用下低分子烴類化合物透過硅橡膠分子間交聯網絡,形成中空玻璃內表面的滲流產物;油溶性的丁基膠接觸白油時可被溶脹、潰溶,在油流中形成黑色膠塊,最終導致中空玻璃“流淚”甚至發生玻璃脫落,在造成幕墻工程大面積返工、人力物力巨大浪費的同時,也給幕墻安全埋下隱患。出現上述結果的原因歸根結底是沒有做硅烷改性聚氨酯密封膠與中空膠、丁基膠的相容性,未能通過前期篩選來規避耐候膠與中空膠、丁基膠之間的相互影響。事實上,現有建筑幕墻工程質量驗收中對密封膠的復驗項目并無規定耐候膠與中空膠、丁基膠的相容性。www.16878m.com
