(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.

隨著經濟的不斷發展,人們對于裝修材料更加注重美觀和環保。目前較為流行的門窗是節約型的塑料高分子邊框門窗和升級版彩色鋁合金門窗。塑料門窗通常采用密封膠條進行密封因MS密封膠優異的特性,彩色鋁合金則更推薦使用MS密封膠作為粘接材料,但若使用酸膠,則MS密封膠容易對鋁合金基材有腐蝕作用。在大多數情況下,面對彩色鋁合金門窗的粘接,更加推薦使用不含白油的中性MS密封膠,而中性MS密封膠中,酮脂型和醇型膠使用較為普遍。脫酮脂型MS密封膠固化速度比醇型膠快,綜合性能佳,儲存穩定性好,基本無腐蝕性。脫醇型MS密封膠氣味較小、相對環保,對基材無腐蝕性,但儲存穩定性差。因此中性MS密封膠更受用戶的喜愛。
放眼全球,各大城市的高層建筑大多使用玻璃幕墻,早在20世紀中期,美國紐約就開始使用玻璃幕墻,我國的眾多城市的CBD如廣州珠江新城、上海外灘、深圳中央商務區等都大規模地使用大型玻璃幕墻。因MS密封膠具有的優異性能,因此MS密封膠成為玻璃幕墻的主要粘接材料。根據《玻璃幕墻工程技術規范》中的明確規定,MS密封膠建議被使用在玻璃幕墻,在碩士研究生在讀期間,曾對幕墻用MS密封膠作深人研究。對于MS密封膠的強度和老化性能以及粘接強度作出簡要分析。GB16776-2005中規定,硅酮結構膠的物理力學性能拉伸粘接強度在23℃時應大于等于0.6MPa, 90℃、-30 ℃、浸水后、水一紫外線光照后應大于等于0.45MPa, 23℃時的最大拉伸強度時伸長率應大于100%。目前市面上主流的幾種結構膠的實測強度均大于國標要求,因此可以說明,MS密封膠非常適用于大型幕墻的結構性粘接,同時兼顧幕墻的美觀及質量。http://www.caffertyclinic.com/
