(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.

隨著機械設(shè)備的改良,目前我國大型中空玻璃用丁基防水嵌縫密封膠生產(chǎn)廠家均已實現(xiàn)自動化生產(chǎn),無論動力、真空密封方式、生產(chǎn)效率及加熱、冷卻系統(tǒng)與原有生產(chǎn)線相比均有大的改善。自動化的稱重配料及密封輸送系統(tǒng),使得產(chǎn)品質(zhì)量進一步得以保障,生產(chǎn)效率提升且車間工作環(huán)境也得以改善。
節(jié)能、安全、耐久性能是中空玻璃的永恒追求目標(biāo),從中空玻璃誕生的那一天起就在不斷探索適宜的輔材。中空玻璃隔熱、隔音、防霜霧性能是通過構(gòu)造中空玻璃的空間結(jié)構(gòu)實現(xiàn)的,其腔體內(nèi)部干燥不對流的空氣(氫氣)層可阻斷熱傳導(dǎo)的通道,從而有效降低制品傳熱系數(shù)以達到節(jié)能的目的。因此,密封材料對氣體阻隔性能或者說透氣率的高低是選用中空玻璃密封膠的重要指標(biāo)之一。中空玻璃水汽和氫氣滲透路徑見圖。
中空玻璃用丁基防水嵌縫密封膠是一種單組份、無溶劑、不出霧、不硫化、具有永久塑性的熱熔性密封膠。丁基防水嵌縫密封膠在較寬溫度范圍內(nèi)保持其塑性和密封性,且表面不開裂、不變硬它對玻璃、鋁合金、鍍鋅鋼、不銹鋼等材料有良好的粘合性。由于其極低的水汽透過率,它可以與彈性密封膠一起構(gòu)成一個優(yōu)異的抗?jié)駳庀到y(tǒng),保證中空玻璃腔內(nèi)氣體的干燥以及防止氫氣的泄露。常用玻璃密封膠性能對比如表1所示。http://www.caffertyclinic.com/
