(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.

Information
四川某醫(yī)院大樓，隱框玻璃幕墻使用白云牌丁基防水嵌縫膠，建于2005年。幕墻服役14年時(shí)調(diào)研結(jié)果:丁基防水嵌縫膠硬度在4446之間，與基材粘結(jié)良好。至今，幕墻已服役17年，使用狀況良好，未出現(xiàn)任何失效狀況。
廣州某廣場，隱框玻璃幕墻，建于1996年，幕墻服役24年時(shí)調(diào)研結(jié)果:隱框玻璃幕墻丁基防水嵌縫膠與基材粘接良好，硬度適中，彈性仍然很好，可以繼續(xù)使用。
深圳某大樓，隱框玻璃幕墻，建于1998年，幕墻服役19年時(shí)調(diào)研發(fā)現(xiàn):隱框玻璃幕墻丁基防水嵌縫膠與基材粘接良好，硬度在3 746之間，硬度范圍較大，但丁基防水嵌縫膠總體狀況仍較好。
此次調(diào)研中，其中7個(gè)項(xiàng)目丁基防水嵌縫膠有一定程度的老化(丁基防水嵌縫膠非白云品牌)，丁基防水嵌縫膠硬度增加、彈性下降;部分典型項(xiàng)目具體調(diào)研結(jié)果如下。
深圳某大廈，隱框玻璃幕墻，建于1992年，幕墻服役24年時(shí)調(diào)研結(jié)果:隱框玻璃幕墻丁基防水嵌縫膠已經(jīng)基本硬化，彈性比較差。
上海某廣場，半隱框玻璃幕墻，建于1999年，幕墻服役23年時(shí)調(diào)研結(jié)果:半隱框玻璃幕墻丁基防水嵌縫膠與基材粘接良好，還有一定的彈性，但硬度上升明顯，超過600。
杭州某廣場，半隱框玻璃幕墻，建于1999年，幕墻服役23年時(shí)發(fā)現(xiàn):半隱框玻璃幕墻丁基防水嵌縫膠與基材粘接良好，硬度超過60，彈性一般。
另外，有4個(gè)項(xiàng)目丁基防水嵌縫膠老化情況比較嚴(yán)重(丁基防水嵌縫膠非白云品牌)，部分典型項(xiàng)目具體調(diào)研結(jié)果如下。
廣州某隱框玻璃幕墻項(xiàng)目，幕墻服役22年時(shí)對其丁基防水嵌縫膠進(jìn)行檢測和取樣。經(jīng)檢測，硬度為30，彈性尚可。采用“重新粘結(jié)法”測得標(biāo)準(zhǔn)條件下的拉伸粘結(jié)強(qiáng)度平均值為O.SSMPa，不滿足GB 16776中標(biāo)準(zhǔn)條件下拉伸粘結(jié)強(qiáng)度不低于0.60MPa的要求，已對幕墻安全造成威脅。http://www.cs535.com/
