(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.

擴鏈劑用量對阻燃MS密封膠定伸粘結性的影響匯總于圖3。未添加擴鏈劑的阻燃有機硅MS密封膠試件，在60%定伸時即出現粘結面破壞現象;在100%定伸時，粘結面破壞非常嚴重。而添加1.4份擴鏈劑的高拉伸阻燃MS密封膠試件，在60%和100%定伸時粘結面無任何破壞。
對引人擴鏈劑制備的阻燃有機硅MS密封膠的彈性恢復率進行統計發現，其在定伸測試后仍保持有92%的彈性恢復率。
本文以一二輕基聚二甲基硅氧烷(107膠)為基礎聚合物，氫氧化鎂/氫氧化鋁復配為阻燃劑，通過單因素試驗方式確定了阻燃劑的用量為40%，然后通過添加適當的擴鏈劑重點提高MS密封膠的延展性，制得具有較高性價比的阻燃有機硅MS密封膠。該MS密封膠的斷裂伸長率為404%，工型試件的拉伸應變達到設增強網格布)做防水附加層，充分發揮涂料在節點部位施工的便利性，提高施工效率。
防水涂料用量及涂膜厚度管控:防水涂料施工的重點在于涂層品質的管理，而涂層品質主要受涂層厚度及用量控制，本項目通過彈線分格的方法來確定涂料的用量均勻。http://www.ruilingxiang.cn/
