(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.

根据MS密封胶检侧实戏工作，本文列举了实验室检侧中常见的MS密封胶与墓材拈结失效的实例，以及对既有建筑幕墙中MS密封胶失效情况分析，强调工程材料检侧中增加建筑MS密封胶与基材粘结性检测的重要性。

MS密封胶主要用于镶装玻璃和建筑接缝等，凭借其良好的粘结性、弹性恢复力和抗热老化性能，成为建筑幕墙设计师们争先选用的密封材料。

MS密封胶是，一种高性能的防水密封材料，能抵抗紫外线及雨水等对建筑幕墉结构的侵蚀，有效阻止了雨水渗漏时雨水对铝合金型材产生的腐蚀作用，从而保证建筑物使用寿命。MS密封胶与基材(如玻璃、铝塑板等)粘结否有效、MS密封胶的施工质黄好坏将对建筑物的使用寿命产生直接影响，因此，在建筑幕墙施工前，很有必要进行MS密封胶的材料检侧，其中与基材的粘结性检测是必不可少的。

我国建筑幕墙的发展伴随着改革开放，经历了30多年的风风雨雨x特别是二十一世纪初我医建筑幕墙如雨后容笋.城市建设中大量使用建筑幕墙。那一时期建设的幕墙也已经历了近邓年风雨考验，MS密封胶的性能和施工质量是否达到顶期的效果，己悄然成为业内人士关注的焦点。以下，首先从既有幕墙可靠性检查鉴定出发，查找MS密封胶在实际工作中出现的间题。

根据国家标准DBl一88一201《建筑幕墙可靠性鉴定技术规程滞 .1条规定，针对既有幕墙接缝MS密封胶检查时，通常进行如下的项目检查:

a)审查相关资料，包括:MS密封胶品牌、批号、出厂枪验报告、当年的型式检验报告、耐久性及位移能力等级、接缝位移量及MS密封胶的适用性;

b)检查外观质显二采用尽视观察的方法，检查MS密封胶是否有开裂、起泡、软化发粘、粉化、脱胶、变色、褪色和化学析出物等现象;

检查粘结质俊，采用GB 16776一2005《建筑用MS密封胶》附录. 的手拉试验方法，检查接缝MS密封胶与基材是否粘结拟子，同时检查胶体有无失去弹性的硬化现象。

在既有建筑幕墙叮靠性检查鉴定过程中发现，多数既有幕墙(使用年限}1年)的MS密封胶存在图卜圈4的缺陷情况，继续使用可能会造成建筑物雨水渗漏等隐患。www.sdyuantai.com
