(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.

目的:试样暴露在充满so:气体的特定潮湿环境中，通过这种人工模拟的酸雾环境条件来考察丁基防水嵌缝胶的耐老化性能。测试要求:试样放人酸雾试验箱中。试验箱要求:1)将(2.0士o.zL电导率毛0.5mS/m的去离子水或蒸馏水盛于箱子底部;2)试验箱容积为(300士10) L，将0.2 L的SO:气体通人试验箱内，并开始计时，使箱体在1.5 h内升温到(40土3)℃，并维持此温度;3)试样之间的距离不得小于20 mm;试样与箱壁或箱顶的距离不得小于100 mm;试样下端与箱底水面的距离不得小于200 mm;试样与支架的接触面积要尽可能小;4)以24 h为一个试验周期，每个试验周期在箱内曝露8h，然后在室内环境大气中曝露16h;每个周期开始之前，必须更换试验箱内的水和SO:气体，共20个循环;6)处理后的试样在标准条件下放置(24土4) h，然后按要求进行拉伸测试。目的:将试样放人人工模拟的清洁剂环境中，考察清洁剂对丁基防水嵌缝胶性能的影响。

试验要求:1)试样放人(45士2)℃的清洁剂稀释溶液中浸泡21 d，清洁剂采用供应商推荐或实际使用的产品;2)处理后的试样在标准条件下放置(24士4)h，然后按要求进行拉伸测试。接触材料影响—紫外线照射法目的:研究因丁基防水嵌缝胶与其他材料不相容而导致的对结构丁基防水嵌缝胶装配系统(SSGS)稳定性的影响。

试验条件:1)温度:(60士2) ℃ ;2)光源类型:氛灯或同等光源，能量(50士S) W/m2(在样品所处位置测量)、波长范围300-400 nm;3)试验时间:(504士4) h;4)测试丁基防水嵌缝胶与其他产品的相容性，要求5组试样(可能需要使用浅色丁基防水嵌缝胶，方便观察迁移情况)。http://www.sdyuantai.com/
