近年来，越来越多的铝幕墙大面积使用，密封失效也越来越多。铝板密封失效的危险在于幕墙渗漏容易损坏建筑物内部，腐蚀幕墙锚固件，影响建筑物的安全。同时，密封失效会增加建筑物的能耗。在这里，我们将分析铝板密封失效的常见原因，并找到有效的解决方案。
　　In recent years, more and more aluminum curtain walls are used in large areas, and there are more and more sealing failures. The danger of aluminum plate seal failure is that curtain wall leakage can easily damage the interior of the building, corrode the anchor parts of the curtain wall and affect the safety of the building. At the same time, seal failure increases the energy consumption of the building. Here, we will analyze common causes of aluminum plate seal failure and find effective solutions.
　　经常发现铝板的界面使用密封胶会出现裂缝，特别是季节变化，昼夜温差特别大，温度降低时板材收缩，这是由于过度密封胶的拉伸。
　　It is often found that the interface of aluminum plate will crack when sealant is used, especially the seasonal change, the temperature difference between day and night is particularly large, and the plate shrinks when the temperature is reduced, which is due to the stretching of excessive sealant.
　　这主要是因为密封胶的位移能力不符合实际要求。在选择铝板密封胶时，应首选硅酮密封胶，并应选择质量有保证的产品。与其贪便宜，不如选择含有大量“白油”的硅酮密封胶。
　　This is mainly because the displacement capacity of sealant does not meet the actual requirements. In the selection of aluminum plate sealant, silicone sealant should be the first choice, and the quality of the product should be selected. Instead of being cheap, choose a silicone sealant that contains a lot of "white oil".
　　一些不负责任的厂家甚至以此为卖点，因为“白油”价格便宜，可以让新印刷的密封胶表面越来越亮。

　　Some irresponsible manufacturers even use this as a selling point because "white oil" is cheap and can make the surface of newly printed sealant brighter and brighter.
　　很多铝板厂家对这种薄膜都比较重视，但是随着白油逐渐蒸发，胶体本身就会变硬，容易破碎。使用硅酮密封胶时，还应注意产品的保质期。产品过期后，容易造成胶接处产生气泡、性能下降或不固化。
　　Many aluminum plate manufacturers pay more attention to this kind of film, but with the gradual evaporation of white oil, the colloid itself will become hard and easy to break. When using silicone sealant, we should also pay attention to the shelf life of the product. After the expiration of the product, it is easy to cause bubbles, performance decline or non-curing at the adhesive joint.
　　为保证现场施工时密封胶与铝板有良好的附着力，应选用附着力测试报告推荐的清洗剂进行清洗。醇溶剂可能无法有效去除聚酯粉末涂料中的污染物。
　　In order to ensure good adhesion between sealant and aluminum plate during site construction, cleaning agent recommended by adhesion test report should be used for cleaning. Alcohol solvents may not be effective in removing contaminants from polyester powder coatings.
　　使用两步法清洁，使用白色、干净、柔软、吸水、不起毛的棉布，先用浸有溶剂的棉布擦拭，再用第二块干净的棉布填满密封胶以紧密贴合整个界面与密封胶粘合的基板表面上。
　　Use a two-step cleaning process, using a white, clean, soft, absorbent, non-fuzz cotton cloth, first with a solvent-soaked cotton cloth wipe, and then with a second piece of clean cotton cloth filled with sealant to tightly adhere to the entire interface and sealant bonded to the substrate surface.
　　当然防水密封方式很多，结构防水，内部防水，打胶密封，不同的密封方式价格也不尽相同，选择适合的密封方式用于工程中，保证幕墙的功能及外饰效果。您对此还有什么疑问吗？如果有新的疑惑，您可能来网站向我们的客服人员。
　　Of course, there are many waterproof sealing ways, including structural waterproof, internal waterproof and rubber sealing. The price of different sealing ways is not the same. Choose the appropriate sealing way for the project to ensure the function and exterior decoration effect of the curtain wall. Do you have any questions about that?
