摘要
通过在上海的密封胶户外暴露实验，观察到硅酮密封胶周边产生了污染，而MS密封胶则没有出现污染现象；同时，接触角测量仪的数据显示，即便是“非污染”类型的硅酮密封胶，其接缝周边也逐渐变得具有疏水性。开展此类研究，有助于施工人员合理选择密封材料。
The staining of the silicone sealant is observed in out-door exposure test in Shanghai, while the staining of the MS sealant is not observed. Even the joint sealed with non-contaminated silicone sealant becomes hydrophobic according to the data from the contact angle measurement. This kind of research is helpful for builders to choose proper sealing materials.
