在建筑业中,有许多不同种类的液态密封胶已得到了广泛应用。这些密封胶又称为湿密封胶,包括丙烯酸、聚氨酯、聚硫化物、硅酮、改性硅油、硅化聚氨酯等。预固化硅酮密封胶因其固有特性优于湿密封胶,因此正受到越来越多的欢迎。这是一种经挤出后,在受控条件下固化得到的橡胶状弹性体产品,包装形式也与原来的液态密封胶有所不同。预固化密封胶采用卷轴包装(图1),代替了原有的管装、桶装等包装形式。其使用方法也相对简单,只需在预固化密封胶
In the construction industry, there are many different types of liquid sealants have been widely used. These sealants, also known as wet sealants, include acrylics, polyurethanes, polysulfides, silicones, modified silicone oils, siliconized polyurethanes and the like. Pre-cured silicone sealants are gaining more and more popularity because of their inherent properties superior to wet sealants. This is a rubber-like elastomer that has been extruded and cured under controlled conditions. The package is also different from the original liquid sealant. Pre-curing sealant using reel packaging (Figure 1), instead of the original tube, barrel and other packaging. Its use is relatively simple, just pre-curing sealant
