在工程建设中,根据结构设计或施工的需要,常常要留设变形缝或施工缝。这些缝是容易产生渗漏的薄弱部位。所以,选择合理有效的构造措施,是缝防水的关键。传统的处理方法,如企口缝、金属止水片或普通橡胶止水带等,施工麻烦,止水效果不很理想。新型止水材料——遇水膨胀橡胶是一种解决缝防水有效而又方便的材料。一、性能遇水膨胀橡胶既有普通橡胶制品的各种性能,又有遇水膨胀的性能。这种橡胶浸 In the project construction, deformation joints or construction joints are often required for structural design or construction. These seams are weak parts that are prone to leakage. Therefore, the selection of reasonable and effective construction measures is the key to waterproofing. The traditional treatment methods, such as seams, metal waterstops, or ordinary rubber waterstops, are inconvenient for construction and the water-stopping effect is not ideal. The new water-stopping material - water-swellable rubber is an effective and convenient material for solving the seam’s waterproofing. First, the performance of water swelling rubber both ordinary rubber products of various properties, but also the performance of water swelling. This rubber immersion
