1.EVA止水带是以高分子树脂为主要原料，经特殊工艺加工挤出成型的一种新型止水材料。它与防水板焊接后形成了混凝土构筑物迎水面第一道止水防线，对于混凝土变形缝渗漏的预防至关重要。EVA止水带的选取用应考虑到与衬砌混凝土用防水板的焊接固定，应选用与防水板分子结构性质相同的塑料止水带，近年来国内防水板的种类主要分为EVA、ECB、PE、HDPE等几种材质，我公司以各种不同防水板为载体，在原有PVC塑料止水带生产的基础上，又先后开发成功了一系列高分子树脂止水带，能满足各种工程的不同需求，施工简便、成本适中，是一各理想的新型防水材料。
The 1.EVA water stop belt is a new type of water stop material which is extruded by special process with polymer resin as the main raw material. It has formed the first water stop line at the surface of the concrete structure after welding with the waterproof board, which is very important for the prevention of the seepage of the concrete deformation joint. EVA waterstop used should be taken into account and lining concrete with fixed welding waterproof board, should use the same molecular structure and properties of waterproof board plastic waterstop in recent years, the domestic type of waterproof board is divided into several EVA, ECB, PE, HDPE and other materials, our company with different kinds of waterproof board as the carrier in the original PVC, the plastic waterstop production basis, and has successfully developed a series of polymer resin water stop, to meet the different needs of various projects, the construction is simple, the cost is moderate, is the ideal of a new waterproof material.
2.EVA止水带适用范围：可应用在任何地面或地下建筑，形成一道长久而坚固的隔水屏障，特别适用于储水和挡水的结构，例如水库、污水池、水坝、地铁、隧道挡水墙等。
The application scope of the 2.EVA waterstop is that it can be applied to any ground or underground building to form a long and strong water barrier, especially for the structure of storing water and retaining water, such as reservoir, sewage pond, dam, subway, tunnel retaining wall and so on.
3.EVA止水带注意事项：用户在施工过程中，由于混凝土中有许多尖角的石子和钢筋，操作时要注意避免对塑料止水带造成机械损伤。在定位塑料止水带时，要使其与混凝土界面贴合平整，不能出现止水带翻转、扭曲等现象，否则应及时进行调正。在浇筑固定止水带时，应防止止水带发生偏移，影响止水效果。止水带接头可利用粘接、热焊接等方法，保证接头牢固。浇注混凝土过程中要注意充分震捣，以达到止水带和混凝土充分结合。
3.EVA waterstop notices: during the course of construction, users should pay attention to avoid mechanical damage to the plastic sealing belt when there are many sharp stones and reinforcing bars in the construction process. When locating the plastic water stop, the interface between the plastic and the concrete must be smoothed and smooth, so that the phenomenon of turning and twisting can not appear. Otherwise, it should be adjusted in time. When fixing the fixed water stop belt, the migration of the water stop zone should be prevented and the effect of water stop should be affected. The joint of the water stop belt can be used for bonding and hot welding to ensure the joint firmly. In the process of pouring concrete, we should pay attention to the full earthquake, so as to achieve the full combination of water stop and concrete.
