| 在Dryflex WS系列中，我们将热塑性弹性体（TPE）的一般耐水性能改为在浸入水中时能膨胀到体积10倍的材料。这些材料在与水溶液（pH7-12）接触时会膨胀，形成正密封，防止水进入或流出。材料科学已经开发出一系列配方，当浸入水中时，膨胀率从300%到1000%。当不再有水存在时，化合物收缩回原来的大小，这是一个可以无限次重复的膨胀和收缩过程。这些化合物具有坚实的结构完整性，不像许多等效的粘土基产品，它们会随着时间的推移而腐蚀和破碎。水膨胀性TPE以任何颜色混合，100%可回收，可使用传统的制造方法进行加工，包括挤压和注射成型。可提供抗菌版本。应用：止水带、建筑和建筑、水处理厂、隧道、排水沟、下水道、水箱、汽车密封胶部件、玻璃、前照灯和电缆保护只是Dryflex WS材料的几个潜在应用。我们开发了更软的等级，提供了出色的悬垂性。它们是止水应用的理想选择，在止水应用中，剖面可能是盘绕的，或者需要安装在复杂结构周围。 With the Dryflex® WS range we have turned the usual water-resistant properties of thermoplastic elastomers (TPE) on their head to create materials that swell up to ten times their volume when immersed in water. These materials have been developed to expand upon contact with aqueous solutions (pH7 to 12) to form a positive seal and prevent the ingress or exit of water. Material Science A range of formulations have been developed which offer different swell rates when immersed in water. When there is no longer water present the compound shrinks back to its original size, a process of expansion and contraction that can be repeated an unlimited number of times. The compounds have solid structural integrity; unlike many of the equivalent clay based products which can erode and shatter over time. Compounded in any colour, the water swellable TPE is 100% recyclable and can be processed using conventional fabricating methods, including extrusion and injection moulding. Antimicrobial versions are available. Applications One of the main applications for Dryflex WS compounds are hydrophilic waterstops. These are typically used as part of a concrete structure and intended to prevent the passage of fluids (e.g. water) when embedded in and running continuously through concrete joints. We have developed softer grades which offer excellent drapability. They are an ideal choice for waterstops where the profiles may be coiled or need to be fitted around complex structures. Other applications for Dryflex WS TPE compounds include tunnels, water treatment plants, drains, sewers, tanks, glazing and cable protection. |
