不同型号的遇水膨胀橡胶止水条之间有什么不同——橡塑展

伴随着国际橡胶工业的高速增长，橡塑展现已汇集展商700余家，展览面积达50,000平方米，展商来自世界近30个国家和地区，集橡胶机械设备、橡胶化学品、橡胶原材料、轮胎和非轮胎橡胶制品、橡胶循环利用为一体，是橡胶行业相关企业各个环节操作者的年度盛会。今天就由橡塑展小编给大家详细介绍：

遇水膨胀止水条是可以通过吸水使自身体积膨胀变大的一种用于嵌填混凝土建筑缝隙的防水材料。其材质采用的是pn-300型膨胀橡胶，采用这种材质的遇水膨胀橡胶止水条膨胀倍率≥220%～400%，遇水膨胀橡胶止水条主要分为腻子型止水条和制品型止水条2种类别。

腻子型的遇水膨胀止水条硬度低，有一定的柔软性，膨胀率≥220%，多是黑色。像BW型遇水膨胀止水条，缓膨型遇水膨胀止水条，内加网遇水膨胀止水条，带注浆管遇水膨胀止水条都是腻子型的。缓膨型遇水膨胀止水条是一种具有膨胀速度缓慢性能的止水条，多适用于雨水较多的环境使用。内加网遇水膨胀止水条是在一般橡胶止水条的基础上，止水条内添加一层尼龙网或者钢丝网，这种止水条的抗拉伸强度要比一般止水条要高一些，适合垂直缝隙使用，这种带加网的止水条使用很少。带注浆管的遇水膨胀止水条是在止水条内复合一条注浆管，适合施工完的混凝土建筑缝隙出现渗漏水，可通过注浆管注浆堵漏。

制品型的遇水膨胀止水条硬度比腻子型止水条要高一些，有一定的橡胶弹性，多为红色，膨胀率在150%～400%之间可选择。盾构拼接管片之间接缝，混凝土预制管片接缝多采用制品型遇水膨胀止水条。这种制品型止水条采用硫化机热熔工艺加工，拉伸强度在3～3.5MPa。使用中采用质量好的遇水膨胀止水条，可使工程防水质量得到保证。

看完了从中国橡胶助剂网整理的内容，想必您一定很想去了解更多这方面的内容吧？请移步到橡塑展，2021年9月15-17日即将在上海新国际博览中心开展，更多精彩的资讯等你来看！橡塑展期待您的到来。
