1.遇水膨胀止水条是一种独特的橡胶新产品,是有遇水膨胀性能的腻子型止水条和制品型止水条的统称。该种橡胶在遇水后产生2-3倍的膨胀变形,并充满接缝的所有不规则表面、空穴及间隙,同时产生巨大的接触压力,彻底防止渗漏。

2.遇水膨胀止水条性能优点:
遇水膨胀橡胶较普通橡胶具有更卓越的特性和优点。该种橡胶在遇水后产生2-3倍的膨胀变形,并充满接缝的所有不规则表面、空穴及间隙,同时产生巨大的接触压力,彻底防止渗漏。当接缝或施工缝发生位移,造成间隙超出材料的弹性范围时,普通型橡胶止水材料则失去止水作用。而该材料还可以通过吸水膨胀来止水。使用遇水膨胀橡胶作为堵漏密封止水材料,不仅用量节省,而且还可以消除一般弹性材料因过大压缩而引起弹性疲劳的特点,使防水效果更为可靠。


3.遇水膨胀止水条质量标准:
a.遇水膨胀橡胶表面应清洁平整,无划痕、气泡及其它杂质,边缘整齐。
b.拉伸强度(Mpa)≥3.5
c.扯断伸长率(%)≥450
c.硬度(邵尔A)(度)42±7
f.静水膨胀率%≥250
