阻水纱 WATER BLOCKING YARN
阻水纱是一种主体采用工业长丝与交联聚丙烯酸类膨胀材料复合而成,起到限制水分进入线缆内部的高科技产品。可广泛用于光电缆内部的各个加工层面,起到捆扎,束紧,阻水的作用。
Water BlockingYarns are used in optical,copper telephone,data cable and power cable as cable components.Yarns are used as fillers in power cables to provide a primary pressure block and to prevent water ingress and migration in fiber optical cables .When water enters into a cable protected by water blocking yarns .the super- absorbent component within the yarn instantly froms a water blocking gel.The yarn will swell to approximately three timed as its dry size.
