Description

一种热塑性纤维复合丝增强管的制备方法 技术领域
本发明涉及增强管的制备方法，特别涉及一种热塑性纤维复合丝增强管的制备方法。
背景技术
目前，市面上有钢丝网骨架管，钢丝网骨架生产时先挤出一个基管，在基管外面缠绕上钢丝，钢丝的直径和疏密根据承压力不同去选择，缠绕上钢丝之后，外面再包覆上一层PE塑料，形成一个复合的管道，这种管道的优点为承载水的耐压力比较大，但是这种管道也存在着一些缺点，例如当管道受到破坏时，钢丝容易被腐蚀；当管道外层不被破坏，水分子也会浸入，时间久了内部钢丝也会产生腐蚀。此外，管道在输水的时候，当水锤从高处落下时，会对管壁产生冲击力，使钢丝和管体分层。另外，由于管道和钢丝的材质不一样，也会产生分层。钢丝缠绕在基管上，有地地方钢丝密，有的地方钢丝疏，也会造成各个部位的承压力不同。

选择不同规格和不同根数的无机纤维增强热塑性复合丝进行合股，合股的过程中进行加捻，形成纤维束，将纤维束绕到编织机的锭子上，然后放到织布机上进行预备编织；
步骤三：热塑性纤维复合丝增强管的生产
准备基管，在基管外部进行编织纤维束，编织成无结渔网结构形成编织层，然后在无机纤维增强热塑性复合丝外面包覆管道外层，外层材料和基管材质完全一样，最后定长截取，包装入库。
