Description

大口径双壁波纹管制备方法
技术领域
本发明属于双壁波纹管领域，尤其是涉及一种大口径双壁波纹管制备方法。
背景技术
由于双壁波纹管具有重量轻、耐腐蚀、不结垢、寿命长等特点，因此，其作为一种高性价比的排水管被广泛应用于排水等领域。而普通的PVC-U双壁波纹管低温性能较差，储运、施工过程中破损率较高，而且管径较小，口径在500mm以上成型困难；同时含铅盐稳定剂，长期使用易污染水资源和土壤。而PE缠绕管与同口径管材相比单位米重较重，并且生产速度低，很难满足大型工程需求，而且端面密封较困难，易破损。
发明内容
本发明要解决的问题是提供一种大口径双壁波纹管制备方法，尤其指出了增大口径工艺技术的创新。
为解决上述技术问题，本发明采用的技术方案是：一种大口径双壁波纹管制备方法，包括以下步骤：
(1)将高密度聚乙烯树脂、色母和消泡剂按照30:19:1进行混合，混合均匀后进行加热，加热温度控制50-60℃，搅拌时间约5-12分钟；
(2)将混合完成的物料放入挤出机的料斗进行恒温干燥，温度控制70-80℃，干燥时间100-120分钟；
(3)将干燥完成的物料放入两台挤出机进行螺杆塑化，其中一台挤管材外壁，一台挤管材内壁；两台挤出机熔体温度均控制200-205℃，熔体压力均控制≤30MPa，形成内管坯和外管坯；
(4)物料通过挤出机螺杆加热熔融塑化输送至机头口模；
(5)管材内壁通过内径决定径套抽真空水冷却定型；管材外径经过自动控制的成型机传动，模块抽真空进行冷却定型；
(6)经过冷却定型后进行计长切割、双层壁承插、堆放，成品检验后完成成品入库；
进一步，管材外壁呈波纹状。
本发明具有的优点和积极效果是：双层壁承插口的柔性连接保证了双层波纹管密封性能好，同时本发明具有口径大、环刚度高、耐低温等优点。
附图说明
图1是本发明的制备工艺流程图。
具体实施方式
如图1所示，本发明提供了一种大口径双壁波纹管制备方法，包括以下步骤：
(1)将高密度聚乙烯树脂、色母和消泡剂按照30:19:1进行混合，混合均匀后进行加热，加热温度控制50-60℃，搅拌时间约5-12分钟；
(2)将混合完成的物料放入挤出机的料斗进行恒温干燥，温度控制70-80℃，干燥时间100-120分钟；
(3)将干燥完成的物料放入两台挤出机进行螺杆塑化，其中一台挤管材外壁，一台挤管材内壁；两台挤出机熔体温度均控制200-205℃，熔体压力均控制≤30MPa，形成内管坯和外管坯；
