增强热塑复合结构壁管管材、 带材及其成套生产装置
技术领域
本发明涉及增强热塑复合结构壁管技术领域， 特别涉及一种增强热塑复合结构壁管管材、 带材及其成套生产装置。
背景技术
水资源的保护是保护生态环境的重要组成部分。 目前， 造成地下水污染的主要原因是城市 或工业排污管道的渗漏， 为此传统的铸铁管、 钢筋混凝土管已逐渐或正在被各种类型的埋地用 塑料结构壁管材所替代。
塑料结构壁管有两种主要工艺： 直接挤出成型和缠绕成型。 缠绕成型的塑料结构壁管是由 塑料中空带材或塑料异型带材连续缠绕而成， 这种工艺既适用于较大口径， 也适用于全尺寸规 格系列的塑料结构壁管的制造。
推广这种塑料结构壁缠绕管的最大难点在于不能保证铺设施工的质量。 由于种种条件的限 制， 并不是所有的工程都能够保证管道周围的回填材料达到规定的压实程度， 比如铺设场地的 土壤条件较差、 承受的负载较重， 或者虽然能够达到但是工程费用太高， 例如需要从外地购买 和运进全部回填材料， 在这种情况下釆用较高环刚度的管道常常是必须的或者是更经济的。
全塑料结构壁管由于材料弹性模量比较低， 需要耗用较多的材料才能达到要求的环刚度。 例如： 内径 2000mm ， 环刚度 SN8 的全塑料缠绕结构壁管米重达到 499公斤。无论塑料结构 壁管有多少优点， 如果价格太高， 用户也很难接受。

从上述的技术方案可以看出， 本发明提供的增强热塑复合结构壁管具有如下突出优点： 一是可以提高管材环刚度， 以增强型材为钢带， 热塑材料以聚乙烯为例， 钢的弹性模量是 聚乙烯的 200倍以上（碳素钢的弹性模量在 190000 Mpa左右， 聚乙烯的弹性模量在 800Mpa 左右） ， 在大弹性模量钢材的作用下， 增强热塑复合结构壁管可轻易达到 SN16 ( kN/m2 )或以 上的环刚度， 弥补了较大直径全塑料结构壁管一般环刚度较难达到 SN8 或以上的弱点。 因此在 各种使用条件下的工程中都可以釆用。 例如在某些沿海地区， 由于土壤中含腐蚀性物质， 如果 使用混凝土管工作寿命会很短， 但是当地的土壤承载能力很差， 地下水位又高， 过去因为没有 高环刚度的塑料结构壁管产品无法满足设计要求， 现在就可以釆用增强热塑复合结构壁管。
二是原材料的消耗量显著较少， 上述增强热塑复合结构壁管最重要最突出的优点就是在达 到高性能的同时， 非常显著地节约原材料。 众所周知， 一项技术创新能够降低材料消耗 10% 通 常就认为是重要成果。 增强热塑复合结构壁管和全塑缠绕结构壁管相比在同样直径同样环刚度 下材料米重将减少近一半， 成本的降低将更多。 原因就在钢的弹性模量比聚乙烯大 200倍， 钢 塑复合加强结构达到的环刚度远超过多层厚实的聚乙烯结构层产生的效果。 适当设计增强型材 复合加强结构的厚度和高度就可以轻易地达到要求的环刚度。以环刚度 SN8 为例，在全系列规 格尺寸中增强热塑复合结构壁管和全塑缠绕结构壁管的米重比在 0.35-0.61 。 值得注意的是在 增强热塑复合结构壁管的米重内大约近一半是聚乙烯的重量， 另一半是钢材的重量。 钢材的价 格大约是聚乙烯价格的一半。 以内径 2000mm , 环刚度 SN8 为例， 全塑料缠绕结构壁管米重 高达到 499公斤， 增强热塑复合结构壁管总的米重为 170公斤， 折合材料成本降低至全塑管的 25% , 消耗的聚乙烯为 85公斤仅为全塑管的 17% 。 在全系列规格尺寸中增强热塑复合结构 壁管的材料成本不到全塑缠绕结构壁管的三分之一， 消耗的聚乙烯材料不到全塑管的五分之一， 在塑料原材料价格爆涨的经济形势下是非常有价值的应对措施。
增强热塑复合结构壁管既保留了塑料管材具有优良的水力特性， 极强的内外防腐能力及适 度的轴向柔韧性等优点，又以大弹性模量增强材料优化支撑结构，可使管材以较低的材料成本， 具备抵抗土壤载荷的足够环刚度， 因此具有卓越的综合性能。
