Description

一种适用于高海拔地区的给水管道及制造工艺
技术领域
本发明涉及给水管道技术领域，具体涉及一种适用于高海拔地区的给水管道及制造工艺。
背景技术
伴随现代工业的飞速发展，水资源在工业生产中显得越来越重要，饮用水在进行输送时经常需要用到管道，特别在高海拔地区，温度低，外部压强小，而通过现有技术制备的饮用水输送管道的抗冻性能较差，在增大管内饮用水的输送压力后，给水管道的，抗压强度不够，这使得在天气比较寒冷时，由于管道内的温度较低从而会降低管道内饮用水的输送效率；再者管道长时间暴露在空气中，其表面的金属成分在空气中水蒸气的作用下发生锈蚀，使得管道的使用寿命缩短。
发明内容
本发明的目的在于提供一种适用于该海拔地区的给水管道及制造工艺，用以解决现有给水管道在高海波地区抗压强度不够，抗冻性较差，导致使用寿命减短等技术问题。
为解决上述技术问题，本发明采用了以下方案：
一种适用于高海拔地区的给水管道，包括给水管道本体，所述给水管道本体由外到内依次为保护层套筒、外层管衬、抗压层、抗冻管衬、内层管衬，所述保护层套筒的外壁喷涂有防腐涂层，所述内层管衬的内壁上喷涂有防水涂层，所述内层管衬和外层管衬之间嵌设有抗压层和抗冻管衬，所述保护层套筒套设固定在所述外层管衬上，所述抗压层内部填充满弹性橡胶体。
进一步地，作为优选技术方案，所述防腐涂层所用的防腐涂料以重量配比计由下列组份组成：水基氯磺化聚乙烯粘合剂30-60份、磷酸三乙酯3.2-4.5份、硫酸钙3.6-4.6份、二氧化钛4.2-5.1份、环氧树脂15-17.2份、邻二甲苯4-8份、鲸蜡硬脂基葡糖多苷3.2-4.3份、防锈剂1.2-2.3份、甲基乙烯酸甲酯3.5-4.8份、固化剂0.9-1.9份；将上述各原料加入到反应釜中，并通过搅拌混合30-60min，
进一步地，作为优选技术方案，所述抗冻管衬所用的抗冻材质由以重量配比计由下列组份组成：普通硅酸盐水泥30-50份、醋酸丙烯－丙烯共聚乳液20-30 份、纤维9-11份、膨胀珍珠岩粉5-9份和矿物棉12-14份，将上述各固体原料粉碎后加水搅拌为料浆，注入成型磨具成型，形成厚度为1.5cm-2.0cm的抗冻管衬，在通风干燥环境待其自然凝固，即得与给水管道内腔匹配的抗冻管衬。
进一步地，作为优选技术方案，所述防水涂层所用的防水涂料以重量配比计由下列组份组成：丙烯酸乳液48-52份、正丁基缩水甘油醚17-20份、三羟甲基丙烷11-13份、聚乙烯醇8-10份、超细硅酸铝4-8份、聚丙烯酸树脂6-9份、乙基纤维素1.5-2.8份、钛白粉5.7-6.1份、纳米碳酸钙8.5-9.1份、丙二醇丁醚1.9-2.3 份和去离子水15-20份，将上述各原料加入到反应釜中，混合搅拌50-70min，即得防腐涂料成品。
进一步地，作为优选技术方案，所述保护层套筒以重量配比计由下列组份组成：PVC树脂30-45份、ABS树脂21-25份、聚碳酸酯树脂15-18份、二氧化硅 4.1-5.3份、碳酸钡粉末2.3-3.2份、金红石型纳米钛白粉5.4-6.2份和氧化锌 3.1-4.2份，芳香胺类抗氧剂3.1-3.8份，将上述各物料放入混合器，混合搅拌 40-60min，得混合物料；混合物料出料温度控制为46-50℃，得到的混合物料置于挤出机内挤出得到管材；管材再经真空冷却后定径和定长切割，最终得保护层套筒。
一种适用于高海拔地区的给水管道制造工艺，包括以下步骤：
S1：用清洗液分别对内层管衬和外层管衬的内、外壁进行清洗，清洗掉一些肉眼可见的杂质，然后再用特定打磨设备对其内外壁进行打磨除锈；即现有电钻机上安装特殊钻头，钻头顶部有与给水管道内腔匹配的柱形砂布，电钻机带动柱形砂布对给水管道内外腔进行打磨除锈；
S2：将防水涂料送至喷涂装置中，通过喷涂装置对内层管衬的内壁上进行喷涂，使得防水涂层紧紧覆盖在内层管衬的内壁上；
S3：将抗冻管衬紧密的包裹在内层管衬的外壁上，将弹性橡胶体紧密的包裹在抗冻管衬外壁上，然后通过气压机将内层管衬、弹性橡胶体和抗冻管衬由右至左压进外层管衬内，然后切平给水管道本体两端面；
S4：利用等离子喷涂工艺将防腐涂料喷涂在外层管衬的外壁上；然后再通过高温固化使粉末牢牢的涂敷在外层管衬表面，最终得到无保护层套筒的给水管道本体；等离子喷涂具有超高温特性，便于进行高熔点材料的喷涂，喷射粒子的速度高，涂层致密，粘结强度高，由于使用惰性气体作为工作气体，所以喷涂材料不易氧化，这样外层管衬上防腐涂料寿命更长久，也更好的保护给水管道不被腐蚀；
S5：将保护层套筒紧密套接在S4中所得的无保护层套筒的给水管道本体的外壁上，最终得到抗压抗冻的给水管道成品。
本发明具有的有益效果：
1、通过在内层管衬和外层管衬之间嵌设抗冻管衬和抗压层，抗冻管衬中的普通硅酸盐水泥、纤维、膨胀珍珠岩粉和矿物棉可以起到很好的保温抗冻效果，从而显著改善饮用水输送管道的抗冻性能，使得在高海拔地区，天气比较寒冷时，由于管道内的温度较低从而会降低管道内饮用水分子的运动速率，从而提高了饮用水的输送效率，抗压层采用弹性橡胶体，在增大给水管道内饮用水的运输压力时，弹性橡胶体收缩会缓冲内部压强对给水管道外层管衬的压力，当内部压力减小后，弹性橡胶体又能恢复原状，能很好的缓冲给水管道内腔的输送压力的变化所带来管壁受力强度的变化，很好的保护给水管道不会因压力过大发生爆管或者裂缝，带来饮用水泄漏，造成资源浪费。
2、防水涂层能减缓内层管衬的内壁因饮用水中少量的水分长时间侵蚀内层管衬内壁的金属组分而造成的内层管衬由内而外被腐蚀的速率，不仅延长了内层管衬的使用寿命，也降低了饮用水泄漏的机率。

一种适用于高海拔地区的给水管道制造工艺，包括以下步骤：
S1：用清洗液分别对内层管衬6和外层管衬3的内、外壁进行清洗，清洗掉一些肉眼可见的杂质，然后再用特定打磨设备对其内外壁进行打磨除锈；即现有电钻机上安装特殊钻头，钻头顶部有与给水管道本体1内腔匹配的柱形砂布，电钻机带动柱形砂布对给水管道本体1内外腔进行打磨除锈；
S2：将防水涂料送至喷涂装置中，通过喷涂装置对内层管衬6的内壁上进行喷涂，使得防水涂层紧紧覆盖在内层管衬6的内壁上；
S3：将抗冻管衬5紧密的包裹在内层管衬6的外壁上，将弹性橡胶体紧密的包裹在抗冻管衬5外壁上，然后通过气压机将内层管衬6、弹性橡胶体和抗冻管衬5由右至左压进外层管衬3内，然后切平给水管道本体1两端面；
S4：利用等离子喷涂工艺将防腐涂料喷涂在外层管衬3的外壁上；然后再通过高温固化使粉末牢牢的涂敷在外层管衬3表面，最终得到无保护层套筒2的给水管道本体1；等离子喷涂具有超高温特性，便于进行高熔点材料的喷涂，喷射粒子的速度高，涂层致密，粘结强度高，由于使用惰性气体作为工作气体，所以喷涂材料不易氧化，这样外层管衬3上防腐涂料寿命更长久，也更好的保护给水管道本体1不被腐蚀；
