PVC空心缠绕管的发展历程!

作者: admin    来源:http://www.laobingguandao.com  时间:2019-12-30    人气:
  在PVC空心缠绕管发展的初期,PE管的消耗量远远低于PVC管,而钢带管的主要原因是经济性。当时高性能的PE管材还没有开发出来,只能使用性能相当于PE63级的PE材料。由于强度低,在相同条件下,PE管的壁厚比PVC管的壁厚大1倍以上。不仅材料成本高,而且只能应用在压力小、直径小的管道上,否则壁厚太大无法使用。随着研发力度的不断加大,新一代高强度管材PE材料不断涌现,不仅有PE80,还有PE100产品。材料的更新换代使PE管的应力明显增大,管壁厚度越来越薄,甚至低于PVC管。
  In the early stage of PVC hollow winding pipe development, the consumption of PE pipe is far lower than that of PVC pipe, and the main reason of steel strip pipe is economy. At that time, high-performance PE pipes had not been developed, only PE materials with performance equivalent to pe63 could be used. Because of the low strength, under the same conditions, the wall thickness of PE pipe is more than one time larger than that of PVC pipe. Not only the material cost is high, but also it can only be used in the pipeline with small pressure and diameter, otherwise the wall thickness is too large to use. With the continuous increase of R & D efforts, new generation of high-strength pipe PE materials are emerging, not only PE80, but also PE100 products. The stress of PE pipe increases obviously with the renewal of material, and the thickness of pipe wall becomes thinner and thinner, even lower than that of PVC pipe.
  PVC中空包装管挤压波纹外墙和一层光滑的内壁的HDPE同时,管壁部分是双层结构,内壁光滑,光滑,外墙是一个梯形的管空心结构安排在相同的时刻。具有优异的环刚度,强度和韧性好,重量轻,抗冲击能力强,不易损坏,便于运输和安装。管道主要采用橡胶圈承插连接(也可采用热缩带连接)。由于特殊的波纹管管壁结构设计,使得管材在相同直径和达到相同的环刚度时,材料(HDPE)更少。然而,由于受到生产技术的限制,国内大口径的生产仅为DN1200,因此其推广有限。

  PVC hollow packaging pipe extrudes corrugated outer wall and a layer of smooth inner wall HDPE. Meanwhile, the pipe wall part is double-layer structure, and the inner wall is smooth and smooth. The outer wall is a trapezoid pipe hollow structure arranged at the same time. With excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, not easy to damage, easy to transport and install. The pipe is mainly connected by rubber ring socket (or heat shrinkable belt). Due to the special structural design of corrugated pipe wall, the material (HDPE) is the least when the pipe has the same diameter and the same ring stiffness. However, due to the limitation of production technology, the domestic production of large caliber is only DN1200, so its promotion is limited.
  PVC中空缠绕管的挤出及注塑加工,加工辅助PVC动力管对塑化质量的作用。此时需要使用加工助剂,其目的是提高塑化质量,提高CPVC功率管材料的低温冲击性能和成品的耐受性。对于PVC空心缠绕管,树脂颗粒间的相互作用差,传热差,易发生熔体分裂,塑化质量差。
  Extrusion and injection processing of PVC hollow winding pipe, processing aids the effect of PVC power pipe on plasticizing quality. At this time, processing aids are needed to improve the plasticizing quality, the low-temperature impact performance of CPVC power pipe material and the tolerance of the finished product. For PVC hollow wound pipe, the interaction between resin particles is poor, the heat transfer is poor, the melt splitting is easy to occur, and the plasticizing quality is poor.
