支撑HDPE钢带增强聚乙烯管发展的几大因素!

  为什么近年来HDPE钢带增强聚乙烯管能占全国的一半?主要原因是PE的整个配套产业链是最完善的,以及国内原材料的配套。PE树脂原料是由单体乙烯聚合而成,由于不同的压力、温度等聚合反应条件,可以得到不同密度的树脂,所以有高密度聚乙烯、中密度聚乙烯和低密度聚乙烯。在加工不同类型的HDPE管时,根据不同的应用条件,选用不同的树脂牌号,同时对挤出机和模具的要求也不同。并且生产的HDPE钢带增强聚乙烯管材能满足以下质量过关要求:
  Why in recent years HDPE steel band reinforced polyethylene pipe can account for half of the country? The main reason is that the whole supporting industry chain of PE is the most perfect, as well as the matching of domestic raw materials. PE resin raw material is polymerized by monomer ethylene. Due to different pressure and temperature, different densities of resin can be obtained, so there are high density polyethylene, medium density polyethylene and low density polyethylene. When processing different types of HDPE pipes, different resin grades are selected according to different application conditions, and the requirements for extruders and dies are also different. And the HDPE steel strip reinforced polyethylene pipe can meet the following quality requirements:
  1. 安全性和可靠性。
  1. Safety and reliability.
  这是最重要的原则,管道应能承受振动冲击、水击和热胀冷缩,并能经受时间的考验,无泄漏,无爆裂。
  This is the most important principle. Pipelines should be able to withstand vibration shock, water hammer, thermal expansion and contraction, and can withstand the test of time, no leakage, no burst.
  2. 卫生。
  2. hygiene.
  显然,目前投放市场的所有管材都要符合国家标准CJ/ t225-2011的要求,只有经过国家认可的检测部门检测后才能投放市场。

  Obviously, all pipes put into the market at present must meet the requirements of the national standard CJ / T225 - 2011. Only after testing by the national recognized inspection department can they be put into the market.
  3.节能。
  3. energy saving.
  任何钢管从原材料的提取和合成、熔炼镉、轧制、注塑挤出等方面的能耗,从宏观上看,金属管比HDPE钢带增强聚乙烯管的能耗要高。在复合工艺中,采用热膨胀喷涂技术的钢塑复合管材比金属管能耗高,厚壁管材比薄壁管材能耗低。
  The energy consumption of any steel pipe from the extraction and synthesis of raw materials, cadmium smelting, rolling, injection extrusion and other aspects is higher than that of HDPE steel strip reinforced polyethylene pipe from the macro point of view. In the composite process, the energy consumption of steel-plastic composite pipes with thermal expansion spraying technology is higher than that of metal pipes, and the energy consumption of thick-walled pipes is lower than that of thin-walled pipes.
  经济。
  Economics.
  在保证使用安全的前提下,选用成本最低的HDPE通用增强网状结构壁管。管材价格比较时,管件价格比较均匀,施工安装成本比较均匀。
  On the premise of ensuring safe operation, the lowest cost HDPE steel strip reinforced polyethylene pipe was selected. When comparing the price of pipe materials, the price of pipe fittings is relatively uniform, and the cost of construction and installation is relatively uniform.
