来源:http://www.sdhpgy.com 日期:2019-11-26 发布人:admin
  聚氨酯保温钢管是重要的应用管道,对于能源、供热等有至关重要的作用,所以它的质量要求格外严格。在出厂前是必须进行检测的,检测内容主要包含钢管规格、钢管材质、保温层厚度等内容。
  Polyurethane insulated steel pipe is an important application pipe, which plays an important role in energy and heat supply, so its quality requirements are particularly strict. Before leaving the factory, it must be tested, which mainly includes steel pipe specification, steel pipe material, insulation layer thickness, etc.

  就目前安装情况来说,聚氨酯保温钢管不需要专门的地沟,直接埋入土中就可以,保温和防腐效果是其他管道不能比拟的,此外哦,聚氨酯保温钢管由于保温效果突出还具备一定的节能作用,同样的管道,保温效果好可以降低输送过程中的热损失达到节能目的。
  As far as the current installation situation is concerned, polyurethane insulated steel pipe does not need a special trench, but can be directly buried in the soil. The insulation and anti-corrosion effects are incomparable with other pipes. In addition, polyurethane insulated steel pipe has a certain energy-saving effect due to its outstanding insulation effect. For the same kind of pipes, good insulation effect can reduce the heat loss in the transportation process to achieve the purpose of energy conservation.
  根据相关部门的测算以及实际使用情况,1公里聚氨酯保温钢管管道相比其他管道每年可以节省燃煤10吨左如果全部供暖管道都是用聚氨酯保温钢管的话,每年可以节省大量的燃煤,不仅节省了费用还保护了环境。
  According to the calculation and actual use of relevant departments, 1 km polyurethane insulated steel pipe can save 10 tons of coal annually compared with other pipes. If all heating pipes are polyurethane insulated steel pipes, a large amount of coal can be saved every year, which not only saves the cost but also protects the environment.

  聚氨酯保温钢管对于生产环境的要求
  Requirements of polyurethane insulated steel pipe for production environment
  1. 风力因素: 喷涂作业时,要求风速在 5m /s 以下。因为风速超过 5m /s ,将吹失反应产生的热量,以致影响聚氨酯泡沫快速发泡反应,使产品表面变脆。同时,由于喷涂发泡机将原料混合好后,以雾化状态喷出,如风速过大,将会吹走雾化颗粒,增大原料损耗,污染环境。
  1. Wind factor: when spraying, the wind speed is required to be less than 5m / s. Because the wind speed exceeds 5m /s, the heat generated by the reaction will be lost, which will affect the rapid foaming reaction of the polyurethane foam and make the surface of the product brittle. At the same time, because the spray foaming machine will mix the raw materials and spray them out in the atomized state, if the wind speed is too high, the atomized particles will be blown away, the loss of raw materials will be increased, and the environment will be polluted.
  2.温度因素: 喷涂时,现场环境温度和待喷基材表面温度范围应该在 15 ℃ ~ 35 ℃ 。如果温度过低,聚氨酯泡沫和基材的粘接力就会降低,且喷涂硬泡产品的密度就会明显增大;如果温度过高,发泡剂损耗太大,不经济。
  2. Temperature factor: during spraying, the field ambient temperature and the surface temperature of the substrate to be sprayed shall be within 15 ℃ ~ 35 ℃. If the temperature is too low, the adhesion between polyurethane foam and base material will be reduced, and the density of the product will increase obviously. If the temperature is too high, the foaming agent will lose too much and is not economical.

  3.基材表面因素: 聚氨酯硬质泡沫是异氰酸酯和组合聚醚双组分混合反应生成的高分子产品,其中异氰酸酯组分很容易和水反应生成脲,如果聚氨酯中脲键含量升高,则泡沫塑料将变脆,泡沫与基材的粘接力降低。因此,要求待喷基材表面清洁干燥,要求无锈、无粉尘、无污染、无潮气。若有露水或霜,应予以去除和干燥。
  3. substrate surface factors: polyurethane rigid foam is a polymer product produced by mixed reaction of isocyanate and combined polyether, and the isocyanate component is easily reacted with water to form urea. If the content of urea bond in polyurethane increases, then the foamed plastics will become crisp and the adhesion between foam and substrate will be reduced. Therefore, the surface of the substrate to be sprayed shall be clean and dry, without rust, dust, pollution and moisture. If there is dew or frost, it should be removed and dried.
  聚氨酯发泡保温管道道在施工的时候有些情况是不能逆转的,在安装聚氨酯发泡保温管道的时候要使用正确的方法,有一点不对的话就不能将他的功能很好的展现出来,所以多余管道保温技术来说,他在以后的发展趋势上进行分析,更能够对国内的经济带来很大的影响。
  In the construction of polyurethane foam insulation pipeline, some situations can not be reversed. When installing polyurethane foam insulation pipeline, the correct method should be used. If there is one mistake, it can not show its function well. So in terms of redundant pipeline insulation technology, it can bring a lot to the domestic economy by analyzing its development trend in the future Influence.
