某些多年传承的经验有经聚氨酯保温管是以高功能聚醚多元醇组合料和多次多多异氰酸酯为原料经化学反应发泡而成。聚氨酯保温管用于室内外各种管道,集中供热管道,空调管道、化工、等工业管道的保温、保冷工程。概述 聚氨酯发泡保温管自三十年代聚氨酯合成材料诞生以来,一直作为一种优良的绝热保温材料而得到迅速发展,其应用范围也越来越广泛,更由于其施工简便、节能防腐效果显著而被大量地用于各种供热、制冷、输油、输汽等各种管道。聚氨酯保温管从里到外分三层结构:不起推敲的方面,在一定程度上造成了较大的资源耗费。基于这些原因,本人从2006年起对上述问题进行了针对性的试验,对某些数据一旦改变后其他相应数据随之变化的现象进行对比分析,力图找出有规律的量与量的变化关系。经过多次试验,发现一些单位用提高补水压力的方式来加大供水压力,以求改善运行状况的方法不但达不到理想效果,反而会增加无谓开支,消耗更多的能量。本人的试验得出了这样一个结论:即用提高补水压力的方法提高管网运行压力会增加循环阻力,从而降低供回压差,补水压力对管网水的循环有不容忽视的阻碍作用。
