在给排水、采暖及空调管道的安装过程中,为减少热损失或防结露,管道须进行保温隔热处理,但其中的套管处保温处理很少引起重视,大部分填塞油麻或石棉水泥,部分甚至不处理,起不到保温隔热作用,不仅造成能量损失,冷水管道还会出现管道结露导致冷凝水污染顶棚和墙面的问题。究其原因,一是节能意识不够,认为此处保温无关紧要;二是此处的处理难度颇大。若采用PU聚氨酯发泡填充的方法进行保温,相比聚苯颗粒等保温材料,其具有较
In the installation of water supply and drainage, heating and air-conditioning pipelines, in order to reduce heat loss or prevent condensation, the pipe must be heat-insulated and heat-insulated, but the insulation at the bushing is seldom taken seriously. Most of the pipes are filled with linseed or asbestos Cement, some do not even deal with, can not play the role of thermal insulation, not only cause energy loss, cold water pipes will also lead to dew condensation pipe condensation and water pollution ceiling and wall problems. The reason, first, awareness of energy conservation is not enough, that insulation does not matter here; the second is the treatment here is quite difficult. If using polyurethane foam filling method of insulation, compared to polystyrene particles and other insulation materials, which have more
