近年来,电力部的有关单位研制的泡沫石棉毡和微孔硅酸钙制品两种新型保温材料,经有关工程试点使用获得了初步成功。1979年6月,电力部电力建设研究所在上海召开了保温材料革新经验交流会议,对上述两种保温材料进行了评定。湿法生产的泡沫石棉毡是一种超轻质保温材料,具有呈网络状的气孔结构,因此,它比石棉具有容重轻、保温和抗震性好、便于运输及施工等优点。这种泡沫石棉毡采用温石棉、 In recent years, two new types of insulation materials, foamed asbestos mats and microporous calcium silicate products developed by the relevant units of the Ministry of Electric Power, have achieved initial success through the pilot project. In June 1979, the Electric Power Construction Research Institute of the Ministry of Electric Power held an exchange meeting on the innovation of insulation materials in Shanghai and evaluated the above two types of insulation materials. Wet-processed foam asbestos mat is an ultra-lightweight thermal insulation material with a network-like pore structure. Therefore, it has the advantages of lighter weight density, better thermal insulation and shock resistance, and easier transportation and construction than asbestos. This foam asbestos blanket uses chrysotile,
