传统保温材料与新型保温材料对比及选用原则
|
摘要
国内高温管道系统表面热损失超标具有普遍性,正确认识及选取保温材料是确保绝热工程质量的前提。通过分析高温管道保温现状,详细介绍了两类传统保温材料:复合硅酸盐(主要种类有硅酸镁、硅酸铝、稀土复合保温材料),纤维类(岩棉、玻璃棉、硅酸铝纤维等);及两类应用趋广的新型保温材料:CAS铝镁质保温材料、纳米保温材料的物理组成、绝热性能及平均使用寿命。并在此基础上,给出了5条保温材料基本选用原则。
It is universal that the surface heat loss of domestic high temperature pipeline system exceeds the standard. Correct understanding and selection of insulation materials are the premise to ensure the quality of insulation engineering. By analyzing the present situation of high temperature pipeline insulation,two kinds of traditional insulation materials are introduced in detail: composite silicate( mainly magnesium silicate,aluminium silicate,rare earth composite insulation materials),fibers( rock wool,glass wool,aluminium silicate fiber,etc.) and two kinds of new insulation materials which are widely used: CAS aluminium-magnesium insulation materials and CAS aluminium-magnesium insulation materials. The physical composition, thermal insulation and average service life of nano insulation materials. On this basis,5 basic principles for selecting insulation materials are given.
