建筑节能用岩棉性能的研究
The properties research of the rock wool used for energy saving
【摘要】 根据国内外相关规范测试了4种不同规格岩棉的导热系数、抗拉强度、24 h与28 d部分浸泡的吸水量、潮湿环境中的强度保留率等宏观物理力学性能,分析得出岩棉性能在外界条件改变下的变化规律。试验测试结果表明,所测岩棉的各项性能指标均符合EN13500、EN13162及ETAG004规范的要求。并提出了岩棉作为外墙外保温材料应注意的事项,可为工程应用提供一定的理论依据。
【Abstract】 According to the domestic and foreign related standards,we tested the thermal conductivity,tensile strength,shortterm(24 h) part soaking water absorbing capacity,long-term(28 d) part soaking water quantity and strength retention in damp condition of 4 kinds of rock wool.Through the analysis of the physical and mechanical properties,we obtained the rock wool’s performance change rule with the change of the external conditions.The conclusion shows that the various performance indicators of rock wool are all in line with EN13500,EN13162 and ETAG004’s requirements.So this paper puts forward the notes when the rock wool is used in the exterior insulation system.What’s more,it also provides some certain theoretical basis for the engineering practice.
