摘要
涂料涂覆在建筑物的外表面受环境的影响,易被污染而改变涂料本身的太阳光吸收系数,从而影响节能效果。比较外墙反射隔热涂料使用1年后与新涂料的实测数据,结果显示,污染后的热反射隔热涂料反射隔热性能有所降低,但仍比普通涂料具有较好的隔热性能,延迟时间也相对新涂料缩短0.2h。在实际建筑节能研究中,应取污染后的反射隔热涂料节能效果进行评价。
Under environmental influences, coating on building surface may be easily contaminated and its sunlight absorption coefficient may be changed to affect its energy saving effect. After comparison and analysis of tested data between the heat reflection insulation coating on the external wall of testing building and new coating, it is found that the heat reflection insulation performance of contaminated coating will be weakened but still be better than ordinary coating, and that the heat retardation of contaminated coating is also 0.2 h shorter than new coating. During research on building energy saving performance, the energy-saving effect shall be determined according to the contaminated healt reflection insulation coating.
