| 摘 要： | 针对湿热地区潮湿气候作用下建筑保温砂浆受潮的规律,采用天平称重法对玻化微珠保温砂浆进行了自然状态吸放湿实验,并采用热湿气候风洞实验法对其质量平衡含湿率进行测定,进而采用平板法对其湿平衡状态下的导热系数进行了一系列测试分析。结果表明,在南方地区潮湿气候条件下玻化微珠保温砂浆质量平衡含湿率约为3.55%;湿平衡状态下玻化微珠保温砂浆导热系数修正系数在1.04~1.11之间,平均值为1.08,考虑受潮现象的复杂性,建议在实际建筑工程节能设计时,该修正系数宜取1.10。

| Abstract: | Based on the raw of moisture absorption under humid environment in hot humid area, the balance method was adopted to measure the moisture absorption and desorption curve of thermal insulation glazed hollow bead motar in the natural condition. And wind tunnel hot humid climatic was adopted to measure its moisture content of quality equilibrium. And then guarded hot plate apparatus was employed to measure and analyze its thermal conductivity in moisture equilibrium condition. It is found that : 1) the moisture content of quality equilibrium of thermal insulation glazed hollow bead motar under humid climate in southern area is about 3.55%; 2) under the moisture equilibrium condition, the correction factor for thermal conductivity of thermal insulation glazed hollow bead motar is from 1.04 to 1.11 and with the mean of 1.08, and it is recommended to be 1.10 considering the complexity of moisture absorption during the process of building energy efficiency design for practical projects. |
