摘　　要：湿度是评价室内环境舒适程度的重要指标之一。调湿材料依靠自身的吸放湿性能,根据环境相对湿度的变化自动调节空气中的水分含量。纸面石膏板具有质轻、高孔隙率、优良的吸附性能、绿色环保等优点,是理想的调湿材料之一。对常规建筑围护材料的调湿性能进行了监测,尤其是对纸面石膏板的调湿性能进行了探索研究。通过测试发现,在冬冷夏热的北京7、8月份,特定条件下装有纸面石膏板围护结构的室内环境相对湿度比室外相对湿度降低了2~8个百分点。Humidity is one of significant factors to evaluate comfort of interior air environment.Humidity control material can regulate moisture content of interior air automatically according to the vary of relative humidity with moisture adsorption/desorption ability.Due to light weight,high porosity,excellent absorption capacity and green initiative,plasterboard is an ideal material for humidity control.In this article,we studied the humidity control performance about plasterboard and other building envelope materials.Through testing,it is found that in July and August in Beijing,which is cold in winter and hot in summer,the relative humidity of the indoor environment with plasterboard all around the wall under certain conditions could be 2~8 percentage points lower than that of the outdoor environment.
