摘要
为了弄清楚在温度变化过程中木质室内装饰材料对环境湿度的调节功能及其规律，本研究采用外型尺寸为２０ｃｍ×２０ｃｍ×３０ｃｍ的不锈钢封闭箱体，在箱体的内表面分别饰以木质和非木质材料。调控箱体外温度在２０℃～３３℃范围内变化，测定了封闭箱体内环境温度Ｔ、相对湿度Ｈ和绝对湿度的对数ｌｏｇｈ随时间的变化情况。结果表明，ｌｏｇｈ和Ｔ之间存在着相关性十分高的线性关系，用其关系曲线的斜率ｂ值能够评价材料的调湿性能。按材料调湿性能参数ｂ值的大小，本研究对胶合板、刨花板、纤维板、瓷砖、壁纸和聚胺酯饰面椴木三合板等多种材料作了湿度性能区分。椴木三合板的ｂ值随着气积比Ａ／Ｖ的增大呈曲线上升趋势。聚胺酯饰面椴木三合板的ｂ值比未饰面时降低了２／３左右。在温度上升初期阶段，木质材料和非木质材料的环境湿度的变化趋势是截然相反的。
In order to clarify the rules of humidity conditioning function of interior wall materials,the temperature,relative humidity and logarithm of absolute humidity in a box (20cm×20cm×30cm),which was constructed of steel plates and lined with an experimental material on its floor,were measured at a certain time when its ambient temperature was changed from 20℃ to 33℃.The experiments showed that the logarithm of h was represented approximately by a linear equation of temperature T ,and the degree of humidity conditions could be evaluated by the slope (b) of the equation.The b values were used to classify the tested interior wall materials such as plywood,particleboard,fiberboard and so on.The value b of linden plywood tended to increase nonlinearly with the increasing ratio of the area (A) occupied by the wall material to the volume ( V ) of the steel box (A/V ).The value b of linden plywood covered with polyurethane coating was about 2/3 of the uncovered.At the beginning of the rise of the ambient temperature,the different changing tendency of relative humidity was observed between wood based materials and synthetic of inorganic ones. \ \
