Abstract:
In order to clarify the humidity conditioning rule of interior decorative materials during the changing process of water vapor round the materials and evaluate quantitatively their humidity conditioning properties, the curves of the relative humidity in the experimental box lined with wood, wood based or inorganic materials were determined by changing the content of water vapor at an ambient temperature of 26 ℃.Two physical quantities x and y were defined to represent the humidity conditioning properties of these materials.The results showed that the various interior materials can be classified into four groups according to their x and y values; wood or wood-based materials can condition environmental humidity very well; the values of x and y of wood-based materials decrease as the increasing of the values of A/ V; and during the cyclic changing of the content of water vapor in this experiment, the influence of specimen's thickness on humidity conditioning property is not obvious.
Key words: Interior decorative materials, Environmental humidity, Humidity conditioning function
