摘要:
在评述现有关于调湿材料的调湿特性指标的基础上,利用热力学基本原理,从两相平衡的角度导出封闭空间调湿特性指标值的表达式,并对其进行分析说明 .发现 B值仅是基于调节的目标状态温度为零度而存在的,用于非零度的调节目标时会产生较大误差 .就 B值的不足,提出新的调湿特性指标 BT值 .BT值是基于所调节的目标状态而导出的,较 B值更为合理准确 .B值和BT值都反映材料与水分的结合性质,与结合能密切相关 .材料与水分的结合能越接近纯态水分子间结合能,材料的调湿特性越好 .
Abstract:
The present work is based on a commentary on the characteristic index of the humidity controlling material now available. By applying the basic principle of thermodynamics, the expression of characteristic index B to the humidity control in a closed space is derived and is analysed and explained from the angle of two phase equilibrium. In respect to the inadequacy of B value, a new characteristic index BT to the humidity control is advanced. As indicated by theoretical analysis, the existing B value is based on that the initial state equals to 0℃; while BT value is derived on the basis of the target state of adijustment and is thus even more reasonable. Both B and BT reflect the combinability of material and water, which is closely related to the binding energy. the more close of the binding energy of water and material to the intermolecular binding energy of pure liquid state water. the better the humidity controlling characteristic of the material.
