摘　　要：离心保温棉因其优越的保温性能，被广泛应用于建筑节能体系中。本文通过实验研究了离心保温棉的吸湿特性及湿传递性能。吸湿特性实验研究了离心保温棉的等温吸湿曲线，并给出了离心保温棉平衡含湿量随相对湿度变化的拟合公式；湿传递性能实验研究了离心保温棉的水蒸气渗透系数，将实验数据进行最小二乘法拟合，得到的拟合公式适用于相对湿度区问为0-100％。以上研究结果为离心保温棉的研究与应用提供理论基础和计算依据。An experimental study was made of hygroscopic properties and moisture transfer performance of centrifugal insulation cotton. As to hygroscopic properties, the isothermal moisture of centrifugal insulation cotton was studied and the fitting formula of equilibrium moisture varying with the relative humidity was given; as to moisture transfer performance, an experimental study of centrifugal insulation cotton vapor permeability coefficient was made, as well as the least squares fit based on experimental data. The fitting formula obtained applied to a relative humidity ranging from 0 to 100%.
