【摘要】 考察了凹凸棒石内孔结构对吸放湿能力的影响,对不同相对湿度下凹凸棒石的吸放湿性能进行了研究。在此基础上,制备了凹凸棒石改性的水泥基复合材料,考察了凹凸棒石对复合材料内部结构及调湿性能的影响。结果表明:凹凸棒石改性的水泥基复合材料能使环境相对湿度保持在40%~60%,具备优异的自调节湿度功能。更多还原

【Abstract】 On the basis of the influence of the inner pore structure of attapulgite on its moisture absorption/disabsorption characteristics, experiments were made under different relative humidity. According to this ground, the cement-based composite material modifi ed by attapulgite was made, and the influence of attapulgite on the inner structure and humidity controlling characteristic of composite material was studied. It was shown that the cement based composite material can keep the surroundings relative humidity in a range of 40%~60%, and owned great ability of self-humidity control.更多还原
