摘　　要：为探讨自制复合调湿材料替代温室后墙体内表面部分红砖的可行性,对密闭空间内的复合调湿材料进行了调湿能力研究,同时,在室温条件下对其进行了热工和力学性能的试验研究。结果表明:密闭空间的复合调湿材料其饱和吸湿率可达130%;在40min内,相对湿度降低了23%,即相对湿度由92.5%降低到了69.5%,在13h内相对湿度降低到了30.5%,即由92.5%降低到62%,在高湿情况下吸湿的性能要高于硅胶,吸湿性能比较显著;复合调湿砌块能够满足温室内墙体材料的热工性能和机械性能的要求。In order to investigate the feasibility that self-made composite humidity-controlling materials replace the fraction red brick of the internal surface of back wall in greenhouse,a study on the humidity-controlling ability of composite humidity-controlling materials in confined space was conducted.At the same time,thermal and mechanical properties of composite humidity-controlled material were investigated in room temperature.The results showed that： saturated moisture absorption rate of composite humidity-controlled could be approximately 130%;in 40 minutes,the relative humidity decreased by 23%,which meant that the relative humidity decreased from 92.5% to 69.5%,the relative humidity decreased to 30.5% in 13 hours,which meant the relative humidity decreased from 92.5% to 62%.Under higher humidity conditions,the moisture-absorbing ability of the composite humidity-controlled materials was higher than that of silicone,having a more significant moisture absorption performance.The composite humidity-controlled building block could satisfy the thermal and mechanical property requirement of wall materials in greenhouse.
