| 摘 要： | 本文研究了川西两种磷石膏(白、黑各一种)的保温、调湿功能属性.其导热系数分别为0.1213 W/m·K、0.2211 W/m·K;密闭条件下饱和吸水时间随温度升高而变短,且成线性关系.磷石膏的吸水率随温度的上升而增大,此过程是一个吸热和熵增的过程.常温敞开条件下,磷石膏在白天温度高湿度低时放水,晚上温度低湿度高时吸水,具有一定的调湿功能.应用差示扫描量热分析法(DSC)对磷石膏进行了试验分析,结果表明其吸热量随温度升高而减少.

| Abstract: | The functional attributes of thermal insulation and humidity conditioning of two kinds of phosphogypsum(white and black) from the west Sichuan were studied in this paper.The thermal conductivity are 0.1213 W/m.K and 0.2211W/m.K respectively;the saturated adsorption time to water gets shorter with rising of temperature in closed conditions with a linear relation.The water absorption of phosphogypsum increases with rising of temperature,and this process goes with heat absorption and entropy production.Under t... |
