摘要

以小径级杉木六棱柱体锯制的层板为芯层和底层,并在芯层内置碳纤维电热线,制备三层结构地热地板,测试在不同电压下地板的导热性能和尺寸稳定性。结果表明:试板经0.5h左右即达到平衡温度,最终可达30,3,5℃,表面温度分布均匀,电压的提高有助于地板的导热效能,并能够显著提高地板最终平衡温度;组坯方式对地板面层温度及尺寸稳定性均无明显影响,但对传热稳定性有一定影响;长时间加热时地板的尺寸稳定性有待提高。

Abstract

The authors developed a new kind of electrically heated flooring using hexagon glulam made with small-diameter Chinese fir as the core and base the layers with carbon fiber electric heating wires laid between the layers.Heat conductivity and dimensional stability of the flooring were tested.The results showed that the carbon fiber electric heating wires were effective.The peak temperature of the samples could reach 30,3,5 ℃ in 30 minutes with good temperature uniformity.A higher voltage could increase the peak temperature of the flooring.The flooring assembly method had little effect on the surface temperature and dimensional stability but could affect heat transfer stability.
