人造夹芯板与泡沫塑料导热率的对比研究

The Contrast of Wood-based Panel and Foam by Thermal Conductivity

目前低密度纤维板具有较好的机械性,而导热率是保温材料性能的重要指标之一。试验中测得密度为340kg/m3(WBP340)与410kg/m3(WBP410)的导热率分别是0.070W/(m.K)和0.077W/(m.K)。对比其他常用保温材料,低密度的纤维板的导热率特性优于实木,稍逊于泡沫塑料。考虑环保因素,低密度纤维板作为建筑保温材料有较高的实用意义。

Currently, low density fiberboard has good mechanical, and it can be used as building walls and floor insulation. Thermal conductivity of insulation materials is one important indicator of performance. In this experiment, we measured wood-basedpanel,sthermalconductivitywiththedensityof340kg/m^3 （WBP340）and410kg/m^3 （WBP410）.Theresultwere 0.070W/ （ m· K） and 0.077W/ （m·K ） respectively. Compared to other common insulation materials, such as foam material, thermal conductivity of wood-based panel was lower. Considering together with the environmental factors, wood-based panel has high practical significance as building insulation.
