摘要
本文实测了锯末、谷糠、花生壳等几种农林加工"废弃物"以及保温砂浆颗粒的导热系数,比较了几种生物质材料、复合保温材料与石化保温材料的导热系数等热工特性,讨论了生物质材料用于中国农村建筑保温隔热的方法及节能减排潜力.中国是个农业大国,在农村建筑保温节能中因地制宜使用生物质材料,效益显著,潜力巨大.
The thermal conductivities of a thermal insulation mortar particle and several processing wastes,such as sawdust,bran,peanut hull,were measured.The thermal conductivities were compared between several biomass,composite and petrochemical materials.The application means and energy saving potential were also discussed while biomass materials were utilized for thermal insulation of building envelope in rural buildings in China.China is a large agricultural country,application of biomass materials should be adapted to local conditions,and the benefit can be remarkable,the potential can be great in thermal insulation and energy conservation in rural buildings.
