摘要

为了开拓稻秆的利用途径,以不同长度的稻秆为原料制备墙体保温材料,研究秸秆长度对保温材料力学性能和导热性能的影响。结果表明:稻秆越长,保温材料的力学性能越强;稻秆长度对保温材料性能有明显影响。随着环境温度的升高,材料的导热性能呈下降趋势。与目前市场上常见的墙体保温材料相比,其具有能耗低、环保等优势。

Abstract

The rice straw were chopped into different lengths of 4,6,8 and 10cm respectively and then used the same length of straw for manufacturing insulation boards by hot pressing.The effect of rice straw length of board on mechanical property and thermal conductivity of the samples was investigated.The results showed that the mechanical property of the samples improved with increased rice straw length,the thermal conductivity of the samples tested under different ambient temperatures increased with increased ambient temperature,the length of rice straw had significant effect on thermal conductivity of the boards.
