Insulating materials made from straw are becoming increasingly popular in the construction industry. Straw can be used in the construction of buildings as uncompressed straw chips or in the form of compressed panels. This study aimed to determine the possibility of manufacturing boards from straw particles with densities in the range of 150-400 kg/m, allowing favorable mechanical properties while simultaneously providing high thermal and acoustic insulation properties. The study also analyzed the influence of the degree of carpentry density on the quality of the manufactured boards. The study shows that insulation boards can be produced from straw particles with satisfactory properties already at densities in the range of 200-150 kg/m. Boards with this density have a compressive strength of 150 kPa, thermal resistance of 0.033-0.046 W/(m·K), and a sound absorption coefficient above 0.31.
由稻草制成的绝缘材料在建筑行业中越来越受欢迎。稻草可作为未压缩的稻草碎片或压缩板的形式用于建筑物的建造。本研究旨在确定制造密度在150 - 400 kg/m范围内的稻草颗粒板的可能性，使其具有良好的机械性能，同时提供高隔热和隔音性能。该研究还分析了木工密度程度对制成板材质量的影响。研究表明，在200 - 150 kg/m的密度范围内，就可以用稻草颗粒生产出性能令人满意的绝缘板。这种密度的板材抗压强度为150 kPa，热阻为0.033 - 0.046 W/(m·K)，吸声系数高于0.31。
