【摘要】 为研究含水率对草坪草常温成型的影响规律,对草坪草修剪剩余物进行了不同含水率不同锥度模具的成型试验。结果在同一锥度模具下,随着含水率的增加,成型块密度都是由小变大再变小;含水率不变的情况下,随模具锥度增大长度减小成型块密度降低;在原料含水率11%、模具锥度25°时,成型块密度达到最大值1.10g/cm~3;原料含水率在20%及以上时,挤出的压块密度都在0.9g/cm~3以下,成型效果差或不成型。研究表明:随着生物质原料含水率增加,常温成型块密度和压缩力的变化趋势一致,都是由小变大再变小。更多还原

【Abstract】 In order to study the influence of moisture content on biomass room-temperature forming,forming tests on turfgrass were done in different moisture content and taper with forming bench.The results indicates that density of block varies from small to big firstly,and then to small,accompanying with the increase of moisture content in the same taper;Under a certain moisture content,the density decreases with taper increasing;when moisture content is at 11%and mold taper is at 25°,the density of block reaches max-1.10 g/cm~3;When raw material moisture content is at 20%or above,the density of lawn grass is smaller than 0.9 g/cm~3.The results show that the density and pressure of biomass have the same trend which is from small to peak and then to bottom with the increase of water content.更多还原
