摘要: 运用振实密度法测试粉末竹炭的密度,采用Box-Behnken响应曲面法,以粉末竹炭的颗粒度(目数)、振实仪的转速和振动次数作为考察因子,竹炭密度作为响应值建立二次数学模型,分析各因素及其交互作用对密度的影响。结果表明:在模型条件下,竹炭密度测试最优参数为粉末竹炭颗粒度120~160目、转速200 r·min-1和振动次数1 000次,预测密度为0.498 g·cm-3,验证实验平均结果为0.483 g·cm-3,与预测值偏差为0.015。Abstract: The density of powdered bamboo charcoal was measured by vibrating density method. The box Behnken response surface method was used to establish a quadratic mathematical model to analyze the influence of various factors and their interaction on density, in which, the particle size (mesh) of powdered bamboo charcoal, the rotation speed and vibration times of vibrating instrument were taken as investigation factors, and the density of bamboo charcoal was taken as response value. The results showed that under the model conditions, the optimal parameters of bamboo charcoal density test were as follows:powdered bamboo charcoal particle size 120-160 mesh, rotation speed 200 r·min-1 and vibration frequency 1 000 times, the predicted density was 0.498 g·cm-3, the average result of validation experiment was 0.483 g·cm-3, and the deviation from the predicted value was 0.015.
