摘要

在单因素实验的基础上，根据Box-Behnken实验设计原理，采用响应面分析方法建立了数学模型。研究了热压温度、热压时间和热压压力三个因素及其相互作用对水杉基三层结构镶木地板断裂模量的影响。结果表明，回归方程中的二次多项式模型具有显著性，模型预测值与实验值的相关性为91.17%。确定了最佳热压工艺参数为：热压温度96.03°C，热压时间6.70min，热压压力8kg·cm-2。在这些条件下，获得了最佳MOR，达到102.05MPa。理论预测值与实验结果吻合较好。

OPTIMIZATION OF THE MANUFACTURING OF METASEQUOIA-BASED THREE-LAYER STRUCTURE PARQUET FLOORING BY A RESPONSE SURFACE METHODOLOGY

On the basis of a single-factor experiment, a mathematical model was established by the response surface analysis method based on the Box-Behnken experimental design principle. The effects of three factors, including hot-pressing temperature, hot-pressing time, and hot-pressing pressure, and their interactions on the modulus of rupture (MOR) of Metasequoia-based three-layered structure parquet flooring were studied. The results show that the quadratic polynomial model in the regression equation is significant, and the correlation between the value predicted by the model and the experimental value is 91.17%. The optimized best hot-pressing process parameters are determined to be as follows: hot-pressing temperature of 96.03°C, hot-pressing time of 6.70 min, and hot-pressing pressure of 8 kg·cm-2. Under these conditions, the best MOR are obtained, reaching a value of 102.05 MPa. The theoretically predicted value is in good agreement with the experimental results.
