【摘要】 对销钉机筒挤出机生产过程中的挤出温度、单位体积能耗、胶料粘度及机头压力等工艺参数进行回归分析,得到工艺参数的回归方程。显著性检验表明回归得到的因数和方程是高度显著的。回归分析结果表明,对挤出温度的相关程度由大到小依次为挤出段加热温度、机头段加热温度、螺杆加热温度、塑化段加热温度、螺杆转速和口型大小。回归方程除可用于确定挤出工艺参数外,还可预测单位体积能耗和挤出胶料温度。更多还原

【Abstract】 The parameters such as the extruding temperature,energy consumption per unit volume,viscosity and die pressure for pin barrel extruder during production process were studied.Through the regression analysis of the experimental data,the significance test showed that the regression equations obtained were highly significant.The results indicated that the correlation degree with the extruding temperature gradually decreased in the following order:extruding zone heating temperature,die zone heating temperature,screw heating temperature,plasticizing zone heating temperature,screw rotate speed and die size.The regression equations could be used in guiding the extruding techniques,the forecast of the energy consumption per unit volume and the extruding temperature of compound.更多还原
