陶瓷材料低温挤压自由成形工艺液相迁移研究
|
摘要
利用正交试验法,研究了挤压工艺参数对水基陶瓷膏体低温挤压成形过程中挤出膏体的液相含量的影响。正交试验中选择挤压速度、挤出喷嘴长度及挤出间隔时间作为试验因素,挤出膏体中的液相含量作为评价指标。试验数据的极差和方差分析结果表明:液相迁移随挤出速度增大而减小,随挤出喷嘴长度的增加和间隔时间的延长而增大;各因素影响液相迁移的显著性参数依次为挤压速度>挤出喷嘴长度>挤出间隔时间。同时,建立挤出膏体中液相含量与工艺参数之间的回归预测模型。通过对比试验结果和模型计算结果发现:在本试验条件下,预测结果与试验结果的相对误差为1.410%,可对挤压过程中的液相迁移进行预测。
Influences of extrusion parameters on liquid content of extrudate for freeze-form extrusion fabrication of aqueous ceramic pastes were analyzed by the orthogonal test.In the test,extrusion parameters including the extrusion velocity,the extrusion nozzle length,the extrusion interval time were examined,while the liquid content of extrudate was used as the evaluation index of extrusion process.The analysis of range and variance of test data indicates that liquid phase migration during extrusion process becomes large with the increasing of the extrusion interval time and the extrusion nozzle length,and the decreasing of the extrusion velocity.The significance order of factors are as follows:the extrusion velocity>the extrusion nozzle length>the extrusion interval time.At the same time,the prediction model between the liquid content in extrudate and the parameters was established.By comparing the results of orthogonal experiment and prediction model calculation,it can be inferred that the relative error between the value of the prediction model calculated and the experiment measured is 1.410% under the test condition,the prediction model could be used to predict the liquid migration in extrusion process.
