插层熔喷非织造材料的性能控制研究

Study on Property Control of Intercalated Melt-Blown Nonwovens

摘要: 本文在插层率固定的情况下，研究不同工艺参数组合的插层熔喷非织造材料的结构变量和产品性能。通过变量的调式建立最优化的多项式拟合模型，代入预处理后的数据，得到工艺参数与结构变量之间的关系，并通过数据可视化和三维拟合图使结果更直观。对经过雅克–贝拉检验后的数据使用样本皮尔逊相关系数法，再辅以蒙特卡罗法和非线性规划模型求解出何时过滤效率的最优解。在满足实际生产条件的基础上，通过使用消除量纲且被转化为最大化变量后的数据，将其代入加权组合降维后的单目标规划模型，得到结构参数的组合使得过滤效率尽可能大的同时过滤阻力尽可能的小。

Abstract: In this paper, the structural variables and product properties of intercalated melt-blown nonwovens with different combination of process parameters are studied under the condition of fixed intercalation rate. The optimized polynomial fitting model was established through the varia-ble mode, and the relationship between process parameters and structural variables was obtained by substituting the preprocessed data. The results were made more intuitive by data visualization and 3D fitting diagram. The sample Pearson correlation coefficient method, Monte Carlo method and nonlinear programming model are used to obtain the optimal solution of when filtering effi-ciency. On the basis of meeting the actual production conditions, by using the data after dimension-ality elimination and transformed into maximized variables, and substituting them into the single objective programming model after dimensionality reduction by weighted combination, the com-bination of structural parameters can make the filtering efficiency as large as possible and the fil-tering resistance as small as possible.
