Development of a model to predict conditions for optimal orientation of nanoparticles in an extrusion process, together with methods of manufacturing non-leaching pipes based on nanoclay technology. The role of the nanoparticles is to form a barrier to render the pipe non-permeable to hydrocarbons and contaminants. The orientation of nanofillers determines the effectiveness of the pipe in preventing permeation.The innovation is the process of producing layers of aligned nanoclay platelets in the pipe body reducing permeation and leaching and using a multiscale model of the nanoclay/polymer systems to predict exfoliation and orientation of the platelets. The model is used to predict conditions for optimal alignment to form a barrier layer in extruded pipes. Factors involved include polymer blend selection, nanoclay type, surface treatment, compounding and processing methods & conditions.Project deliverables were the creation of a model based on the process parameters to predict the alignment and distribution of platelets in polymers, the development of compounding processes and extrusion technology to produce dispersed, exfoliated and aligned nanocomposite layers within the polymer matrix, the development of an online monitoring system to check the distribution and morphology of the nanoclays in the matrix and the adaptation of co-extrusion dies to accommodate the new approach.

开发一个模型，预测挤压过程中纳米颗粒的最佳取向条件，以及基于纳米粘土技术制造非沥滤管的方法。纳米颗粒的作用是形成屏障，使管道不渗透碳氢化合物和污染物。纳米填料的取向决定了管道在防止渗透方面的有效性。创新是在管道主体中产生排列的纳米粘土片晶层的过程，减少渗透和浸出，并使用纳米粘土/聚合物系统的多尺度模型来预测片晶的剥离和取向。该模型用于预测最佳对齐的条件，以在挤出管中形成阻挡层。所涉及的因素包括聚合物共混物的选择、纳米粘土类型、表面处理、配混和加工方法及条件。项目交付成果包括基于工艺参数的模型的创建，以预测聚合物中血小板的排列和分布，配混工艺和挤出技术的开发，以在聚合物基体中生产分散、剥离和排列的纳米复合材料层，在线监测系统的开发，以检查纳米粘土在基体中的分布和形态，以及共挤出模具的适应性，以适应新的方法。
