DMI-9812969Manas-Zloczower Mixing is an important component of practically every polymer processing operation. Material processability and product properties are highly influenced by mixing quality. Applying the findings of fundamental research on mixing mechanisms to processes taking place inside complex industrial mixing devices, such as internal mixers or twin screw extruders, poses a big challenge. Developing scale-up rules for translating the results of experiments on small laboratory mixers to industrial equipment is another typical problem encountered in practice. This research project is aimed at identifying the important design and processing parameters enhancing realization of the mixing process in various processing equipment. Research will be conducted to define mixing criteria for process control and optimization and for equipment scale-up. The work will be conducted in close cooperation with researchers at DuPont Experimental Station in Wilmington, Delaware. Flow simulations of various mixing equipment and development of mixing criteria will be conducted at Case Western Reserve University. Flow visualization and compounding experiments will be performed at DuPont Experimental Station. This interactive program could provide valuable findings to gain further insight and understanding into the mixing mechanisms and material behavior during processing. In turn, an in-depth knowledge of the equipment used and the behavior of the materials being processed will render the key for process optimization and the development of scale-up rules. The results of this research will far and foremost help enhancing the efficiency of existing manufacturing processes in the polymer processing industry. However, the information base generated through this work will impact also on equipment manufacturing. Comprehension of the links between equipment design and process efficiency can lead to future generations of machines for processing of advanced materials.

Manas-Zloczower混合是几乎所有聚合物加工操作的重要组成部分。 混合质量对材料加工性和产品性能有很大影响。 将混合机理的基础研究成果应用于复杂的工业混合设备（如密炼机或双螺杆挤出机）内的过程，是一个巨大的挑战。 在实践中遇到的另一个典型问题是制定放大规则，将小型实验室混合器的实验结果转化为工业设备。 该研究项目旨在确定重要的设计和工艺参数，以提高各种加工设备中混合过程的实现。 将进行研究，以确定工艺控制和优化以及设备放大的混合标准。 这项工作将与特拉华州威尔明顿杜邦实验站的研究人员密切合作进行。 各种混合设备的流动模拟和混合标准的制定将在凯斯西储大学进行。 流动可视化和混合实验将在DuPont实验站进行。 这个互动程序可以提供有价值的发现，以获得进一步的洞察力和理解的混合机制和材料在加工过程中的行为。 反过来，对所用设备和加工材料行为的深入了解将成为工艺优化和扩大规模规则开发的关键。 这项研究的结果将大大有助于提高聚合物加工行业现有制造工艺的效率。 然而，通过这项工作产生的信息库也将影响设备制造。 理解设备设计和工艺效率之间的联系可以引导未来几代加工先进材料的机器。
