The main objective of this proposal, which was already submitted last year without success, is to replace a very old internal batch mixer acquired in 1987. This set-up is actually one of the most used processing equipment in our lab (35 h/week). Over the years, it was maintained and upgraded several times to continue working under good conditions. Presently, it is no longer working correctly (leaks) and is regularly out of service (electronics) limiting the possibility to perform on-time the current projects on polymer blends, nanocomposites, foams, hybrids, etc., as well as to develop new ones. We believe that it has fully accomplished its duties and now is the time to replace it before complete shutdown occurs leaving no other alternatives. The requested equipment is a modular Plasti-Corder Torque Rheometer connected to a Prep Mixer, 304 Stainless Steel Three Section Mixer from C.W. Brabender instruments. The set-up includes three rotors/blades configurations (rollers, cams and Banbury) for a wide range of processing conditions needed for our research projects on thermoplastics and elastomers. It also has a larger mixing chamber (350-420 cm3) to prepare higher amount of materials and be closer to more industrial conditions compared to our old equipment (only one set of rotors and 40 cm3) Since both applicants (F. Mighri and D. Rodrigue) are unifying their efforts to build a common laboratory space (processing, rheology and characterization), the proposed equipment will help in building this research area and attracting the best students and postdoctoral fellows to work on more challenging projects, thus enhancing the quality of their training. The equipment will also be accessible to students from other departments and universities in need of this processing tool.

该提案的主要目的是取代1987年购买的一台非常旧的间歇式密炼机，该提案已于去年提交，但没有成功。该装置实际上是我们实验室中最常用的加工设备之一（每周35小时）。多年来，它被维护和升级了几次，以继续在良好的条件下工作。目前，它不再正常工作（泄漏），并定期停止服务（电子），限制了按时执行聚合物共混物，纳米复合材料，泡沫，混合物等当前项目的可能性，以及开发新的。我们认为，它已经完全完成了自己的职责，现在是在完全关闭之前取代它的时候了，没有其他选择。 所要求的设备是连接到制备混合器的模块化Plasti-Corder转矩流变仪，304不锈钢三段混合器，来自C.W. Brabender仪器。该装置包括三种转子/叶片配置（辊、凸轮和班伯里），适用于我们的热塑性塑料和弹性体研究项目所需的各种加工条件。它还具有更大的混合室（350-420立方厘米），与我们的旧设备（只有一套转子和40立方厘米）相比，可以制备更大量的材料，更接近工业条件。 由于两个申请人（F。Mighri和D. Rodrigue）正在统一他们的努力，以建立一个共同的实验室空间（加工，流变学和表征），拟议的设备将有助于建立这一研究领域，并吸引最好的学生和博士后研究员从事更具挑战性的项目，从而提高他们的培训质量。该设备也将提供给需要这一处理工具的其他部门和大学的学生。
