摘要

利用连续超声波工艺对不同废橡胶浓度（5%、10%、20%、30% 和 40%）的废橡胶/PE（聚乙烯）混合物进行脱硫。超声波喇叭被设计成静态混合器，确保超声波在平行和交叉流动方向上的分布。这有助于混合物均匀脱硫。对超声波处理过的混合物和未处理过的混合物进行了对比分析测试。结果表明，在废橡胶浓度较低时（5%、10% 和 20%），超声波处理可有效帮助废橡胶在基质中分散。然而，当废橡胶的浓度达到 30% 和 40% 时，超声波处理过的样品就会出现不固化的迹象，这在它们的热性能、机械性能和流变性能上都很明显。

Designing a sonicating static mixer for the production of Thermoplastic Vulcanisate by devulcanization of waste rubber

The continuous ultrasonic process was utilized to devulcanize waste rubber/PE (Polyethylene) blends at varying waste rubber concentrations (5%, 10%, 20%, 30%, and 40%). The ultrasonic horn was designed as a static mixer, ensuring the distribution of ultrasonic waves in both parallel and cross‐flow directions. This helped devulcanize the blend uniformly. Both the ultrasonically treated blends and their untreated counterparts were tested for comparative analysis. Results demonstrated that at lower waste rubber concentrations of 5%, 10%, and 20% the ultrasonic treatment effectively helped in dispersing the waste rubber within the matrix. However, with higher concentrations of waste rubber 30% and 40%, the ultrasonically treated samples exhibited signs of uncuring, as evident in their thermal, mechanical, and rheological properties.

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
