Download or read book Polymer Extrusion written by Pierre G. Lafleur and published by John Wiley & Sons. This book was released on 2014-05-09 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extrusion is by far the most important and the oldest processing and shaping method for thermoplastic polymers. This process concerns almost all synthetic polymers, as well as elastomers or food materials. Single-screw extrusion is mainly used nowadays to manufacture finished goods or semi-finished products. More than 90 million tons of thermoplastics are therefore processed every year. Twin-screw extrusion may be divided into two systems: contra-rotating systems used within the context of PVC extrusion, for the manufacture of pipes or profiles; and co-rotating systems experiencing nowadays a very significant development, because of their significant adaptability and flexibility, which enables the manufacture of specific materials (polymer alloys, thermoplastic elastomers, filled polymers, nanocomposites). Extrusion is carried out by passing molten polymer through a tool called die that will give the product its final shape (films and sheets, rolled products, and electric cables). Thanks to the design of dies, we obtain at the output a product with controlled dimensions, uniform speeds and homogeneous temperatures. The book will discuss the same production types, but only in the case of coextrusion flows, i.e. multilayer stratified products. First of all, we will present in this book the physics of the mechanisms at stake, then propose more or less complex models in order to describe these mechanisms and then go forward in the interpretation of results and the control of condition flows.

Download or read book Modeling and Simulation in Polymers written by Purushottam D. Gujrati and published by John Wiley & Sons. This book was released on 2010-03-30 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling a gap in the literature and all set to become the standard in this field, this monograph begins with a look at computational viscoelastic fluid mechanics and studies of turbulent flows of dilute polymer solutions. It then goes on discuss simulations of nanocomposites, polymerization kinetics, computational approaches for polymers and modeling polyelectrolytes. Further sections deal with tire optimization, irreversible phenomena in polymers, the hydrodynamics of artificial and bacterial flagella as well as modeling and simulation in liquid crystals. The result is invaluable reading for polymer and theoretical chemists, chemists in industry, materials scientists and plastics technologists.

Download or read book Computer Modelling of Polymer Processing written by E. Andreassen and published by iSmithers Rapra Publishing. This book was released on 1992 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of computers to numerically analyse polymer processing was first reported as for back as the 1950's, and the first commercial software became available around 20 years ago. Much research has been carried out since that time, and this report aims to summarise contemporary trends in both commercial and academic research and development. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

Download or read book Design of Extrusion Forming Tools written by Olga Carneiro and published by Smithers Rapra. This book was released on 2012-12-19 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of extrusion forming tools (dies and calibrators) is a difficult task usually performed by the employment of experimental trial-and-error procedures, which can hinder the performance and cost of the tools, may increase the time to market of new extruded products and limit their complexity.This book provides detailed information on the design of extrusion forming tools. It describes the main problems to be faced when designing dies and calibrators, the most relevant polymer properties to be considered in the design process, the specific problems related to several types of conventional extrusion dies, and recent developments on the design of special dies and process modeling. It is an updated and unique book on the subject, where each chapter is prepared by internationally recognized experts. Having in mind its nature, it is expected to become a useful reference book for higher education students (both undergraduate and graduate ones), teachers, researchers and engineers active in the extrusion industry.
