This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As a result of the degradation experienced by polymers during their use and the impurities acquired during the recycling process, recycled polymers tend to have weaker mechanical properties than their virgin counterparts. Efforts have been made to upgrade recycled high-density polyethylene so that it may compete with virgin material, both economically and performance wise. This study focuses on the improvement of the mechanical properties of recycled high-density polyethylene (RHDPE) through the addition of multi-scale reinforcements. RHDPE composites reinforced with nanoclay, cellulose fibers, and a combination of the two were made. The effects of the reinforcements on the mechanical properties of the composites as well as the effect of compatibilization on the composite properties are highlighted. To address the economic objective of this study, bentonite is investigated as a possible alternative to montmorillonite as the nanofiller in the hybrid system. Bentonite is the ore from which montmorillonite is refined. So, it is less expensive than montmorillonite, but possesses the same layered silicate structure. In this study, a hybrid composite was made and shown to have increased tensile strength and elastic modulus compared to that of virgin HDPE. The nanoscale clay reinforcement was found to provide effective stiffening to the composite, while the microscale cellulose reinforcement was found to have effective strengthening."--Page iii.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers constitute a separate area on the environmental issues. Due to the generation of excessive amounts of polymers wastes by industries and householders, the world has confronted a serious crisis. Furthermore, due to the rising environmental awareness, economical and petroleum concerns an increasing attempt is being made to cope with the polymers wastes during the last few years. The traditional methods used to dispose polymer wastes such as combustion of polymers wastes or burying underground show a negative influence on the environment.From the existing studies, it seems that the recycling process is one of the best techniques to treat the waste polymer products. Recycling of polymers through advanced techniques is an important topic that is driven by both the commercial and environmental influences. Several new techniques have been developed along with the means of reusing recycled polymers. Some of the commercially important technological processes for recycling of waste polymers include mechanical recycling, chemical or feedstock recycling and energy recovery. Keeping in mind the advantages of the recycled polymers, this book gives an overview of on properties and processing of different kinds of recycled polymers along with their composites for a range of applications. This book is unique in the sense that it deals exclusively with the properties and processing of different recycled polymers which are otherwise considered as waste.The book is the outcome of untiring efforts of the researchers from different parts of the world with extensive research experience in the field of recycled polymers across different disciplines.

Download or read book Polypropylene written by J. Karger-Kocsis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: My heart sank when I was approached by Dr Hastings and by Professor Briggs (Senior Editor of Materials Science and Technology and Series Editor of Polymer Science and Technology Series at Chapman & Hall, respectively) to edit a book with the provisional title Handbook of Poly propylene. My reluctance was due to the fact that my former book [1] along with that of Moore [2], issued in the meantime, seemed to cover the information demand on polypropylene and related systems. Encour aged, however, by some colleagues (the new generation of scientists and engineers needs a good reference book with easy information retrieval, and the development with metallocene catalysts deserves a new update!), I started on this venture. Having some experience with polypropylene systems and being aware of the current literature, it was easy to settle the titles for the book chapters and also to select and approach the most suitable potential contributors. Fortunately, many of my first-choice authors accepted the invitation to contribute. Like all editors of multi-author volumes, I recognize that obtaining contributors follows an S-type curve of asymptotic saturation when the number of willing contributors is plotted as a function of time. The saturation point is, however, never reached and as a consequence, Dear Reader, you will also find some topics of some relevance which are not explicitly treated in this book (but, believe me, I have considered them).
Download or read book Development of Recycled Polypropylene Plastic Fibres to Reinforce Concrete written by Shi Yin and published by Springer. This book was released on 2017-02-02 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines a methodology for producing macro recycled polypropylene (PP) fibres with optimal mechanical properties and illustrates the reinforcing effects of recycled PP fibres in concrete. It describes the great potential of using these fibres in concrete applications such as footpaths and precast elements. Further, it sheds new light on the environmental impacts of using recycled PP fibres, which are evaluated by means of cradle to gate life cycle assessment based on the Australian context. The use of recycled PP fibre not only helps reduce consumption of virgin materials like steel or plastic but also provides an attractive avenue for recycling plastic waste. The book will appeal to engineers, governments, and solid waste planners, and offers a valuable reference for the plastic waste recycling and plastic fibre reinforced concrete industries. /div

Book excerpt: This book discusses the recent advances in the wastes recycling technologies to provide low-cost and alternative ways for nanomaterials production. It shows how carbon nanomaterials can be synthesized from different waste sources such as banana fibers, argan (Argania spinosa) seed shells, corn grains, camellia oleifera shell, sugar cane bagasse, oil palm (empty fruit bunches and leaves) and palm kernel shells. Several nanostructured metal oxides (MnO2, Co3O4,....) can be synthesized via recycling of spent batteries. The recovered nanomaterials can be applied in many applications including: Energy (supercapacitors, solar cells, etc.) water treatments (heavy metal ions and dyes removal) and other applications. Spent battery and agriculture waste are rich precursors for metals and carbon, respectively. The book also explores the various recycling techniques, agriculture waste recycling, batteries recycling, and different applications of the recycled materials.

Book excerpt: Micro and Nano Fibrillar Composites (MFCs and NFCs) from Polymer Blends is a comprehensive reference for researchers, students and scientists working in the field of plastics recycling and composites. The book aims to determine the influence of micro and nanofibrillar morphology on the properties of immiscible blend systems. Chapters cover micro and nanofibrillar composites based on polyolefin, liquid crystal polymer, biodegradable polymers, polyester and polyamide blends in various industrial application fields. The book brings together panels of highly-accomplished experts in the field of plastics recycling, blends and composites systems. For several decades, plastic technology has played an important role in many industrial applications, such as packaging, automobiles, aerospace and construction. However the increasing use of plastics creates a lot of waste. This has led to restrictions on the use of some plastics for certain applications and a drive towards recycling of plastics. More recently, microfibrillar in-situ composites have been prepared from waste plastics such as PET/PP, PET/PE and Nylon/PP as a way of formulating new high performance polymer systems. This book tackles these issues and more, and is an ideal resource for anyone interested in polymer blends. Provides information on MFC and NFC based polymer blends that have been accumulated over the last 25 years, providing a useful reference Adopts a novel approach in terms of understanding the relationship between processing, morphology, structure, properties and applications in micro and nanofibrillar composites Contains contributions from leading experts in the field from both industrial and academic research
Download or read book Carbon Fibres and Their Composites written by Erich Fitzer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proper choice of technology is a complex decision, particularly for developing countries, as it depends not only on local needs and conditions but also, importantly, on the national political context and, increasingly, on the international environment. This technological choice carries with it the genetic code of the nation's future development. Many developing countries which lack the needed infrastructure do not have real options; others with a reservoir of scientific and engineering skills and explicit SIT strategies, can indeed choose between alternatives. Turning to the technologies themselves, these cover a wide spectrum: traditional technologies that are low-cost, low-energy and often better suited to meet basic needs; more sophisticated technologies which are highly knowledge-intensive and require large capital outlays for research, product design and manufacturing; and still others which depend upon a blending of modern technology with traditional methods to create products and processes more suited to local needs. Even within the group of advanced technologies, there is considerable differentiation, and those at the lower end of the product cycle are clearly within reach by the newly industri alizing countries.
