Available in PDF, EPUB and Kindle. Book excerpt: Recycling of Polyurethane Foams introduces the main degradation/depolymerization processes and pathways of polyurethane foam materials, focusing on industrial case studies and academic reviews from recent research and development projects. The book can aid practitioners in understanding the basis of polymer degradation and its relationship with industrial processes, which can be of substantial value to industrial complexes the world over. The main pathways of polymer recycling via different routes and industrial schemes are detailed, covering all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials that are then compared with depolymerization approaches. The book examines life cycle assessment and cost analysis associated with polyurethane foams waste management, showing the potential of various techniques. This book will help academics and researchers identify and improve on current depolymerization processes, and it will help industry sustainability professionals choose the appropriate approach for their own waste management systems, thus minimizing the costs and environmental impact of their PU-based end products. Offers a comprehensive review of all polyurethane foam recycling processes, including both chemical and mechanical approaches Assesses the potential of each recycling process Helps industry-based practitioners decide which approach to take to minimize the cost and environmental impact of their end product Enables academics and researchers to identify and improve upon current processes of degradation and depolymerization

Book excerpt: Toxic fire effluents are responsible for the majority of fire deaths, and an increasing large majority of fire injuries, driven by the widespread and increasing use of synthetic polymers. Fire safety has focused on preventing ignition and reducing flame spread through reducing the rate of heat release, while neglecting the important issue of fire toxicity. This is the first reference work on fire toxicity and the only scientific publication on the subject in the last 15 years. Assessment of toxic effects of fires is increasingly being recognised as a key factor in the assessment of fire hazards. This book raises important issues including the types of toxic effluents that different fires produce, their physiological effects, methods for generation and assessment of fire toxicity, current and proposed regulations and approaches to modelling the toxic impact of fires. The contributors to Fire toxicity represent an international team of the leading experts in each aspect of this challenging and important field. This book provides an important reference work for professionals in the fire community, including fire fighters, fire investigators, regulators, fire safety engineers, and formulators of fire-safe materials. It will also prove invaluable to researchers in academia and industry. Investigates the controversial subject of toxic effluents as the cause of the majority of fire deaths and injuries Describes the different types of toxic effluents and the specific fires that they produce, their physiological effects and methods for generation Provides an overview of national and international fire safety regulations including current and proposed regulations such as a standardized framework for prediction of fire gas toxicity

Download or read book Preparation of Rigid Polyurethane Foams Catalyzed by Delayed Action Catalyst Derived from Copper-amine Complexes and Carboxylic Acid written by Koatchapan Nimaboot and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, a delayed action catalyst system is used in the preparation of rigid polyurethane foams. The delayed action catalysts were synthesized from reaction between copper-amine complexes and carboxylic acids in ethylene glycol as a solvent to give the salts of copper-amine complex and carboxylic acid. Copper-amine complexes used in this study were Cu(OAc)2(en)2 and Cu(OAc)2(trien) (where en = ethylenediamine and trien = triethylenetetramine). Carboxylic acids used were salicylic acid (Sal) and acetic acid (Ac). Copper-amine complex/carboxylic acid salts, namely Cu(OAc)2(en)2/Sal, Cu(OAc)2(en)2/Ac and Cu(OAc)2(trien)/Sal were studied. UV-Visible spectroscopy and IR spectroscopy were used to characterize the structure of copper-amine complex/salicylic acid salts. The reaction times in the foam formation, physical and mechanical properties of foams are studied. When only copper-amine complex was used as a catalyst, the foam formation was fast. However, there was a problem with the fast gel time which resulted in difficulty in the foam processing. This problem could be solved by using copper-amine complexes/carboxylic acid salts as catalysts, which gave longer gel time while the tack free time was not too long. Cu(OAc)2(en)2/Sal and Cu(OAc)2(trien)/Sal at the mole ratios of 1:1 and 1:0.5, respectively were suitable catalysts, which had gel time about 60 seconds while tack free time was not too slow when compared with commercial catalyst (DMCHA). The gel time of 60 sec was long enough for pouring the mixture of foam formulation into a mold.

Available in PDF, EPUB and Kindle. Book excerpt: Until now, the literature has offered a rather limited approach to the use of fundamental kinetics and their application to catalytic reactions. Subsequently, this book spans the full range from fundamentals of kinetics and heterogeneous catalysis via modern experimental and theoretical results of model studies to their equivalent large-scale industrial production processes. The result is key knowledge for students at technical universities and professionals already working in industry. '... such an enterprise will be of great value to the community, to professionals as well as graduate and undergraduate students attempting to move into the field of modern catalysis and kinetics. I strongly recommend you publish this book based on the proposal.' - Prof. Dr. G. A. Samorjai, University of California 'Both authors are well respected specialists, with a very long record of original top-quality work and an international reputation. A book from these authors will be considered an authoritative piece of work, I definitely support this project and I am looking forward to use the book when published.' - Prof. Dr. D. E. Resasco, University of Oklahoma 'I wholly support the proposed project. The authors are very competent young colleagues and there is a real need for such a textbook' - Prof. Dr. G.

Available in PDF, EPUB and Kindle. Book excerpt: Reactive inkjet printing uses an inkjet printer to dispense one or more reactants onto a substrate to generate a physical or chemical reaction to form a product in situ. Thus, unlike traditional inkjet printing, the printed film chemistry differs to that of the initial ink droplets. The appeal of reactive inkjet printing as a chemical synthesis tool is linked to its ability to produce droplets whose size is both controllable and predictable, which means that the individual droplets can be thought of as building blocks where droplets can be added to the substrate in a high precision format to give good control and predictability over the chemical reaction. The book starts by introducing the concept of using reactive inkjet printing as a building block for making materials. Aspects such as the behaviour of printed droplets on substrate and their mixing is discussed in the first chapters. The following chapters then discuss different applications of the technique in areas including additive manufacturing and silk production, production of materials used in solar cells, printed electronics, dentistry and tissue engineering. Edited by two leading experts, Reactive Inkjet Printing: A Chemical Synthesis Tool provides a comprehensive overview of this technique and its use in fabricating functional materials for health and energy applications. The book will appeal to advanced level students in materials science.
