Download or read book Highly Efficient Methods for Sulfur Vulcanization Techniques Results and Implications written by Dr Ali Ansarifar and published by Balboa Press. This book was released on 2022-02-09 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, two new methods are described and supported by extensive experimental results that measure the amounts of a sulfur-donor thiuram accelerator and a sulfenamide thiazole accelerator needed to provide monomolecular coverage of zinc oxide. These methods use zinc oxide with only one accelerator and no stearic acid to produce two single additives, that can efficiently cure rubber, despite using fewer chemicals. This is a departure from the past when efficiency in sulfur vulcanization was achieved by using a high volume of these chemicals. A few sulfur-donor accelerators that exist produce highly toxic nitrosamines during high-temperature mixing and curing. When safer accelerators are on hand to treat the zinc oxide, a suitable single additive will be available to replace the current sulfur cure systems in industrial rubber formulations. This will bring huge benefits to the manufacturers and users of these chemicals. It is preferable to use zinc oxide to determine the precise amount of the accelerator required for a satisfactory cure rather than relying on outdated methods that need to be modified. A software is also developed to help with the selection and management of zinc oxide and the accelerators for the sulfur vulcanization. Green rubber products are within reach.

Available in PDF, EPUB and Kindle. Book excerpt: The Science and Technology of Rubber, Third Edition provides a broad survey of elastomers with special emphasis on materials with a rubber-like elasticity. As in the 2nd edition, the emphasis remains on a unified treatment of the material; exploring topics from the chemical aspects such as elastomer synthesis and curing, through recent theoretical developments and characterization of equilibrium and dynamic properties, to the final applications of rubber, including tire engineering and manufacturing. Many advances have been made in polymer and elastomers research over the past ten years since the 2nd edition was published. Updated material stresses the continuous relationship between the ongoing research in synthesis, physics, structure and mechanics of rubber technology and industrial applications. Special attention is paid to recent advances in rubber-like elasticity theory and new processing techniques for elastomers. This new edition is comprised of 20% new material, including a new chapter on environmental issues and tire recycling.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years organic sulfur chemistry has been growing at an even faster pace than the very rapid development in other fields of chemistry. This phenomenal growth is undoubtedly a reflection of industrial and public demands: not only was sulfur recently in overall surplus for the first time in the history of the chemical industry but it has now become a prin cipal environmental hazard in the form of sulfur dioxide, sulfuric acid and hydrogen sulfide. Another reason, discernible in the last fifteen years, has been the desire, on the part of individual chemists and all types of research managers, to move away from the established chemistry of carbon into the less well understood and sometimes virgin chemistries of the other elements which form covalent bonds. As a result of this movement the last decade has seen the development of sulfur chemistry into a well-organized and now much better understood branch of organic chemistry. Enough of the detail has become clear to see mechanistic interrelationships between previously unconnected reactions and with this clarification the whole subject has in tum become systema tized and subdivided. The divalent sulfur chemistry of thiols, monosulfides, disulfides and polysulfides is a large area in itself, much of it devoted to oxidation-reduction and the breakage and formation of sulfur-sulfur bonds, although interesting discoveries are now being made about the reac tivity of certain sulfur-carbon bonds. Of course, this area has its own mas sive biochemical branch involving enzymes and proteins.
