دانلود کتاب Biobased Lubricants and Greases: Technology and Products (Tribology in Practice Series)

توضیحاتی در مورد کتاب به زبان اصلی :

Due to the rise in petroleum prices as well as increasing environmental concerns, there is a need to develop biochemicals and bioproducts that offer realistic alternatives to their traditional counterparts; this book will address the lack of a centralized resource of information on lubricants and greases from renewable sources, and will be useful to a wide audience in industry and academia. It is based on 20 years of research and development at the UNI-NABL Center, and discusses the various types of vegetable oils available, comparing their characteristics, properties and benefits against those of typical petroleum oils as well as discussing common evaluation tests and giving examples and case studies of successful applications of biobased lubricants and greases. Whilst scientific and engineering research data is included, the book is written in an accessible manner and is illustrated throughout. Focuses on an industrial application of lubrication technology undergoing current explosive growth in the global market.Includes a detailed review of the material benefits of plant-based lubricants that include a better viscosity index and lubricity even at extreme temperatures, lower flammability due to higher flash points and lower pour points.Covers the basic chemistry of vegetable oils as well as their profiles for use in lubricants and greases and environmental benefits.Includes examples and case studies of where vegetable-based lubricants have been successfully employed in industry applications.
