内容説明
Foam Extrusion: Principles and Practice combines the science of foam with the engineering of extrusion processes in one comprehensive volume, joining scientific principles and engineering practice. Starting with the fundamentals and then moving to phase separation, the text lays the scientific foundation in such a manner that the microscopic transition from a nucleus to a void (nucleation) and macroscopic movement from a void to an object (formation) are plausibly addressed. The last section of the book presents interesting foam extrusion developments, demonstrating how scientific findings can be applied to the engineering field, from principles to batch experimentation and continuous foaming. Each chapter concludes with a section of references for further study, and most include a nomenclature section and/or summary section as well. Drawing from the experience of the editor and the authors, Foam Extrusion: Principles and Practice captures the interesting evolution of foam extrusion, and offers a solid foundation for future developments. It is an informative guide for anyone involved with this field.
