 Kohlgrüber, K.
Publication: 2007
ISBN: 9781569904220
Hardcover: 354 pages
Price: $199.95

Co-rotating screws are used in many branches of industry for producing, preparing and/or processing highly viscous materials. They find a wide variety of applications especially in the plastics, rubber and food industries. Co-rotating twin-screw machines usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Well-founded knowledge of machines, processes and material behavior are required in order to design twin-screw extruder for economically successful operations. This book provides basic engineering knowledge regarding twin-screw machines; it lists the most important machine-technical requirements and provides examples based on actual practice. Better understanding of the processes is emphasized as this is a prerequisite for optimizing twin-screw designs and operating them efficiently. Besides basic functions, such as compounding, the book focuses on the historical development of twin-screws, the geometry of the screw elements (fundamentals, basic patents, patents overview), material properties and material behavior in the machine, fundamentals of feed behavior, pressure build-up and power input, examples of applications for various processing tasks, compounding: tasks, applications, processing zones, potential and limits of modeling, scaling-up various processes, and machine design including drives and materials.

Subtitle: Machine - Process - Product
 Harris, H.
Publication: 2004
ISBN: 9781569903636
Hardcover: 153 pages
Price: $99.95


In a very practical and down-to-earth way the author explains how quality in extrusion can be measured, controlled, and improved. In particular, he conveys an understanding of how extruders should be controlled and what good, closed-loop controls can accomplish. The author's approach and style clearly conveys that he has been involved in this field for many years and that he knows from experience what kind of problems an extrusion operator faces and how to successfully tackle these problems. This book is a helpful tool to improve and stabilize the extrusion process, thus facilitating a more profitable operation.

分析和故障排除单螺杆挤出

Picture of Analyzing and Troubleshooting Single-Screw Extrusion

分析和故障排除单螺杆挤出
 Campbell, G., Spalding, M.
出版: 2013
ISBN: 9781569904480
精装: 777 页/458 数据/87 图表
价格: $249.95
The book teaches the fundamentals of single-screw extrusion such that fast troubleshooting and process optimization and design are possible. The fundamental processes that are occurring in the machine are developed from the natural reference point of a rotating screw rather the traditional rotating barrel. These fundamentals are then combined with the chemistry of polymers and the physical properties related to processing to troubleshoot and optimize extrusion processes. Many industrial extrusion problem case studies are presented. In each case study, the root cause of the problem is identified along with the solution. A fundamental view of the processes that occur in a single-screw machine from the natural reference frame; i.e., screw rotation. The theory is discussed and compared to experimental data and to a rotating barrel reference frame. Topics include: polymerization chemistry and degradation mechanisms for polymers, physical properties related to processing (e.g., rheology, heat capacity, dynamic friction, bulk density and pellet compaction, melt density), and 30+ case studies for troubleshooting extrusion problems. A detailed description of the problem and the solution is presented so the reader can implement the solution on their own equipment.

 Rao, N.
出版:2014
ISBN:9781569905685
装帧:128 pages
价格:$12.95

The widespread use of large scale units for manufacturing blown film, blow-molded articles, flat film, and extruded pipes necessitates troubleshooting on site. This book provides practical computational tools which can be applied easily on the shop floor to obtain quick solutions in these and many other areas of polymer extrusion.
