AprašymasThis textbook covers the basic principles and the major phenomena encountered in polymer flow and processing. The problems found in the plastics processing industry are mostly related to the design and control of machines and equipment for producing satisfactory plastics products at a competitive price. In order to achieve this, one attempts to optimize the design parameters of machines and the operating conditions: temperature, speed, cooling, etc. It is also necessary to understand and control the relations between the formulation, the rheological behavior and the transformation properties. Mechanics, thermodynamics and rheology all play a significant role in polymer processing and this text introduces the reader to the basic equations and models directly applicable to industrial processes."
