聚合物加工领域中,人们都熟知“混合”和“混炼”这两个术语。聚合物的挤出中涉及“混合”的理论和实践,聚合物的“混炼”中也涉及挤出的理论和实践,因而,充分理解“混合”与“混炼”的基本概念是至关重要的。国外有关挤出的专著中,也多专节讨论挤出中的“混合”以及挤出机在“混炼”中的应用。但是,有些资料上却将“混合”一词来代替工程界常用的“混炼”一词。这可能是mixing一词的多种译法造成的名词“混乱”。 In the field of polymer processing, the terms “mixing” and “kneading” are well known. The theory and practice of “mixing” are involved in the extrusion of polymers. The theory and practice of extrusion are also involved in polymer “mixing.” Therefore, it is important to fully understand that the basic concept of “mixing” and “mixing” important. Exotic foreign monographs, but also more sections to discuss the extrusion of the “mixed” and the extruder in the “mixing” application. However, in some sources, the word “mixed” is used instead of the word “mixed” commonly used in engineering. This may be the noun “chaos” caused by various translations of the word mixing.
