Abstract:За допомогою розробленої математич-ної моделі виконано аналіз процесу охоло-дження екструдованої полімерної плівки на барабані із внутрішнім охолодженням. Досліджено залежність середньої темпе-ратури полімерної плівки за умови вихо-ду барабана на стаціонарний (усталений) тепловий режим. Показано, що зі збільшен-ням товщини плівки та (або) зменшенням швидкості необхідно враховувати прогрів барабана під час його попередніх обертів до виходу на стаціонарний режим Ключові слова: екструзія, плоска полі-мерна плівка… Show more
“…The main consumers of articles from biodegradable polymeric materials are the packaging industry and agriculture. In this case, the basic type of such products is the sleeve and flat polymeric films made by extrusion [20][21][22][23][24][25][26]. At the same time, the use of various mixing and dispersing elements in extruders significantly improves the distribution of components of the processed composition in the polymeric matrix [27].…”

“…Within the last decades computer models promoted significant improvement of the analysis of formation processes therefore now they are widely used for process optimization [3][4][5][6]. Computer models can minimize undesirable variations of thickness of a wall of a finished product and reduce the weight of a finished product at ensuring of its durability.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
