MODELING OF THE MICROINCLUSIONS INJECTION IN POLYMER MELT PROCESS

Abstract

Purpose of the study is obtaining dependencies of the parameters of the process of introducing a polymer mixture with micro sensors to a certain depth and given coordinates of the finished product.Object of the study is the process of formation of polymer products with the introduction of intelligent sensors. Research subject is technological parameters of processes of extrusion-injection molding of polymer products from the positioning of intelligent sensors. The relevance of the study - analysis of the properties of intelligent polymer materials and the expediency of using intelligent sensors in the industry in the manufacture of polymer products showed a small degree of study of this issue. Here we note that the possibility of embedding in the structure of polymeric materials of elements capable of responding to changes in force, temperature and other environmental parameters allows modeling a wide range of innovative "intelligent" materials. "Intelligent" materials are able to adequately respond to new loads, change their characteristics and form, as well as independently regulate the degree of their response to new conditions in accordance with the level of their change. Intelligent sensors allow you to monitor the processes that occur during the formation of products from "intelligent" PCMs, as well as "monitor" their condition during operation and adequately respond to changes occurring in them, due to environmental factors. The results of the study - the data available in the literature on the motion of solid particles in the fluid in the channels of process equipment cannot be used without additional analysis and calculations in different conditions of technological processes. To fulfill the task, the experimental-theoretical approach and the method of investigation were used. The obtained parametric dependences of the process of forming extrusion products from the positioned injection of microporations of a mixture of polymer with solid microparticles for materials: low pressure polyethylene of grade 15313-003, high-pressure polyethylene of mark 15803-020 and polypropylene of grade 2248-002. Certain reliability of obtaining experimental data. The relative error does not exceed 10 %. The geometric parameters of the channels and the angle of inclination of the injection mechanism are established, at which the introduction of a polymer melt with microparticles at the specified depth of immersion in the article is achieved as precisely as possible. This work may be useful in the study, design and production of equipment for the processing of polymeric materials and the receipt of products made of polymeric and composite materials.
