Control of Polyethylene’s Radiation Cross-Linking by Gamma Irradiation in Acetylene Atmosphere

Abstract

To produce cross-linked polyethylene using the radiation method, a lengthy procedure for irradiating the polyethylene is required. Reducing the time spent on irradiation will increase the yield of finished products per unit time and increase production efficiency. It has been experimentally confirmed that irradiation of polyethylene in the presence of hydrocarbon gases (for example, in the presence of acetylene) makes it possible to achieve the required degree of intermolecular cross-linking in less time. The article presents a modified algorithm for the production of cross-linked polyethylene, and identifies parameters whose changes can influence the speed of the production process. The problem of managing the production process is formulated in order to minimize the time spent on the production of cross-linked polyethylene. A description of mathematical models is given that make it possible to develop a control system for the production process of polyethylene modification using radiation exposure.
