Control of Physical Processes in an Extrusion Line Polymer Sleeves Production
Source abstract
Abstract
This article describes the operation principle of an extrusion line for producing a polypropylene film for sleeves. The advantages and disadvantages of the technological and structural nature for an extrusion line are presented, as well as the stages of polymer sleeves with the calculation of technological parameters and a description of the main purpose of each stage. The film quality is described, such as the turbidity, coefficient of friction, glossiness, and breaking strength. The dependence of the milkiness on the average cooling temperature of the extruder head is defined. The glossiness dependence is calculated on the cooling temperature of the extruder head. The dependence of the friction coefficient on the cooling temperature of the extruder head was established. The influence of the crystallization line height on the glossiness of the film is defined. The influence of the crystallization line height on the milkiness is shown. The dependence of fluctuations in the average thickness (thickness difference) of the film on the thickness of the forming slot is found. The dependence of fluctuations in the average thickness (thickness difference) of the film and degree of inflation of the sleeve is discovered. The relationship between the quality parameter of the film and technological parameters of its production process has been determined. An automated system for temperature control has been developed in the production of polyethylene film by installing a temperature sensor with feedback.
