INVESTIGATION OF THE FEATURES OF THE ACCELERATED DEGRADATION OF POLYOLEFINE WASTES

Abstract

Investigation of the features and conditions of accelerated degradation of films based on PE wastes to create and develop an efficient technology for the utilization of flexible polyolefin packaging. The chemical composition of the inorganic residue after the burning of polymers wastes was determined by X-ray fluorescence method. The determination of the MFI of PE was carried out in accordance with ISO 1133: 1997 on a capillary viscometer of constant pressure at a temperature (190 ± 0.5) °С and a weight of 2,16 kg. Deformation-strength properties - according to ASTM D638. Ash content - according to ISO 3451-2: 1998 «Plastics. Determination of ash content». The ability to accelerate the degradation of polyolefine wastes in an environment was established. The changes of mechanical properties of PE films of different composition in conditions of artificial aging were investigated. The ability of calcium carbonate to exhibit the effect of oxide additives in PE films during the aging process was revealed. The features of accelerated degradation of polyolefine wastes in artificial aging conditions were first discovered and investigated. Obtained initial data for the production of PE film technology based on polyolefine wastes, then capable of accelerated degradation under environmental conditions
