SYNTHESIS AND STUDY OF THE PROPERTIES OF GEOMEMBRANES BASED ON RECYCLED POLYETHYLENE FILLED WITH SHEROBOD ARGILLITE MINERAL
Main Article Content
Abstract
This article investigates the recycling of end-of-life low-density polyethylene film waste, widely used in agriculture, and explores methods for modifying its properties with local minerals. The main objective of the research is to synthesize high-strength nanocomposite geomembranes by incorporating argillite from the Sherabad deposit as a nanofiller into recycled low-density polyethylene. The study analyzes the mechanisms by which nanodispersed argillite particles restore the physicochemical properties of the secondary polymer, which has been degraded by solar radiation and moisture. Experimental results show that when the mass fraction of argillite is between 5% and 10%, the material's tensile strength and heat resistance improve significantly. The resulting nanocomposite geomembranes can serve as an import-substituting, ecologically safe, and cost-effective insulation material for hydraulic structures and reservoirs in saline soil conditions.
