Feasibility study of Improvement Experimental Measurement and Thermodynamic Modelling of Contaminants Effect on the Thermo-Mechanical Properties of Industrial Petroleum recycled plastics wastes

The recycled plastics (RHDPE and RLDPE) were exposed to environment conditions for many years. Also the chemical contaminants had effects on the thermo-mechanical and other properties of these wastes. Then a weathering effect data is examined for both Iraqi and Foreign wastes on the thermo-mechanical and chemical properties (Tensile strength, modulus, elongation, impact and permeability).The different mathematical software model were applied to analysis these weathering – properties data in order to estimate which one or several among these properties had more effective by these weathering conditions such as (concentration of contaminant, time, temperature, thickness of specimen, length of spectra, basic property). The results shows that a multi-polynomial model has a best fit for most or several of properties to active weathering variables, also gave a vary residual and deviation than experimental analyzed data for both sources of wastes Iraqi and Foreign RHDPE and RLDPE. Also the results for thermo-mechanical and chemical properties prove that both tensile strength and modulus of elasticity thermo-mechanical properties and permeability / length of spectra chemical property were given a high quality of correction and fitting factor from 93-99 %, with less deviation and residual function was produced. And the results of RHDPE gave a best fit than RLDPE for most of checked analysis properties (thermo-mechanical and chemical properties).
