مقارنة بعض الخواص الميكانيكية لخلائط البولي إيثيلين

الملخص EN

This study was carried out to clarify the difference between polyethylene mixtures in terms of elasticity (flux and fusion) and tensile force (expansion and elongation) according to ISO and ASTM specifications for raw material and the extent to which recycled material can be used in the field of manufacturing and compare its quality with raw material.

Seven samples of different ratios were selected and tested at the Misurata Factory Laboratory.

The results showed the lowest value for the flow and fusion test in the seventh sample (100% SABIC net crude) and 0.3 g / 10 minutes, while the highest value in the third sample (50% Density and 50% low density lumen) 1.01 g / 10 min.

The minimum value of elongation for the sixth sample was 100% (high net density) 14.21% and the lowest tensile strength 0.16N / mm2 for the same sample, while the highest elongation value was for the seventh sample 400.55% and the highest tensile strength of 0.50 N / mm2.
