Determining the Mechanical Properties of Solid Plates Obtained from the Recycling of Cable Waste
AI summary Read the abstract
This study investigated mechanical recycling of PVC cable sheath waste into solid plates by grinding and press moulding, evaluating the mechanical properties of the resulting recycled material.
In this article, the possibility of obtaining a solid plate from waste cable sheaths, by mechanical recycling, i.e., grinding, plasticising and pressing, is discussed-waste cable sheaths being pure PVC with a slight admixture of silicone. Press moulding was carried out under the following conditions: temperature 135 °C, heating duration 1 h and applied pressure 10 MPa. The yield point of the obtained solid plate obtained was 15.0 + -0.6 MPa, flexural strength 0.94 MPa, yield point 0.47 MPa and Charpy's impact strength 5.1 kJ/m2. The resulting solid plate does not differ significantly from the input material, in terms of mechanical strength, so, from the point of view of strength, that is, from a technical point of view, such promising processing of waste cables can be carried out successfully in industrial practice.
