Roofing sheets from recycled materials

Abstract

The purpose of this project is to study the mechanical and physical properties of recycled roofing materials. The pulp extracted from the UHT beverage boxes to get aluminum foil mixed with low density polyethylene. This can be used engineering and is an option to reduce the amount of UHT boxes left over to roofing sheets. In experiment 3 aluminum foil, medium size and fine, then hot and extruded with 6,8 and 10 bar compression, then cut into test pieces. To test mechanical and physical properties in accordance with the test standards: Torsion Testing Tensile strength Impact resistance Heat resistance, water absorption, and density testing. Compare the mechanical and physical properties of the material; different sizes of aluminum foil and compressive strength. To bring the best materials to the product. From the tests, it was found that the properties of recycled composite materials From the box UHT beetroot This is made of coarse aluminum foil. 18.23 MPa bending strength, 10.66 MPa tensile strength, 110.987 J / m2 impact resistance, 52.40 Shore-D Hardness, 0.62 % Water Absorption, 0.70 % Thickness Swelling, 1.086 g/m3 Density, 0.031 m2.K/W Thermal Resistance and 0.291 W/mK Thermal Conductivity is the best mechanical properties. Due to the large aluminum foil, it can be used for high strength. Which is higher than the aluminum foil of a smaller size.
