  1. 6. Characterization of thin laminate interface by using Double Cantilever Beam and End Notched Flexure tests

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Moiz Majeed; Rahitya Venkata Teja Geesala; [2020]
    Nyckelord :Double Cantilever Beam DCB ; End-Notched Flexure ENF ; Fracture toughness; Low density Polyethylene LDPE ; Three-point bending test;

    Sammanfattning : This thesis is intended to identify the mode I and mode II fracture toughness to characterize the thin laminate interface by using the Double Cantilever Beam test (DCB) and End Notched Flexure test (ENF). This study’s thin laminate was Polyethylene Terephthalate and Low-Density Polyethylene (PET-LDPE), which is mostly used by packaging industries in the manufacturing of packages to store liquid food.

  3. 7. Experimental Testing and MaterialModeling of Anisotropy in InjectionMoulded Polymer Materials

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Sharlin Shahid; Widaad Gukhool; [2020]
    Nyckelord :Anisotropy; Barlat2004; DIC; Hill48; Polyethylene; Tensile test;

    Sammanfattning : Experimental characterization of the mechanical properties in a thin injection moulded Low-Density Polyethylene (LDPE) plate is per- formed in this work. Anisotropy in LDPE at different material orientations is measured from the Digital Image Correlation (DIC) observation of the specimens during uniaxial tensile test. LÄS MER

  4. 8. Utvärdering av karboniserad LDPE som egenskapsförbättrande tillsats i nya LDPE-filmer

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Engin Cömert; [2018]
    Nyckelord :karbonisering; återvinning; miljö; LDPE;

    Sammanfattning : Tidigare forskning har visat att med hjälp av en speciell mikrovågsugn så kan man omvandla lågdensitetspolyeten (LDPE) till kemikalier med högre värde [1]. Ett försök på att omvandla plastavfall (LDPE) till en produkt med högre värde kommer att göras i detta projekt. LÄS MER

  5. 9. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Tajkia Syeed Tofa; [2018]
    Nyckelord :Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

    Sammanfattning : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.

  7. 10. Bridging the circularity gap in the LDPE value chain: A Tetra Pak and PolyPlank case study in Sweden

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Margot Brahmi; [2018]
    Nyckelord :Plastic recycling; Circular economy; Material recovery; Low-Density Polyethylene; Polylaminated food and beverage packaging; Earth and Environmental Sciences;

    Sammanfattning : The consumption of single use and disposable packaging has led to significant amounts of waste. A large share of food and beverage packaging products are multi-layered aseptic cardboard packages laminated with aluminium and principally with the Low-Density Polyethylene (LDPE) plastic material.
