  1. 11. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    Master-uppsats, Lunds universitet/Innovation

    Författare :Tora Abrahamsson; Juliana Kalling; [2023]
    Nyckelord :Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Sammanfattning : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. LÄS MER

  3. 12. Optimerad sandwichvägg i prefabricerad betong

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Majed Alsmail; Baqer Rubaij; [2023]
    Nyckelord :sandwich elements; thin concrete slabs; outer concrete layer; anchoring; anchoring systems; granular rupture in outer layer; anchor pull-out; adhesion; outer layer failure; loads; reinforcement; recesses; sandwichelement; tunna betongskivor; yttre betongskiva; förankring; förankringssystem; konbrott i yttre skivan; bygel utdrag; vidhäftning; brott i ytterskiva; belastningar; armering; ursparningar;

    Sammanfattning : As part of the work in this project, a literature review is conducted to determine the optimal thickness of the outer concrete layer in prefabricated concrete sandwich elements. These elements are used as exterior walls in buildings and consist of a load-bearing inner concrete layer, an intermediate insulation layer, and an outer concrete layer that forms the building's facade.

  4. 13. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Albin Zetterqvist; Linus Hjelm; [2023]
    Nyckelord :Digital image correlation; Finite element; Predictive capability; Model calibration; FEM; DIC; Modellkalibrering;

    Sammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER

  7. 15. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Elise Meurs; [2023]
    Nyckelord :Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Sammanfattning : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.
