  1. 21. Control Aid Implementation -Modelling and simulation of triple extruder-

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Karl Langsér; [2023]
    Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE

  3. 22. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    University essay from Lunds universitet/Innovation

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

    Abstract : 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. READ MORE

  4. 23. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

    University essay from KTH/Byggnadsmaterial

    Author : Charlotte Jaeger; [2023]
    Keywords : ;

    Abstract : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. READ MORE

  6. 25. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
