  1. 21. Effects of Temperature and Moisture Content on Young’s Modulus in Glass Fiber Reinforced Polyamide

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Joel Sandberg; Samuel Sjölin; [2022]
    Nyckelord :Polyamide; nylon 66; PA66GF25; glassfiber reinforced polyamide; Young’s modulus; Polyamid; nylon 66; PA66GF25; glasfiberförstärkt polyamid; Youngs modul.;

    Sammanfattning : This thesis was made in cooperation with Roxtec. Roxtec specialises in cable sealingsolutions and are world leading in their area. In many of Roxtec’s products steel isused in the frame holding the sealing rubber. To lower Roxtec’s environmental foot-print plastic would be used instead in the frames if possible, more specific polyamide6. LÄS MER

  3. 22. Analytical Methods for High Molecular Weight UV Stabilizers

    Master-uppsats, KTH/Kemi

    Författare :Elin Ljungström; [2022]
    Nyckelord :hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

    Sammanfattning : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). LÄS MER

  4. 23. Reaching Net-Zero in the Chemical Industry - A study of roadmaps for reducing greenhouse gas emissions

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ylva Kloo; [2022]
    Nyckelord :Chemical industry; roadmaps; scenarios; net-zero emissions; recycling; biobased feedstock; CCU; CCS; electrification; efficiency improvements; framework conditions; Technology and Engineering;

    Sammanfattning : Following the decision set by the EU of a net-zero greenhouse gas emission target for 2050, several industries have made roadmaps for how these reductions will be achieved. This thesis investigates the chemical industry roadmaps in order to assess how they envision their role in reaching the EU target. LÄS MER

  5. 24. Mikroplast i tumlare - Metodutveckling i sökandet efter mikroplaster i tarminnehåll från tumlare

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Thea Eriksson; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : An ever-growing problem is the increasing amount of microplastics in the sea and how they affect marine organisms. Microplastics are small pieces of plastic that are between 0.1 - 500 micrometres. They are divided into primary and secondary microplastics. LÄS MER

  7. 25. Exploring flexible structures in 3D-printed bio-based materials to closely mimic the properties of foam

    Master-uppsats, Lunds universitet/Innovation

    Författare :Fredrik Sinclair; [2021]
    Nyckelord :CAD; Design; Product Development; Foam; Additive Manufacturing; Structure; Technology and Engineering;

    Sammanfattning : Plastic is used for an enormous number of products worldwide, one of these being conventional foam. This foam can be found in everything from an office chair to a sponge. To be able to move away from non-renewable sources in hope of protecting our planet we need to find alternatives materials and manufacturing methods for these products. LÄS MER
