  1. 1. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Victor Eric Pierre Chartrain; [2023]
    Nyckelord :Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Sammanfattning : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. LÄS MER

    Sammanfattning : Huvudmålet i projektet var att analysera det vanligt förekommande additivet glycerolmonostearat, GMS, i plastprover. Projektet är en del av ett samarbete mellan KTH och det norska företaget Norner. LÄS MER

  4. 3. Study of high flash point ethyl alcohol-based secondary fluids applied in Ground Source Heat Pumps systems

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Luis Enrique Carrion Domenech; [2019]
    Nyckelord :indirect refrigeration system; secondary fluid; flammability; alcohols; geothermal heat pump systems; properties.;

    Sammanfattning : Ethyl alcohol (ethanol) as secondary fluids is very popular as heat transfer fluid for indirect refrigeration system with ground source heat pump systems (GSHP) in several countries such as Sweden, Norway, Switzerland, Finland and other European countries. There have been several researches about the future ofthe refrigeration sector, refrigerants and refrigeration systems. LÄS MER

  5. 4. Bronze-Steel Friction Characteristics under the Lubrication of Modified Water/Glycerol Mixtures

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Karim Hamouda; [2017]
    Nyckelord :Glycerol; glycerol additives; stick-slip; shudder; friction modifiers;

    Sammanfattning : Increasing environmental awareness has driven a lot of research to look into various environmentally friendly lubricants which can replace more conventional mineral oil based lubricants. This is true in particular for marine and hydropower applications where the risk of lubricant leakage can be damaging to the local environment. LÄS MER

  7. 5. Evaluation of thermal and mechanical properties of the composite material of LignoBoost- lignin and recycled polyurethan : A preliminary feasibility study for a novel composite material from waste materials
