  1. 1. Assessment of a Sustainable Water-based Lubricant for Electric Drivelines : Lubrication and Cooling performance of a Water-based Lubricant

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

    Författare :Ugo Jantel; [2022]
    Nyckelord :Water-based Lubricant; Cooling; Driveline;

    Sammanfattning : In recent years, the impact of humans on the environment has been the subject of much debate. Car companies in particular are among the main actors in this environmental degradation with the polluting aspect of combustion cars. LÄS MER

  3. 2. Tribology of newly developed EAL versus water in hydropower turbine bearings

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

    Författare :Nayan Dhakal; [2019]
    Nyckelord :water-based lubrication; hydropower; turbine bearings; environmentally adaptive lubricants; modified water; viscosity modifiers; polyvinylpyrrolidone; poly sodium 4-styrenesulfonate ; UHMWPE; wear;

    Sammanfattning : The increasing demand for more readily bio-degradable, renewable and non-toxic environmentally adaptive lubricants with a lower degree of bioaccumulation has escalated the investigation of water-based lubricants as the potential alternatives for conventional mineral-based oils. Water is an excellent environmentally adapted lubricant; however, it is a low viscous fluid and holds downsides of having corrosive nature and extremely low pressure-viscosity coefficient leading to insufficient load-carrying capacity.

  4. 3. Lubrication of the cutting tools in a stainless finishing line

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Johan Ek; [2016]
    Nyckelord :;

    Sammanfattning : In this thesis work the possible benefits of implementing a lubricant in the process of cutting stainless steel has been investigated. It has also be investigated how the lubricant could lower the wear rate in the cutting process. LÄS MER

  5. 4. Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Mikael Persson; [2009]
    Nyckelord :ELSD; HPLC; mixed-mode kolonn; polyglykol; dikarboxylsyra;

    Sammanfattning : Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. LÄS MER
