  1. 1. Friction and Wear Performance of Experimentally Developed Self-lubricating PPS/PTFE Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kimberly Rose Lagrama; [2019]
    Keywords : PPS; PTFE; self-lubricating composites;

    Abstract : Demanding applications, as well as the push to eliminate the need for fossil-fuel based lubricants, create the need for the development of high-performance polymers. Polyphenylene Sulfide (PPS) is an example of a high-performance polymer and has a high service temperature, good dimensional stability, and excellent chemical resistance. READ MORE

  3. 2. Tribological Performance of Hygrothermally Aged UHMWPE Hybrid Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Luca Palmeira Belotti; [2018]
    Keywords : UHMWPE; aging; polymers; tribology;

    Abstract : Stricter environmental regulations and trend of decreasing cost and increasing operational efficiency are the driving forces for the improvement of the tribological performance in many different industries. For example, in the case of hydropower plants, there has been increasing research carried out to achieve oil-free stations, which would substitute the oil-based lubricants with environmentally accepted lubricants or water.

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

  5. 4. Milking routines and hygiene in small-scale dairy farms in Mapepe, Choma and Batoka districts in Zambia

    University essay from SLU/Dept. of Clinical Sciences

    Author : Linda Olofsson; [2013]
    Keywords : milking hygiene; milking routines; small scale dairy farms; Zambia;

    Abstract : Småskalig mjölkproduktion är ett system som främjar regelbundna inkomster och spelar en viktig roll för att minska fattigdomen, ger anställningsmöjligheter och skapar välfärd samt säkrar en näringsrik livsmedelsförsörjning. Det finns cirka 2500 småskaliga mjölkbönder i Zambia men deras kunskap om bra mjölkningsrutiner och hygien är ofta dåliga. READ MORE

  6. 5. ECC-D4 Electostatic Oil Cleaner Design for Heavy-Duty Gas Turbine Applications

    University essay from Mekanisk värmeteori och strömningslära

    Author : Murat Gorur; [2010]
    Keywords : Energy System; Electrostatic Cleaner; Gas Turbines; Electrostatic Field; Turbine Oil; Oil Clenaer;

    Abstract : The turbine technology improvements from 1980 onwards have considerably increased mechanical and thermal stresses on turbine oils which, cause oil oxidation and thereby turbine oil degradation (Livingstone et al., 2007; Sasaki & Uchiyama, 2002). READ MORE
