  1. 1. Isocyanates formation from thermal degradation of polyurethane foam during welding of district heating pipes

    Master-uppsats, KTH/Ergonomi

    Författare :Muhammad Akram; [2023]
    Nyckelord :Polyurethane; Isocyanates; District Heating Pipes; Oxy-fuel Welding; Manual Metal Arc Welding;

    Sammanfattning : Polyurethane insulation foam, which is used as insulation on district heating steel and copper pipes, is made from polymerisation of polyol and diisocyanates monomers. Installation of new district heating pipes or replacement of old pipes involves masses of welding activities. LÄS MER

  5. 4. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

    Master-uppsats, KTH/Farkostteknik och Solidmekanik

    Författare :Mårten Vuorinen; [2022]
    Nyckelord :;

    Sammanfattning : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

  7. 5. INDAL - Modul för minskat varmvattensvinn i dusch

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

    Författare :Lovisa Persson; Ida Grunwald; [2022]
    Nyckelord :;

    Sammanfattning : I Sverige använder varje person 75 till 100 liter varmvatten per dag, vilket motsvarar 3-5 kWh [1]. Inväntan av rätt temperatur i dusch leder till ett estimerat varmvattensvinn på 8 liter per dag för ett litet hushåll. På ett år är det 2920 liter eller 107 kWh, vilket motsvarar ca 20 badkar i varmvattensvinn per år. LÄS MER
