    Sammanfattning : Commercial refrigerant industry is one of the biggest contributing factors toglobal warming according to a study by Mota-Babiloni et al. (2015). Studies have shown that emissions of fluorinated greenhouse gases' effect on global warming can increase from 1.3% (2004) to 7. LÄS MER

  3. 2. Quantification of Swelling in Sealing Materials

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Johanna Möller; Paula Erlandsson; [2021]
    Nyckelord :elastomer; rubber; gaskets; NBR; EPDM; swelling; diffusion coefficient; polymer technology; Technology and Engineering;

    Sammanfattning : The objective of this study was to quantify swelling in gasket materials to better predict the gaskets life span in heat exchangers. Alfa Laval produces plate heat exchangers, which are a common unit within the process industry. There are different types of plate heat exchangers, and one type is sealed with gaskets. LÄS MER
