3. 2. Cleaning methods for removal of bound soiling on leather

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Olivia Cati Starck; [2023-11-14]
   Nyckelord :Conservation; Leather; Cleaning; Vulpex; White spirit; Isopropanol; Gellan gum gel;

   Sammanfattning : This thesis investigates the removal of bound soiling on leather using three cleaning methods: Vulpex (10%) in white spirit, gellan gum gel loaded in isopropanol and white spirit by itself. More detailed studies of cleaning methods for bound soiling in leather conservation are sparse. LÄS MER

4. 3. Nya metoder för fernissaborttagning – En komparativ studie

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Alica Larsson; [2023-11-08]
   Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

   Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

   Nyckelord :plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

   Sammanfattning : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. LÄS MER

7. 5. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

   M1-uppsats, Högskolan i Gävle/Maskinteknik

   Författare :Adam Norell; Darav Hajo; [2023]
   Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

   Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER
