  1. 1. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Nyckelord :;

    Sammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER

  3. 2. Storage period optimization of a viscous nasal spray suspension

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lili Zsófia Domián; [2023]
    Nyckelord :Rhinocort; viscosity; rheology; thixotropy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. LÄS MER

  4. 3. Analysis of granulated carbide powder and how it affects pressing

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Nyckelord :Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Sammanfattning : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. LÄS MER

  5. 4. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Malin Eriksson; [2022]
    Nyckelord :dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

    Sammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER
