  1. 1. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Shadi Feyzabi; [2023]
    Nyckelord :Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Sammanfattning : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. LÄS MER

  3. 2. Bio-based resins for digital light processing : Mechanical and degradable properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Eklund; Amanda Olofsson Ribrant; [2023]
    Nyckelord :Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

    Sammanfattning : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

  4. 3. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Worabhorn Pathanatecha; [2019]
    Nyckelord :adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

    Sammanfattning : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. LÄS MER

  5. 4. Växtskydd i ekologisk humleodling : i samarbete med föreningen Humlebygget i Näsum

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Beatrice Rosdahl; [2015]
    Nyckelord :humle; Humulus lupulus; Phorodon humuli; Tetranychus urticae; Sphaeroteca humuli; Pseudoperonospora humuli; Föreningen Humlebygget; humletorkan i Näsum; ekologisk odling;

    Sammanfattning : Humle, Humulus lupulus har under lång tid varit en viktig kulturväxt i Sverige. Den klättrande perennen producerar blomställningar som innehåller essentiella oljor och hartser, och används för att smaksätta öl. Förut var öl en mycket viktig källa till vätska och näringsämnen.

  7. 5. Syntes av nya MUF-limmer och analys av dessas härdning i limfog

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Angelica Magnusson; [2015]
    Nyckelord :Adhesive; MUF; NMR; Curing; Raman;

    Sammanfattning : In this project, different MUF resins were synthesized with varying melamine content, F/NH2 molar ratio, number of addition steps and with varying addition order of the reactants during synthesis. Further, it was investigated how these synthesis parameters influenced resin properties including storage stability and free formaldehyde content. LÄS MER
