  1. 1. Enhancing the durability of fluorocarbon-free Durable Water Repellant (DWR) formulation

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

    Författare :Meron Solomon; [2017]
    Nyckelord :Hydrophobicity; textile coating; cross-linker; nanoparticles; surface roughness;

    Sammanfattning : The focus of the project was to alter and optimize the water repellant textile coating formulations to reach enhanced durability. For this purpose, the project was approached with three methods. Firstly, bio-based components were implemented in the mother emulsion to act as surfactant and crosslinking agent and to provide hydrophobic properties. LÄS MER

  3. 2. Skräddad mikrostruktur av gadolinium zirkonat baserade värmebarriärbeläggningar som utsätts för termisk cyklisk utmattning

    Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Författare :Cliff Hamatuli; [2017]
    Nyckelord :Suspension Plasma Spray; Gadolinium Zirconate; Thermal cyclic fatigue;

    Sammanfattning : Yttria Stabilized Zirconia (YSZ) is the standard ceramic top coat material used for TBC application. Above 1200°C, issues such as CMAS (Calcium Magnesium Alumino Silicates) infiltration susceptibility, phase instability and high sintering rates limits its long durability. LÄS MER

  4. 3. Measuring material properties of thin films with DIC and tearing test of laminate

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Peter Nilsson; [2017]
    Nyckelord :DIC; Thin polymer films; Laminated tearing;

    Sammanfattning : Thin polymer materials are today widely used in industry and production. An ordinary food package can have around six different layers of materials laminated together to obtain the desired protection. To obtain an efficient usage of these materials simulations are often required. LÄS MER

  5. 4. Fe-Mo-oxide of spinel structure for methanol oxidation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maria Thulin; [2016]
    Nyckelord :iron molybdate catalyst; methanol oxidation; Fe-Mo-oxide; spinel structure; formaldehyde catalyst; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The aim of this master thesis was to investigate a Fe-Mo-oxide catalyst of spinel structure for methanol oxidation to produce formaldehyde and determine if the spinel could be an alternative to the commercial Formox catalyst used today. This included firstly, synthesising the catalyst to get more knowledge of the formation of the structure and secondly, determine the activity, selectivity to formaldehyde and stability of the catalyst.

  7. 5. Hydrophobic Coating on Cellulosic Textile Material by Betulin and a Betulin Based Polymer

    Master-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Tianxiao Huang; [2016]
    Nyckelord :Betulin; biorefinery; cellulose; contact angle; copolymer; hydrophobicity; marketing strategy; standard spray test; textile fibers; water repellency.;

    Sammanfattning : Betulin is a naturally abundant compound in the outer bark of birch and can be easily obtained by solvent extraction. Herein, solutions of betulin were used to treat cellulosic textile fibers and improve their water repellency. Cotton fabrics impregnated in a 7. LÄS MER
