  2. 6. Thermoset polymers and coatings subjected to high compressive loads

    Author : Daniel Ståhlberg; KTH; []
    Keywords : ;

    Abstract : This study describes the mechanical response of thermosetpolymers under high compressive loads. The study is dividedinto two parts. One part is focusing on the behaviour of apowder coating when used in a clamping force joint and how theproperties varies when varying the physical structure of thecoating. READ MORE

  4. 7. Synthesis and Properties of Branched Semi-Crystalline Thermoset Resins

    Author : Hans Claesson; KTH; []
    Keywords : star-branched; semi-crystalline; comb-branched; ring-opening polymerization; poly ƒÕ-caprolactone ; dendritic; thermoset; low temperature curing; powder coating; UV-curing; poly 5; 5-dimethyl-1; 3-dioxane-2-one ; size exclusion chromatography; rheology;

    Abstract : This thesis describes the synthesis and characterization ofbranched semi-crystalline polymers. Included in this work isthe SEC characterization of a series of dendrimers. Thebranched semi-crystalline polymers were synthesized in order toinvestigate the concept of their use as powder coatings resins. READ MORE

  5. 8. Rheology and UV-curing of a star-branched polyester

    Author : Hans Claesson; KTH; []
    Keywords : Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Abstract : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.

  6. 9. Process Development for Electron Beam Melting of 316LN Stainless Steel

    Author : Stefan Roos; Lars-Erik Rännar; Andrei Koptioug; Jonas Danvind; Lars Pejryd; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; beam deflection rate; electron beam melting; energy input; material properties; microstructure; powder bed fusion; process parameters; 316LN stainless steel;

    Abstract : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

  7. 10. Studies on structure and mechanism at formation of solid solutions and solid dispersions of hydrophobic drugs in polymers

    Author : Marie Wulff; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry; fysikalisk och oorganisk farmaceutisk kemi;

    Abstract : The aim of the studies was to investigate the structures formed and mechanisms involved, when a hydrophobic drug is dispersed in a polymer carrier. The effect of different additives, like surfactants and cyclodextrins, was evaluated. The dispersions were prepared by the melting method. READ MORE
