    摘要： A method of concentrating an aqueous dispersion comprising organic polymer particles and silicon dioxide particles comprising the steps of: a) providing an aqueous dispersion comprising organic polymer particles and silicon dioxide particles, the dispersion having an initial content of organic polymers and an initial content of silicon dioxide; b) contacting the dispersion of step a) with a creaming agent to yield an aqueous serum phase and an aqueous concentrated phase, and c) separating the serum phase from the concentrated phase. The invention further relates to a concentrated aqueous silicon dioxide dispersion which is obtained by a method according to the invention and to the use of such a dispersion as an adhesive.

    摘要： A spray nozzle 10 for a laser deposition apparatus, comprises an elongate nozzle aperture 16, a powder supply chamber 18 in fluid communication with the elongate nozzle aperture and upper and lower elongate gas apertures 26, 28 located above and below the elongate nozzle aperture respectively and extending substantially parallel to the elongate nozzle aperture. In use the powder supply chamber supplies powder to the nozzle aperture under pressure so as to cause a wide powder stream to be ejected from the nozzle aperture and the upper and lower elongate apertures eject a wide gas stream above and below the wide powder stream. When used with a laser deposition apparatus 10 a relatively wide coating of a substantially uniform thickness can be deposited.

    摘要： A method for the preservation of natural rubber latex is disclosed which comprises adding to natural rubber latex at least one hydrophobically modified saccharide in combination with at least one conventional preservative, preferably ammonia.
    The method enables increasing the stability of natural rubber latex by an economically interesting method which does not negatively affect neither subsequent conventional processing of the latex, nor the properties of shaped rubber articles manufactured from the stabilized latex.
    Furthermore, preserved rubber latex is disclosed that is stabilized by the method of the invention. Also preserved non-concentrated as well as concentrated rubber latex is disclosed comprising at least one said hydrophobically modified saccharide in combination with at least one conventional preservative, preferably ammonia.
