  • Patent number: 8790749
    Abstract: Manufacturing method of grinding surface on glass cosmetics, in particular the nail and skin file, from flat glass of FLOAT type, is carried out by marking at least one abrasive surface on one or two sides of a glass pane or intermediate product. This surface is then coated with fusing glue, powdered with clean quartz sand with grain size between 1 and 500 ?m using a sieve, and the surplus sand is knocked-down. The intermediate product with fixed sand is inserted into the fusing furnace where it is baked at the temperature of up to 900° C. The abrasive surface may be roughened by sand blasting before the fusing glue application; the intermediate product coated with fusing glue can be decorated with glass fritte.

    Abstract: A process of obtaining silicon nitride (Si3N4) surface coatings on ceramic pieces and components by impregnation of the surfaces of the ceramic pieces with silicon powder suspensions with a particle size preferably less than 200 ?m. The thickness of the coatings depends on the impregnation time and on the properties of the slip and the ceramic piece. The subsequent nitridation of the coating by thermal treatment at temperatures between 1300° C. and 1500° C. in N2 atmospheres leads to a continuous Si3N4 coating. The chemical stability and compatibility between Si3N4 and molten silicon enables its application in silicon metallurgy, in manufacturing crucibles for silicon fusion or for housing said molten silicon, in manufacturing pipes and chutes for its transport or in manufacturing different components for its subsequent purification.

  • Patent number: 7638166
    Abstract: Methods of preparing media sheets for inkjet printing applications are provided. In one embodiment, the media sheets can be prepared by dispersing or dissolving inorganic porous particulates and an active ligand-containing organosilane reagent in water; reacting the inorganic porous particulates and the active ligand-containing organosilane reagent to form media coating composition; and applying the media coating composition to a media substrate. In another embodiment, the media sheets can be prepared by coating a media substrate with inorganic porous particulates; dispersing or dissolving an active ligand-containing organosilane reagent in water to form a liquid coating composition; and applying the liquid coating composition to the inorganic porous particulates that has previously been coated on the substrate.

  • Patent number: 7569270
    Abstract: A method for impregnating decorative papers which are used for producing highly abrasion-proof laminate floor materials. The decorative paper is firstly moistened with an amino resin and is thus impregnated. The amount of resin applied is controlled using dosing rollers. In addition, a layer comprised of an amino resin is sprayed with a special dispersion onto the moistened decorative paper. The final mass per unit area with regard to the dry mass of the base paper ranges from 100% to 250%.

  • Patent number: 7563316
    Abstract: The invention relates to a method for producing a coloured sand composition containing a large number of silica sand grains with outer coatings of colour pigments, wherein the method comprises the following steps: mixing caustic soda and water in a predetermined ratio, preferably of 1:2, to form a dilute caustic soda; mixing boric acid in a predetermined concentration with the dilute caustic soda to form a boric acid/caustic soda solution; mixing a binder with the boric acid/caustic soda solution in a predetermined ratio to form a coating mixture; coating the silica sand grains coated with the colour pigments with the coating mixture by adding the coating mixture to the silica sand grains, and indirectly heating the silica sand grains coated with the coating mixture in a system which is spatially sealed from the heating source by means of separate chambers for the heating process and the heating source. A coloured sand composition is also described.

  • Patent number: 7537834
    Abstract: A particle composite including carrier particles having an average diameter of less than 5 ?m. The particle composite is surrounded by a layer made of oxidic material having an irregular surface. Particles, which are made of an active material and which have an average diameter of less than 1 ?m are applied to the layer. The particle composite can be used as a filling substance in polymers and enables the content of active material for comparable properties to be reduced or improves the properties of filled materials, e.g. resistance to aging of elastomers.

  • Publication number: 20080173421
    Abstract: A process for the production of a shell mould, comprising the sequential steps of: (i) dipping a preformed expendable pattern into a slurry of refractory particles and colloidal liquid binder whereby to form a coating layer on the pattern, (ii) depositing particles of refractory material onto the coating, and (iii) drying, steps (i) to (iii) being repeated as often as required to produce a shell mould having the required number of coating layers, characterised in that during at least one performance of step (ii) the particles of refractory material have been pre-mixed with a gel-forming material whereby to coat at least a portion of the refractory particles with the gel forming material such that after contact with the coating layer moisture is absorbed by the gel-forming material thereby causing gellation of the colloidal binder so reducing the time required for drying in step (iii).
