摘要:
A mixture for applying a coating includes at least one epoxy ligand and a corresponding hardener in predefined proportions. Said mixture comprises also at least one solid fraction in particles, having dimensions larger than a predetermined minimum value. Said particles are subjected to sintering and subsequently colouring process and are fit to confer a suitable white colouration and almost time invariant. Said mixture also comprises a rheologic product fit to facilitate the application of the coating through the mixture in the fluid state.

Independent claims are included for: (1) preparing the composition, comprising polymerizing the monomers (i) and (ii) in a water-containing solvent, where the water content of the overall reaction mixture is more than 20 wt.%, mixing the polymerization product with the emulsifier and the hydrocarbon or its mixture, and removing the water; and (2) a pulverulent mixture comprising 0.01-50 wt.% of the composition.
摘要:
The invention relates to an addition for producing thermally conductive mortars and structural concrete, said addition being a specific powdery formulation in each case, which, when added as an addition to a conventional concrete or mortar, allows the production of a structural concrete or mortar with improved thermal characteristics (thermal conductivity λ). If the addition is added to a conventional concrete in a plant, a structural concrete with increased thermal conductivities is produced, which can adapt to the thermal requirements of the building, thereby being highly suitable for the heat activation of structures or the geothermal activation of foundations. The concrete containing the addition takes on special rheological characteristics which, inter alia, allows a self-compacting concrete to be produced. If the addition is added to a conventional mortar in a mixer, a mortar is produced with very high thermal conductivities which make it highly suitable for geothermal probes.

摘要:
Method for deposition of solids onto a surface, with one nipple or injector, which contains an ejection opening, being associated to at least one transducer, in such a way that the activation of said transducer, in contact with some of the injector surfaces, produces thereon oscillating or vibrating movements of the surface containing the ejection opening and in such a way that a solid, powdered or granulated material, located therein, is sprayed at the lower side of said nipple or injector through the injector opening and in a direction (z) being perpendicular to the plane in which said opening is located, such that said material is deposited onto a surface situated underneath the injector.
