摘要： Dispersion comprising, in addition to water, from 0.5 to 20% by weight of hydrophobic silica, 0.01 to 10% by weight of a gelling or viscosity-increasing additive, 0.1 to 1% by weight of a preservative and 0 to 1% by weight of a surface-active agent, which comprises, as additional component, at least one insecticide and/or acaricide. It is prepared by dispersing the individual components, successively or together, in the water and, in this connection, deaerating the individual components before and/or during the addition or deaerating the dispersion during the individual dispersing stages. The dispersion can be used as insecticide or acaricide.

摘要： A method and device for producing a finely divided dispersion of solids having a mean particle size of 10 nm to 10 µm, in which at least two flows of a predispersion are sprayed by means of pumps, preferably high-pressure pumps, through one nozzle each into a grinding chamber enclosed by a reactor housing onto a collision point, wherein the grinding chamber is flooded with the predispersion and the finaly divided dispersion is removed from the grinding chamber by the overpressure of the predispersion continuing to flow into the grinding chamber.

摘要： Process for producing ultrafine powders based on polyamides, in which polyamides having a relative solution viscosity ηrel in the range from 1.5 to 2.0, measured in 0.5% strength m-cresol solution at 25°C, are brought into contact with an alcoholic medium in the presence of inorganic particles under superatmospheric pressure and/or elevated temperature to produce an at least partial solution and the polyamide is subsequently precipitated from the at least partial solution, characterized in that a suspension of the inorganic particles suspended in the alcoholic medium is used. The resulting ultrafine polyamide powders have a specific surface area determined by the BET method in the range 5-100 m2/g, a fineness d50 of less than 70 µm; a bulk density BD in the range from 250 to 1000 g/l; and a particle content of from 0.1 to 80% by weight of inorganic particles based on the total weight of the polyamide powder. They are suitable both for coatings and for shaped parts and components having improved mechanical properties.
