    摘要: The invention relates to sodium silicates with a modulus (molar ratio of SiO.sub.2 to Na.sub.2 O) of 1.3 to 4 in the form of a fine-particle solid in shard-like form or compounds containing these silicates with the ability to reduce incrustation when used as a builder component in detergents. These useful materials are distinguished in particular by the fact that they are in the form of an X-ray amorphous overdried material (primary drying product) with water contents below 15% by weight and apparent densities of the non-compacted solid granules of 500 g/l or lower which has been produced by drying of a water-containing sodium silicate preparation using a hot gas phase as the drying medium and/or by heating of a spray-dried sodium silicate with water contents of at least 15% by weight at temperatures of 120.degree.to 450.degree. C., if necessary accompanied or followed by the application of forces to produce the shard-like structure. The invention also relates to multicomponent mixtures from the field of solid detergents or multicomponent compounds suitable for this field of application which are characterized by the presence of the sodium silicates defined above.

    摘要: In the production of granules containing anionic surfactants and having a bulk density above 450 g/l by granulation of a surfactant preparation containing a non-surface-active liquid component, the water demand and hence the energy demand for evaporating the water can be reduced if the anionic surfactant in its acid form or a mixture containing one or more anionic surfactants in their acid form and an aqueous alkaline solution are separately treated with a gaseous medium, subsequently sprayed in substantially stoichiometric quantities into the granulation and drying zone either separately or together under a high propellant gas pressure and then granulated and, at the same time, dried, optionally with addition of one or more inorganic or organic solids.

    摘要: A process for the production of washing- and cleaning-active surfactant granules containing 60 to 70% by weight of surfactant and having an apparent density above 500 g/l, wherein a formulation containing a non-surface-active liquid component and having a liquid to paste-like form under normal pressure at temperatures of 20.degree. to 40.degree. C. is introduced to a fluidized bed and granulated and, at the same time, totally or partially freed from the non-surface-active liquid compound, optionally with addition of an inorganic or organic solid, and wherein the granules are discharged from the fluidized bed via a grading step by a countercurrent air-stream which is adjusted so that only particles above a predetermined size are removed from the granules.

    摘要: The process of preparing granules of sodium perborate monohydrate having an increased density by dry-compacting a mixture of sodium perborate monohydrate and from about 0.2 to about 30% by weight of a compacting aid, based on the weight of the mixture. The compacting aid is selected from the group consisting of an alkali metal salt, alkaline earth metal salt, carbohydrate, anionic surfactant, and nonionic surfactant. After forming a compactate of the mixture, the compactate is size-reduced to obtain granules having the desired particle size.
