Definitions
- the invention relates to a method for producing a amorphous alkali silicate / alkali carbonate compounds containing surfactants Secondary washing ability, which as a water-soluble builder in Detergents or cleaning agents can be used, as well as the Use of such alkali silicate compounds in washing or cleaning agents, extruded detergents or cleaning agents and a Process for their production.
- Modern, compacted detergents or cleaning agents generally have the disadvantage that they are due to their compact structure show poorer dissolving behavior in aqueous liquor than, for example lighter spray-dried washing or cleaning agents the state of the art.
- Detergents or cleaning agents tend to do this generally at a slower dissolving rate in water, the higher their degree of compaction.
- Zeolites in Washing or cleaning agents are usually used as builder substances may be included due to their water insolubility contribute to the deterioration in dissolving behavior.
- a water-soluble alternative for the zeolite are amorphous Alkali silicates with secondary washing ability.
- Alkali silicates in granular form with higher bulk densities can according to the teaching of European patent application EP-A-0 526 978 can be obtained, using an alkali silicate solution with a Solids content between 30 and 53 wt .-% in a heated drum brings in the longitudinal axis of a shaft with a variety of arms rotating close to the inner surface of the drum, wherein the drum wall has a temperature between 150 and 200 ° C and the drying process by a gas fed into the drum is supported with a temperature between 175 and about 250 ° C. According to this process, a product is obtained, the middle one Particle size is in the range between 0.2 and 2 mm. A preferred one Drying gas is heated air.
- European patent application EP-A-0 542 131 describes a process in which a product which is completely soluble in water at room temperature and has a bulk density of between 500 and 1200 g / l is obtained. Drying is preferably carried out using heated air.

- a rotor with blade-shaped blades rotates at such a speed that the silicate solution has a solids content of between 40 and 60% by weight pseudoplastic mass with a free water content between 5 and 12 wt .-% arises. Drying is supported by a hot air stream (220 to 260 ° C).
- the older, unpublished application P 44 19 745.4 describes also a water-soluble, amorphous and granular Alkali silicate, which in a similar manner as in EP-A-0 526 978 described is produced, but is siliceous.
- amorphous means "X-ray amorphous”. This means that the alkali silicates have no sharp reflections in X-ray diffraction deliver, but at most one or more broad maxima, the width of which is several degree units of the diffraction angle. However, this does not rule out the fact that in electron diffraction experiments Areas are found that have sharp electron diffraction reflections deliver. This is to be interpreted as the substance microcrystalline areas on the order of up to approx. 20 nm (max. 50 nm).
