- the coating substance can be sprayed on a single-component or a two-component nozzle device.
- the storage stability and hygroscopicity, as well as the compatibility with other detergent ingredients, in particular strongly alkaline components can be further improved and the reaction kinetics can be selectively influenced, in this way
- the granules according to the invention are characterized by a very good storage stability in powdered washing, cleaning and
- Sodium sulfate was introduced as a fine free-flowing product in the fluidized bed apparatus in batches and then warmed up by the fluidizing air. After reaching the starting temperature, the liquid metering was started and via a two-fluid nozzle, the liquid mixture containing dimethyl-2,4-di- (pyridyl) -3-methyl-7- (pyridin-2-ylmethyl-3,7-diazabicyclo (3.3.1 ) Nonan-9-one-1, 5-dicarboxylate as a bleach activator and an acid-modified (meth) acrylic acid copolymer (Sokalan CP 13S) as an acidic polymer were atomized into the moving fluidized bed The amount of spray liquid conveyed with a peristaltic pump was detected gravimetrically by means of a balance .
- the inlet air temperature was approximately 95 - set 97 0 C. with the optimal spray performance, a temperature set in a fluidized bed of approx. 64 - 65 ° C, where this temperature level was kept stable after a trial period of about 64.
- a fractionation was carried out by screening off the coarse fractions> 1000 ⁇ m and fines ⁇ 200 ⁇ m n experimental settings, a granule yield of about 90.4% was achieved for the target grain area.
- the bulk density of the granules was about 884 g / l, the abrasion content was 12.9%.
- the final granulate was composed as follows:
- Example 2 Granulation with acidic component and addition of a further additive
- Sodium sulfate was introduced as a fine free-flowing product in the fluidized bed apparatus in batches and then warmed up by the fluidizing air. After reaching the starting temperature, the Fiüsstechniksdostechnik was started and via a two-fluid nozzle, the liquid mixture containing the same bleach activator and the same acidic polymer as in Example 1 and maleic acid (additive) was atomized into the moving fluidized bed. The amount of spray liquid delivered with a peristaltic pump was recorded gravimetrically by means of a balance. The supply air temperature was set to approx. 95 - 97 ° C. With adjustment of the optimum spraying power, a temperature in the fluidized bed of about 65 to 70 ° C.
