Process for Producing Dispersible Powders |
| 摘要 |
A process for producing dispersible powders by spray-drying aqueous polymer dispersions and adding antiblocking agent, wherein antiblocking agents present in agglomerated form and having a particle size from 10 μm to 250 μm, or having a particle size from 5 mm to 5 cm in the case of agglomerates in the form of extrudates, are fed in whole or in part by a transport gas into the spray-drying device and are comminuted to a particle size from 0.01 μm to 5 μm, or, in the case of extrudates, to a particle size from 2 μm to 60 μm. |

1. A process for producing a dispersion powder by means of spray-drying of aqueous polymer dispersions and addition of antiblocking agent, wherein antiblocking agents present in agglomerated form and having a particle size of 10 μm to 250 μm, or having a particle size of 5 mm to 5 cm in the case of agglomerates in the form of extrudates, are supplied to the spray-drying wholly or partly by means of a conveying gas and are comminuted to a particle size of 0.01 μm to 5 μm or, in the case of extrudates, to a particle size of 2 μm to 60 μm.
