| 摘要 |
The present invention relates to a method for producing an emulsion of alkenyl succinic anhydride (ASA) in an aqueous solution of cationic amylaceous material; this process does not implement a loop for recirculating the product at the level of the emulsifying unit, and performs a dilution of the emulsion once the latter has been produced; a product which has a particle size that is simultaneously fine, monodisperse and stable over time is achieved. An effective process which is simple to implement, in particular on a paper production site, for providing an emulsion which may be stored during the periods when the paper machine is stopped for cleaning or maintenance operations, is thus provided. |
