Flash Mixing, Fast and Simple Way to Introduce Wet End Additives Efficiently into Papermaking Process

摘要

An immediate and effective mixing with TrumpJet~R Flash mixing process makes it possible to inject papermaking additives e.g. retention aid and sizing chemicals and filler into stock very close to the headbox. The developed versatile mixing technology that exploits efficient transverse mixing principle allows mixing of additives in selected groups into headbox feed stock simultaneously and together with retention aid agent at the same location. As a result the process is simpler, it has a very short response time, chemical consumption can be lower and filler retention can be better and sheet properties develop positively.
