Usage of Bentonite for papermaking

Usage of Bentonite for papermaking:

 

 

 

1. When using, add cationic polymer at the inlet or outlet of the slurry pump to cause flocculation of paper filler and other components. These large flocs are completely dispersed by high shear force when passing through the slurry pump and pressure screen.

 

2. Bentonite particles are added at the outlet of the pressure screen of the paper machine, which reconnects the dispersed small flocs through the action of charge attraction, thus forming a uniform network of small flocs in the paper pulp. Because the network flocs formed are small and dense, it can not only improve the retention and drainage performance of the paper material, but also greatly improve the evenness of the paper page.

 

3. Before use, it is necessary to dissolve and prepare cationic polymer and bentonite respectively, and then use frequency conversion screw pump to add the prepared solution to each layer of pulp through rotameter control Bentonite manufacturer, Liaoning bentonite
