Application method of Bentonite for papermaking

Application method of Bentonite for papermaking:

 

1. When using, the cationic polymer shall be added at the inlet or outlet of the slurry pump to cause the flocculation of paper filler and other components, which will be completely dispersed by high shear force when passing through the slurry pump and pressure screen.

 

2. Liaoning bentonite particles are added at the outlet of the pressure screen of the paper machine. Through the charge attraction effect, they connect the scattered small flocs from the beginning, thus forming a uniform network of small flocs in the paper pulp. Because the network flocs formed are small and dense, they can not only improve the retention and drainage performance of the paper material, but also greatly improve the uniformity of the paper page.

 

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