Because PEI is highly cationic, a small amount of it can be added to the pulp to agglomerate fine fibers, and the drainage and retention of the pulp can be achieved.

effect:

Improve the retention of fine fibers and fillers

Improve water filtration effect

Enhance paper strength

Improve the fixing rate of fillers and reinforcing agents

Reduce water use for white water purification

Reduce the burden of drainage treatment equipment
