Pam Chemical Water Treatment Anionic Polyacrylamide Used in Papermaking

Anionic polyacrylamide is a commonly used papermaking aid in paper mills. High molecular weight anionic PAM is used as a flocculant to flocculate wastewater from paper mills. It is also used as a suspending agent and lubricant in long-fiber pulp and paper. Among them, it increases the viscosity of the slurry, acts as a water-soluble lubricant, makes the fibers not entangled, improves the flocculation between the fibers, improves the interweaving ability of the fibers, and strengthens the fibers in the medium. Suspended in the medium to extend the settling time.

The use of low molecular weight anionic polyacrylamide as a dispersant slows down the flocculation and sedimentation of the fiber, makes the fiber evenly distributed in the water, greatly improves the uniformity of the online slurry, and makes it possible to produce under the condition of high beating degree and longer fiber Thinner, better quality paper.
