Polyacrylamide is used in the production process of white cardboard,copper cardboard,cardboard,typing paper,   and other materials such as wood pulp,straw pulp,and waste paper.It is mainly used as a dispersant,flocculant,     enhancer,microfiber,filler retention agent,and filter aid in the papermaking process.

Retention and filtration aids

Polyacrylamide can increase the retention of web fibers and other wet end additives,accelerate the filtration and dehydration of the web,significantly increase the ash retention rate,and increase the first layer retention rate of fibers by an average of more than 10%,improving the retention of starch and creating favorable conditions for

using starch as an interlayer reinforcing agent.The increase in paper sales profit can also save fillers and significantly improve the filtration performance,thereby ensuring a corresponding increase of 8-10%in rotational speed (average value).Generally speaking,high molecular weight polymers have better retention performance, while low molecular weight polymers have better retention performance.

Enhancer

It can effectively improve the strength of paper and improve its surface properties and printing performance.

Dispersing agent

Can improve the uniformity of paper pages

Flocculant

It can be used as a flocculant in pulp water treatment to remove organic parts from wastewater.When combined with inorganic flocculants,it can precipitate and settle,with a removal rate of 70-80%,reducing the problem of excessive CO2 in wastewater.

Solve the adhesive problem caused by waste paper raw materials.Due to the use of waste paper as raw material, especially the adhesives,additives,and impurities in waste cardboard boxes,they often adhere to the paper machine mesh,blankets,rollers,and drying cylinders,causing serious quality problems in production products.     Polyacrylamide for papermaking can effectively help solve adhesive problems through adsorption,dispersion,and flocculation principles.
