This product is a low molecular weight strong cationic polymer that combines with anionic waste and fine materials in the slurry, neutralizing dissolved organic matter and negative charges on the surface of small fibers with high charge density, thereby balancing wet end charges, reducing interference from anionic impurities, and promoting the retention of fillers, fine fibers, and wet end chemical additives such as sizing agents, cationic starch, and reinforcing agents. And it can improve the one-way retention rate and filtration rate of the web paper material, enhance the operational performance of the paper machine, and extend the service life of the net and blanket. Reduce the amount of steam used in the dryer, increase vehicle speed and output.This product can be widely used in the production of kraft linerboard, corrugated paper, box board paper, bobbin paper, core paper, newsprint, culture paper and other paper machines. It can be used alone or in combination with our company's PDAE lotion retention aid to form a two-component retention and drainage aid system to achieve more retention aid effects.
