Anionic trash catcher is a cationic quaternary ammonium salt polymer that can be used as anionic trash catchers in the paper making process.It is widely used in reprographic paper,newspaper,enamel paper,chrome paper and kraft,etc.
Anionic trash catcher is a polymer with low molecular weight and high electropositivity. It can bond with the anionic trash and fines in the pulp to neutralize and dissolve negative charges on organic matter and fine fiber surface with high charge density, thus balancing wet end charges and reducing interference of anion impurities.
Anionic trash catcher also helps improve the retention of fillers, fiber fines and wet end chemical aids (sizing agent, cationic starch and strength agent) and improve the single pass retention and filtration rate of paper stock on the net, thus improving the operating performance of paper machine, prolonging the service life of blanket and net, reducing steam consumption for the dryer and increasing paper machine speed and output.
Anionic trash catcher is widely used in manufacturing of kraft paper, corrugated paper, paperboard, textile spool paper, core paper, newsprint, writing culture paper, etc. It can be used alone, or together with our PADE emulsion retention aid, forming two-component retention and drainage system that can deliver better retention results.
