This productis low molecular weight, high electropositivity polymer. It can combine with theanionic garbage and tiny textile filters, neutralize and dissolve the anioncharge on organic matter and filters, balance wet part charge, reduce anionimpurity interferent, improve the retention of tiny fiber and chemicals(sizingagent, cation starch, reinforcer, etc). As well it can improve single-passretention of paper stock on the net, drainage rate, and operation performance,prolong the service life of blankets and net, reduce steam consumption, increasepaper machine running speed and output.
