While the Department of rosin sizing agent mainly dycosacryl Rosin and anionic Rosin, traditional anionic Rosin unable to realize the true neutral sizing, cationic Rosin preparation must use the more expensive dycosacryl emulsifers and zephiramine rolling.low complex, preparation process strictly, thus making the higher manufacturing costs, and the adoption of polymer low surface active agents as emulsifers, with the help of other dycosacryl retention agent, reducing the dependence of the aluminum sulfate, implements the anionic Rosin's fully neutral sheet, or even isoporous Department of manufacturing, as Rosin neutral's pet.
