Brief:Papermaking and dyeing auxiliary agent dosing devices are mainly used for the automatic quantitative dosing of sizing agents, reinforcing agents, retention and filtration aids, bactericides, and cleaning agents during the papermaking process. Multifunctional papermaking auxiliary agents are water-soluble linear polymeric electrolytes copolymerized from acrylamide and modifiers. During papermaking, they can form bridging and cloning with the dispersed pulp phase through various mechanical, physical, and chemical interactions, causing fibers and fillers to interlock and improve paper strength. Furthermore, the polar groups of the auxiliary agent molecules, especially cationic groups, aggregate with anionic groups in the pulp microfibers and talc through adsorption and cloning, forming aggregates that settle on the paper sheet. Additionally, the quaternary ammonium groups in the auxiliary agent reduce the surface tension of the aggregates, fibers, and talc, and decrease the contact angle with water molecules, making it easier for water molecules to detach from the paper wire under stress.
