Product Overview: In modern papermaking systems, reducing and eliminating the effects of anionic trash is an important condition for ensuring high-speed operation of paper machines, and is also a necessary condition for prioritizing cleaner production in papermaking systems. The fixative has a large amount of positive charge, which can reduce the thickness of the diffusion layer in the electric double layer of the fiber surface, reduce the zeta potential of the paper material, and a large amount of fine fibers contained in the mechanical pulp, and the specific surface area is large, which is strongly preferentially determined, and the fine group is improved. The retention of the fractions; at the same time, the agent can promote the aggregation of the fibers, form a large aggregate, and accelerate the dehydration.
