Амфотерный крахмал
Merging the dual characteristics of cationic and anionic starches, our Amphoteric Starch offers exceptional versatility and process control throughout the papermaking workflow. It enhances both fiber bonding and filler dispersion while providing adjustable rheological properties tailored to diverse processing requirements. With its forward-thinking design, this starch aligns with both current environmental regulations and the evolving demands of next-generation papermaking technologies.

Особенности продукта
Amphoteric starch has two active groups, anionic and cationic, with high dispersibility and solubility. The paste is transparent, stable, and not easy to age. It is used for wet-end addition in papermaking, with significant enhancement effect. It can effectively improve the retention rate of fine fibers and fillers, improve the water filtration performance of pulp, effectively balance the system charge, eliminate the system anionic garbage, improve the operation performance of paper machines, and is conducive to the reuse of white water and reduce production costs. Compared with single cationic starch, it has the advantages of less addition, wide application conditions, and strong applicability.
