1. Uneven Paper & Frequent Web Breaks? Proper Papermaking Dispersant Matters Greatly
Uneven fiber distribution, fiber flocculation, surface lumps and frequent web breaks trouble many paper mills during production.
Cationic and anionic polyacrylamide work as papermaking dispersants. They improve fiber dispersion, homogenize pulp distribution, and boost paper formation and strength. They are widely used additives to raise finished product yield and stabilize production.
2. Why Choose Polyacrylamide Specially Formulated for Papermaking
Conventional flocculants tend to cause over-flocculation in papermaking, resulting in fiber agglomeration and uneven paper surfaces.
Special cationic/anionic polyacrylamide for papermaking features molecular weight and charge tailored for pulp conditions. It fully disperses fibers without excessive flocculation. It optimizes paper formation and accelerates drainage to ensure smoother paper forming.
3. Functions of Anionic Polyacrylamide in Papermaking
Anionic polyacrylamide acts mainly as fiber dispersant and retention & drainage aid.
Its negative charges create mild adsorption with pulp fibers and fillers. It lowers loss of fine fibers and fillers, spreads fibers evenly in pulp and reduces flocculation for smoother, finer paper. It speeds up wire section drainage and allows higher machine speed.
4. Applications of Cationic Polyacrylamide in Papermaking
Cationic polyacrylamide fits white water recovery, sludge dewatering and retention assistance.
Its positive charges rapidly capture anionic trash, fine fibers and fillers inside pulp. It increases retention rate and cuts fiber loss in white water. It delivers strong performance in papermaking sludge dewatering and produces drier sludge cakes for easier subsequent treatment.
5. Combined Use of Cationic and Anionic Grades Brings Better Overall Performance
Many paper mills combine cationic and anionic polyacrylamide according to paper grades and production processes.
Anionic PAM disperses fibers and improves paper formation. Cationic PAM enhances retention and purifies white water.
Combined application upgrades paper quality, cuts raw material consumption and reduces wastewater discharge for remarkable comprehensive benefits.
6. Easy Application Without Harming Paper Quality
Polyacrylamide papermaking dispersant is simple to use. Dissolve it proportionally and feed continuously into the pulp system.
It generates little foam and leaves no residues. It will not impair paper brightness, strength or post-processing performance.
Low dosage brings fast results. It causes no equipment corrosion, and operators can handle dosing easily.
7. Suitable for Diverse Papermaking Scenarios to Stabilize Production
Cationic and anionic polyacrylamide apply to cultural paper, packaging paper, tissue paper and specialty paper.
For high-speed paper machines in particular, they effectively reduce web breaks, raise operating speed and improve paper formation. They help mills stabilize production, lift finished yield and cut overall costs.
