Anionic Polyacrylamide Emulsion for Papermaking Retention Aid with Binary Retention and Drainage High-Efficiency Polymeric Coagulant in Water-in-Oil Emulsion

Anionic Polyacrylamide Emulsion For Binary Retention and Drainage

Anionic polyacrylamide (APAM) emulsion is a water-in-oil (W/O) or inverse emulsion polymer with anionic charge (typically via carboxylate groups), designed specifically for the binary retention and drainage (R&D) system in the pulp and paper industry. It acts as a high-efficiency polymeric coagulant/flocculant to improve fiber/filler retention, accelerate water drainage, and enhance paper machine runnability.

1. Emulsion Dilution: Dilute the APAM emulsion with clean water (1:100–1:500 dilution ratio) under low-shear mixing to avoid polymer chain scission.
2. System Setup: Add the cationic primary coagulant first at the thick stock inlet, followed by the APAM emulsion at the thin stock outlet (before the headbox).
3. Dosing Rate: Typically 0.05–0.3 kg/t of dry pulp (adjust based on pulp type, filler content, and white water quality).
4. Monitoring: Track first-pass retention (FPR), drainage time (e.g., Schopper-Riegler value), white water turbidity, and paper formation.

• Ease of Use: No dust, no time-consuming dissolution process, reduced operator exposure risk.
• Consistent Performance: Uniform particle size and active content, minimizing batch-to-batch variability.
• Cost Efficiency: Lower dosing rate due to higher molecular weight and better dispersion.
• Handling Safety: Non-dusty, less prone to static electricity, easier to store and transport.

O/W Retention Aid Polyacrylamide for Paper Making to Improve Firbe Retention
Paper Making Retention Aid/Dispersants
Paper making retention aid could help improve the retention of fiber, padding, fiber fines and other chemical, creating clean and steady wet chemical environment. It could help lower the consumption of pulp and other chemical, lower the production cost, improve the paper quality and improve production efficiency of paper machine. Good retention aid is the key factor for paper machine smooth production and good quality of paper. High molecular weight PAM suit a wide range of pH.
