In modern paper production, chemical additives likepapermaking polyacryalmide are essential for optimizing retention, drainage, and overall machine efficiency. While polyacrylamide is widely known for its high effectiveness, incorrect usage can lead to a range of operational issues. That’s why troubleshooting common problems is vital to maintaining stable production and ensuring high-quality paper output.
Polyacrylamide works by enhancing flocculation—encouraging fine particles, fillers, and fibers to aggregate into larger, manageable clusters. This results in better retention on the forming fabric and faster water removal. However, these benefits can only be realized when the product is selected, dosed, and applied properly. Improper practices can reduce efficiency, cause machine problems, and even affect product quality.
Common Operational Issues and Solutions
Let’s examine some of the most frequently encountered problems related to the use of papermaking polyacrylamide and explore how to address them effectively.
The Importance of Proper Dosing and Mixing
Papermaking polyacrylamide must be diluted properly and dosed evenly across the system. Inconsistent mixing can cause uneven floc size distribution, leading to streaks or blotches in the final sheet. Overflocculation, on the other hand, may result in excessive sludge formation or drainage channel blockage.
Operators should also monitor the pH of the system closely. Polyacrylamide performance is highly pH-dependent. For example, anionic polyacrylamides perform best in neutral to alkaline systems, whereas cationic products are better suited for acidic environments. Running the wrong type under unsuitable conditions often causes paper formation defects and operational instability.
Machine Runnability and Energy Efficiency
Another overlooked area is the impact of polyacrylamide on energy usage. Poor drainage due to floc issues can increase the load on vacuum pumps and extend drying times. By ensuring optimal floc size and system balance, mills can reduce energy consumption while improving speed and consistency.
Moreover, excessive polymer buildup in the system can result in unwanted deposits, leading to wire fouling or press section contamination. Regular cleaning cycles, combined with proper polyacrylamide selection, help extend machine life and reduce downtime.

Understanding these symptoms early can help reduce production losses. For instance, low retention is not always a dosage issue—it may stem from using the wrong charge density (anionic vs. cationic), or poor compatibility with other wet-end additives.The Importance of Proper Dosing and Mixing
