The papermaking industry relies on precision and efficiency to produce high-quality paper products. Among the critical chemical additives that contribute to this, polyacrylamide (PAM) plays a pivotal role, primarily as a retention and drainage aid. As a leading manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides advanced polyacrylamide solutions that enhance papermaking processes, leading to improved product quality and operational cost savings. If you are looking to buy high-performance papermaking chemicals, understanding PAM is essential.

The Critical Functions of Polyacrylamide in Papermaking

In the papermaking process, fine cellulose fibers, fillers (like clay or calcium carbonate), and other additives are suspended in water to form a slurry. The goal is to efficiently drain the water and retain the solids on the forming fabric to create a uniform paper sheet. This is where polyacrylamide excels:

• Retention Aid: PAM, particularly cationic and anionic forms, acts as a flocculant. It helps to aggregate the fine fibers and fillers, preventing them from passing through the forming fabric with the water. This retention of fines and fillers leads to improved paper strength, opacity, and brightness, while also reducing material loss and improving the efficiency of downstream processes like dewatering.
• Drainage Aid: By promoting the formation of larger flocs, PAM also facilitates faster water removal from the forming sheet. This increased drainage rate allows for higher machine speeds, which translates directly to increased production output and reduced energy consumption in drying.
• Flocculation Mechanism: The polyacrylamide polymer chains bridge the gap between individual fibers and filler particles. The specific type of PAM and its charge density are optimized based on the furnish composition (type of pulp, fillers used) and processing conditions to achieve the most effective flocculation without causing excessive foaming or issues with the machine's felt.

Optimizing PAM Selection for Your Mill

Choosing the correct polyacrylamide is crucial for achieving the desired results. Factors to consider when you plan to buy PAM include the type of pulp being used (e.g., hardwood, softwood, recycled fiber), the fillers employed, the pH of the system, and the specific paper grade being produced. For instance, cationic PAM is often used in neutral to alkaline papermaking, while anionic PAM might be preferred in acidic conditions or with specific filler types. Our expertise as a manufacturer allows us to guide you in selecting the most suitable product for your mill's unique requirements.
