In the competitive landscape of the paper industry, achieving optimal paper strength is paramount. This is where dry strength agents come into play, chemicals designed to enhance the internal bonding of paper fibers. Among the various types available, amphoteric polyacrylamide (AmPAM) has emerged as a highly effective solution for a wide array of papermaking needs. Understanding its properties and optimal application is key to unlocking its full potential.

The primary function of a dry strength agent is to increase the inter-fiber bonding within the paper sheet. This leads to improvements in critical physical properties such as tensile strength, burst strength, stiffness, and fold endurance. Amphoteric polyacrylamide achieves this by utilizing its charged groups to form strong hydrogen bonds and electrostatic interactions with cellulose fibers. This mechanism is particularly beneficial when using lower-grade or recycled fibers, which often have compromised bonding capabilities due to processing. By improving the paper dry strength, manufacturers can use less fiber, reduce refining energy, or incorporate more cost-effective fillers without sacrificing quality.

The application of AmPAM involves careful consideration of dosage, addition points, and compatibility with other process chemicals. Typically, AmPAM is diluted before being added to the pulp slurry, often in the ingredients pool or a high box to ensure thorough mixing. While its amphoteric nature makes it versatile, avoiding mixing with other chemicals during storage and application is crucial to prevent unwanted reactions or performance degradation. NINGBO INNO PHARMCHEM CO., LTD. provides expert guidance on the best practices for applying our AmPAM products to achieve maximum efficacy. Our team can assist in determining the optimal dosage and addition strategy for your specific pulp furnish and machine conditions.

Furthermore, the benefits of using AmPAM extend beyond mere strength enhancement. Its ability to improve retention of fines and fillers contributes to reduced material loss and cleaner process water. Enhanced drainage can also lead to energy savings in the drying section of the paper machine. The combination of these advantages makes AmPAM a cost-effective and efficient solution for papermakers looking to optimize their processes and product quality. We are dedicated to offering competitive pricing for our high-quality dry strength agents, ensuring that our partners can achieve both performance and economic benefits.
