The papermaking industry relies on a variety of chemical additives to ensure product quality, process efficiency, and environmental compliance. Cationic Polyacrylamide (CPAM) is one such versatile polymer that plays a crucial role in several stages of papermaking. Offered by NINGBO INNO PHARMCHEM CO.,LTD., CPAM provides significant benefits, from improving paper strength to treating wastewater streams.

In papermaking, CPAM functions primarily as a dry strength agent and a retention aid. As a dry strength agent, it enhances the internal bonding of paper fibers, leading to improved tensile strength, burst strength, and fold endurance of the final paper product. This is achieved through the polymer's ability to form strong bridges between cellulose fibers. As a retention aid, CPAM helps retain fine fibers, fillers (like clay or calcium carbonate), and sizing agents within the paper sheet during the forming process. This not only improves the paper's quality and reduces material loss but also leads to cost savings by minimizing the discharge of valuable components into the white water system.

The white water treatment in papermaking is another area where CPAM demonstrates remarkable efficacy. White water, which is the water recycled from the papermaking process, often contains suspended fines, fillers, and residual chemicals. CPAM helps to flocculate these suspended solids, allowing for their separation and subsequent reuse or discharge. By clarifying the white water, CPAM contributes to a more closed-loop system, reducing water consumption and minimizing the discharge of pollutants. This improved water management is vital for sustainability and regulatory compliance in the industry.

Furthermore, CPAM's flocculation properties are beneficial in the deinking process of recycled paper. It helps aggregate ink particles and other contaminants, facilitating their removal from the pulp, which results in a cleaner and brighter recycled paper product. The effectiveness of CPAM in these applications stems from its ability to interact with various charged species present in the papermaking slurry, including anionic components from the pulp and fillers.

The selection of the appropriate CPAM grade is crucial for optimizing its performance in papermaking. Factors such as molecular weight and charge density influence its interaction with fibers and fines. NINGBO INNO PHARMCHEM CO.,LTD. provides a range of CPAM products tailored to meet the specific needs of different papermaking processes, ensuring maximum efficiency and cost-effectiveness. Investing in high-quality CPAM can lead to tangible improvements in paper quality, reduced operational costs, and a more environmentally sound papermaking operation.
