Papermaking Dispersant Solutions: Enhancing Sheet Formation and Production Efficiency

In the papermaking process, uneven distribution of fibers and fillers often leads to poor sheet formation, such as cloudiness or basis weight variation, directly impacting final product quality and convertibility. Meanwhile, fiber flocculation in the pulp not only reduces production efficiency but may also increase equipment wear and energy consumption. How to economically and effectively improve pulp dispersion to achieve a more uniform and stable sheet structure is a core challenge for many production teams.

Addressing these common pain points, Chemi Tech introduces a series of high-performance papermaking dispersant solutions. Our products feature unique molecular designs that create stable steric hindrance or electrostatic repulsion on the surfaces of fibers and fillers, effectively preventing their re-flocculation and ensuring uniform distribution within the stock system. This significantly improves both macro and micro sheet formation, enhancing properties like opacity, smoothness, and printability. It also reduces the risk of web breaks, allows for higher machine speeds, thereby directly boosting production line efficiency and economic returns.

Our solution implementation follows clear steps: First, our technical team conducts a diagnostic analysis of the customer's existing stock system, water quality, and process conditions to identify key factors affecting dispersion. Second, based on the analysis, the most compatible dispersant type or blend is selected or tailored from the Chemi Tech product portfolio. Subsequently, simulated application tests are performed in the laboratory to precisely determine the optimal addition point and dosage. Finally, we provide on-site application guidance and process parameter optimization suggestions to ensure the dispersant functions stably and efficiently during paper formation, with continuous follow-up on performance.

For instance, a cultural paper producer in East China previously struggled with unstable sheet formation, particularly with fiber flocks appearing on the surface of low-basis-weight grades. After adopting a customized anionic dispersant from Chemi Tech and optimizing the addition process by precisely feeding it into the fan pump inlet, pulp dispersion improved markedly. Production data showed that the sheet formation index increased by approximately 30%, basis weight variation narrowed, and dewatering on the wire section became more uniform. This allowed for a slight increase in machine speed and resulted in well-controlled overall production costs. The customer expressed satisfaction with the stability and consistency of the final paper quality.
