NINGBO INNO PHARMCHEM CO.,LTD., a leader in chemical supply, is proud to announce the availability of its high-performance Anionic Disperse Rosin Size, a revolutionary product specifically designed to meet the demanding requirements of culture paper production. This advanced chemical auxiliary functions as a superior sizing agent, playing a critical role in enhancing the quality and process efficiency of paper manufacturing.

Paper sizing is a fundamental step in the production process, essential for controlling ink penetration, improving water resistance, and enhancing the overall strength and printability of the final paper product. Traditional sizing methods often present challenges related to stability, environmental sensitivity, and cost-effectiveness. Recognizing these issues, NINGBO INNO PHARMCHEM CO.,LTD. has leveraged advanced chemical technology to develop an anionic high dispersion type rosin emulsion that offers significant advantages.

Our Anionic Disperse Rosin Size is manufactured using first-grade rosin and highly efficient emulsifiers through the most advanced production processes. This results in an emulsion characterized by its exceptional stability. Unlike some conventional sizing agents, this product demonstrates excellent performance without sedimentation or caking throughout its recommended shelf life. This inherent stability is crucial for ensuring consistent application and reliable sizing results batch after batch, minimizing downtime and process variations in the paper mill.

The technical specifications underscore the quality and effectiveness of this product. It presents as a milk white liquid with a solid content typically around 40% ± 2%. Its pH value ranges from 5 to 6, and it exhibits a viscosity of 50 mPa.s Max at 25ºC. A key feature contributing to its high dispersion capability and uniform application is its fine particle size, measured at 0.5 micron Max. This fine particle distribution ensures that the sizing agent is evenly dispersed within the pulp matrix, leading to more consistent sizing across the paper web. The product is identified by CAS No. 25586-20-3 and EINECS 232-475-7, ensuring compliance and traceability.

The application of NINGBO INNO PHARMCHEM CO.,LTD.'s Anionic Disperse Rosin Size is straightforward and adaptable to various paper machine setups. It can be effectively used in both forward sizing and reverse sizing processes. For these methods, it is recommended to dilute the product with cold water to a 2% solution before adding it to the pulp chest. This predilution step facilitates optimal mixing and dispersion within the pulp fiber suspension. For continuous sizing applications positioned ahead of the net, dilution may not be necessary, allowing for direct addition into the process stream.

Achieving optimal sizing results is also dependent on controlling the process environment, particularly the pH value. The ideal pH range for using this anionic rosin dispersion is between 4.5 and 5.5. Careful monitoring and adjustment of pH are essential for maximizing the efficiency of the sizing reaction. Furthermore, the presence of fillers, especially calcium salts commonly used in paper production, can negatively impact sizing effectiveness. It is advised to add fillers approximately twenty minutes after the addition of the anionic rosin dispersion and alum. This sequential addition strategy allows the sizing agent to effectively interact with the cellulose fibers before fillers are introduced, thus preserving sizing performance.

A significant benefit of utilizing NINGBO INNO PHARMCHEM CO.,LTD.'s Anionic Disperse Rosin Size is its ability to significantly improve the properties of the finished paper. By providing excellent control over liquid absorption, it enhances print quality, reduces feathering and bleed-through with various inks, and contributes to improved sheet strength. Moreover, this advanced formulation can effectively replace traditional fortified rosin sizes, often leading to a substantial reduction in production costs without compromising performance. Its efficiency means less product may be required to achieve the desired degree of sizing, offering economic advantages.

The product is conveniently packaged in 200kgs or 1000kgs plastic drums, designed for safe handling and storage. For maintaining its quality and ensuring its long shelf life of 6-12 months, it should be stored in a ventilated, dry, and cool place, ideally between 5°C and 30°C. Proper storage conditions are vital to preserve the emulsion's stability and performance characteristics.
