The performance of paper, particularly its resistance to water and its overall strength, is heavily influenced by the sizing process. AKD (Alkyl Ketene Dimer) is a widely used neutral sizing agent, and its effectiveness hinges critically on the quality of its emulsification. NINGBO INNO PHARMCHEM CO.,LTD. provides essential chemical solutions, including our AKD High Polymer Emulsifier, to ensure paper manufacturers achieve the best possible outcomes.

The fundamental principle of AKD sizing is to impart hydrophobicity to paper. When AKD is applied in an emulsified form, it adheres to the cellulose fibers. During the drying phase of papermaking, the AKD undergoes a chemical reaction, forming a durable, water-repellent film. The success of this process is profoundly dependent on how well the AKD is dispersed and stabilized in the emulsion. An unstable emulsion can lead to uneven sizing, reduced water resistance, and poor retention of the sizing agent on the fibers.

This is where the role of an effective emulsifier becomes indispensable. Emulsifiers work by reducing the surface tension between the AKD wax and water, allowing for the formation of tiny, stable droplets. NINGBO INNO PHARMCHEM CO.,LTD.'s AKD High Polymer Emulsifier is a state-of-the-art cationic polymer designed for this specific purpose. Unlike traditional emulsifiers, it offers superior stabilization, preventing the AKD particles from coalescing. This stability is crucial for maintaining the integrity of the emulsion during transport, storage, and application. The enhanced dispersion ensures that the AKD is evenly distributed throughout the paper sheet, leading to uniform water resistance across the product.

Furthermore, the quality of the emulsifier directly impacts the curing speed and the final paper properties. Our high polymer emulsifier facilitates a quicker curing of the AKD, meaning the paper achieves its optimal water resistance sooner, potentially even before rewinding. This not only improves production efficiency but also ensures that the paper meets performance specifications rapidly. By using a high-quality emulsifier from NINGBO INNO PHARMCHEM CO.,LTD., paper manufacturers can ensure better retention of the AKD, leading to improved paper strength and a more consistent and reliable end product. Understanding the critical function of emulsifiers like our AKD High Polymer Emulsifier is key to optimizing paper properties and achieving manufacturing excellence.
