Alkyl Ketene Dimer (AKD) Wax has become a cornerstone of modern paper sizing, offering enhanced water resistance and improved paper quality. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing high-quality AKD solutions and detailed insights into their effective application. This article delves into the critical factors for AKD sizing, common challenges in troubleshooting AKD paper sizing, and best practices for achieving optimal performance.

The efficacy of AKD sizing is influenced by several key factors. Firstly, the pH of the papermaking system is paramount. AKD performs best in a neutral to slightly alkaline environment, typically between pH 7 and 9. Deviations from this range can significantly impact sizing efficiency. Secondly, the stability and particle size of the AKD emulsion are critical. An unstable emulsion can lead to uneven sizing and reduced performance. NINGBO INNO PHARMCHEM CO.,LTD. ensures the production of stable, high-quality AKD emulsions designed for consistent application.

Thirdly, the curing process is vital. AKD reacts with cellulose fibers through esterification, a reaction that is accelerated by heat. Therefore, the drying section of the paper machine plays a crucial role in the final curing of the AKD, ensuring permanent hydrophobicity. Factors like drying temperature and residence time must be optimized. Lastly, retention aids are often used to ensure that the AKD particles are effectively fixed onto the cellulose fibers, preventing their loss in the process water.

Despite the advantages, papermakers may encounter challenges. Inadequate sizing, often indicated by low water resistance, can stem from insufficient AKD dosage, poor emulsion stability, or incomplete curing. Troubleshooting these issues involves reviewing the AKD dosage, checking the emulsion quality, ensuring the correct pH, and optimizing drying conditions. Poor emulsion stability might require adjustments to the emulsification process or the selection of appropriate stabilizers. Deposits on paper machinery can often be managed by optimizing AKD dosage and ensuring proper retention.
