Achieving optimal sizing efficiency is a continuous pursuit for paper manufacturers aiming for superior product quality. Alkyl Ketene Dimer (AKD) plays a pivotal role in this, and its effectiveness hinges on several factors, from the quality of the raw powder to the stability of its emulsion and the precision of its application. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality AKD raw powder and expert guidance to help producers maximize their sizing efficiency.

The foundation of effective AKD sizing lies in the quality of the AKD raw powder. High purity, minimal acid value, and a suitable iodine value are indicators of good quality AKD powder. NINGBO INNO PHARMCHEM CO.,LTD. ensures its AKD raw powder meets these stringent specifications, providing a reliable base for subsequent processing into emulsions. Factors such as active ingredient content and melting point are also critical, influencing how well the AKD can be melted and emulsified. Understanding these properties allows for better control over the emulsification process, which is the next crucial step in maximizing sizing efficiency.

The conversion of AKD wax powder into AKD emulsion is where many challenges can arise. A stable, well-dispersed AKD emulsion with fine particle size (0.1-1 μm) is essential for uniform application and maximum reactivity with cellulose fibers. Issues like premature hydrolysis, particle agglomeration, or inadequate emulsifier systems can drastically reduce sizing efficiency. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of controlled processing conditions, including precise temperature management during melting and homogenization, and the correct use of cationic emulsifiers. Proper emulsification ensures that the AKD is available to react with the fibers efficiently during the drying phase.

The application technique of the AKD emulsion also directly impacts sizing efficiency. Factors such as dosage, addition point in the wet end, and compatibility with other papermaking additives must be carefully considered. For instance, improper dosage can lead to either under-sizing or over-sizing, while interactions with anionic substances or excessive fines can hinder AKD's effectiveness. NINGBO INNO PHARMCHEM CO.,LTD. offers technical support to help clients optimize their application protocols. This includes recommendations on how to balance retention aid usage and manage wet-end chemistry to ensure the AKD is effectively retained and fixed onto the fibers.

In conclusion, maximizing sizing efficiency with AKD requires a holistic approach, starting with high-quality raw materials and extending through meticulous emulsion processing and optimized application. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted partner in this endeavor, providing premium AKD products and the expertise needed to achieve superior water resistance and overall paper performance. By focusing on these key considerations, paper manufacturers can unlock the full potential of AKD in their production processes.
