NINGBO INNO PHARMCHEM CO.,LTD. understands that achieving optimal results with Alkyl Ketene Dimer (AKD) sizing in paper manufacturing requires careful attention to detail. While AKD offers numerous benefits, encountering challenges is not uncommon. This article addresses some of the common issues faced by paper mills and provides practical solutions to ensure effective AKD utilization.

One of the most frequent challenges is inadequate sizing, which manifests as low water resistance in the final paper product. This can stem from several factors, including insufficient AKD dosage, poor retention of the sizing agent on the fibers, or incomplete curing. To address this, NINGBO INNO PHARMCHEM CO.,LTD. recommends optimizing AKD dosage, ensuring the use of appropriate retention aids, and verifying that the drying temperatures and times are adequate for proper AKD curing. Maintaining the correct pH level of the pulp, typically neutral to slightly alkaline, is also critical for AKD efficacy.

Another common issue is poor emulsion stability. This can lead to uneven sizing and inconsistent paper quality. Factors contributing to instability include incorrect preparation of the AKD emulsion, improper storage, or issues with the emulsifying agents. NINGBO INNO PHARMCHEM CO.,LTD. advises rigorous quality control during emulsion preparation and adherence to recommended storage conditions. Reviewing the choice and dosage of emulsifiers is also essential. For reliable results, it is vital to source your AKD from a reputable supplier of AKD like NINGBO INNO PHARMCHEM CO.,LTD.

Deposits on the paper machine can also be a concern. These can arise from excessive AKD usage, interactions with other chemicals, or poor retention. Solutions involve optimizing AKD dosage, enhancing retention strategies, and carefully evaluating chemical interactions within the papermaking system. Regular cleaning and maintenance of the equipment are also crucial preventive measures. The price of AKD should always be considered in conjunction with the potential costs associated with machine downtime due to deposits.

Other challenges like delayed curing or variability in paper quality can be mitigated by fine-tuning machine conditions, such as drying temperatures and pulp consistency. NINGBO INNO PHARMCHEM CO.,LTD. provides technical support to help clients navigate these issues. By addressing these common challenges proactively, paper mills can maximize the benefits of AKD sizing, ensuring consistent production of high-quality paper. For those looking to purchase AKD, choosing a partner with strong technical support is invaluable.
