Achieving optimal sizing results with Alkyl Ketene Dimer (AKD) Wax requires a nuanced understanding of its application and optimal processing conditions. NINGBO INNO PHARMCHEM CO.,LTD., a leading supplier of AKD Wax, offers practical advice to paper manufacturers aiming to maximize the benefits of this versatile sizing agent.

1. Proper Emulsification is Key: AKD Wax is typically used in an emulsified form. Achieving a stable, fine-particle dispersion is crucial for uniform sizing. Manufacturers should carefully control the emulsification process, ensuring the correct ratio of AKD Wax to emulsifiers and stabilizers. The use of high-pressure homogenizers can aid in achieving the desired particle size and stability, directly impacting the sizing efficiency and paper quality. Ensuring consistent emulsion quality is a cornerstone of successful AKD wax for papermaking.

2. Temperature Control During Melting: AKD Wax is a solid at room temperature and requires melting before emulsification or direct addition. It is vital to strictly control the melting temperature. Overheating can degrade the AKD Wax, affecting its sizing function and the stability of the emulsion. Typically, temperatures around 47-60°C are recommended, depending on the specific grade of AKD Wax.

3. Dosage Optimization: The amount of AKD Wax used, often referred to as the dosage, needs to be optimized for each specific paper grade and machine condition. While AKD Wax is highly efficient, using excessive amounts can lead to undesirable effects such as stickiness. Manufacturers should conduct trials to determine the ideal dosage that provides the desired water resistance without compromising other paper properties or machine runnability.

4. pH Management: As a neutral sizing agent, AKD Wax performs best in neutral to alkaline pH conditions. Maintaining the appropriate pH level in the papermaking furnish is essential for effective reaction and sizing. Monitoring and adjusting the pH ensures that the AKD Wax molecules react optimally with cellulose fibers, leading to superior water resistance and longevity.

5. Storage and Handling: Proper storage of AKD Wax is important to maintain its quality. It should be stored in a dry, cool, and well-ventilated place, protected from moisture and extreme temperatures. Following the manufacturer's guidelines for shelf life and storage conditions ensures the product remains effective for use.

By adhering to these best practices, paper manufacturers can harness the full potential of AKD Wax to produce high-quality paper products with excellent water resistance and printability. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting its customers with high-performance AKD Wax and the technical expertise needed for successful implementation, reinforcing the value of AKD wax for paper internal sizing.
