The paper industry constantly seeks innovative solutions to enhance product performance, and NINGBO INNO PHARMCHEM CO.,LTD. provides essential chemical components that drive these improvements. Alkyl Ketene Dimer (AKD) is a prime example of such a compound, offering multifaceted benefits as a paper chemical auxiliary agent. Its application as a sizing agent is fundamental to achieving desired paper properties, particularly water resistance and printability.

AKD is primarily utilized in two key areas of paper manufacturing: internal sizing and surface sizing. As an internal sizing agent, AKD is introduced into the paper pulp slurry before the sheet formation process. This ensures that the sizing agent is evenly dispersed throughout the paper web, providing a baseline level of hydrophobicity and water resistance. The efficiency of this application is directly linked to the quality of the AKD and the effectiveness of the AKD latex preparation.

In surface sizing, AKD is applied to the surface of the paper after it has been formed and dried. This method further enhances water resistance and can also improve surface strength, smoothness, and printability. By controlling the amount and application of AKD in both internal and surface sizing, manufacturers can fine-tune the properties of the final paper product to meet specific requirements. NINGBO INNO PHARMCHEM CO.,LTD. supplies AKD that is optimized for both application methods, ensuring consistent results.

The underlying principle of AKD's function is its ability to react with the cellulose fibers, creating a hydrophobic layer. This mechanism is central to improving paper water resistance. Unlike older sizing methods, AKD facilitates neutral sizing, which is more compatible with modern papermaking processes and less corrosive to machinery. The AKD neutral sizing agent is thus a more sustainable and efficient choice.

The benefits derived from using AKD are substantial. Enhanced paper printability, as discussed previously, is a major advantage, leading to crisper images and text. Furthermore, the AKD durability for paper ensures that these properties are long-lasting, making AKD ideal for applications requiring archival quality or extended service life. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing AKD that embodies these qualities, supporting the creation of superior paper products.

The AKD synthesis process is designed to yield a compound with consistent chemical properties, ensuring its reliable performance in various papermaking operations. By understanding the detailed AKD chemical properties and adhering to best practices in application, paper manufacturers can fully leverage the capabilities of this essential chemical. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted partner for companies seeking to elevate their paper product quality through the strategic use of Alkyl Ketene Dimer.
