AKD Sizing Agent: A Deep Dive into its Mechanism and Benefits
Alkyl Ketene Dimer (AKD) has become a cornerstone in modern papermaking, primarily for its efficacy as a neutral sizing agent. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical supplier in China, delves into the mechanism and benefits that make AKD sizing agents indispensable for producing high-quality paper.
The core of AKD's function lies in its reactive nature. AKD molecules possess a lactone ring that undergoes an esterification reaction with the hydroxyl groups (-OH) present on cellulose fibers within the paper pulp. This chemical reaction is key to forming a robust, hydrophobic layer. The long alkyl chains of the AKD molecule are then oriented towards the exterior, creating a surface that repels water and other aqueous solutions. This process is fundamental to achieving 'paper sizing with AKD'.
The benefits derived from this mechanism are manifold. Firstly, it provides excellent water resistance, a critical property for various paper grades, from packaging to printing and archival papers. This superior water repellency is often sought after by manufacturers looking for 'high water resistance in paper'. Secondly, the esterification reaction leads to durable sizing, meaning the water-repellent properties are long-lasting and resistant to degradation over time, contributing to the archival quality of paper.
AKD sizing agents are particularly advantageous because they function optimally in neutral to alkaline pH conditions. This characteristic aligns with modern papermaking trends that favor less corrosive environments, benefiting machinery and reducing the environmental impact associated with acidic processes. Consequently, many mills actively seek 'neutral sizing agents for paper'.
