The choice of sizing agent significantly impacts the quality, longevity, and production efficiency of paper. While rosin has historically been a dominant player, AKD Wax has emerged as a superior alternative, particularly in modern papermaking environments. NINGBO INNO PHARMCHEM CO.,LTD., a leading AKD wax manufacturer China, provides insights into why AKD wax is the preferred choice over rosin sizing agents.

The primary difference between AKD Wax and rosin sizing lies in their operational pH. Rosin sizing agents typically require acidic conditions (pH 4.5-6.0) to function effectively. This can lead to issues such as corrosion of machinery and potential degradation of paper over time, manifesting as yellowing and brittleness. In contrast, AKD Wax is a neutral sizing agent, performing optimally in neutral to alkaline conditions (pH 7.0-8.5). This broader pH compatibility not only reduces machine corrosion but also contributes to longer-lasting, more stable paper products. This is a key reason why many paper mills choose to buy AKD wax.

Stability and durability are other critical areas where AKD wax excels. Rosin-based sizes can be susceptible to hydrolysis in alkaline environments, diminishing their sizing effectiveness. AKD wax, however, forms a stable covalent bond with cellulose fibers through esterification. This reaction creates a durable hydrophobic layer that is resistant to degradation, ensuring consistent water resistance over the paper's lifespan. As an experienced AKD wax manufacturer China, NINGBO INNO PHARMCHEM CO.,LTD. ensures our product's stability for maximum performance.

Beyond fundamental performance, AKD wax offers other advantages. It is highly compatible with alkaline fillers like calcium carbonate, which are often used in modern paper production to improve brightness and reduce cost. Furthermore, AKD wax can improve paper strength properties and reduce foam formation, contributing to smoother machine runnability. These combined benefits make AKD wax a more versatile and efficient option for a wide range of paper grades.

In conclusion, while rosin sizing has served the paper industry for decades, AKD Wax presents a more advanced, stable, and versatile solution. Its compatibility with neutral/alkaline conditions, superior durability, and enhanced paper properties make it the clear choice for modern paper manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality AKD wax to help paper mills transition to more efficient and effective sizing technologies.
