Advantages of AKD Emulsion Over Traditional Sizing Agents
In the evolution of papermaking technology, sizing agents have seen significant advancements, moving from traditional methods to more efficient and environmentally friendly options. NINGBO INNO PHARMCHEM CO.,LTD. sheds light on the distinct advantages that AKD emulsion offers over older, traditional sizing agents, particularly rosin-based systems.
Traditional sizing agents, often based on rosin and requiring acidic conditions, have historically been used to impart water resistance to paper. However, these acidic conditions can lead to paper degradation over time, making documents brittle and prone to yellowing. Furthermore, the acidic nature of rosin sizing can cause corrosion issues in paper machinery. In contrast, AKD emulsion excels in neutral to slightly alkaline pH conditions. This operational pH range is not only gentler on paper and machinery but also aligns with more sustainable papermaking practices. The neutral/alkaline sizing achieved with AKD results in papers with better archival stability and extended longevity, crucial for high-quality printing and writing papers.
The performance benefits of AKD are numerous. AKD provides a more effective and uniform sizing effect, leading to superior water and ink holdout. This translates directly into improved printability, reduced paper dusting, and enhanced dimensional stability. While AKD might have a higher initial cost than some traditional agents, its efficiency at lower dosages and the reduced need for other auxiliary chemicals often result in a lower overall cost in use. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that the purchase of AKD is an investment in superior product quality and process efficiency.
From an environmental perspective, AKD is generally considered more favorable. Its biodegradability and the fact that it does not necessitate the use of strong acids reduce the chemical burden on wastewater and minimize potential pollution. The improved machinery lifespan due to reduced corrosion also contributes to a lower environmental footprint. As the paper industry increasingly focuses on sustainability, the advantages of AKD emulsion in terms of performance, paper longevity, and environmental impact make it the preferred choice for modern papermakers. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing these advanced solutions to meet the evolving needs of the industry.
