For professionals in the paper industry, understanding the nuances of chemical additives is key to optimizing production. AKD Wax, a staple in neutral sizing, comes in various grades, with 1840, 1865, and 1895 being among the most common. Knowing the differences between these grades can help you make informed purchasing decisions and select the most suitable AKD Wax supplier for your operations.

What Differentiates AKD Wax Grades?

The numbering system for AKD Wax grades (1840, 1865, 1895) primarily relates to the chain length and composition of the fatty acids used in their synthesis. Generally, these numbers correspond to increasing chain lengths or different combinations of fatty acid precursors. This variation in composition impacts several key properties:

  • Melting Point: Higher grade numbers often correlate with higher melting points. For example, AKD 1895 typically has a higher melting point than AKD 1840. This can affect the ease of emulsification and the curing process during paper drying.
  • Reactivity and Sizing Efficiency: While all AKD grades are effective sizing agents, subtle differences in their molecular structure can influence their reactivity with cellulose and the resulting hydrophobicity. Some grades might offer slightly better initial sizing or faster cure rates.
  • Stability: The stability of the AKD emulsion and the finished paper product can also be influenced by the grade of AKD Wax used.

Choosing the Right Grade for Your Application

The choice between AKD 1840, 1865, and 1895 often depends on specific paper manufacturing requirements:

  • AKD 1840: Often considered a versatile grade, suitable for a broad range of applications, including cultural paper and general packaging. It typically offers a good balance of performance and cost.
  • AKD 1865: This grade might be preferred for applications requiring slightly improved initial sizing or better performance at higher machine speeds. It's a popular choice for many standard paper grades.
  • AKD 1895: Typically associated with higher melting points and potentially enhanced performance in specific conditions, such as certain coating applications or where a more robust hydrophobic barrier is needed.

Purchasing Considerations from a Supplier

When you approach an AKD Wax manufacturer or supplier, such as NINGBO INNO PHARMCHEM CO.,LTD., it's essential to discuss your specific needs. Ask about the typical applications and recommended grades for your paper type. A knowledgeable supplier will guide you based on your desired outcomes, whether it's improved water resistance for packaging paper, enhanced printability for cultural paper, or cost-effectiveness for high-volume production.

Understanding these grade differences allows you to buy AKD Wax that is precisely suited for your papermaking process. Always consult with your supplier to ensure you are selecting the optimal AKD Wax grade for maximum efficiency and quality in your production.
