Chemical Description

 

  • Alkyl Ketene Dimer (AKD) is used as a sizing agent in the paper industry, enhancing water resistance and paper quality.
  • Available in two forms: solid wax and white liquid (emulsion).
  • The liquid form can be added directly to paper pulp, simplifying the application process.
  • It provides a permanent sizing effect that improves paper durability and does not degrade over time.
  • AKD reduces ink absorption, enhancing print quality with sharper and more vibrant prints.
  • It contributes to the paper's strength and stiffness, making it more durable.
  • The liquid form offers advantages in ease of use, with no need for equipment to melt the wax.
  • It allows for flexible integration into various paper manufacturing processes.
  • The emulsion form ensures consistent quality and uniform application across the paper pulp.
  • Liquid AKD may require specific storage conditions to maintain stability and effectiveness.
  • Both forms of AKD support the production of environmentally friendly paper by reducing effluent problems and corrosion to equipment.
  • The effectiveness of AKD depends on factors like the type and amount used, and the conditions of the papermaking process.
  • AKD is a key component in producing high-quality paper products, including printing and writing papers, packaging materials, and specialty papers.
  • AKD enhances the recyclability of paper by not significantly affecting the paper's ability to be reprocessed.
  • It is less corrosive compared to traditional sizing agents like rosin and alum, extending the lifespan of paper manufacturing equipment.
  • The use of AKD aligns with sustainability goals in the paper industry by contributing to the production of lower-impact paper products.
  • Liquid AKD simplifies the dosage and mixing process, providing precise control over the sizing agent's distribution in the pulp, leading to uniform paper quality.
  • The emulsion form of AKD eliminates the variability associated with the physical state changes of solid waxes, offering more predictable processing outcomes.
  • It is suitable for a wide range of paper products, from everyday printing and writing papers to specialized applications like packaging materials resistant to moisture and grease.
  • AKD's hydrophobic layer not only resists water but also helps in protecting the paper from other liquid substances, enhancing the versatility of paper products.
  • The adaptability of liquid AKD to various papermaking technologies makes it a versatile choice for modern, automated paper mills seeking efficiency and consistency.
