The papermaking industry relies on a precise combination of chemicals to achieve desired paper properties, from strength and brightness to printability and water resistance. Aluminum Chlorohydrate (ACH), a versatile inorganic polymer, plays a significant role in optimizing these characteristics, acting as a key additive in various papermaking processes.

ACH as a Sizing Agent and Retention Aid:

In papermaking, sizing agents are crucial for controlling the penetration of liquids, such as inks and water, into the paper. ACH functions effectively as a precipitating agent for internal sizing chemicals like Alkyl Ketene Dimer (AKD). By forming precipitates that deposit onto the cellulose fibers, ACH enhances the sizing efficiency, leading to improved water resistance and reduced ink feathering. This is vital for producing high-quality printing and writing papers.

Furthermore, ACH acts as a retention aid. It helps to bind fine fibers, fillers (like calcium carbonate or clay), and other additives to the main paper fibers during the papermaking process. This improved retention leads to:

  • Enhanced Pigment Retention: Leading to brighter and more vibrant paper colors.
  • Reduced Loss of Fines: Improving the overall yield of usable fiber and filler.
  • Better Formation: Resulting in a more uniform paper sheet with improved surface properties.
  • Improved Drainage: Facilitating faster dewatering on the paper machine, increasing production speed.

Other Applications in Papermaking:

Beyond its primary roles in sizing and retention, ACH can also assist in removing anionic trash – detrimental substances that can interfere with chemical processes and negatively affect paper quality. Its ability to complex with these substances helps maintain the efficiency of other papermaking additives.
