The paper manufacturing industry relies on a variety of chemical additives to ensure the quality, efficiency, and sustainability of its processes. Among these, Aluminum Chlorohydrate (ACH) plays a crucial, albeit sometimes underappreciated, role. Known for its versatility in water treatment, ACH also offers significant advantages as a chemical additive in papermaking, primarily functioning as a sizing agent and retention aid. As a dedicated supplier of specialty chemicals, we provide high-quality ACH for the paper industry.

In papermaking, sizing is a critical process that controls the penetration of liquids, such as ink or water, into the paper. Without adequate sizing, paper would be too absorbent, leading to feathering of ink and poor printability. Historically, alum (aluminum sulfate) has been the dominant sizing agent. However, ACH offers several advantages over traditional alum. ACH's high basicity and charge density allow for more efficient interaction with anionic trash and cellulose fibers. This results in improved internal and surface sizing performance, leading to papers with better resistance to liquid penetration and enhanced print quality. For paper mills looking to buy ACH for superior sizing, we offer tailored solutions.

ACH also functions effectively as a retention aid and drainage aid. In the papermaking process, fine particles, fillers (like calcium carbonate or clay), and fibers need to be retained on the forming fabric to maximize yield and improve the paper sheet's properties. ACH helps to bridge these fines and fillers to the larger fibers, improving their retention. This enhanced retention leads to:

  • Improved Yield: Less loss of valuable materials into the white water.
  • Better Sheet Formation: More uniform distribution of fibers and fillers.
  • Enhanced Drainage: Faster water removal from the paper web, allowing for higher machine speeds and reduced energy consumption in drying.
  • Reduced Load on White Water Systems: Cleaner white water, which can be recirculated more effectively.

Furthermore, ACH can help manage 'anionic trash,' which refers to soluble anionic species in the papermaking furnish that can interfere with the performance of other additives like sizing agents and dyes. ACH's cationic nature allows it to neutralize and precipitate these anionic contaminants, improving the overall chemical efficiency of the papermaking process.

The use of ACH can also contribute to cost savings. Its higher efficiency means lower dosage rates are often required compared to traditional chemicals. Additionally, by improving retention and drainage, ACH can lead to higher machine speeds and reduced energy usage in the drying section, contributing to overall operational cost reduction. Paper manufacturers seeking to purchase ACH for enhanced performance and cost efficiency will find our product offerings valuable.
