The papermaking industry relies on clean water systems and well-preserved raw materials to produce high-quality paper efficiently. Microbial contamination, particularly slime formation, can wreak havoc on machinery, reduce product quality, and lead to costly downtime. DBNPA (2,2-Dibromo-2-cyanoacetamide) has become a key ally for paper mills, offering potent control over these microbial threats.

Understanding Slime in Papermaking

Slime in a paper mill is a pervasive problem caused by the rapid growth of bacteria and fungi in the process water. These microorganisms form biofilms (slime layers) on machine surfaces, in pipelines, and in pulp slurries. This slime can:

  • Cause paper breaks, leading to production interruptions and material waste.
  • Impair drainage on the paper machine, reducing throughput.
  • Cause spots, holes, or streaks in the final paper product.
  • Contribute to corrosion of metal equipment.

Effective slime control is therefore essential for maintaining product quality and operational efficiency.

DBNPA's Role in Slime Control and Preservation

DBNPA's broad-spectrum biocidal activity is highly effective against the types of bacteria and fungi that cause slime in papermaking systems. Its fast-acting nature means it can quickly penetrate and eradicate microbial colonies, preventing slime from forming or breaking down existing deposits.

Beyond process water treatment, DBNPA also serves as a crucial preservative in raw materials and finished products used in the paper industry:

  • Pulp Treatment: Protects pulp slurries from microbial degradation during storage and transport, ensuring consistent material quality.
  • Paper Coatings and Slurries: Prevents spoilage of coating formulations (e.g., containing starch, calcium carbonate, titanium dioxide) that are applied to paper for improved finish and printability. This ensures the coatings remain stable and effective.
  • Adhesives and Binders: Protects water-based adhesives and binders used in paper manufacturing from microbial contamination.

Key Advantages for the Paper Industry

  • Rapid Microbial Elimination: Quickly controls slime-forming bacteria and fungi.
  • Broad Spectrum Efficacy: Tackles a wide range of contaminants.
  • System Cleanliness: Helps maintain clean machine surfaces, reducing paper breaks and improving operational flow.
  • Product Preservation: Extends the shelf life and quality of pulp, coatings, and slurries.
  • Environmental Compliance: Rapidly degrades, meeting discharge regulations.

By effectively managing microbial contamination, DBNPA contributes significantly to the efficiency, product quality, and profitability of papermaking operations.
