Pulp Paper Resin Control Enzyme Longkey

Product Overview

• Function: Efficiently hydrolyzes ester/amide groups in resinous/sticky contaminants (e.g., adhesives, pitch) into water-soluble acids and alcohols. Reduces deposition on papermaking equipment, improves production efficiency, and enhances product quality.
• Mechanism: Breaks down hydrophobic adhesives into hydrophilic fragments via β-elimination and nucleophilic substitution.

Key Features

1. Broad pH Compatibility: Effective in pH 3.0-9.0 systems.
2. Thermostability:
   • Operating Range: 25-70°C
   • Optimal Range: 40-55°C
3. Eco-Friendly: Biodegradable formulation.
4. Production Benefits:
   • Reduces "stickies" deposition on wires, felts, and dryer cylinders.
   • Extends service life of dryer fabrics and doctor blades.
   • Eliminates wax spots/defects, improving sheet quality.
   • Enhances dryer fabric permeability, lowering steam consumption.
