Brief Introduction

It is an enzyme preparation intended for use in reducing stickies in recycled pulps. Properly applied microbial enzyme-based products can enhance the release of stickie particles from the fiber surface and facilitate its removal by flotation.  

It is a powdered form of a blend of cellulase and other enzymes operating between a broad range of pH (4.5-9.0) and temperature (25-70°C) and is used in the range of 180-360 g/ton of dry pulp.

Packaging

25,200,1000kgs/plastic drum in bulk

Dosage

180-360 g/ T pulp (normally added at the hydropulper to ensure uniform mixing)

Advantage

Primary Benefits (Stickies Removal) 

• Elimination of the need for soda pulping. Neutral pulping can be used.
• Improvement in quality.
• Improved stickies removal efficiency.
• Lower cost (higher contamination) raw materials can be utilized.
• Reduction in downtime due to cleaning and sheetbreaks.
• Improves quality of process water. Lower COD, less toxic and contain fewer micro-stickies
• Greater customer satisfaction 

Secondary Benefits  

• Elimination of the need for soda pulping.
• Reduction in REFINING ENERGY. Reduction in Refining time or Amperage leading to a reduction in electrical costs.
• Improvement in FIBRE YIELD. Increase in fines retention from increased fibrillation (micro-fibrillation). Helps to reduce build-up of fines in forming and press fabrics, increasing fabric life.
• Improvement in WASTEWATER QUALITY. Reduction of fines and the cleaning of white water loops.
• Improvement of PAPER STRENGTH properties. Enhances paper strength by increasing inter-fiber bonding through fibrillation (micro-fibrillation).
• Improvement in MACHINE RUNNABILITY. Cleaner whitewater system helps to reduce slime build up that causes sheetbreaks.
• Reduction in STEAM LOADING or INCREASE IN PAPERMACHINE SPEED. Improvement in drainability leading to either the reduction of steam demand for paper drying or conversely increases in the paper machine speed.
• Improvement in PAPER QUALITY. Improvement in paper formation due increased fines retention and more efficiently refined pulp. Reduction in vessel picking during printing of paper produced with hardwood virgin pulp.
• Savings in RAW MATERIAL costs. Allows the use of lower quality and cheaper furnishes.
• Savings in CHEMICAL costs. Reduction in consumption of retention aids and strength enhancing chemicals.
