Refining enzyme Sinzym PRL is complex enzyme preparations intended for use as refining enhancers in papermills using virgin and recycled fibers (inclusive of other lignocellulosic wastes). It is easily added to existing systems without the need of complex or specialized equipment and has a broad pH and temperature tolerance.
Main feature:
- 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

Dosage:
the optimal dosage is generally 30-100g for per ton of dry pulp, but it could be changed with the different furnish, process temperature, pH and retention times.

Storage:

the enzyme activity could keep over 80% for 12months if store under the below condition:

1. Keep away from sunlight and rainwater during transportation and storage

2.Keep in a dry and well-ventilated environment below 25℃
