1.This surface sizing enzyme is for use as refining enhancers.
2.In papermills using virgin and recycled fibers.

Surface Sizing Enzyme LPK-CR 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.

 

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.

Properties

Solubility:               Miscible with water

pH (1% solution):  4.5 + 1.0

 

Dosage

Surface Sizing Enzyme LPK-CR is added at a dosage between 30-100 g/ton (metric ton) of dry pulp. We have found a general optimum at 50 g/ton. Contact your representative for further assistance on determining optimal dosage for your mill. The enzymatic treatment is normally performed at the digester.

 

As there is an inverse relationship between reaction time and enzyme dosage to obtain a maximum effect, tank levels where enzymatic treatment is performed must be kept at the highest possible level while maintaining adequate mixing.
