Tissue Paper Enzymes
INTRODUCTION:
SKHZYE-TPE90 is a complex enzyme preparation intended for modifying cellulosic fibers to improve the compression strength of paper under the proper processing conditions.
SKHZYE-TPE90 is easily added to existing systems without the need of complex or specialized equipment and has a broad range of PH (5.0-8.0) and temperature (22℃-65℃).
PHYSICAL PROPERTIES:
Appearance Tan powder(Note that color does not affect or reflect activity.)
Odor Slight fermentation odor
Solubility: Miscible with water
PH : 6.5 ±0.3
PRODUCT CAPABILITIES:
- Elimination of the need for soda pulping.
- Reduce refining energy. Save refining time and electrical costs.
- Improve paper formation.
- Improvement in WASTEWATER QUALITY. Ehance the drainage rates of papermaking furnishes.
- Improvement of PAPER STRENGTH properties. Enhances inter-fibre bonding by bonding through fibrillation (micro-fibrillation) and avoid fiber breakage.
- 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. Disperse stickies and other contaminants improving paper quality.
- 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.
Case in China:
Item | Blank Group | Test Group(adding 45g/ ton pulp) |
Electricity current | 590.9 | 534.1 |
Thickness | 91.5cm for 142.5kg paper | 93.5cm for 142.5kg paper |
We can see from the test that electricity current is reduced 10%, paper thickness is increased. AU-METE90 help paper mill increse the ecnomic benefits.
RECOMMENDATIONS FOR USAGE:
Effect of Temperature:
It will function around temperature 22oC–65oC with an optimum temperature of 50oC–60oC.Optimum operating temperature results in higher enzymatic activity requiring less dosage of enzyme.
Effect of pH:
It will function from a pH of 4.5–8.5 with an optimum of 6.5-7.5.
Dosage
It is added at a dosage between 10-45 g/ton (metric ton) of dry pulp. It is normally added at the hydropulper to ensure uniform mixing.
As there is an inverse relationship between reaction time and enzyme dosage to obtain a maximum effectiveness, tank levels where enzymatic treatment is performed must be kept at the highest possible level.
ATTENTION:
Can be inactivated by raising the pH above 9.5 or temperature above 65 oC or a combination of the two. It is inactivated in the dryers at the paper machine. No residual enzymatic activity will be found in the manufactured paper.
Packaging
Standard package size for is 20 kilogram plastic drums. Other packaging is available according to the customer’s requirements.
STORAGE:
SKHZYE-TPE90 should be stored in sealed containers and under cool dry conditions. It has a loss of activity of normally less than 10% over one year.
