SKHZYE-DPE91A
Enzymes for Office Waste Paper De-inking Applications
Preface
Ink and fibre on waste paper attach tightly, it is very hard to remove the ink by ordinary methods. SKHZYE-DPE91A could improve the de-inking ability remarkably, and reduce the alkali dosage by 10%-15%, obviously enhance pulp output and quality of pulps, as well as improve the pulp production performance, which is significantly important in relieving the shortage of paper making resources, and lightening secondary pollution led by recycling of waste paper.
SKHZYE-DPE91A is extracted from several mixed special enzyme. It is a powder preparation, with a wide scope of application.
The manufacture process including the following steps: cultivate the kind of special patent bacteria in bioreactor (fermenter); isolate concentrated clarified liquor from culture medium; we get the product, a light hazel powder after refining.
Process
The product act preferentially on the joint of ink and fibre in waste paper, make the link between ink and fibre become loose, get the ink and fibre easy to separate from each other, promote the removal of ink particles; then, appropriate mechanical action should be taken to make the ink particles and fibre separate completely, improve the drainability and strengthen of de-inking pulp
Benefits
1. Use together with de-inking chemical agents，the product could improve the de-inking treatment ability remarkably, so as to enhance the economic and social benefits for the enterprise.
2. Obviously increase the drainability of pulp, which could clean the paper machine cloth, decrease residual oilstain obviously, reduce cloth washing frequency, prolong the cloth service life, and accelerate the operation and runnability of paper machine. Create benefits for the enterprise.
3. The COD in waste water produced during the process of de-inking is lower by 20%-30% compared with conventional de-inking, so the load of waste water treatment system is much lower, which greatly lightened the environment pollution caused by chemical de-inking.
4. Paper machine closed loop recirculating water became obviously clean, caused the reduction in waste water treatment fees or water volume added. Create benefits for the enterprise.
5. As the link between fibre became multipoint connection after brooming, the paper’s tensile, breaking and tearing strength all get improved; more over, the tiny fibers attached again to the long fibers after brooming, further improved the paper quality and strength. Create benefits for the enterprise
6. Due to the reinforcement of abrasion resistance，it could reduce the high quality raw material ratio. Create benefits for the enterprise.
7. Decrease the dosage of starch for papermaking or other chemical auxiliaries, such as alkali, soda, peroxide and silicate. Create benefits for the enterprise.
8. Enhance the strength of short fibre, reduce high quality raw material ratio, and create benefits for the enterprise.
9. Steamheat from dry paper part goes up obviously, which results in the steam dosage saving. Create benefits for the enterprise.
10. SKHZYE-DPE91A make the fibre interior loose, so as to easier fiber rewetting and swelling. Fiber becomes soft after rewetting and swelling, which could save energy when millstone makes defibrination.

Storage
SKHZYE-DPE91 retains the specified activity within at least 6 months when stored below 25℃. The activity would last longer in case of much lower temperature than 25℃. But the product can not be frozen.
Handling and Safety
SKHZYE-DPE91A is non-toxic and biodegradable. However, we should avoid the unnecessary contact. Long-term exposure to protein based products such as SKHZYE-DPE91A may make certain individuals allergic.
Technical service
Sukahan(Weifang)Bio-Technology Co., Ltd will always help our customers use the product properly.
