SKHZYE-DPE91A

De-inking and Stickies Removal Agent

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

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.Remove the ink in pulp, improve the pulp quality, and enhance the competitiveness in the market.Remove stickies in pulp, improve the pulp quality, and enhance the competitiveness in the market.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.
