I. Enzyme As Viscosity Remover (1) The Bvzyme-VRE enzyme can separate the sticky particles from fibrils, thus, the adhesive which contains in the suspended material can be removed easily (2) Gentle neutral pH pulping keep sticky particles large so that many can be screened out of the slurry, alkaline pulping increases the tackiness and solubility of the adhesives during conventional alkaline treatment. II. Enzymes As Pulping Assistant Based on the effect of Bvzyme-PPA enzyme on the pulp fiber, it can enable the fiber fully expanded by absorbing adequate water and promote fiber brooming, thus, the energy consumption in the subsequent pulping process will be reduced by 20%-50% III. Enzymes As Starch Modifier The Bvzyme-STM enzyme is used as the starch modifier with the unique features, the currently surface sizing agent of paper is the oxidized starch, but the traditional method of modifying oxidized-starch including many defect such as high cost, difficulties in controlling oxidation degree and environment pollution etc., however, these defect can be conquered by Bvzyme-STM enzyme IV. Enzymes For Office Wastepaper De-inking The chemical deinking agent can be complete replaced by Bvzyme-WPD enzymes, first, the adhesiveness between fiber and ink would be weakened based on the effect of Bvzyme-WPD enzymes onto the fiber surface, second, the ink would complete separated from the fiber by using the suitable mechanism, the work efficiency would be improved and the cost of de-inking process and pollution load would be reduced V. Xylanase enzyme During the pulp cooking process, the xylan which is the major components contains in wood fiber and non-wood fiber would partially dissolved, denatured and re-precipitate onto the fiber surface, however, by application the Xylzyme-PBA enzyme to the cooked pulp can remove a large part of the re-precipitate Xylan, this will increase the pulp matrix porosity and releasing the soluble lignin, therefore, the chemical bleaching agent can easily and effectively penetrate into the pulp, the bleachability of pulp can be increased accordingly, the Xylzyme-PBA enzyme can reduce the using amount of chemical agent by 15%-50% Welcome to contact Bevenovo Co.,Ltd. for more information, your interesting is highly appreciated
