Abstract
The invention discloses a beating enzyme preparation, and a preparation method and application thereof. The beating enzyme preparation is prepared from the following components in percentage by weight: 10%-15% of endo-cellulase, 5%-7.5% of cellobiohydrolase, 0-5% of xylanase, 0.2%-1% of fatty alcohol-polyoxyethylene ether, 0.2%-1% of Tween-80, 0.01%-0.05% of potassium sorbate and the balance being deionized water. Due to the synergistic effect of a plurality of enzymes in the beating enzyme preparation, the power consumption of grinding is greatly reduced, a high fibrillation degree of the fiber surface is achieved, the excessive cutting of strong fibers is avoided, a large fiber length is retained and the folding strength and the tearing strength of paper are improved; meanwhile, a fine fiber retention rate can also be effectively improved, and thus the utilization rate of fiber raw materials can be improved.
Description
Technical field
The present invention relates to pulp technology for making paper, relate in particular to a kind of making beating enzyme preparation and its preparation method and application.
Background technology
Along with people require to improve environment, conserve forests, save the energy and raw material, the cry of reduction papermaking cost grows to even greater heights; add that environmental requirement is more and more stricter, paper making raw material price rises steadily and Pressure on Energy, the energy-saving and emission-reduction of papermaking enterprise have caused the attention of countries in the world government and enterprise.The energy-saving and emission-reduction of papermaking enterprise can promote the raising of paper industry concentration degree, promote industry restructuring, are conducive to the future development of the modernization paper industry of environmentally friendly, resource-conserving.
Making beating, is a very important operation of paper-making process, and making beating needs to consume a large amount of energy, accounts for from timber to becoming paper to produce 15% ~ 18% of total energy consumption.Account for the sulfate wood pulp of global chemical pulp annual production 89%, it is difficult for making beating, needs to consume a large amount of energy, all power consumption 200 ~ 300kWh/ ton slurries, and high shiny beating average power consumption is 250 ~ 500kWh/ ton slurry.Reducing the particularly beating energy consumption of sulfate wood pulp of paper pulp, is a strategic problem of paper industry energy-saving and emission-reduction.Paper industry is energy-conservation two kinds of approach: reduce energy consumption of unit product from management aspect; Utilize new technology to reduce energy consumption of unit product.But the amount of increase of the rise of commercial pulp price and paper product price is less, make the reduction of paper product profit margin, the existence of part papermaking enterprise is more and more difficult, can only replace import slurry by the relatively cheap domestic slurry of buying, for enterprise creates profit.But use domestic slurry to have risk, the especially impact on art paper intensity that strength ratio import slurry is poor, cause paper strength to decline.Because folding explosion problem becomes large and medium-sized art paper manufacturing enterprise urgent need to solve the problem after part halftone paper printing always, if produce pulp strength variation again, that problem will be more serious.More much type art paper paper machines is gone into operation and is discharged the current of production capacity at home, how to guarantee or the quality that improves art paper becomes the most important thing of each large papermaking enterprise.
In prior art, the optimization space of the saving of beating energy consumption from equipment and flow process is minimum.How the intensity of paper is improved by chemical intensifier, but effect is limited, and cost is high, also can bring other aspect problems of paper machine operation and paper, as surface printing performance, anionic trash etc.Therefore by biotechnology Integral lifting paper industry technical merits more clean, energy-saving and environmental protection, the existing situation that changes high energy consumption, high pollution is imperative.
Biotechnology receives more concern, because it can reduce destruction to environment, saves the energy, improve the quality of products.Compared with general abiotic catalyst, enzyme has the features such as mildness, selectivity, high efficiency and adjustability.Improve paper pulp fiber by enzyme preliminary treatment, reduce beating energy consumption, improve paper strength, paid close attention to by many personages that are devoted to papermaking biology enzyme.
Summary of the invention
