Beating enzyme preparation and its preparation method and application

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 [0001] The invention relates to the technical field of papermaking, in particular to a beating enzyme preparation and a preparation method and application thereof. Background technique [0002] As people demand to improve the environment, protect forests, save energy and raw materials, and reduce the cost of papermaking, coupled with increasingly stringent environmental protection requirements, rising prices of papermaking raw materials and energy pressure, the energy saving and emission reduction of papermaking enterprises has caused The attention of governments and enterprises all over the world. The energy conservation and emission reduction of papermaking enterprises can promote the improvement of the concentration of the papermaking industry, promote the adjustment of industrial structure, and help the development of an environment-friendly and resource-saving modern papermaking industry. [0003] Pulping is a very important process in the papermaking p...

Problems solved by technology

However, the increase in the price of commercial pulp and the small increase in the price of paper products have reduced the profit margin of paper products, and it has become more and more difficult for some paper companies to survive. They can only purchase relatively cheap domestic pulp instead of imported pulp to create profits for enterprises.

However, the use of domestic pulp has the risk of lower strength than imported pulp, resulting in a decrease in paper strength, especially the impact on the strength of coated paper

Because the problem of folding and cracking of some coated paper after printing has always been an urgent problem for large and medium-sized coated paper manufacturers. If the strength of the production slurry becomes worse, the problem will become more serious

The strength of paper is mostly improved and improved by chemical strengthening agents, but the effect is limited, the cost is extremely high, and it will also cause problems in paper machine operation and other aspects of paper, such as surface printing performance, anion garbage, etc.
