Method for producing translucent paper through beating enzymes

Abstract

The invention discloses a method for producing translucent paper through beating enzymes. The method comprises the steps of preparing a beating enzyme preparation formula and the like. A method for adding the beating enzymes is adopted for improving a translucent paper producing process, operation is easy and convenient, and energy consumption is reduced. The selected beating enzymes are from a composite biological enzyme preparation, fibers in paper making raw materials can be effectively treated, and the quality of finished paper can be improved. The structural property of the fibers is changed through the beating enzymes, the fibers are swelled or layered and become thinner, the brooming rate of the fibers is increased, the beating degree and wet weight of pulp can be increased more easily in the beating process, and therefore the strength, transparency and the like of the translucent paper are improved. The fiber structure of the pulp is changed, the fibers are promoted to be swelled, fracturing of cell walls is accelerated, the brooming rate of the fibers is increased, and the number of cut-off fibers is reduced. The utilization rate of the short fibers is increased, that is, hardwood pulp boards are increased to 70% from 40%. When the translucent paper is produced, it is required that under the same beating degree, the power consumption per ton of paper is reduced by 220 kw / h.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a method for producing translucent paper by using beating enzyme. Background technique [0002] Paper is formed by interweaving and fixing plant fibers or other fibers, and plant fibers or other fibers are needed in the raw materials required for papermaking. The thickness, length, and wall thickness of fibers in the pulp all have an impact on the paper, especially for translucent paper. Translucent paper is a kind of paper with low weight, high transparency and high strength, and the paper requires good evenness. The fine fibers and the fibrillation of the fibers can improve the strength of the paper, the optical properties of the paper, and the quality of the paper. Smoothness and evenness. In order to ensure that the fibers in the pulp can be shortened, a higher beating degree and wet weight are required during the beating process, so the beating degree must be increas...

Problems solved by technology

In order to ensure that the fibers in the pulp can be shortened, a higher beating degree and wet weight are required during the beating process, so the beating degree must be increased, but the power consumption during the beating process is relatively increased
