High-strength modified energy-saving biological enzyme paper pulp and pulping process

Abstract

The invention discloses high-strength modified energy-saving biological enzyme paper pulp and a pulping process thereof. The paper pulp comprises 0.5-5 parts of an antibacterial agent, 1-3 parts of a toughening agent, 1-5 parts of a thickening agent, 40-60 parts of regenerated paper pulp, 10-20 parts of a packing, 1-5 parts of a defoaming agent, 2-8 parts of a stabilizing agent, 1-3 parts of a retention aid, 10-30 parts of fibers and 5-20 parts of biological enzyme. According to the paper pulp, a biological enzyme technique is adopted for beating the pulp, and the biological enzyme with the high pertinence is selected for performing synchronous pulp beating treatment on the pulp, so that not only is the energy consumption reduced and is the yield increased, but also the fibers can be modified, for example, when wood pulp beating enzyme is adopted to be matched with the beating of the wood pulp, the beating degree is improved, the fiber strength is ensured, and the power consumption in beating each ton of the pulp is reduced; when the biological enzyme is adopted for beating OCC pulp, the beating degree is reduced, the fiber strength is improved, the drainability, the pulp beating capability and the flowability of the fibers are improved, and meanwhile, the production energy consumption is reduced, the properties of the pulp are improved, and thus the quality of paper is improved.

Description

technical field [0001] The invention relates to a pulp and a pulping process thereof, in particular to a bioenzyme high-strength modified energy-saving pulp and a pulping process. Background technique [0002] As we all know, pulp is processed from certain plants as raw materials. It is the basic raw material for papermaking. Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used; Different purity is divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. Generally used in the manufacture of paper and cardboard. In addition to being used for the manufacture of specialty papers, refined pulp is often used as a raw material...

AI Technical Summary

Problems solved by technology

[0003] The current pulping process adopts the traditional beating operation, the traditional high-strength beating, the power consumption is large, the pulping degree is high, and the drying process is difficult, so the consumption of steam is also relatively large, and the production output is severely restricted.
