Pulping method for improving pulping degree of softwood pulp

Abstract

The invention belongs to the technical field of household paper, and particularly relates to a pulping method for improving the pulping degree of softwood pulp. The method comprises the following steps: defibering a softwood pulp board by using a hydraulic pulping machine, carrying out heat preservation treatment by using a treatment liquid, and then carrying out pulping with the cooperation of agrinding material. Compared with the prior art, the method provided by the invention has the following advantages that high-temperature soaking treatment is carried out on the softwood pulp board defibering material by using the treatment liquid, the fibers can be swelled, fine fibers are generated or fibers are refined, the fiber structure is destroyed, the effective components of the treatment liquid can enter the inner part of the fibers for forming an amorphous area in the fibers, the combination among the fibers is weakened, then with the cooperation of the use of the grinding material, the fiber surfaces can be further activated and relaxed, and under the mechanical force, the fibers can be easily cut off and fibrillated, so that the improvement of the pulping degree of the softwoodis facilitated.

Description

technical field [0001] The invention belongs to the technical field of household paper, and in particular relates to a beating method for improving the beating degree of softwood pulp. Background technique [0002] Household paper has developed rapidly in recent years, and the share of toilet paper is also increasing. While calling for preventing overcapacity of toilet paper, relevant experts have also begun to pay attention to the production cost of toilet paper. In order to reduce the production cost of the factory and increase the factory's production cost Production efficiency, more and more paper mills use biological enzymes to pretreat the pulp during the beating process. After the pulp is made into paper, the various physical properties cannot be changed while reducing energy consumption during the beating process. Although toilet paper Most of the raw materials are hardwood pulp, but there are also a few products that add some softwood pulp in order to improve the qu...

[0002] Household paper has developed rapidly in recent years, and the share of toilet paper is also increasing. While calling for preventing overcapacity of toilet paper, relevant experts have also begun to pay attention to the production cost of toilet paper. In order to reduce the production cost of the factory and increase the factory's production cost Production efficiency, more and more paper mills use biological enzymes to pretreat the pulp during the beating process. After the pulp is made into paper, the various physical properties cannot be changed while reducing energy consumption during the beating process. Although toilet paper Most of the raw materials are hardwood pulp, but there are also a few products that add some softwood pulp in order to improve the quality. Because the beating degree of softwood pulp is difficult to improve, the existing method uses biological enzymes to assist beating, but the improvement effect is not ideal.
